Dear Valued Provider, Effective January 1, 2016, PrimeWest Health will transition their Medicaid and Medicare Part D products from Prime Therapeutics to MedImpact. Participating Pharmacies will no longer be able to submit claims to Prime Therapeutics for Medicaid or Medicare Part D Covered Persons for dates of service after 12/31/15 for the following BIN and PCN combinations:

11/13/2015 Dear Pharmacy Network Provider, Beginning January 1, 2016 all claims submitted to PerformRx must be submitted with a valid Prescriber National Prescriber Identifier (NPI) number. This is a result of MACRA Legislation which was passed April 16, 2015. Currently PerformRx accepts claims submitted with only a Drug Enforcement Agency (DEA) identifier for select customers. Beginning January 1, 2016, claims submitted with only a DEA number and identifier will deny at point-of-sale and reject with error 434 (Valid Prescriber Type 1 NPI Required), requiring the pharmacy to submit a valid Prescriber NPI number and qualifier.
