Yes, - commercial divers - in industrialised western nations, (European Union, Australia. Norway, New Zealand), and I believe, in parts if not all of the US - undergo an annual and very thorough medica examinationl; - no pass = no job. The diving contractors (employers) are bound to do this in order to comply with govenment OH&S regulations. . . . and probably also complying with their insurance policy terms & conditions.
