If you are a professional soldier with a cadre above the intermediate level or a noncommissioned officer, you can't assess disabled soldiers due to illness, because it is stipulated in the Regulations on Pensions and Preferential Treatment for Soldiers.
If you are a conscript or junior noncommissioned officer, you will still have irreversible disability and drug dependence after operation and recovery. After consultation between the logistics department of your former army and the doctors in the hospital, there will be a disability grade group discharged from the medical system of the Corps. According to the disability grade standard for military personnel, you are rated as a disabled soldier of level 6 or above due to illness.
