Original Medicare does not cover incontinence supplies such as adult diapers and liners. That’s because these supplies are thrown away after use (not durable), and therefore do not qualify as Durable Medical Equipment (DME). However, if you are hospitalized or admitted to a skilled nursing facility, Medicare Part A will cover diapers for you. Medicare Part B does cover other incontinence products like external urinary collection devices and disposable catheters for intermittent, self-catheterization when basic coverage criteria are met and the individual or caretaker can perform the procedure.
