To be eligible to enroll in health coverage through the Marketplace, you:
If you have Medicare coverage, you’re not eligible to use the Marketplace to buy a health or dental plan. Learn more about Medicare and the Marketplace.
U.S. citizens living in a foreign country for at least 330 days of a 12-month period are not required to get health insurance coverage for that 12-month period. If you're uninsured and living abroad under this definition, you qualify for a health insurance exemption for plan years 2018 and earlier. This means you don’t have to pay the fee that other uninsured people must pay when they file their taxes.
Note: Starting with the 2019 plan year (for which you’ll file taxes in April 2020), the fee no longer applies. If you don’t have coverage during 2019 or later, you don’t need an exemption in order to avoid the penalty.
See question 12 on this IRS web page to learn more about the rules for people living abroad.

A U.S. national is someone who’s a U.S. citizen or a person who isn’t a U.S. citizen but owes permanent allegiance to the U.S.
U.S. territories can decide whether to create their own Health Insurance Marketplace or expand Medicaid coverage. Residents of a U.S. territory aren't eligible to apply for health coverage using the federal or state Marketplace unless they also qualify as a resident within the service area of a Marketplace.
