Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a surgically created stoma (colostomy, ileostomy, or urostomy) who requires a replacement drainable ostomy pouch with an attached faceplate due to routine wear, appliance failure, peristomal skin concerns, or planned pouch change. The workflow begins in an outpatient wound, ostomy, and continence (WOC) clinic, home health visit, long-term care facility, or surgical clinic. A licensed clinician (WOC nurse, enterostomal therapist, or surgeon) assesses the stoma and peristomal skin, documents stoma type and pouching system needs, selects an appropriate drainable pouch with faceplate (A4375), and supplies the item to the patient. Typical encounters include device fitting and patient education on emptying and skin care, appliance exchange during postoperative follow-up, or supply provision for chronic ostomy maintenance. Usual sites of service are outpatient clinics, durable medical equipment (DME) supplier locations, patient's home, and inpatient hospital settings when a new or replacement appliance is required.
