How to Contact Medicare: Phone Numbers, Hours, and Online Options

Getting a human at Medicare on the phone can take patience, and navigating the automated menu system isn't intuitive. But there are times you genuinely need to speak with someone — to dispute a claim, check enrollment status, report fraud, or get a straight answer to a question the website can't resolve.

This article lists every way to contact Medicare, the fastest methods for each type of question, and what to have ready before you call — especially if you're calling on behalf of a parent.

The main Medicare phone number

1-800-MEDICARE (1-800-633-4227)

• Hours: 24 hours a day, 7 days a week
• TTY (hearing impaired): 1-877-486-2048
• Languages: English and Spanish. For other languages, the representative can access interpreter services.

This is the general Medicare helpline run by CMS. The automated system will ask you to enter the beneficiary's Medicare number or Social Security number to route your call. You can press 0 or say "representative" to reach a person, though you'll likely go through a brief menu first.

What you can do through 1-800-MEDICARE

• Check enrollment status (Part A, Part B, Part D, Medicare Advantage)
• Ask questions about coverage and benefits
• Get information about Medicare plans in your parent's area
• Report suspected Medicare fraud or billing errors
• Request a replacement Medicare card
• Get help with Medicare Summary Notices (MSNs) or bills
• File complaints about providers, plans, or services
• Check the status of a claim

Tips for shorter wait times

• Call early in the morning — the first hour after the phone lines open in your time zone tends to have the shortest wait
• Avoid Mondays and the first week of the month — call volumes spike when people receive new bills or statements
• Avoid October-December — the Annual Enrollment Period creates the highest call volumes of the year
• Try late evening or weekend calls — the line is 24/7, and off-peak hours often have shorter waits
• Have the Medicare number ready — the automated system processes calls faster when it can identify the beneficiary immediately

Calling on behalf of a parent

Medicare has privacy protections that restrict who can access a beneficiary's information. If you're calling about your parent's Medicare:

If your parent is present: Put the call on speaker. Your parent can verbally authorize the representative to speak with you for that call. The rep may ask your parent to confirm their name, date of birth, and Medicare number first.

If your parent is not present: You'll need one of these:

• Medicare Authorized Representative — your parent has filed Form CMS-10106 designating you as their representative
• Power of Attorney — a legal POA that covers healthcare or government benefit decisions. Note that Medicare has its own rules about what documentation it accepts — a general POA may not be sufficient
• Representative Payee — if you're your parent's Social Security representative payee

Without one of these, the representative can provide general Medicare information but cannot discuss your parent's specific claims, enrollment, or benefits.

If this is a recurring need (and if you're managing a parent's Medicare, it will be), filing the CMS-10106 authorized representative form is worth doing proactively. It saves the back-and-forth on every future call.

Online: Medicare.gov account

For many routine tasks, the Medicare.gov website is faster than calling.

Setting up an account

Your parent can create an account at Medicare.gov using their Medicare number. The account requires identity verification through Login.gov or ID.me — which can be a hurdle for some elderly users (the identity verification process involves uploading a photo ID and taking a selfie, or doing a video call with a verification agent).

If your parent struggles with the setup, the ID.me video call option allows a human agent to walk them through the verification process. Some families find it easier to help their parent set up the account on a computer or tablet where they can assist with the camera and upload steps.

What you can do online

• View and print the Medicare card — including the Medicare number
• Check claims and coverage — see what's been billed and what Medicare paid
• Compare plans — use the Plan Finder tool
• Check enrollment status — confirm Part A, Part B, and plan enrollment dates
• Review Medicare Summary Notices — available online before the paper version arrives by mail
• Manage Part D plan enrollment — enroll in or switch drug plans

Accessing the account for your parent

If you're managing your parent's Medicare online, you'll typically need to log in using their credentials. Medicare.gov doesn't have a formal "delegate access" feature like some medical portals. In practice, many families help their parent create the account and then manage it with the parent's login information.

By mail

For some matters, you may need to send documents by mail. Relevant addresses:

Medicare general inquiries and claims

Most claims are handled by Medicare Administrative Contractors (MACs) that vary by region. To find the correct MAC and mailing address for your parent's area, call 1-800-MEDICARE or visit cms.gov and search for "Medicare Administrative Contractors."

Social Security (for enrollment and premium issues)

Since Part B enrollment and premium questions are handled by Social Security:

Social Security Administration Office of Earnings Operations P.O. Box 33026 Baltimore, MD 21290-3026

Or visit your local Social Security office — find the nearest one at ssa.gov/locator.

Reporting fraud

Office of the Inspector General Department of Health and Human Services Attn: OIG HOTLINE P.O. Box 23489 Washington, D.C. 20026

Or call the fraud hotline: 1-800-HHS-TIPS (1-800-447-8477)

Other useful numbers

For Medicare Advantage or Part D plan issues

If the issue is with a specific Medicare Advantage or Part D plan (claims, network, formulary, authorization), call the plan directly first. The plan's member services number is on the plan's insurance card and in plan documents. If the plan doesn't resolve the issue, then escalate to 1-800-MEDICARE.

When to call vs. when to go online

Call when:

• You need to dispute a specific claim or bill
• Your parent received a confusing Medicare Summary Notice
• You suspect fraud or billing errors
• You need help with a complex enrollment situation (employer coverage coordination, disability, etc.)
• The online account isn't working or can't resolve your issue

Go online when:

• You want to check enrollment status or view the Medicare card
• You're comparing plans during an enrollment period
• You want to review recent claims
• You need to look up a provider

Visit in person when:

• You're filing a new enrollment application with complex circumstances
