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.

All imported releases, checksums, and import reports are listed on the data sources page.

• A HCPCS code being valid does not mean Medicare or any other payer covers the item; coverage is determined by the payer and the MAC.
• CMS publishes NDC–HCPCS crosswalks to support ASP-based Part B payment; they are not a comprehensive list of NDCs that may be billed with this code.
• Payment limits are national Medicare Part B limits per billing unit, before deductible, coinsurance, and sequestration. They are not commercial payer rates.
• Hospital outpatient (OPPS) payment rates and status indicators are not included in this release.
• MUE values are the published CMS NCCI limits for Medicare fee-for-service claims; other payers may apply their own unit limits, and CMS keeps some MUE values confidential.
