Clinical & Coding Specifications
Clinical Context
A typical patient is an older adult or adult with urinary or fecal incontinence requiring an absorbent disposable liner, shield, guard, pad, or undergarment for daily management. The supply is dispensed in outpatient clinical settings such as a primary care clinic, urology or gynecology office, wound-ostomy clinic, durable medical equipment (DME) supplier, or skilled nursing facility; it may also be provided at discharge from an acute care or rehabilitation hospital. The clinical workflow includes assessment of continence status and skin integrity, selection of an appropriate product size and absorbency, patient or caregiver education on application and disposal, documentation in the medical record of medical necessity, and billing the item using HCPCS Level II code T4535. Typical clinical scenarios include patients with neurogenic bladder, post-operative urinary retention with overflow incontinence, advanced dementia with functional incontinence, chronic mobility impairment with inability to toilet independently, or palliative care patients requiring incontinence management to protect skin and maintain hygiene.
