Article 50 of Social Insurance Law

The Institution shall remain responsible for implementing the provisions of this Part if the insured person develops symptoms of an occupational disease during the period determined by the result of the medical examination pursuant to the provisions of the preceding Article, even if he takes up work that does not give rise to this disease. The Institution's obligation shall lapse if the insured person does not present himself for the medical examination referred to in the preceding Article within six months from the date of termination of his service or within one month from the date determined by the result of the previous medical examination. The Director General of the Institution may excuse the delay stipulated in the preceding paragraph if the insured person presents an acceptable excuse and the result of the medical examination establishes that this delay has not resulted in any change in the condition arising from an external factor.
