Is There a Medicare Toll-Free Number I Can Call in the USA? (2026)

Quick Answer

Yes. Medicare's official toll-free number is 1-800-MEDICARE (1-800-633-4227), staffed 24 hours a day, seven days a week except some federal holidays. TTY users can call 1-877-486-2048. The line answers questions about Original Medicare, Medicare Part A, Medicare Part B, Medicare Part D, Medicare Advantage, and Medigap, plus claims, enrollment, and fraud reports. For Part B enrollment or a replacement card, call Social Security at 1-800-772-1213 instead.

What 1-800-MEDICARE Can Help You With

1-800-MEDICARE connects callers to a national customer service team that handles the full range of everyday Medicare questions. Representatives can explain what Original Medicare covers under Part A (hospital insurance) and Part B (medical insurance), walk through Medicare Advantage plan options for a specific ZIP code, and compare Medicare Part D drug plan costs before the Annual Enrollment Period. They can also check the status of a claim, request a replacement Medicare card, update a mailing address, and file a formal complaint about a provider or plan.

Callers weighing Medicare Advantage against a Medigap supplemental policy can ask general questions about how each type of plan works, though 1-800-MEDICARE representatives cannot recommend a specific private plan; that comparison work is better suited to a licensed agent or a free SHIP counselor covered below. The automated phone system also lets callers request Medicare & You handbooks and other mailed publications without waiting for a live representative.

• Check Original Medicare Part A and Part B claim status
• Compare Medicare Advantage and Medicare Part D plan options by ZIP code
• Request a replacement Medicare card
• File a complaint about a provider, supplier, or plan
• Get general Medigap plan-type explanations, not plan recommendations

When to Call Social Security Instead

Medicare enrollment itself runs through the Social Security Administration, not 1-800-MEDICARE. Call Social Security at 1-800-772-1213 (TTY 1-800-325-0778), Monday through Friday from 8 a.m. to 7 p.m. local time, to sign up for Medicare Part A and Part B during your Initial Enrollment Period, the General Enrollment Period (January 1 to March 31, 2026), or a Special Enrollment Period after losing employer coverage. Social Security also handles Medicare Part B premium questions, Income-Related Monthly Adjustment Amount (IRMAA) appeals, Extra Help applications for Medicare Part D costs, and replacement Social Security or Medicare cards.

If your Medicare eligibility is tied to railroad employment, use the Railroad Retirement Board line at 1-877-772-5772 instead of Social Security; the RRB, not Social Security, manages Medicare enrollment for railroad retirees and their families.

Free Help from Your State SHIP Counselor

Every state runs a State Health Insurance Assistance Program (SHIP) that provides free, unbiased, one-on-one counseling on Medicare choices, funded through the federal Administration for Community Living. A local SHIP counselor can review Original Medicare plus Medigap against Medicare Advantage plans available in your county, check whether your Medicare Part D drug list still matches your prescriptions, and help with income-based assistance programs like Extra Help and Medicare Savings Programs.

Unlike an insurance agent, a SHIP counselor does not sell plans and has no financial stake in your choice. Find your state's SHIP phone number at shiphelp.org, or ask a 1-800-MEDICARE representative to transfer you; Kentucky's SHIP line, for example, is 1-877-293-7447.

Reporting Medicare Fraud or Scam Calls

Medicare fraud costs the program billions of dollars a year in improper billing, and scam callers impersonating Medicare are common, especially during the Annual Enrollment Period (October 15 to December 7, 2026). Report suspected fraud or a scam call directly to 1-800-MEDICARE, or call the Department of Health and Human Services Office of Inspector General fraud hotline at 1-800-447-8477 (1-800-HHS-TIPS), open Monday through Friday, 8 a.m. to 5:30 p.m. Eastern time.

CMS recommends the 4 Rs: Record the caller's information, Resist sharing your Medicare number or Social Security number over the phone, Report the call, and Reduce your risk by hanging up on anyone who calls unsolicited claiming to be from Medicare. Real Medicare representatives never call to ask for your Medicare number, bank details, or a payment to keep your coverage active.

If Your Question Is About ACA Marketplace Coverage

1-800-MEDICARE only handles Medicare, the federal program for people 65 and older or with qualifying disabilities. If your question is about Affordable Care Act marketplace coverage instead, such as whether a plan is ACA-compliant, whether preexisting condition protections apply, or which of the 10 essential health benefits a plan must cover, call the Health Insurance Marketplace call center at 1-800-318-2596 (TTY 1-855-889-4325) instead. Marketplace representatives are a separate team from Medicare customer service and cannot access Medicare claims or enrollment records, so mixing up the two numbers usually means a transfer or a second call.

How to Reach a Live Person Faster in 2026

Hold times on 1-800-MEDICARE climb sharply during the Annual Enrollment Period (October 15 to December 7, 2026) and the Medicare Advantage Open Enrollment Period (January 1 to March 31, 2026). Calling early on a Tuesday, Wednesday, or Thursday morning, outside those windows, typically gets a shorter wait. Before dialing, have your Medicare number, date of birth, and a specific question ready so the automated system routes the call correctly the first time.

• Step 1: Have your Medicare number, ZIP code, and a one-sentence description of your question ready before you call.
• Step 2: Call 1-800-MEDICARE (1-800-633-4227) or start a live chat at medicare.gov/talk-to-someone if you prefer not to wait on hold.
• Step 3: If your question is about enrollment, Part B premiums, or a replacement Social Security card, call 1-800-772-1213 instead.
• Step 4: For plan comparisons or Medicare Savings Program help, ask to be connected with your local SHIP counselor or call the number listed at shiphelp.org.
• Step 5: Save your confirmation number and the representative's name for any request tied to a claim, complaint, or fraud report.
