The Affordable Care Act requires physicians, or other eligible non-physician practitioners (NPPs), to enroll in the Medicare Program to order/refer items or services for Medicare beneficiaries. This includes those physicians and other eligible NPPs who do not and will not send claims to a Medicare Administrative Contractor (MAC) for their services. The Centers for Medicare & Medicaid Services (CMS) permits such physicians and other eligible NPPs to enroll for the sole purpose of ordering/referring items or services for Medicare beneficiaries.
