  • Are you wondering who to contact about Medicare? This guide explains whether to call the 1-800-MEDICARE phone number or the Social Security Administration.

When you have questions about your Medicare coverage, your first instinct may be to call the 1-800-MEDICARE phone number. However, Medicare is a complex health care program delivered by a number of partners, including the Social Security Administration, state agencies and private insurance companies.

This guide summarizes the best ways to get answers about your health care coverage to save you time and frustration. Read on for common questions about Medicare and whether you should call the Medicare phone number, visit the Medicare website or contact another organization.

If you're looking for a Medicare Advantage (Medicare Part C) plan that can take the place of your Original Medicare coverage (Parts A and B) and may offer extra benefits like prescription drug coverage, dental, vision, hearing and more, you can compare plans online using a Medicare Plan Finder tool or by calling to speak with a licensed insurance agent.

What Is the Medicare Phone Number?

Medicare can be reached by calling:

  • 1-800-MEDICARE or 1-800-633-4227
  • TTY: 1-877-486-2048

Common Reasons to Call Medicare

You can speak with customer service representatives at Medicare to ask general questions about the health plan or specific questions about your Original Medicare coverage and claims. Callers often have questions about: 

  • Premiums
  • Deductibles, coverage and benefits
  • Eligible preventive screenings
  • The status of a Medicare claim
  • Denied Medicare claims
  • Medicare claim calculations
  • Claim appeals
  • Fraud

Questions related to Medicare Advantage, prescription drug plans and Medigap policies must be directed to your private insurance carrier. You can find their contact information on your plan membership card or materials. Medicaid inquiries are handled by your state agency.

What to Have Ready Before You Call

Your Medicare Number

When you call 1-800-MEDICARE, you're asked to enter your Medicare plan number into the automated system. Be sure to have your Medicare card or number ready at the start of the call.

Claim Information 

If you're inquiring about an Original Medicare claim, you should be prepared with:

  • Your Medicare Summary Notice, if available
  • The name of the doctor or health care provider that you visited
  • The type of service or medical equipment you purchased
  • The date you received the services
  • The amounts of any copayments or cost-sharing that you paid

The 1-800-MEDICARE phone number can only help with Original Medicare claims.

Authorizing Others to Speak to Medicare On Your Behalf

If you need someone to speak to Medicare for you, you must give written permission. Once this authorization is received by Medicare, a customer service agent can discuss your personal health information with another person.

You can download the authorization form from the Medicare website.
