Do clinics/departments located within the four walls of a registered 340B hospital have to be registered in the 340B database?

Outpatient clinics/departments within the four walls (i.e., same physical address) of the registered parent 340B hospital do not need to also register into the 340B Program. However, the covered entity remains responsible for showing that those outpatient clinics/departments are listed as reimbursable on the hospital’s most recently filed Medicare cost report, are only using 340B drugs for eligible outpatients, meet all 340B Program requirements, and maintain auditable records. Clinics at an offsite location from the registered parent must separately register on the 340B database, even if they are located within the four walls of that child site. This applies to all registered areas of off-site (from the parent) clinics/hospitals. Every eligible clinic that will purchase or use 340B drugs within such a hospital must register separately as a child site.
