K91.858
ICD-10-CMThis code represents any complication of an intestinal pouch (e.g., ileal pouch, Kock pouch) that is not specifically classified elsewhere. These pouches are surgically created from the small or large intestine, often after a colectomy, to restore bowel continuity and function. Complications can range from functional issues to structural problems.
Use this code when documentation specifies a complication of an intestinal pouch that doesn't have a more specific ICD-10-CM code. This includes issues like pouchitis not otherwise specified, pouch dysfunction, or structural changes not meeting criteria for other specific codes. Documentation should clearly link the complication to the presence of an intestinal pouch.
