Derived calculation “Derived $ / NDC” = billable units per NDC × the current payment limit. It is arithmetic for orientation, not a payment amount.

• Coverage documents for A9579 NCDs, LCDs, and Billing & Coding articles in the CMS Medicare Coverage Database that mention “A9579”. Covered diagnosis codes are listed in the articles.

• Find your Medicare contractor (MAC) A/B and DME MAC jurisdictions by state — local coverage and prior-authorization rules come from your MAC.
• CMS discarded drug (JW/JZ) guidance When the JW and JZ modifiers are required for drugs from single-dose containers.
• NCCI Medically Unlikely Edits CMS MUE tables and quarterly changes for practitioner, outpatient hospital, and DME claims.

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.

• Not otherwise classified (NOC/NOS) code on the CMS NOC code list. NOC codes are used when no specific code describes a product; claims commonly require additional information such as the drug name, NDC, dosage, and route. CodeRx never assigns a product to a specific NOC code unless a CMS file supports it.
• 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.
