Merck joins its peers with plan to cut access to discounted drugs for contract pharmacies

Effective Sept. 1, Merck said it will no longer voluntarily honor 340B discounts or chargebacks for contract pharmacies that have not begun to provide 340B claims data, unless the hospital-covered entity lacks its own in-house pharmacy and designates a contract pharmacy of its choice. The move directly counters what HHS stipulated in its letter from May with regard to imposing conditions and requiring claims data.
