Contact

National Medicare Authority serves as a public reference resource on Medicare eligibility, enrollment, coverage, costs, and rights. This page explains how to reach the editorial office, what geographic scope the site covers, and what information to include when submitting a question or correction request. Understanding the fastest path to a response helps avoid delays, especially when Medicare enrollment deadlines are at stake.

Additional contact options

For time-sensitive Medicare questions — particularly those involving enrollment periods, late-enrollment penalties, or coverage decisions — official federal channels provide the most authoritative and actionable responses.

Medicare's official helpline operates 24 hours a day, 7 days a week and is reachable at 1-800-MEDICARE (1-800-633-4227). TTY users can call 1-877-486-2048. The Medicare.gov portal also hosts a live chat function and a personal plan comparison tool.

Social Security Administration handles Medicare enrollment for most beneficiaries. The SSA can be reached at 1-800-772-1213 or through ssa.gov. Local field offices accept walk-in appointments for enrollment assistance.

State Health Insurance Assistance Programs (SHIPs) provide free, unbiased Medicare counseling through trained counselors in every U.S. state and territory. SHIPs do not sell insurance products. The SHIP National Technical Assistance Center maintains a locator at shiphelp.org.

Medicare Advantage and Part D plan sponsors must be contacted directly for plan-specific benefit questions, prior authorization requests, and claims disputes. Plan contact numbers appear on the back of every membership card.

How to reach this office

The National Medicare Authority editorial office accepts written inquiries related to site content — including factual corrections, clarification requests on published information, and questions about the scope of topics covered on the site.

Messages submitted through the site's contact form are reviewed on business days. Responses to general inquiries are typically provided within 3–5 business days. Requests involving factual correction claims receive priority review and may require additional verification time before a response is issued.

This office does not provide:

1. Personalized Medicare plan recommendations
2. Claims adjudication or appeals assistance
3. Legal or financial advice related to Medicare coverage decisions
4. Enrollment processing or plan enrollment confirmations
5. Medical necessity determinations

For any of those needs, the official channels listed in the section above are the appropriate starting point. SHIP counselors, in particular, are equipped to walk beneficiaries through plan comparisons and enrollment paperwork at no cost.

Service area covered

National Medicare Authority covers the federal Medicare program as administered by the Centers for Medicare & Medicaid Services (CMS) across all 50 U.S. states, the District of Columbia, Puerto Rico, Guam, the U.S. Virgin Islands, American Samoa, and the Northern Mariana Islands.

The site's content addresses Original Medicare (Parts A and B), Medicare Advantage (Part C), prescription drug coverage (Part D), and supplemental Medigap policies. State-specific Medicaid rules — which differ across all 50 states and are administered separately from Medicare — fall outside this site's primary scope, though the intersection of Medicare and Medicaid for dual-eligible beneficiaries is addressed in Medicare Low-Income Assistance Programs.

State-level insurance regulations that govern Medigap plan sales, agent licensing, and open enrollment protections vary by jurisdiction and are not comprehensively cataloged here. For state-specific Medigap rules, the relevant state insurance commissioner's office is the authoritative source.

What to include in your message

Clear, specific messages receive faster and more useful responses. The following breakdown identifies what to include depending on the type of inquiry.

For factual correction requests:
1. The exact URL of the page containing the disputed information
2. The specific sentence or figure believed to be incorrect
3. The named public source (statute, CMS publication, or federal register notice) supporting the correction
4. The date the source was published, if available

For content clarification questions:
1. The topic area in question (for example, Medicare Enrollment Periods or Medicare Late Enrollment Penalties)
2. The specific point of confusion
3. Whether the question relates to Original Medicare or a Medicare Advantage or Part D plan

For general site feedback:
1. The page or section the feedback concerns
2. A description of the issue (broken link, formatting error, missing topic)

Messages that omit a specific page reference or describe an issue only in general terms take longer to resolve. Including a CMS publication number, a CFR citation such as 42 CFR Part 422, or a specific plan year narrows the scope of review considerably and accelerates any editorial response.
