How we source

Every coverage page on Covered. cites primary sources from CMS, Medicare.gov, or the relevant state Medicaid agency. Here's how we decide what to publish — and how to flag something that's out of date.

Where our information comes from

• CMS — Centers for Medicare & Medicaid Services

  Federal coverage rules, NCDs (National Coverage Determinations), LCDs (Local Coverage Determinations), DMEPOS fee schedules, and the Medicare Coverage Database.

• Medicare.gov

  Beneficiary-facing publications, plan finder, and the official 'What Medicare Covers' guides.

• U.S. Congress — Congress.gov

  Bill text and status for federal legislation that affects DME coverage (e.g., S.4070, the Diabetes Foot Health Act).

• State Medicaid agencies

  State-by-state Medicaid coverage rules, prior-authorization forms, and managed care org details. We cite each state directly on its respective page.

• MAC — DME Medicare Administrative Contractors

  DME MACs (Noridian, CGS) publish jurisdiction-specific LCDs and policy articles that govern claim adjudication.

Editorial principles

• ✓Cite primary sources, not other reference sites. If a number is on a CMS document, that's where we link.
• ✓Stamp every page with a 'Last verified' date. We re-verify each page at least quarterly, and immediately when a known rule changes.
• ✓Show our work. Every cost figure links to the CMS document we pulled it from.
• ✓No undisclosed sponsorship. Covered. is independent. We do not sell Medicare Advantage plans, Medigap policies, or DME equipment. The only commercial relationship is referrals to Medicare-enrolled DME suppliers (clearly disclosed).
• ✓Beneficiary first. When CMS rules and supplier interests conflict, we side with the beneficiary.

Found something out of date?

Coverage rules change. If a page is wrong, stale, or missing a recent update, please tell us so we can re-verify and fix it.

Email hello@covered.example.com with the page URL and what changed (or a link to the source). We update within 5 business days for confirmed corrections.
