Medicare usually does not cover health care outside the United States. On a cruise ship, Medicare Part B may pay only if the doctor is legally authorised and the ship is in a US port or no more than six hours from one. Outside that window, Medicare's own wording is that "you pay all of the costs, in most cases."
I want to start with the single most important fact on this page, because most people over sixty-five have never heard it and it is published in black and white on Medicare's own website.
Six hours. On a Western Caribbean sailing you are outside that window for most of the week.
And the State Department is equally direct about who picks up the bill: "The U.S. government does not pay medical costs for U.S. citizens traveling abroad," and "U.S. Medicare and Medicaid do not pay for medical care outside the United States."
What that means in practice on a cruise
Three separate things can go wrong, and they cost wildly different amounts.
| You get sick onboard | The ship's medical centre treats you and bills you. You are paying, unless you have cover that reimburses you. |
|---|---|
| You get sick or hurt ashore | You are in a foreign healthcare system, paying foreign prices, usually up front. |
| You need to be moved | This is the one that ruins people. The State Department strongly recommends medical evacuation coverage, particularly for places with limited medical facilities — and getting someone off a ship or off an island and home is the single largest bill in travel. |
What the State Department says to check before you buy
This is their own published checklist, and it is a good one. Confirm that a policy covers:
- The countries you are actually visiting. Your itinerary, not just "the Caribbean".
- Emergency medical care.
- Medical transportation back to the United States. This is the expensive piece, and it is not always included.
- Your current medical conditions. Read that line twice if you have any.
- The activities you have planned. Some policies exclude things you would not think of as risky.
They also recommend confirming the insurer has a 24-hour help line you can call during the trip. On a ship in a different time zone at two in the morning, that stops being a detail.
Cruise-specific things worth asking about
- Missed connection and missed departure. Flights that fail to get you to the pier are a cruise-specific problem.
- Itinerary change. Ships skip ports. Whether that is covered, and what it pays, varies enormously between policies.
- Pre-existing conditions. Many insurers offer a waiver, but it usually depends on buying within a set number of days of your first trip payment. The window is short and it differs by insurer, so if this matters to you, buy early rather than late.
- Cancel for any reason. Usually an add-on, usually costs more, usually reimburses only part of the trip, and usually has its own purchase deadline.
- Who is covered. If you are travelling with grandchildren, check they are on the policy.
These are the questions to ask, not answers I can give you. The numbers and windows are set by each insurer and change, and the only document that tells you the truth about your cover is the policy itself.
Where I send people to compare
We use Squaremouth, which is a comparison marketplace rather than an insurance company. You enter your trip, your dates and the ages of everyone travelling, and it lays out plans from more than twenty insurers so you can read and compare them yourself.
What I like about the model is that you are reading actual policies side by side instead of being sold one. They publish more than 4.7 million trips insured and twenty years of operation, and they run a claims advocacy service they call the Zero Complaint Guarantee, where their team helps mediate a claim or an appeal if one goes wrong. They are licensed in California as SPG Insurance Solutions, License No. 0L09546, BBB accredited and a member of the US Travel Insurance Association.

Here is what I am not going to do with it. I am not an insurance agent or a broker. I cannot tell you which policy suits you, because I do not know your health, your budget or what you have already got. Anyone on the internet who tells you "buy this exact plan" without knowing those things is either guessing or selling.
What I can do is tell you why it matters, tell you what to compare, and point you somewhere you can read the policies yourself. What you buy is your call.
Two things people get wrong
"My credit card covers me." Some cards do carry travel protections, and some of those are decent. But card benefits are usually trip cancellation and baggage rather than serious medical cover and evacuation, and the limits are often lower than people assume. Read the benefits guide for your specific card before you rely on it.
"I will buy it later." The features people most want — the pre-existing condition waiver, cancel for any reason — are usually the ones with a purchase deadline tied to your first trip payment. Wait, and those doors close quietly. If you are going to insure a trip, price it when you book it.
Questions I get asked
Does Medicare really stop working on a cruise?
Broadly, yes. Medicare usually does not cover care outside the US. The exception is medically necessary services on board when the ship is in a US port or no more than six hours from one, with a doctor legally authorised to provide them.
Does the cruise line's own insurance count?
It is a real product and some people are happy with it. Compare it against outside policies on cover limits, medical evacuation and pre-existing conditions before you assume it is the best option simply because it is the easiest to click.
Is it worth insuring a cheap cruise?
The fare is rarely the risk. Medical care abroad and getting you home are the risk, and those do not get cheaper because your cabin was discounted.
What about a comped casino cruise?
Your cabin being free does not make the trip cancellation-proof, and it certainly does not cover a medical bill. See what a free cruise actually costs.
Do I need evacuation cover for the Caribbean?
The State Department recommends it particularly for areas with limited medical facilities. Several ports we cover publish very little about their own medical provision, which tells you something.
We are not insurance agents or brokers, we do not sell policies, and nothing here is a recommendation that any particular policy suits your circumstances. Coverage terms, waiting periods and purchase deadlines are set by each insurer and change over time. Read the policy document before you buy.

Ports change their rules and their prices. Check the official pages above before you sail.
Independent tours usually cost less than the ship's, and are often run by the very same local operator. Look for a listing tagged Worry-Free Shore Excursion — Viator backs those with what it calls a "Back to Ship Guarantee," which is the bit that takes the worry out of booking on your own.
- Viator publishes 400,000+ travel experiences
- Full refund on most experiences cancelled at least 24 hours ahead
- Back to Ship Guarantee on Worry-Free listings
