What is a National Coverage Determination (NCD)?

• A. CMS policy that specifies whether a service is covered nationally and under what conditions.
• B. A determination made by individual hospitals about coverage.
• C. A local rule about billing rates only.
• D. A guideline for pharmaceutical pricing.

Answer: (A)

A National Coverage Determination is a policy issued by CMS that decides whether Medicare will cover a specific medical service nationwide, and it specifies the conditions under which it is covered (such as indications, patient populations, settings, and medical necessity). This creates a uniform standard across the country so providers and beneficiaries know when Medicare will pay for that service. Local Coverage Determinations are made by regional Medicare contractors and can vary by region, applying only where the LCD is in effect. A NCD focuses on coverage decisions, not payment amounts or pricing, which are handled separately. In short, it sets national coverage criteria for Medicare for a service, ensuring nationwide consistency in what is paid for.
