Get Sick Overseas and Original Medicare Pays Almost Nothing. One Add-On Covers 80%

A 68-year-old retiree flies to Lisbon, slips while stepping off a tram on her third day, and suddenly finds herself facing a major medical bill. Between surgery, hospitalization, and transportation home, the costs quickly climb into the thousands of euros. Her Original Medicare card does what it does at most foreign hospitals: nothing. The bill is hers.

This article is for Medicare beneficiaries who travel outside the United States, even if it’s only an occasional trip. If you are enrolled in a Medicare Advantage plan, different rules may apply, since many plans include limited worldwide emergency coverage. If international travel is not part of your plans, this is one Medicare gap you can safely ignore.

What Original Medicare Actually Pays Abroad

The default answer is simple: almost nothing. Part A and Part B generally do not cover care outside the 50 states, the District of Columbia, Puerto Rico, the U.S. Virgin Islands, Guam, the Northern Mariana Islands, and American Samoa. Part D plans generally do not cover prescriptions filled outside the United States either.

The exceptions are narrow and worth knowing because many retirees assume they are broader than they are. Medicare may cover certain hospital, physician, and ambulance services in a foreign country in three limited situations:

• You are in the United States during a medical emergency, and a foreign hospital is closer than the nearest U.S. hospital that can treat you.
• You are traveling by the most direct route between Alaska and another U.S. state through Canada, without unreasonable delay, and a Canadian hospital is closer during an emergency.
• You live in the United States, and a foreign hospital is closer to your home than the nearest U.S. hospital capable of treating your condition, whether it is an emergency or not.

None of those exceptions help the typical international traveler. A heart attack in Rome, a fall in Tokyo, or a stroke on a cruise ship beyond U.S. waters generally leaves the beneficiary responsible for the bill. For most overseas medical emergencies, Original Medicare provides no meaningful protection.

The One Add-On That Changes the Math

Six standardized Medigap plans include a foreign travel emergency benefit: Plans C, D, F, G, M, and N. Plans C and F are closed to anyone who became Medicare-eligible on or after January 1, 2020, so for most current shoppers the live options are D, G, M, and N. Plan G is by far the most popular of the four.

The benefit terms are identical across those plans and have been for years:

• 80% of billed charges for medically necessary emergency care that begins during the first 60 days of a trip outside the U.S.
• A $250 annual deductible you pay first.
• A $50,000 lifetime maximum, applied across all your trips combined.
• You pay the remaining 20% coinsurance.

Run the Lisbon hip fracture through that filter. Say the foreign hospital bill is $15,000. You pay the $250 deductible, Medigap pays 80% of the remaining $14,750 (about $11,800), and you pay the other 20% (about $2,950). A $15,000 catastrophe becomes a $3,200 inconvenience. The benefit draws down your $50,000 lifetime bucket by roughly $11,800.

Where the Medigap Benefit Stops Working

Three limits matter.

• First is the 60-day rule. Get sick on day 62 of a Mediterranean cruise and the foreign-travel emergency benefit generally does not apply.
• Second is the $50,000 lifetime maximum. A serious hospitalization combined with a medical evacuation can exhaust that benefit surprisingly quickly. Air ambulance transportation alone can cost tens of thousands of dollars and, in some cases, far more.
• Third is the emergency-care requirement. A planned hip replacement in Costa Rica is not covered. Neither is the prescription you fill at a pharmacy in Paris.

This is where travel medical insurance fills the gap. A short-term policy purchased for a specific trip typically offers higher emergency medical limits, dedicated medical evacuation coverage, and protection that lasts for the entire trip rather than just the first 60 days. Many policies provide evacuation benefits ranging from several hundred thousand dollars to $1 million or more, allowing transportation to an appropriate medical facility when local care is inadequate. For travelers spending meaningful time overseas, a standalone travel medical policy is often a more comprehensive solution than relying solely on Medicare-related coverage.

What to Do Before Your Next Trip

1. Check your Medigap letter. If you have Plan D, G, M, or N (or the older C or F), you already have the 80% foreign emergency benefit. If you have Plan A, B, K, or L, you don’t, and switching plans outside your one-time 6-month Medigap open enrollment window means medical underwriting in most states.
2. Buy a per-trip travel medical policy for any trip longer than 60 days, any trip with significant medevac risk (cruises, remote destinations, adventure travel), or once you’ve used a meaningful share of your $50,000 Medigap lifetime cap. Compare standalone policies rather than the add-on the airline offers at checkout.
3. Carry proof of coverage with you. Foreign hospitals expect payment up front and reimburse you later. Keep itemized bills, translated if possible, and file the Medigap claim within the timeframe your insurer requires.
