46 CFR § 10.304 - General medical exam.
(a) The general medical exam must be documented and of such scope to ensure that there are no conditions that pose significant risk of sudden incapacitation or debilitating complication.

The Coast Guard will provide guidance on the conduct of general medical exams. Examiners should be familiar with the content and recommended medical evaluation data compiled in the medical guidelines.
