I don't necessarily disagree with some of the comments here. Scuba is a self-regulating industry. But i voted "yes".
A medical form is required by our training agencies for every class. If certain things are checked as a "yes", a physician approval is required. Some classes (divemaster and instructor) require a physician sign-off. Even beyond that, i will sometimes require a student to provide a physician sign-off if i am unsure about their physical abilities. I very often do this for tech students. I require the medical from students to protect both myself AND the student. As I am also a paramedic, my threshold for medical tends to be a bit different than many other instructors.
