You can sign up for Medicare on the first day of the month beginning three months before you turn 65 until three months after you turn 65. Thats known as your Initial Enrollment Period (IEP).

Open Enrollment

Medicare health and drug plans can make changes each year—things like cost, coverage, and what providers and pharmacies are in their networks. October 15 to December 7 is when all people with Medicare can change their Medicare health plans and prescription drug coverage for the following year to better meet their needs.

To see if you are eligible, see our Section on Signing Up below.

What is Medicare?

Medicare is a United-States health-insurance program for Americans over the age of 65 or those under 65 with certain disabilities. Its administered by the federal government.

With few exceptions, Medicare will cover members only when theyre in the United States. For example, an exception would be if you lived in the United States but your closest hospital is in Canada or Mexico, Medicare would cover you under those circumstances.

What is Medicaid?

Medicaid is a federal health-insurance program for low-income adults thats administered by the individual states. Eligibility has income restrictions, and vary from state to state. Some people who receive Medicare may also qualify for Medicaid.

What is CMS?

The Centers for Medicare & Medicaid Services (CMS) is a federal agency within the United States Department of Health and Human Services (HHS) that administers the Medicare program, works in partnership with state governments to administer Medicaid and the Children's Health Insurance Program (CHIP), and sets and monitors health-insurance standards for the various programs.

What are Medicare’s components?

Medicare Part A pays for many of your costs when your doctor has admitted you to the hospital (inpatient). It includes doctors, room, meals, treatment, tests, and medications. It also covers care in a skilled nursing facility (not the same as a nursing home), hospice care, and some home health care. 

For most people, there is no premium for Part A.   But if youre not eligible for premium-free Part A, here are the specifics

Medicare Part B generally pays 80% of your doctor and clinician bills in a doctors or therapists office, or when you get treatment in a hospital as an outpatient. Part B pays 80% of what Medicare allows a participating doctor to charge you, not your doctors normal, much higher fee.

Part B has a monthly premium that under most circumstances is deducted from your Social Security payment before you see it show up in your bank account every month. If youre 65, but not yet collecting Social Security benefits, you can still sign up for Medicare, but Medicare will send you a bill for the premiums.   Medicare also has a fairly low annual deductible.

Medicare Part C, aka Medicare Advantage is not really Medicare at all, but private insurance that replaces Medicare for those eligible for Medicare. For additional information click here.

Medicare Part D is also private insurance, but this component covers prescription medications you get at a pharmacy. If your doctor advises you to take aspirin or another pain reliever, for example, that would not be covered as a prescription drug unless its prescribed in a prescription-strength dose. There are other options for prescription coverage that might be better in your situation, especially as an expat. 

Within the United States you might find it more cost effective to purchase prescription medication with one of the coupon systems, such as GoodRx. But you need to do your homework first and check the availability and costs of your drugs, and whether the pharmacy you want to use accepts a particular coupon plan.

As an expat, your country of residence could have a significant impact on what you pay for prescriptions. Many countries have prescription drug prices that are far lower than in the U.S. even if you dont participate in that countrys national health system. So check out your local options and requirements.

Medigap or Medicare supplement insurance is private insurance that you pay for each month directly to an insurance company. Depending on the specific plan, it covers some or all of the costs not covered by Medicare Parts A and B. Supplement policies are designated by letters of the alphabet, and availability depends on the state in which you live. While not every insurance company offers every plan, each Plan A or Plan G for example offered by a company must be identical to every other Plan A or Plan G offered by others; premium prices differ from company to company.

Signing Up


When can I sign up for Medicare?

You can sign up for Medicare on the first day of the month beginning three months before you turn 65 until three months after you turn 65. Thats known as your Initial Enrollment Period (IEP). Signing up after that can incur penalties and coverage restrictions. You can find your exact IEP here: when can I sign up for Medicare?

When does coverage start?

The date your coverage starts depends on which month you sign up during your Initial Enrollment Period. Coverage always starts on the first of the month.

If you qualify for Premium-free Part A:

Your Part A coverage starts the month you turn 65. If your birthday is on the first of the month, coverage starts the month before you turn 65.

Part B (and Premium-Part A if you dont qualify for premium free): Coverage starts based on the month you sign up. This chart will help you determine your start date.

How to sign up when you have a U.S. address

How to sign up when you don’t have a U.S. address

If you dont maintain a U.S. address while living abroad, youll need to contact the Federal Benefits Office at the U.S. Consulate that covers the country where you live for the enrollment forms. You should also contact the Social Security Administration to get a letter stating that youve entered your Initial Enrollment Period.   Documenting your IEP is crucial to avoiding late enrollment and other penalties. So even if youre working with the federal benefits office in your country of residence, also get it in writing from the SSA. 

If you don’t sign up for Medicare Part B during your Initial Enrollment Period

In general, there is a permanent monthly penalty for not signing up for Medicare Part B during your Initial Enrollment Period.

Exemptions to the sign-up penalty

You can only avoid the penalty  if you have other creditable insurance.” This usually means someone who is still working at age 65 and has insurance through their employer or through a spouses employer. Under some circumstances it can also mean health insurance sponsored by a foreign government or foreign employer.   Youll need to get specifics for your own circumstances by contacting Medicare and/or by speaking to the federal benefits people in your country of residence.



Are you covered by Medicare when outside  the USA and its territories?

No. Coverage is only valid for care performed within  the United States, with a few very limited exceptions.
