HCPCS L1930: Ankle-foot orthosis, plastic or other material

Use L1930 when a prefabricated ankle foot orthosis (AFO) with fitting and adjustment is sufficient. If substantial modifications are required during fitting (beyond minimal self-adjustment), L1910 may be more appropriate. Use custom-fabricated codes like L1940 when patient anatomy or condition necessitates full customization.

Generally, a valid Standard Written Order (SWO) and documentation of medical necessity suffice for prefabricated orthoses. Face-to-face evaluation requirements typically apply to custom-fabricated orthoses. Always check local carrier policies.

Modifications such as trimming, bending, or molding (with or without heat) done by a qualified provider—beyond basic strap adjustments—qualify the device as custom-fitted prefabricated, validating use of L1930.
