Y83: Surgical operation and other surgical procedures as the cause of abnormal reaction of the patient, or of later complication, without mention of misadventure at the time of the procedure

Y83.5: Amputation of limb(s)

Amputation of limb(s) refers to a surgical procedure that involves the removal of a diseased or injured limb from the rest of the body. This condition might result due to various reasons such as severe injury, infection, frostbite, tumors, or diseases like peripheral arterial disease where the blood flow to the limbs is blocked or reduced. The amputated area might vary from the partial removal of a foot or a hand, to the complete removal of an arm or a leg. Post amputation, a person may experience phantom sensation or phantom pain, where they feel as if the amputated limb is still present or pain is originating from the removed limb. With adequate physical therapy and rehabilitation, individuals can often adjust to life post-amputation and potentially utilize prosthetic limbs to augment mobility and functionality.
