Key takeaways

  • Original Medicare (Parts A and B) covers all 50 states, the District of Columbia, and major U.S. territories.
  • Most healthcare professionals accept Original Medicare, and when moving to a new state, individuals generally maintain their coverage provided they report their address change to the SSA.
  • While traveling abroad, Medicare may not cover healthcare costs, but exceptions exist for services on ships within U.S. territorial waters, medical emergencies requiring immediate attention, or when a person lives closer to a non-U.S. hospital.

Whether traveling or temporarily residing in another state, people may wonder if they can use their Medicare benefits while away from home.

Those with Original Medicare (parts A and B) can generally use their coverage anywhere in the United States. However, Medicare Advantage (Part C) plans may have limitations on where a person can receive covered care.

Glossary of Medicare terms

  • Out-of-pocket cost: This is the amount a person must pay for care when Medicare does not pay the total amount or offer coverage. Costs can include deductibles, coinsurance, copayments, and premiums.

  • Deductible: This is an annual amount a person must spend out of pocket within a certain period before Medicare starts to fund their treatments.
  • Coinsurance: This is the percentage of treatment costs that a person must self-fund. For Medicare Part B, coinsurance is 20%.
  • Copayment: This is a fixed dollar amount a person with insurance pays when receiving certain treatments. For Medicare, this usually applies to prescription drugs.

  • Puerto Rico
  • the Virgin Islands
  • Guam
  • American Samoa
  • the Northern Mariana Islands

Most U.S. healthcare professionals accept Original Medicare.

If a person decides to move to another state, they need to report their change of address to the Social Security Administration (SSA) by:

People will not lose their Original Medicare coverage when moving to another state as long as their new doctor, healthcare facility, or other provider accepts Medicare.

Plans with private insurance companies

Medicare-approved private insurance companies administer:

If a private insurance company administers a person’s Medicare plan, they will need to contact the plan provider directly to change their address.

Most companies provide an option for contacting them online, by phone, or by mail.

Not all plans are available from all insurers in all states or counties. Upon moving, an individual may need to change their insurance provider, plan, or both, which could bring different benefits and rules.

If a person travels outside the United States or its territories and requires healthcare, Medicare may not provide coverage.

However, there are a few exceptions, and services that could be eligible for coverage include:

  • inpatient hospital care
  • doctor visits
  • ambulance services

On board a ship

Medicare Part B will cover health services provided while a person is on board a ship currently in U.S. territorial waters and adjoining U.S. land areas.

If a ship is over 6 hours away from a U.S. port, Medicare may not pay for medical services.

Medical emergency

If a medical emergency requires immediate attention while a person is in the United States, but a foreign hospital is closer than a U.S. hospital to treat the medical condition, coverage is usually available.

Medical emergency when traveling from Alaska

Services typically receive coverage if a person is traveling between Alaska and another U.S. state when a medical emergency occurs and a Canadian hospital is closer than the nearest U.S. hospital.

Non-U.S. hospital closer to residence

When residing in the United States and the nearest U.S. hospital is further from a person’s home than the closest non-U.S. hospital, coverage may be approved regardless of whether a medical emergency takes place.

If a member purchases prescription drugs outside the United States, Medicare usually will not cover the cost.

Medigap plans may offer coverage for medical services or supplies a person receives outside the United States or when traveling.

If a person has a Medigap plan, their coverage may include emergency non-U.S. medical care when traveling, which is applicable if the medical incident occurs during the first 60 days of the trip and if Original Medicare does not cover the care.

It may also include 80% of costs after a person has met the yearly deductible. The 80% coverage relates to some kinds of necessary emergency care outside the United States.

Currently, most Medigap plans have non-U.S. emergency coverage, which has a lifetime limit of $50,000.

People who already have Original Medicare insurance can keep it while living outside the United States. However, this typically does not cover medical care they receive outside the country.

If they qualify for Part A coverage, they can contact their nearest U.S. Social Security office, U.S. Consulate, or U.S. Embassy to enroll.

If an eligible person lives outside the United States and wants to enroll in Medicare Part B, they can only do so in the month they return to the United States. Depending on their situation, they may pay higher premiums.

Late enrollment penalties may apply if an individual does not enroll in Part B within 3 months of returning to the United States.
