IMPORTANT: Yes, indeed, Article 73 no longer applies to pensioners. But Article 72 continues to cover them for all medical costs linked to an accident (up to 80-85%).
HOSPI SAFE SICKNESS/ACCIDENT will continue to reimburse you at 100% for costs linked to any hospitalisation linked to an accident.
On the other hand, if you wish to continue to benefit from a lump sum in case of death resulting from an accident, or in case of any permanent disability, then yes, you should subscribe to the AIACE accident policy.
