CG Modifier Usage

When billing spinal orthoses, the CG modifier is only to be appended to the following spinal garments when they are made primarily of non-elastic material (e.g., canvas, cotton, or nylon) or have a rigid posterior panel:

  • L0450 - TLSO, flexible, provides trunk support, upper thoracic region
  • L0454 - TLSO, flexible, provides trunk support, extends from sacrococcygeal junction to above T-9 vertebra
  • L0621 - Sacroiliac orthosis, flexible
  • L0625 - Lumbar orthosis, flexible, provides lumbar support
  • L0628 - Lumbar-sacral orthosis, flexible provides lumbo-sacral support

For modifier assistance, please refer to the Modifier Lookup Tool and the Spinal Orthoses TLSO and LSO Policy Article A52500.
