Professionally Administered Medication - Community Health Plan of Washington - Medicare Advantage

Prior Authorization for Professionally Administered Medication

The professionally administered drugs listed below require prior authorization. For medications which are listed as requiring prior authorization, CHPW uses national coverage determinations (NCDs) and local coverage determinations (LCDs) when available. NCDs and LCDs are established by the Centers for Medicare and Medicare Services (CMS) and are accessible on the CMS website or through Noridian, Washington’s Medicare Fee-for-Service contractor. If CMS criteria is not available, MCG guidelines or CHPW Clinical Coverage Criteria will be used to determine medical necessity. For self-administered drugs requiring prior authorization, please contact Express Scripts at 1-844-605-8168 or use to start the prior authorization process.
