Final answer:
Non-billable RHC services for Medicare beneficiaries include those provided by private hospitals, except when the hospital operates the RHC. Services must meet specific Medicare guidelines to be billable under RHC.
Step-by-step explanation:
A service that is not billable as a Rural Health Clinic (RHC) service for a Medicare beneficiary includes services provided by a private hospital, unless the private hospital operates the RHC. This is because RHC services are typically associated with nonprofit health organizations or governmental agencies such as Health and Social Services, which meet specific criteria to be designated as RHCs. Services provided outside of these entities, or that do not meet Medicare's specific guidelines for RHC services, are generally not billable under the RHC payment method.
