What's actually on a cruise ship medically
Cruise ships carry a small medical clinic staffed with one to three physicians and a handful of nurses. The facilities are designed for routine medical issues — seasickness, minor injuries, common illnesses, prescription refills — and basic emergency stabilization. They're not designed for surgery, complex cardiac care, stroke treatment, severe burns, or anything requiring imaging beyond basic X-ray.
When a serious medical event happens on a ship, the clinic stabilizes the patient and the captain decides whether to divert to the nearest port with adequate medical care, hold position for a helicopter evacuation, or continue to the next scheduled port. All three options are expensive, and the cost falls on the patient — not the cruise line.
What evacuation actually costs
Helicopter medical evacuation from a ship at sea typically runs $30,000–$100,000+ depending on distance and the receiving hospital. If the evacuation requires fixed-wing air ambulance for a long-distance transfer (Caribbean back to the US, for example), costs can exceed $100,000 easily.
Cruise lines don't carry medical evacuation insurance for passengers. The passenger or their family pays — typically up front, before the evacuation is initiated, with a credit card hold for the estimated cost. Travelers without insurance have been in situations where the credit card hold exceeded their available credit and the family had to scramble to wire funds before treatment could continue.
Travel insurance with emergency medical evacuation coverage handles this end-to-end: the insurer coordinates the evacuation, advances the funds, and bills the policy. No upfront cost to you, no negotiating with the ship's clinic about logistics.
Why regular health insurance doesn't help
US health insurance — including Medicare — generally does not cover medical care outside the United States. International cruise itineraries usually leave US waters, which is where coverage stops. Even when ships return to US ports, in-cruise medical care delivered in international waters is typically not covered.
Some plans offer limited international coverage with high deductibles and reimbursement-only models (you pay, then submit a claim). For a $40,000 evacuation bill, even a 'covered' claim under your health insurance might leave you out-of-pocket for tens of thousands.
Medical-only is cheap
A standalone medical-only travel insurance policy — no trip cancellation, just emergency medical and evacuation — typically runs $30–$80 for a week-long cruise. The coverage is substantial: $50,000–$500,000 in medical, $250,000–$1M in evacuation, often with no deductible.
For travelers whose cruise bookings are refundable (or who simply aren't worried about cancellation), medical-only is the highest-leverage policy in all of travel insurance. You're insuring against catastrophic financial loss for the cost of a couple of drinks at the pool bar.
Comprehensive policies that include trip cancellation typically include medical coverage too, so if you're already buying the full policy you're covered. Medical-only exists for travelers who specifically don't need cancellation coverage but still want the medical safety net.
Bottom line
If you're taking a cruise — especially internationally, especially with anyone over 60, especially with anyone managing a health condition — travel medical insurance is the closest thing to a no-brainer in travel insurance. The exposure is enormous, the coverage is cheap, and the alternative is paying out of pocket for one of the highest-cost medical scenarios in modern travel.
