HCPCS Level II code T4543 denotes an adult-sized disposable incontinence product: a protective brief/diaper in sizes above extra large, billed per unit. This supply-centric code identifies a common durable medical supply used to manage moderate-to-severe urinary or fecal incontinence in adults across home and institutional care settings. Nationally, such products are essential for patient dignity, infection control, and caregiver workload management, and they intersect with coverage policies for durable medical equipment and supplies.

Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of coverage contexts and payer considerations, typical sites of service where T4543 is billed, and a concise description of the product and billing unit. The publication outlines common billing modifiers (listed separately) and notes limitations where input data are not available.

This summary equips billing managers, revenue cycle staff, and policy analysts with a clear definition of the code, its clinical and operational relevance, and what to expect when reviewing claims or setting coverage policies for adult disposable protective briefs sized above extra large.
