[ Filed October 1, 2004, 12:53 p.m. , effective November 1, 2004 ]


Purpose: (Part 1 of 2) The new rules improve the area of outpatient hospital expenditures, by implementing a new Medicaid payment method for outpatient hospital services provided to Medicaid clients. The outpatient prospective payment system (OPPS) uses claims and cost data to calculate reimbursement to hospitals for the facility component of outpatient services, and uses ambulatory payment classifications (APCs) as the primary basis of payment.

NEW SECTION
WAC 388-550-7000   Outpatient Prospective Payment System (OPPS) -- General.   (1) The medical assistance administration's (MAA's) outpatient prospective payment system (OPPS) uses an ambulatory payment classification (APC) based reimbursement methodology as its primary reimbursement method. MAA is basing its OPPS on the Centers for Medicare and Medicaid Services (CMS) Prospective Payment System for Hospital Outpatient Department Services.

(2) For a complete description of the CMS outpatient hospital prospective payment system, including the assignment of status indicators (SIs), see 42 CFR, Chapter IV, Part 419. The Code of Federal Regulations (CFR) is available from the CFR website and the Government Printing Office, Seattle office. The document is also available for public inspection at the Washington state library (a copy of the document may be obtained upon request, subject to any pertinent charge).

NEW SECTION
WAC 388-550-7050   OPPS -- Definitions.   The following definitions and abbreviations and those found in WAC 388-550-1050 apply to the medical assistance administration's (MAA's) outpatient prospective payment system (OPPS):

"Alternative outpatient payment" means a payment calculated using a method other than the ambulatory payment classification (APC) method, such as the outpatient hospital rate or the fee schedule.

"Ambulatory payment classification (APC)" means a grouping that categorizes outpatient visits according to the clinical characteristics, the typical resource use, and the costs associated with the diagnoses and the procedures performed.

"Ambulatory payment classification (APC) weight" means the relative value assigned to each APC.

"Ambulatory payment classification (APC) conversion factor" means a dollar amount that is one of the components of the APC payment calculation.

"Budget target" means the amount of money appropriated by the legislature or through MAA's budget process to pay for a specific group of services, including anticipated caseload changes or vendor rate increases.

"Budget target adjustor" means the MAA specific multiplier applied to all payable ambulatory payment classifications (APCs) to allow MAA to reach and not exceed the established budget target.

"Discount factor" means the percentage applied to additional significant procedures when a claim has multiple significant procedures or when the same procedure is performed multiple times on the same day. Not all significant procedures are subject to a discount factor.

"Medical visit" means diagnostic, therapeutic, or consultative services provided to a client by a healthcare professional in an outpatient setting.

"Modifier" means a two-digit alphabetic and/or numeric identifier that is added to the procedure code to indicate the type of service performed. The modifier provides the means by which the reporting hospital can describe or indicate that a performed service or procedure has been altered by some specific circumstance but not changed in its definition or code. The modifier can affect payment or be used for information only. Modifiers are listed in fee schedules.

"Observation services" means services furnished by a hospital on the hospital's premises, including use of a bed and periodic monitoring by hospital staff, which are reasonable and necessary to evaluate an outpatient's condition or determine the need for possible admission to the hospital as an inpatient.

"Outpatient code editor (OCE)" means a software program published by 3M Health Information Systems that MAA uses for classifying and editing claims in ambulatory payment classification (APC) based OPPS.

"Outpatient prospective payment system (OPPS)" means the payment system used by MAA to calculate reimbursement to hospitals for the facility component of outpatient services. This system uses ambulatory payment classifications (APCs) as the primary basis of payment.

"Pass-throughs" means certain drugs, devices, and biologicals, as identified by Centers for Medicare and Medicaid Services (CMS), for which providers are entitled to additional separate payment until the drugs, devices, or biologicals are assigned their own ambulatory payment classification (APC).

"Significant procedure" means a procedure, therapy, or service provided to a client that constitutes the primary reason for the visit to the healthcare professional.

"Status indicator (SI)" means a one-digit identifier assigned to each service by the outpatient code editor (OCE) software.

"SI" see "status indicator."

WAC 388-550-7200   OPPS -- Payment method.   (1) This section describes the payment methods the medical assistance administration (MAA) uses to pay for covered outpatient hospital services provided by hospitals not exempted from the outpatient prospective payment system (OPPS).

AMBULATORY PAYMENT CLASSIFICATION (APC) METHOD

(2) MAA uses the APC method when the Centers for Medicare and Medicaid Services (CMS) has established either an APC weight or a national payment rate to pay for covered:

(a) Medical visits;

(b) Significant procedures that are not subject to multiple procedure discounting;

(c) Significant procedures that are subject to multiple procedure discounting;

(d) Nonpass-through drugs or devices;

(e) Observation services; and

(f) Ancillary services.

OPPS MAXIMUM ALLOWABLE FEE SCHEDULE

(3) MAA uses the OPPS fee schedule published in the OPPS section of MAA's billing instructions to pay for covered:

(a) Services that are exempted from the APC payment methodology or services for which there are no established weight(s);

(b) Procedures that are on the CMS inpatient only list;

(c) Items, codes, and services that are not covered by Medicare;

(d) Corneal tissue acquisition;

(e) Drugs or biologicals that are pass-throughs; and

(f) Devices that are pass-throughs.

HOSPITAL OUTPATIENT RATE

(4) MAA uses the hospital outpatient rate described in WAC 388-550-4500 to pay for the services listed in subsection (3) of this section for which MAA has not established a maximum allowable fee.

[]


NEW SECTION
WAC 388-550-7300   OPPS -- Payment limitations.   (1) The medical assistance administration (MAA) limits payment for covered outpatient hospital services to the current published maximum allowable units of services listed in the outpatient prospective payment system (OPPS) fee schedule and published in the OPPS section of MAA's hospital billing instructions, subject to the following:

(a) When a unit limit for services is not stated in the OPPS fee schedule, MAA pays for services according to the program's unit limits stated in applicable WAC and published issuances.

(b) Because multiple units for services may be factored into the ambulatory payment classification (APC) weight, MAA pays for services according to the unit limit stated in the OPPS fee schedule when the limit is not the same as the program's unit limit stated in applicable WAC and published issuances.

(2) MAA does not pay separately for covered services that are packaged into the APC rates. These services are paid through the APC rates.

[]


NEW SECTION
WAC 388-550-7400   OPPS APC relative weights.   The medical assistance administration (MAA) uses the ambulatory payment classification (APC) relative weights established by the Centers for Medicare and Medicaid Services (CMS). MAA updates the APC relative weights at least quarterly in conjunction with the outpatient code editor (OCE) updates.

[]


NEW SECTION
WAC 388-550-7500   OPPS APC conversion factor.   The medical assistance administration (MAA) uses the ambulatory payment classification (APC) conversion factors established by the Centers for Medicare and Medicaid Services (CMS) and in effect on November 1, 2004, as MAA's initial APC conversion factors. MAA updates its APC conversion factors at least biannually.

[]


NEW SECTION
WAC 388-550-7600   OPPS payment calculation.   (1) The medical assistance administration (MAA) follows the discounting and modifier policies of the Centers for Medicare and Medicaid Services (CMS). MAA calculates the ambulatory payment classification (APC) payment as follows:

APC payment=

APC relative weight x APC conversion factor x

Discount factor (if applicable) x Units of service (if applicable) x

Budget target adjustor

(2) The total OPPS claim payment is the sum of the APC payments plus the sum of the lesser of the billed charge or allowed charge for each non-APC service.
