Revised Coding Guidelines for Ankle-Foot Orthoses

Consistent with the revision of the DME MAC LCD for Ankle-Foot/Knee-Ankle-Foot Orthoses - Policy Article - Effective January 2013, the PDAC contractor has revised the definition for L1960 from when this article was originally published in December 2011. Please Note: The reference to a specific measurement for the height of a L1960 AFO has been removed.

All other guidelines published when this article was posted to the PDAC website on 12/21/2011 remain in effect. These guidelines are intended to provide further definition and clarification for certain orthoses and assist suppliers in correct coding of these devices.

L2340 Addition to lower extremity, pre-tibial shell, molded to patient model
A pre-tibial shell, custom fabricated, provides a rigid overlapping interlocking anterior tibial control between the tibial tuberosity to a point no greater than 3 inches proximal to the medial malleolus. The pre-tibial shell can be constructed from thermosetting materials, thermoplastics, or composite type materials.

L1906 Ankle foot orthosis, multiligamentous ankle support, prefabricated, includes fitting and adjustment 
A multiligamentous ankle support provides control of the ankle joint between the medial and lateral malleoli while allowing for dorsiflexion and plantar flexion. This off-the-shelf ankle support includes a rigid stirrup and foot plate which provides functional tracking of the ankle with hind-foot and mid-foot stability during ambulation. This, in conjunction with wrap-around straps and the inherent gauntlet design, offers areas of multiligamentous support as described by the code. There are no additional HCPCS codes for this type of prefabricated ankle orthosis.

L1960 Ankle foot orthosis, posterior solid ankle, plastic, custom-fabricated
An ankle foot orthosis (AFO) provides ankle control for patients with musculoskeletal or neuromuscular dysfunction. The AFO is designed to provide rigid immobilization of the ankle-foot complex in the sagittal, coronal, and transverse planes. The custom fabricated solid ankle AFO can be constructed from thermosetting materials, thermoplastics, or composite type materials.

Effective for claims with dates of service on or after 4/1/2012, the only products which may be billed to Medicare using code L1906 (Ankle foot orthosis, multiligamentus ankle support, prefabricated, includes fitting and adjustment) are those for which a written coding verification has been made by the PDAC contractor and that are listed in the Product Classification Matrix of the DMECS maintained on the PDAC website. Products which have not received coding verification review from the PDAC must be billed with code A9270.

For questions about correct coding, contact the PDAC Contact Center at 877-735-1326 during the hours of 8:30 a.m. to 4:00 p.m. CT, Monday through Friday, or email the PDAC by completing the DME PDAC Contact Form located on the PDAC website.
