Does Original Medicare (Part A and Part B) pay for inpatient or outpatient care outside the U.S.?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
Original Medicare (Parts A and B) generally does not pay for inpatient or outpatient care received outside the United States, with only a handful of tightly defined exceptions where Medicare will cover care provided abroad and then only for services that would otherwise be covered under Original Medicare [1] [2]. Private plans tied to Medicare—Medicare Advantage and some Medigap supplements—may offer additional, limited international emergency benefits, but those are plan-dependent and not a replacement for comprehensive travel medical insurance [3] [4].
1. What “outside the U.S.” means and the baseline rule
Medicare treats “outside the U.S.” as anywhere beyond the 50 states, Washington, D.C., and U.S. territories such as Puerto Rico and Guam, and in most such situations Original Medicare will not pay for health care received abroad [5] [1]. Medicare’s published guidance and fact sheets state plainly that Original Medicare has limited travel medical coverage and “usually doesn’t cover health care while you’re traveling outside the U.S.” [1] [2].
2. The narrow exceptions where Medicare may pay
There are specific, rare circumstances in which Medicare will pay for services obtained outside the United States, and when it does the program only pays for services that would be covered at home under Parts A and B; beneficiaries must also meet any other Medicare requirements for those services [1] [2]. Government fact sheets and advisories note that these exceptions are limited and that beneficiaries may need to submit itemized bills themselves because foreign providers usually do not bill Medicare directly [5] [4].
3. Inpatient (hospital) versus outpatient (doctor/clinic) treatment under the exceptions
When an exception applies, Medicare can cover inpatient hospital services and outpatient medical services only to the same extent those services would be covered in the U.S.—for example, medically necessary hospitalization or physician services that meet Medicare’s criteria—because payment is restricted to services otherwise payable by Original Medicare [2] [1]. Sources emphasize that such payments are the exception and not the rule; routine outpatient visits, elective care, and prescriptions bought overseas are typically not covered [4] [3].
4. How Medicare Advantage and Medigap change the picture
Medicare Advantage plans must at a minimum cover everything Original Medicare covers, but many Advantage plans are sold with supplemental emergency overseas benefits that can pay for urgent or emergency care while traveling abroad—coverage that varies by plan and should be confirmed with the insurer [3] [6]. Some Medigap (Medicare Supplement) plans offer international emergency coverage with specified deductibles, coinsurance, and lifetime limits (examples cited in private guides), providing a narrow safety net for travelers that Original Medicare lacks [4] [7].
5. Practical realities, paperwork and limits beneficiaries face
Even when a rare exception applies, beneficiaries may face practical hurdles: foreign hospitals rarely file claims with Medicare, reimbursement may require submitting detailed, itemized bills, and Medigap emergency benefits usually include a deductible and lifetime maximums—factors that can leave travelers with significant out-of-pocket exposure [5] [4] [7]. Consumer-facing insurers and advocacy resources uniformly recommend buying separate travel medical insurance for robust protection because Medicare coverage abroad is minimal and unreliable for routine or elective care [8] [9].
6. Conflicting messages, incentives and who benefits from certain narratives
Government sources and neutral consumer advocates consistently present the limited-coverage message, while private insurers and Medicare Advantage marketers highlight plan perks that expand travel protections—an incentive to sell Advantage or Medigap products even though those benefits differ widely by plan, creating potential for confusion or overpromise [6] [3]. Reporting and commercial pages may emphasize exceptions or supplemental plan options; readers should weigh the source’s commercial interest before assuming broad coverage outside the U.S. [9] [10].
