Derived calculation “Derived $ / NDC” = billable units per NDC × the current payment limit. It is arithmetic for orientation, not a payment amount.
Medicare coverage is set nationally (NCDs) and by each Medicare Administrative Contractor (LCDs and Billing & Coding articles). These links open the official documents.
Verification neededCodeRx links to coverage documents instead of copying them: CMS distributes their code lists under AMA, ADA, and AHA license terms that limit reuse. Medicare Advantage, Medicaid, and commercial plans set their own coverage and prior-authorization rules.
