Hand-Finger Orthoses (L3923) – Use of CG Modifier

If a hand-finger garment is made primarily of elastic material, it must be billed with code A4466 (Garment, belt, sleeve or other covering elastic or similar stretchable material, any type, each) and not code L3923. Claims billed with code A4466 will be denied as noncovered, no benefit category. Effective for claims with dates of service on or after July 1, 2010, if an L3923 orthosis has a rigid plastic or metal component, the supplier must add the CG modifier (policy criteria applied) to the code. Claims for L3923 billed without a CG modifier will be rejected as incorrect coding.
