•	Expand the types of facilities and/or programs to which an acute care hospital or distinct unit can transfer an eligible client and receive a prorated diagnosis related group (DRG) payment from the department;
•	Add clarifying language that the department uses the per diem payment method to pay for hospital stays that have insufficient data available to determine stable relative weights and for other specified specialty services;
•	Add language that the department may adjust the DRG conversion factor when directed by the legislature to achieve budgetary targets;
•	Add language that the department may adjust the per diem rate when directed by the legislature to achieve budgetary targets;
•	Add language that the department may adjust a per case payment when directed by the legislature to achieve budgetary targets;
•	Put in rule how per diem rates are determined for chronic pain services;
•	Remove "emergency services" from the title of WAC 388-550-4000 and clarify that the section applies to both emergency and nonemergency services provided by out-of-state hospitals;
•	Add language that the department may adjust the outlier threshold or the percentages of outlier adjustment factors when directed by the legislature to achieve budgetary targets;
•	Reduce the total period allowed for resubmission or modification of a claim, other than a prescription drug or major trauma claim, from thirty-six months to twenty-four months from the date of service, effective with dates of services or admission on and after July 1, 2009;
•	Add language specifying a three-hundred sixty-five-day limit for resubmission or modification of a claim for major trauma services, consistent with the limit set in WAC 388-550-5450 and 388-531-2000; and
•	Update, clarify, and rearrange current language for improved readability.

     (3) Providers must submit ((their)) the initial claim to ((MAA)) the department and have an internal control number (ICN) assigned by ((MAA)) the department within three hundred sixty-five calendar days from any of the following:

     (a) The date the provider furnishes the service to the eligible client;

     (b) The date a final fair hearing decision is entered that impacts the particular claim;

     (c) The date a court orders ((MAA)) the department to cover the service; or

     (d) The date the department certifies a client eligible under delayed certification criteria.

     (4) ((MAA)) The department may grant exceptions to the time limit of three hundred sixty-five((-day time limit)) calendar days for initial claims when billing delays are caused by either of the following:

     (a) The department's certification of a client for a retroactive period; or

     (b) The provider proves to ((MAA's)) the department's satisfaction that there are other extenuating circumstances.

     (5) ((MAA)) The department requires providers to bill known third parties for services. See WAC 388-501-0200 for exceptions. Providers must meet the timely billing standards of the liable third parties in addition to ((MAA's)) the department's billing limits.

     (6) When a client is covered by both medicare and ((MAA)) medicaid, the provider must bill medicare for the service before billing ((medicaid)) the initial claim to the department. If medicare:

     (a) Pays the claim the provider must bill ((MAA)) the department within six months of the date medicare processes the claim; or

     (b) Denies payment of the claim, ((MAA)) the department requires the provider to meet the three hundred sixty-five-day requirement for timely initial claims as described in subsection (3) of this section.

     (7) ((MAA allows providers to)) The following applies to claims with a date of service or admission before July 1, 2009:

     (a) Within thirty-six months of the date the service was provided to the client, a provider may resubmit, modify, or adjust any claim, other than a prescription drug claim or a claim for major trauma services, with a timely ICN ((within thirty-six months of the date the service was provided to the client)). This applies to any claim, other than a prescription drug claim or a claim for major trauma services, that met the time limits for an initial claim, whether paid or denied. ((MAA)) The department does not accept any claim for resubmission, modification, or adjustment after the thirty-six-month period ends.

     (a) No increased payment from the TCF is allowed for an otherwise qualifying trauma claim that is resubmitted after three hundred sixty-five calendar days from the date of service.

     (b) Resubmission of or any adjustments to a trauma claim for purposes other than receiving TCF payments are subject to the provisions of this section.

     (12) The three hundred sixty-five-day period described in subsection (11) of this section does not apply to overpayments from the TCF that a trauma care provider must refund to the department. A provider must refund an overpayment for a trauma claim that received payment from TCF using a method specified by the department.

     (13) If a provider fails to bill a claim according to the requirements of this section and the department denies payment of the claim, the provider or any provider's agent cannot bill the client or the client's estate. The client is not responsible for the payment.

[Statutory Authority: RCW 74.08.090 and 42 C.F.R. 447.45. 00-14-067, § 388-502-0150, filed 7/5/00, effective 8/5/00.]

     (1) The department pays hospitals for medicaid and SCHIP inpatient hospital services using the rate setting methods identified in the department's approved state plan as follows:

Payment method used for medicaid and SCHIP inpatient hospital claims	Applicable providers/services	Process to adjust for third-party liability insurance and any other client responsibility
Diagnosis related group (DRG) negotiated conversion factor	Hospitals participating in the medicaid hospital selective contracting program under waiver from the federal government	Lesser of either the DRG billed amount minus the third-party payment amount and any client responsibility amount, or the allowed (([amount])) amount, minus the third-party payment amount and any client responsibility amount.
DRG cost-based conversion factor	Hospitals not participating in or exempt from the medicaid hospital selective contracting program	Lesser of either the DRG billed amount minus the third-party payment amount and any client responsibility amount, or the allowed (([amount])) amount, minus the third-party payment amount and any client responsibility amount.
Ratio of costs-to-charges (RCC)	Some services exempt from DRG payment methods	The allowable minus the third-party payment amount and any client responsibility amount.
((Costs-to-charges rate with a "hold harmless" settlement provision)) Ratio of costs-to-charges (RCC) subject to cost settlement	Hospitals eligible to be paid through the certified public expenditure (CPE) payment program	((For the "hold harmless" settlement, the lesser of the billed amount minus the third-party payment amount and any client responsibility amount, or the allowed amount minus the third-party payment amount and any client responsibility amount.)) The payment made is the federal share ((only)) of costs after deducting any third party payment amount and any client responsibility amount.
Single case rate	Hospitals eligible to provide bariatric surgery to medical assistance clients	Lesser of either the billed amount minus the third-party payment amount and any client responsibility amount, or the single case rate allowed amount minus the third-party payment amount and any client responsibility amount.
Fixed per diem rate	Long-term acute care (LTAC) hospitals	Lesser of either the billed amount minus the third-party payment amount and any client responsibility amount, or the per diem allowed amount minus the third-party payment amount and any client responsibility amount.
Per diem rate	Some providers/services exempt from the DRG payment methods	Per diem allowed amount, and for some services a high outlier amount, minus the third-party ((payer)) payment amount and any client responsibility amount.
Cost settlement	DOH-approved critical access hospitals (CAHs)	The allowed amount, subject to retrospective cost settlement, minus the third-party payment amount and any client responsibility amount.
Medicaid base community psychiatric hospitalization rate	Nonstate-owned free-standing psychiatric hospitals located in Washington state	Paid according to applicable payment method in WAC 388-550-2650 for medicaid and SCHIP clients, minus the third-party payment amount and any client responsibility amount.

     See WAC 388-550-4800 for payment methods used by the department for inpatient hospital services provided to clients eligible under state-administered programs. The department's policy for payment on state-administered program claims that involve third-party liability (TPL) and/or client responsibility payments on claims is the same policy indicated in the table in subsection (1) ((in)) of this section. However, to determine the department's payment on the claim, state-administered program rates, not medicaid or SCHIP rates, apply when comparing the lesser of either the billed amount minus the third-party payment and any client responsibility amount, or the allowed amount minus the third-party payment amount and any client responsibility amount.

     (2) In response to direction from the legislature, the department may change any one or more payment methodologies outlined in chapter 388-550 WAC for the purpose of achieving the legislature's targeted expenditure levels. The legislative direction may take the form of express language in the biennial appropriations act or may be reflected in the level of funding appropriated to the department in the biennial appropriations act. In response to this legislative direction, the department may calculate an adjustment factor (known as an "inpatient adjustment factor") to apply to inpatient hospital rates.

     (a) The inpatient adjustment factor is a specific multiplier calculated by the department and applied to existing inpatient hospital rates in order to meet targeted expenditure levels as directed by the legislature.

     (b) The department will apply the inpatient adjustment factor when the department determines that its expenditures on inpatient hospital rates will exceed the legislature's targeted expenditure levels.

     (c) The department will apply any such inpatient adjustment factor to each affected rate in a proportional manner.

     (3) The department's annual aggregate medicaid and SCHIP payments to each hospital for inpatient hospital services provided to medicaid and SCHIP clients will not exceed the hospital's usual and customary charges to the general public for the services (42 CFR Sec. 447.271). The department recoups annual aggregate medicaid and SCHIP payments that are in excess of the usual and customary charges.

     (((3))) (4) The department's annual aggregate payments for inpatient hospital services, including payments to state-operated hospitals, will not exceed the estimated amounts that the department would have paid using medicare payment principles.

     (((4))) (5) When hospital ownership changes, the department's payment to the hospital will not exceed the amount allowed under 42 U.S.C. Section 1395x (v)(1)(O).

     (((5))) (6) Hospitals participating in the department's medical assistance program must annually submit to the department:

     (a) A copy of the hospital's CMS medicare cost report (form 2552-96) that is the official "as filed" cost report submitted to the medicare fiscal intermediary; and

     (b) A disproportionate share hospital (DSH) application if the hospital wants to be considered for DSH payments. See WAC 388-550-4900 for the requirements for a hospital to qualify for a DSH payment.

     (((6))) (7) Reports referred to in subsection (((5))) (6) of this section must be completed according to:

     (a) Medicare's cost reporting requirements;

     (b) The provisions of this chapter; and

     (c) Instructions issued by the department.

     (((7))) (8) The department requires hospitals to follow generally accepted accounting principles.

     (((8))) (9) Participating hospitals must permit the department to conduct periodic audits of their financial records, statistical records, and any other records as determined by the department.

     (((9))) (10) The department limits payment for private room accommodations to the semiprivate room rate. Room charges must not exceed the hospital's usual and customary charges to the general public as required by 42 C.F.R. Sec. 447.271.

     (((10))) (11) For a client's hospital stay that involves both regional support network (RSN)-approved voluntary inpatient and involuntary inpatient hospitalizations, the hospital must bill the department for payment, unless the hospital contracts directly with the RSN. In that case, the hospital must bill the RSN for payment.

     (((11))) (12) Refer to subsection (1) of this section for how the department adjusts inpatient hospital claims for third party payment amounts and any client responsibility amounts.

     (3) A DRG payment includes all covered hospital services provided to a client during days the client is eligible, but is not limited to:

     (a) An inpatient hospital stay.

     (b) Outpatient hospital services, including preadmission, emergency room, and observation services related to an inpatient hospital stay and provided within one calendar day of a client's inpatient hospital stay. These outpatient services must be billed on the inpatient hospital claim (see WAC 388-550-6000 (3)(c)).

     (c) Any specific service(s), treatment(s), or procedure(s) (such as renal dialysis services) that the admitting hospital is unable to provide and:

     (i) The admitting hospital sends the client to another facility or provider for the service(s), treatment(s), or procedure(s) during the client's inpatient hospital stay; and

     (ii) The client returns as an inpatient to the admitting hospital.

     (d) All transportation costs for an inpatient client when the client requires transportation to another facility or provider for a specific service(s), treatment(s), or procedure(s) that the admitting hospital is unable to provide and:

     (i) The admitting hospital sends the client to another facility or provider for the service(s), treatment(s), or procedure(s); and

     (ii) The client returns as an inpatient to the admitting hospital.

     (4) The department's allowed amount for the DRG payment is determined by multiplying the assigned DRG's relative weight, as determined in WAC 388-550-3100, by the hospital's specific DRG conversion factor. See WAC 388-550-3450. The total allowed amount also includes any high outlier amount calculated for claims. ((See WAC 388-550-3450 and 388-550-4600(4))).

     (5) When directed by the legislature to achieve targeted expenditure levels, as described in WAC 388-550-2800(2), the department may apply an inpatient adjustment factor to each hospital's specific DRG conversion factor rate used in calculating the DRG payment.

     (6) The department's DRG payment to a hospital may be adjusted when one or more of the following occur:

     (a) For dates of admission before August 1, 2007, a claim qualifies as a DRG high-cost or low-cost outlier, and for dates of admission on and after August 1, 2007, a claim qualifies as a DRG high outlier (see WAC 388-550-3700);

     (b) A client transfers:

     (i) Before July 1, 2009, from one acute care hospital or distinct unit to another acute care hospital or distinct unit; or

     (d) A client has third party liability coverage at the time of admission to the hospital or distinct unit;

     (e) A client is eligible for Part B medicare and medicare has made a payment for the Part B hospital charges; or

     (f) A client is discharged from an inpatient hospital stay and, within seven calendar days, is readmitted as an inpatient to the same hospital. The department or its designee performs a retrospective utilization review (see WAC 388-550-1700) on the initial admission and the readmission(s) to determine which inpatient hospital stay(s) qualify for DRG payment. Upon the department's retrospective review, an outlier payment may be made if the department determines the claim for combined hospital stays qualifies as a high-cost outlier or high outlier. See WAC 388-550-3700 for DRG high-cost outliers and high outliers.

     (((6))) (7) For dates of admission on and after July 1, 2009, the department pays inpatient claims assigned by the all-patient DRG grouper (AP-DRG) as cesarean section without complications and comorbidities, at the same rate as the vaginal birth with complicating diagnoses.

     (8) The department does not pay for a client's day(s) of absence from the hospital.

     (((7))) (9) The department pays an interim billed hospital claim or covered inpatient hospital services provided to an eligible client only when the interim billed claim meets the criteria in WAC 388-550-2900.

     (((8))) (10) The department applies to the payment for each claim all applicable ((claim payment)) adjustments for client responsibility, any third party liability, medicare, ((etc., to the payment)) and any other adjustments as determined by the department.

     (ii) The client returns as an inpatient to the admitting hospital.

     (d) All transportation costs for an inpatient client when the client requires transportation to another facility or provider for a specific service(s), treatment(s), or procedure(s) that the admitting hospital is unable to provide when:

     (i) The admitting hospital sends the client to another facility or provider for the service(s), treatment(s), or procedure(s); and

     (ii) The client returns as an inpatient to the admitting hospital.

     (((4))) (5) The department ((has established)) establishes an average length of stay (ALOS) for each DRG classification during the rebasing process. The DRG ALOS is used as a benchmark to authorize and pay for inpatient hospital stays that are exempt from the DRG payment method. See WAC 388-550-4300(6).

     (((5))) (6) The department's per diem payments to ((hospitals)) a hospital may be adjusted when one or more of the following occur:

     (a) A claim qualifies as a per diem high outlier claim (see WAC 388-550-3700). The outlier provision does not include a claim grouped to a DRG classification in a specialty service category. The specialty ((services)) service categories include psychiatric, rehabilitation, detoxification, and CUP program services. Long term acute care (LTAC), administrative days and swing bed days do not qualify for high outlier payment((;)).

     (b) A client is not eligible for a medical assistance program on one or more of the days of the hospital stay((;)).

     (c) A client has third party liability coverage at the time of admission to the hospital or distinct unit((;)).

     (d) A client is eligible for medicare, and medicare has made a payment for the hospital charges((; or)).

     (e) A client is discharged from an inpatient hospital stay and, within seven calendar days, is readmitted as an inpatient to the same hospital or a different hospital. The department or its designee performs a retrospective utilization review (see WAC 388-550-1700) on the initial admission and the readmission(s) to determine which, if any, inpatient hospital stay(s) qualify for payment. An outlier payment may be made if the department determines the claim for the combined hospital stays qualifies as a high outlier. (See WAC 388-550-3700 for high outliers.)

     (f) When directed by the legislature to achieve targeted expenditure levels, as described in WAC 388-550-2800(2), the department may apply an inpatient adjustment factor to the per diem rate payments.

     (((6))) (7) The department does not pay for a client's day(s) of absence from the hospital.

     (((7))) (8) The department pays an interim billed hospital claim for covered inpatient hospital services provided to an eligible client only when the interim billed claim meets the criteria in WAC 388-550-2900.

     (((8))) (9) The department applies to the payment for each claim, all applicable ((claim payment)) adjustments for client responsibility, any third party liability, medicare, ((etc., to the payment)) and any other adjustments as determined by the department.

     (a) Inpatient chronic pain management as ((indicated)) specified in WAC 388-550-2400;

     (b) Long term acute care (LTAC) hospitals as ((indicated)) specified in WAC 388-550-2595;

     (c) Community psychiatric inpatient hospitalization as ((indicated)) specified in WAC 388-550-2650; and

     (d) Administrative day status, and nursing facility swing bed day status, as ((indicated)) specified in WAC 388-550-4500 as it existed before July 1, 2009 or WAC 388-550-4550 for these services effective for dates of admission on and after July 1, 2009.

     (2) For dates of admission on and after August 1, 2007, the department continues to pay per diem((s)) rates for the services identified in subsection (1), except for the community psychiatric inpatient hospitalization per diem indicated in subsection (1)(c).

     (3) For dates of admission on and after August 1, 2007, with the exception of community psychiatric inpatient services, the department establishes per diem rates for specialty services that are generally based on statewide standardized average cost per day amounts, which are then adjusted to reflect the unique characteristic of hospitals in the state of Washington for payment purposes.

     (a) The department calculates separate statewide standardized per diem rates for the following categories:

     (i) Rehabilitation services--Rehabilitation claims are identified as all claims with a rehabilitation diagnosis (i.e., assigned to a rehabilitation AP-DRG classification) at acute care hospitals and freestanding rehabilitation hospitals including distinct part units;

     (ii) Detoxification services--Detoxification claims are identified as all claims from hospital-based detoxification units, and all claims with a detoxification diagnosis (i.e., assigned to a detoxification AP-DRG classification) at acute care hospitals.

     (iii) CUP women program services--Chemically using pregnant (CUP) women program services are identified as any claims with units of service (days) submitted to revenue code 129 in the claim record.

     (b) The department calculates hospital-specific per diem rates for all medicaid services provided by free-standing psychiatric hospitals, and all psychiatric services provided by acute care hospitals, including distinct part units.

     (c) To determine statewide standardized cost per day amounts for rehabilitation, detoxification and CUP women program services, the department uses the estimated costs of the claims identified for each category based on the department's cost finding process for the system. These claims include any statistical outliers. These statewide standardized amounts serve as the basis for calculating per diem rates for each hospital for each service. The department then makes adjustments to the cost amounts for each hospital to factor out differences related to approved medical education programs.

     (i) For each in-state acute care hospital, excluding critical access hospitals (CAHs) and LTAC hospitals, the department estimates operating and capital costs for each of the three specialty services.

     (ii) The department then adjusts these costs to remove the indirect costs associated with approved medical education programs. Medicare publishes separate indirect medical education factors for operating and capital components, so these adjustments are made separately for both of these components. These factors are intended to reflect the indirect costs incurred by hospitals in support of approved graduate medical education programs.

     (A) For hospital-specific operating costs, the department adjusts the labor portion of the hospital-specific operating costs by the most ((currently available)) current hospital-specific medicare wage index established and published by medicare ((that exists)) at the time of the medicaid rebasing; then adds the nonlabor portion to the result; then divides the result by (1.0 plus the most currently available hospital-specific medicare operating indirect medical education factor established by medicare that exists at the time of the medicaid rebasing); then divides that result by the hospital-specific medicaid case-mix index; then

     (B) For hospital-specific capital costs, the department divides hospital-specific capital costs by (1.0 plus the hospital-specific medicare capital indirect medical education factor); then divides the result by the hospital-specific medicaid case-mix; then

     (iii) The department then sums the costs and days for all included hospitals for each service, and calculates each ((services')) service's statewide standardized weighted average cost per day amounts, weighted based on number of days.

     (d) Once the department establishes the statewide standardized amounts, hospital-specific per diem rates for each specialty service are calculated.

     (i) Starting with the statewide standardized operating amount, the department multiplies the labor portion of the amount (((to determine the labor portion, the department used the factor established by medicare multiplied by the statewide operating standardized amount))) by the most ((currently available)) current hospital-specific medicare wage index established and published by medicare ((that exists)) at the time of the medicaid rebasing((, as published by medicare)). (To determine the labor portion, the department uses the factor established by medicare multiplied by the statewide operating standardized amount.) This adjustment is made to reflect wage differences incurred by hospitals in different regions of the state. The department then adds the nonlabor portion to the result.

     (ii) The department-adjusted operating and capital amounts reflect the indirect costs associated with approved teaching programs. The department adjusts for the indirect costs by multiplying the operating and capital amounts by (1.0 plus the most currently available hospital-specific medicare indirect medical education factor in the medicare final rule for the operating and capital components). These adjustments are made only at the time the rate setting calculation takes place during the rebasing process.

     (iii) The department then adds to the operating and capital amounts the hospital-specific direct medical education cost per day (hospital-specific direct medical education cost per day adjusted for hospital-specific case-mix index).

     (iv) Finally, the department adjusts the facility-specific combined operating, capital and medical education cost per day amounts to reflect increases in inflation between the base year and the implementation year using the CMS PPS Input Price Index. For purposes of this adjustment, the department applies the operating index to the operating and direct medical education components of the per diem rate, and the capital-related index to the capital component of the per diem rate.

     (e) Specialty service claims are not eligible for high outlier payments. See WAC 388-550-3700.

     (4) For dates of admission on and after August 1, 2007, the department establishes hospital-specific per diem rates for psychiatric services provided by instate noncritical access hospitals that are free-standing psychiatric hospitals, acute care hospitals with psychiatric distinct part units, or other acute care hospitals.

     (a) The department identifies psychiatric claims for hospitals meeting the criteria in this subsection as all claims from free-standing psychiatric hospitals, and all claims with a psychiatric diagnosis (i.e., assigned to a psychiatric AP-DRG classification) at the acute care hospitals. The department includes all claims from freestanding psychiatric hospitals, regardless of AP-DRG assignment.

     (b) To determine a facility-specific payment rate per day for psychiatric services, the department uses the greater of the estimated costs per diem of the:

     (i) Hospital's inpatient psychiatric claims in the base year dataset; or

     (ii) Statewide average of the estimated costs of the hospital's inpatient psychiatric claims (as described in subsection (4)(a)) in the base year claims including adjustments for regional wage differences and for differences in medical education costs.

     (c) The department calculates average cost per day amounts for each hospital and then makes adjustments to the average cost per day amounts to reflect changes in the indirect medical education factor and hospital-specific wage index between the base year and the implementation year.

     (d) Finally, the department adjusts the hospital-specific combined operating, capital and medical education cost per day amounts to reflect increases in inflation between the base year and the implementation year using the CMS PPS Input Price Index. For purposes of this adjustment, the department applies the operating index to the operating and direct medical education components of the per diem rate, and the capital-related index to the capital component of the per diem rate.

     (5) For dates of admission on and after August 1, 2007, for hospitals not meeting the criteria in subsection (4), the department calculates per diem rates using the same method used for rehabilitation, detoxification and CUP women program payments described in this section, except that the department uses only the psychiatric claims from those facilities identified as qualifying for hospital-specific rates.

     (6) For dates of admission on and after August 1, 2007, for freestanding rehabilitation facilities, the department uses the per diem rate established for rehabilitative services rather than a facility-specific rate.

     (7) For dates of admission on and after August 1, 2007, for claims that are classified into AP-DRG classifications that do not have enough claims volume to establish stable relative weights, and that are not specialty claims as described in this section, the department also uses a per diem rate.

     (a) These types of claims are less homogeneous than the specialty claims described in this section, and the costs of these claims are more variable than the costs of those that are included under the DRG payment method. The department conducts significant analyses to establish per diem rates based on groupings that would distinguish between higher cost per day claims and lower cost per day claims. As part of this analysis, the department analyzes costs per day based on the following criteria for groupings, which are not mutually exclusive:

     (i) Neonatal claims, based on assignment to major diagnostic category (MDC) 15;

     (ii) Burn claims based on assignment to MDC 22;

     (iii) AP-DRG assignments that include primarily medical procedures;

     (iv) AP-DRG assignments that include primarily surgical procedures;

     (v) Cranial procedure claims, based on specific cranial procedure AP-DRG classifications, and

     (vi) MDC assignment.

     (b) Based on the analyses of cost per day amounts for each grouping criteria identified in subsection (7)(a), the department identified four nonspecialty service groupings appropriate for establishing per diem payments. These are:

     (i) Neonatal claims, based on assignment to MDC 15;

     (ii) Burn claims based on assignment to MDC 22;

     (iii) AP-DRG assignments that include primarily medical procedures, excluding any neonatal or burn classifications identified in this subsection; and

     (iv) AP-DRG assignments that include primarily surgical procedures, excluding any neonatal or burn classifications identified in this subsection.

     (c) For each service group, except for burn cases, the department calculates a per diem rate for each hospital based on the aggregate statewide weighted average cost per day for the service after adjusting costs for regional wage differences and differences in graduate medical education program costs. ((Unstable burn claim)) For burn cases, per diem rates are based on the average operating and capital cost per day ((of unstable burn claims at)) for Harborview Medical Center, which ((treats)) had the vast majority of burn cases in the state.

     (d) The per diem calculations are based on the estimated costs of the claims for each service group in the base year, including both fee-for-service and healthy options claims data. After determining the statewide weighted average cost per day after these adjustments, the department calculates the per diem rate for each hospital for each service group by adjusting the statewide weighted average cost per day amount for each hospital based on its hospital-specific wage index and medical education program costs.

     (e) Because of the variability of the cost of claims in unstable AP-DRG classifications, the department developed an outlier policy for these per diem payments, similar to the outlier methodology recommended for the DRG payment method.

     (f) Claims that are not in the specialty service groupings indicated in subsection (3)(a) and (b), may qualify for a high outlier payment if the claim qualifies under the high outlier criteria. See WAC 388-550-3700.

     (8) For dates of admission on and after August 1, 2007, for inpatient chronic pain services, the department establishes per diem rates based on allowed charges data that the department obtains from the hospital. The department determines the hospital per diem rate by identifying costs and dividing the total cost by the number of days associated with the cost.

     (8) The department makes applicable claim payment adjustments for client responsibility, third party liability, medicare, etc., to claim payments)) The department uses the payment methods described in this section to pay bordering city hospitals and critical border hospitals for inpatient and outpatient claims. Bordering city hospitals and critical border hospitals are defined in WAC 388-550-1050.

     (1) Bordering city hospitals--Inpatient hospital claim payment methods.

     (a) For dates of admission before August 1, 2007, under the diagnosis related group (DRG) payment method:

     (i) The department calculates the cost-based conversion factor (CBCF) of a bordering city hospital as defined in WAC 388-550-1050, in accordance with WAC 388-550-3450.

     (ii) For a bordering city hospital with no medicare cost report (Form 2552-96) submitted for the rebasing year, the department assigns the department peer group average conversion factor. This is the average of all final conversion factors of hospitals in that group.

     (b) For dates of admission before August 1, 2007, under the ratio of costs-to-charges (RCC) payment method:

     (i) The department calculates the RCC in accordance with WAC 388-550-4500.

     (ii) For a bordering city hospital with no medicare cost report (Form 2552-96) submitted for the rebasing year, the department bases the RCC on the Washington instate average RCC.

     (c) For dates of admission on and after August 1, 2007:

     (i) The department calculates the payment for allowed covered charges related to medically necessary services, using the lowest of the instate inpatient hospital rates without graduate medical education (GME) (excluding DWCC rates that are paid to instate critical access hospitals) for the DRG conversion factor, the per diem, per case, and RCC payment methods; and

     (ii) The department pays the lesser of the:

     (A) Billed charges; or

     (B) Calculated payment amount.

     (2) Bordering city hospitals--Outpatient hospital claim payment methods for allowed covered charges related to medically necessary services.

     (a) For bordering city hospitals paid according to the outpatient prospective payment system (OPPS), refer to WAC 388-550-7000 through 388-550-7600. The department uses the following types of payment methods used in OPPS:

     (i) Ambulatory payment classification (APC) method (the primary payment method for OPPS) (WAC 388-55-7200):

     (A) Before August 1, 2007, the department determines the OPPS conversion factor using the methods described in WAC 388-550-7500.

     (B) On and after August 1, 2007, the department pays using the lowest instate OPPS conversion factor.

     (ii) OPPS maximum allowable fee schedule (WAC 388-550-7200).

     (iii) Hospital outpatient RCC rate (WAC 388-550-4500).

     (A) Before August 1, 2007, the department pays the instate average hospital outpatient RCC rate times the allowed covered charges for medically necessary services.

     (B) On and after August 1, 2007, the department pays the lowest instate hospital outpatient RCC rate times the allowed covered charges for medically necessary services.

     (b) For bordering city hospitals exempt from OPPS, the department uses the following payment methods:

     (i) Outpatient maximum allowable fee schedule (WAC 388-550-6000); and

     (ii) Hospital outpatient RCC rate (WAC 388-550-4500).

     (c) When the RCC payment method described in WAC 388-550-4500 is used to pay for outpatient services provided:

     (i) Before August 1, 2007, the department pays the instate average hospital outpatient RCC rate times the allowed covered charges for medically necessary services.

     (ii) On and after August 1, 2007, the department pays the lowest instate hospital outpatient RCC rate times the allowed covered charges for medically necessary services.

     (d) When the maximum allowable fee schedule method is used to pay for outpatient services provided, the department pays the lesser of the:

     (i) Billed charges; or

     (ii) Calculated payment amount.

     (3) Designated critical border hospitals.

     (a) Beginning August 1, 2007, the department designated certain qualifying hospitals located out-of-state as critical border hospitals. A designated critical border hospital must:

     (i) Be a bordering city hospital as described in WAC 388-550-1050; and

     (ii) Have submitted at least ten percent of the total nonemergency inpatient hospital claims that have been paid to bordering city hospitals for the prior state fiscal year (SFY) for clients eligible for Washington state medicaid and state-administered programs. Nonemergency inpatient hospital claims are defined as those that do not include emergency room charges (revenue code 045X series).

     (b) The department analyzes bordering city hospitals' base period claims data during the rebasing process, and annually thereafter, to determine if a bordering city hospital qualifies or continues to qualify as a critical border hospital.

     (4) Critical border hospitals--Inpatient hospital claim payment methods. The department pays inpatient critical border hospital claims with dates of services on and after August 1, 2007, as follows:

     (a) The inpatient payment rates used to calculate payments to critical border hospitals are prospective payment rates. The rates are not used to pay for claims with dates of admission before the hospital qualified as a critical border hospital.

     (b) The department pays inpatient critical border hospital claims using the same payment methods and rates as for instate hospital claims, including DRG, RCC, per diem, outliers, and per case rate, subject to the following:

     (i) Inpatient payment rates used to pay critical border university hospitals for inpatient hospital claims cannot exceed the highest corresponding inpatient payment rate for an instate university hospital;

     (ii) Inpatient payment rates used to pay critical border Level 1 trauma centers for inpatient hospital claims cannot exceed the highest corresponding inpatient payment rate for an instate Level 1 trauma center; and

     (iii) Inpatient payment rates used to pay critical border hospitals not listed in (A) and (B) of this subsection for inpatient hospital claims cannot exceed the highest corresponding instate inpatient payment rate for instate hospitals that are not designated as:

     (A) Critical access hospitals (CAHs);

     (B) University hospitals; or

     (C) Level 1 trauma centers.

     (5) Critical border hospitals--Outpatient hospital claim payment methods. The department pays outpatient critical border hospital claims with dates of services on and after August 1, 2007, using the same payment methods as for instate outpatient hospital claims, including the APC method using the hospital's OPPS conversion factor, maximum allowable fee schedule method, and the hospital outpatient RCC rate method (refer to WAC 388-550-7000 through 388-550-7600 and WAC 388-550-4500), subject to the following:

     (a) Outpatient rates used to pay critical border university hospitals for outpatient claims cannot exceed the highest corresponding rate for an instate university hospital.

     (b) Outpatient rates used to pay critical border Level 1 trauma centers for outpatient claims cannot exceed the highest corresponding rate for an instate Level 1 trauma center.

     (c) Outpatient rates used to pay the critical border hospitals not listed in (i) and (ii) of this subsection for outpatient claims cannot exceed the highest corresponding rate for instate hospitals that are not designated as:

     (i) Critical access hospitals (CAH);

     (ii) University hospitals; or

     (iii) Level 1 trauma centers.

     (6) Critical border hospitals are eligible to receive payment for graduate medical education (GME). All other bordering city hospitals are not eligible to receive payment for GME.

     (7) The department makes:

     (a) Claim payment adjustments, including but not limited to, third party liability, medicare, and client responsibility; and

     (b) Other necessary adjustments as directed by the legislature (e.g., rate rebasing and other changes).
