ICD-10-PCS Code For Lower GI: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group XW0H includes procedures performed to introduce therapeutic, diagnostic, nutritional, physiological, or prophylactic substances into the lower gastrointestinal tract. These ICD-10-PCS codes are used for inpatient documentation when a clinician or proceduralist uses a new technology method to place a substance into lower gastrointestinal anatomical regions. Accurate coding within the ICD-10-PCS XW0H group is essential for proper inpatient reimbursement, as it captures the specific introduction procedure performed and supports clinical documentation accuracy.

Typical Clinical Scenarios

An elderly hospitalized patient with severe Clostridioides difficile colitis who has failed multiple courses of antibiotics and requires restoration of gut microbiota to control recurrent infection; during an inpatient therapeutic colonoscopy the team introduces a microbiota-based live biotherapeutic suspension into the lower gastrointestinal tract using the new technology delivery system to re-establish healthy flora. Typical codes: XW0H7X8
A middle-aged patient admitted for uncontrolled lower GI bleeding after colonoscopic polypectomy where topical hemostasis is needed endoscopically; during an urgent endoscopic procedure, a mineral-based topical hemostatic agent is introduced into the lower GI site via endoscopic approach using the new technology preparation to achieve hemostasis. Typical codes: XW0H886
A hospitalized oncology patient with chemotherapy-associated enteric viral infection who cannot tolerate systemic therapy and requires localized antiviral delivery to the lower bowel; the care team performs an inpatient introduction of a monoclonal antibody or anti-infective agent directly into the lower GI tract via natural or artificial opening using the new technology method to provide targeted therapy. Typical codes: XW0H738, XW0H7R7
