Effective Date of Rule: Thirty-one days after filing.

     Purpose: Upon order of the governor, the agency reduced its budget expenditures for fiscal year 2011 by 6.3 percent. To achieve the expenditure reduction required under Executive Order 10-04, the agency took the following actions:

•	Effective January 1, 2011, the agency eliminated dental-related services from program benefit packages for clients twenty-one years of age and older, except clients whose care is managed by the division of developmental disabilities, and implemented an emergency oral health benefit for all other adult clients.
•	Effective July 1, 2011, in addition to clients whose care is managed by the division of developmental disabilities, the agency reinstated comprehensive dental coverage for certain clients twenty-one years of age and older, as specified in the proposed rules.
•	Effective October 1, 2011, the agency reduced eligibility for the comprehensive dental benefit for certain clients of the division of developmental disabilities, as specified in the proposed rules.

     Governor Gregoire issued Executive Order 10-04 on September 13, 2010, under the authority of RCW 43.88.110(7). In the executive order, the governor required the health care authority and all other state agencies to reduce their expenditures in state fiscal year 2011 by approximately 6.3 percent. As a consequence of the executive order, funding will no longer be available as of January 1, 2011, for the benefits that are being eliminated as part of these regulatory amendments.

     (3) ((MAA)) The agency reimburses dental general anesthesia services for eligible clients on the basis of base anesthesia units plus time. Payment for dental general anesthesia is calculated as follows:

     (a) Dental procedures are assigned an anesthesia base unit of five;

     (b) Fifteen minutes constitute one unit of time. When a dental procedure requiring dental general anesthesia results in multiple time units and a remainder (less than fifteen minutes), the remainder or fraction is considered as one time unit;

     (c) Time units are added to the anesthesia base unit of five and multiplied by the anesthesia conversion factor;

     (d) The formula for determining payment for dental general anesthesia is: (5.0 base anesthesia units + time units) x conversion factor = payment.

     (4) When billing for anesthesia, the provider must show the actual beginning and ending times on the claim. Anesthesia time begins when the provider starts to physically prepare the client for the induction of anesthesia in the operating room area (or its equivalent), and ends when the provider is no longer in constant attendance (i.e., when the client can be safely placed under postoperative supervision).

     (5) ((MAA)) The agency pays eligible providers listed in WAC ((388-535-1070)) 182-535-1070 for conscious sedation with parenteral and multiple oral agents, or for general anesthesia when the provider meets the criteria in this chapter and other applicable WAC.

     (6) Dental hygienists who have a contract with ((MAA)) the agency are paid at the same rate as dentists who have a contract with ((MAA)) the agency, for services allowed under The Dental Hygienist Practice Act.

     (7) Licensed denturists who have a contract with ((MAA)) the agency are paid at the same rate as dentists who have a contract with ((MAA)) the agency, for providing dentures and partials.

     (8) ((MAA)) The agency makes fee schedule changes whenever the legislature authorizes vendor rate increases or decreases.

     (9) ((MAA)) The agency may adjust maximum allowable fees to reflect changes in services or procedure code descriptions.

     (10) ((MAA)) The agency does not pay separately for chart or record setup, or for completion of reports, forms, or charting. The fees for these services are included in ((MAA's)) the agency's reimbursement for comprehensive oral evaluations or limited oral evaluations.
