Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a permanent or temporary abdominal stoma (ileostomy or colostomy) who requires a one-piece drainable ostomy pouch system with an extended-wear adhesive barrier, built-in convexity, and an integrated filter to manage effluent and peristomal contour issues. The patient often presents in a wound, ostomy, and continence (WOC) clinic, outpatient surgical clinic, home health visit, or durable medical equipment (DME) supplier visit. Clinical workflow: the WOC nurse or ostomy-trained clinician assesses stoma shape, peristomal skin integrity, and output characteristics; selects a product with built-in convexity for a retracted or flush stoma and an extended-wear barrier for fragile skin or high-output situations; documents diagnosis, stoma type, pouch features (drainable, filter, one-piece), and medical necessity; obtains DME supplier order and transmits to insurer with supporting notes and ICD-10 diagnosis codes; supplies product and trains patient/caregiver on application, emptying, and troubleshooting; schedules follow-up for skin checks and supply adjustments.
