Immediately for Michigan practices: 1) Ensure all PAs providing services to Medicaid patients are enrolled in CHAMPS as Rendering/Servicing-Only providers with Individual NPIs. 2) Update billing system to require PA NPI in Rendering Provider field and supervising physician NPI in Supervising Provider field on all PA claims. 3) Verify all PAs have valid practice agreements with Medicaid-enrolled physicians and maintain copies on-site. 4) Update PA enrollment to associate with participating physician NPIs in CHAMPS.
