I've never used the medical facilities on a cruise, but have read that the basic office visit can run $50 to $80, and $80 to $110 if the doctor has to make a "house call" to your cabin. This does not include medication or other supplies. Some ships have fairly high-tech facilities with live-time satellite feeds to big time trauma centers such as Cedars-Sinai Hospital. The ship's doctor can consult with an ER doctor or specialist. People have gone this far and found out that they had a hefty bill to pay - $1500 or more.
