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

Y83.3: Surgical operation with formation of external stoma

An external stoma is a surgically created opening on the surface of the body connecting to an internal organ or passage. This procedure, represented by ICD-10 Y83.3, can be performed as part of treatment for various health issues. The stoma can connect with the digestive or urinary system, and allows wastes to be removed from the body when the usual route is obstructed or needs to be bypassed. The formation of a stoma is generally a major surgical procedure and is often, but not always, intended to be temporary. After this operation, the waste is collected in a small bag attached outside the body. Patients with a stoma often require ongoing specialist care and support.
