National Coverage Determination (NCD)

National Coverage Determination (NCD) refers to official policy decisions made by the Centers for Medicare & Medicaid Services (CMS) regarding the coverage of specific medical services or procedures under the Medicare program. NCDs establish whether Medicare will cover a particular service, item, or treatment based on clinical evidence, medical necessity, and cost-effectiveness. These determinations provide guidance to Medicare beneficiaries, healthcare providers, and insurers regarding the scope of covered services and the criteria for reimbursement.
