Proof of delivery (POD) documentation must be maintained by the supplier and made available to the Medicare contractor upon request.
Objective knee instability must be supported by documentation of the beneficiary’s physical examination including the joint laxity test(s) performed when required by the orthosis coverage criteria.

For coverage based on medial or lateral tibiofemoral osteoarthritis, documentation must show diagnosis and that the beneficiary is ambulatory, has pain or reduced mobility/function from OA, that the orthosis provides varus/valgus adjustment, and that the beneficiary is willing to use the orthosis.
