Frequently asked questions

Select L3908 when the device is prefabricated and requires only minimal self-adjustment. If a clinician molds, trims, or shapes the orthosis, a custom-fitted or custom-fabricated code, such as L3906 (or L3915 if using a prefabricated base), must be used.

There’s no universal Medicare frequency limit, but replacements within the item’s useful lifetime can be denied unless there’s documented medical need or damage. Some state Medicaid programs and private payers may require prior authorization, especially for repeat billing, so always check local policy.
