For this purpose, the seafarer shall submit himself to a post-employment medical examination by a company-designated physician within three working days upon his return except when he is physically incapacitated to do so, in which case, a written notice to the agency within the same period is deemed as compliance.

The facts further show that after Dr. Peralta found Bastol unfit for sea duty, PPI—the local representative of PIC, the insurer of PSL—referred him
