WSR 10-24-021



(Medicaid Purchasing Administration)

[ Filed November 19, 2010, 1:30 p.m. , effective December 20, 2010 ]

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

Purpose: This revision is necessary to update and clarify wording under subsection (3) of this section, specifically the word "percentage" should be "maximum allowable cost."

The rule change clarifies that the department may set "estimated acquisition cost (EAC)" payment rates for certain specified drugs or drug categories, at a maximum cost, rather than as a percentage discount off the reference price. This will allow the department to avoid excessive programming costs associated with setting unique percentage rates on specified drugs. The new wording does not change the prerogative of the department to pay lower EAC rates when appropriate.

Citation of Existing Rules Affected by this Order: Amending WAC 388-530-8000.

Statutory Authority for Adoption: RCW 74.04.050 and 74.08.090.
