How does HRSA enforce 340B re-registration after hospital mergers in 2026?

In 2026, HRSA’s Office of Pharmacy Affairs requires hospitals and clinics involved in mergers to revalidate 340B eligibility within 30 days of the legal transaction. Failure to meet this deadline can result in removal from the 340B database, loss of contract pharmacy claims, and audit findings tied to incomplete or delayed re-registration documentation.
