DETERMINATION ON SHIPBOARD SERVICES
We are sorry, but medical services provided on the (vessel/ship's name) cruise ship are not covered. The Medicare
program can make payment for medically necessary shipboard services only if all of the following requirements are met:
1. The services are furnished while the ship is within the territorial waters of the United States (in a U.S. port, or
within 6 hours of departure or arrival at a U.S. port).
2. The services are furnished to an individual who is entitled to Part B benefits;
3. The services are furnished in connection with covered inpatient hospital services;
4. The services furnished on the ship are for the same condition that required inpatient admission;
5. The physician is legally authorized to practice in the country where he or she furnishes the services.
If you have a supplemental insurance policy, you should check with the company carrying that policy to see if they
cover these services and what procedures you should follow in submitting your claim.
If you have questions about this notice, you may call 1-800-MEDICARE (1-800-633-4227) for additional information.
If you believe the determination is not correct, you may request a redetermination. You must file your request within
120 days from the date you receive this notice. A request for a redetermination must be filed either on Form CMS-
20027 or on a written request that includes all of the elements listed below.
