What 44380 covers
Code 44380 reports diagnostic inspection of the ileum by passing an endoscope through an existing ileostomy. Gastroenterologists and colorectal surgeons may use it to evaluate symptoms such as bleeding or pain, or suspected ileal inflammation, in a patient with a stoma. Collection of cells or fluid by brushing or washing may be part of the examination. This code is not for an examination that includes tissue biopsy or a therapeutic maneuver, and it is distinct from examination of an ileal pouch or colonoscopy through a stoma.
Document the stoma route, the ileal examination, the clinical indication, and any brushing or washing performed. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures occur in one session, Medicare pays the highest-valued procedure in full and applies the standard reduction to the others. Modifier 50 is inappropriate for this anatomy. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
