Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with a longstanding ileostomy presents for surveillance and evaluation of intermittent bleeding and abdominal cramping. The enterostomal nurse and colorectal surgeon coordinate care. The patient arrives to an outpatient endoscopy suite where pre-procedure vitals and informed consent are completed. Conscious sedation is administered per facility protocol. The colorectal surgeon introduces a flexible endoscope through the existing ileostomy stoma to visualize the distal ileum mucosa. Areas of erythema, ulceration, or nodularity are inspected. Targeted cold or forceps biopsies are obtained from suspicious mucosa and sent to pathology for histopathologic examination. Procedure documentation includes stoma site, extent of ileal intubation, findings, number and location of biopsies, estimated blood loss, any immediate complications, and post-procedure recovery instructions. Typical sites of service are outpatient endoscopy suites, ambulatory surgery centers, and inpatient wards when medically indicated. The service type is a diagnostic endoscopic evaluation of the ileum via an established stoma with biopsy as indicated (44382).
