Clinical & Coding Specifications

Clinical Context

A 78-year-old female resident of a skilled nursing facility with chronic urinary incontinence and limited mobility requires routine disposable underpads to protect bedding and chairs. The nursing staff documents episodes of leakage during transfers and nighttime care. The licensed practical nurse obtains an order from the attending physician specifying provision of small disposable underpads T4542 for bedside use. The supply is delivered to the facility and charted in the resident’s durable medical supply log. Usage is tracked against care plans for incontinence management and wound prevention for perineal skin integrity.
