HCPCS Code L2999: Lower Extremity Orthoses, Not Otherwise Specified

HCPCS code L2999 is a miscellaneous code for "Lower extremity orthoses, not otherwise specified (NOS)." It is used when no specific HCPCS code accurately describes the provided orthotic device. This code typically requires additional documentation to support billing and reimbursement.

Medicare generally allows coverage of HCPCS code L2999, but payment is contingent upon the submission of detailed supporting documentation and compliance with Local Coverage Determinations (LCDs). Coverage depends on demonstrating medical necessity and proper device description; claims often require additional clinical information for approval.

Insurance codes for orthotics are primarily HCPCS codes in the L0112–L4631 range. These include custom-fabricated orthotics, prefabricated custom-fitted orthotics, prefabricated orthoses, and off-the-shelf orthotics.
