HCPCS Level II code A4330 designates a perianal fecal collection pouch with adhesive, each — a single-use external fecal collection supply used for continence management. This supply-level code matters nationally because it affects durable medical equipment (DME) coverage, home and outpatient care workflows, and cost and utilization tracking for patients requiring external fecal management. Coverage and reimbursement for supplies like A4330 influence patient access to appropriate continence care and can drive clinical decisions about in-home management versus facility-based care.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with fecal incontinence, perianal skin breakdown, or recent anal sphincter surgery who requires a perianal fecal collection pouch for short- to medium-term management of stool diversion. The device A4330 (perianal fecal collection pouch with adhesive, each) is applied at bedside in an outpatient wound clinic, long-term care facility, home health visit, or inpatient ward. The clinical workflow includes assessment of perianal skin integrity, selection of an appropriately sized pouch, cleansing and drying of the perianal area, application of the adhesive pouch to form a seal around the anus, education on pouch maintenance and disposal, and documentation of reason for use, size, lot number, and patient tolerance. Typical scenarios include management of fecal incontinence from neurogenic bowel (e.g., spinal cord injury), protection of perianal wounds or skin grafts from stool contamination, temporary diversion after anorectal surgery, or palliative care for uncontrolled diarrhea. Device replacement frequency depends on device adhesion, skin condition, and stool consistency; clinicians monitor daily for leakage, perianal dermatitis, and need for skin barrier products.
