Merck Contract Pharmacy Restrictions

Drug maker Merck extended its restrictions on 340B pricing involving contract pharmacies to community health centers. Beginning May 31st, Merck will no longer voluntarily honor 340B discounts or chargebacks for contract pharmacy transactions, unless the community health center provides 340B claims data for all claims originating from their contract pharmacies. If the community health center lacks its own in-house pharmacy, Merck will allow that health center to designate a single contract pharmacy to receive 340B discounts without requiring the health center to input data to 340B ESP. See here for Merck’s letter to covered entities.
