Medical-necessity criteria Medicare (CMS LCD/NCD) generally applies

GENERALLY NOT COVERED: custom foot orthotics (L3000 family) fall under Medicare's statutory exclusion of foot supportive devices (SSA 1862(a)(13); Benefit Policy Manual Ch. 15 foot-care provisions). Exceptions: (1) an orthotic that is an integral part of a covered leg brace; (2) diabetic inserts furnished under the therapeutic-shoe benefit (see the Diabetic Therapeutic Shoes entry, LCD L33369). Outside those exceptions, issue an ABN and bill the patient or their secondary coverage - a Medicare denial here is expected, not a documentation failure. [NEEDS CLINICAL SPOT-CHECK]
