ICD-10 code for Thoracogenic scoliosis

The ICD-10-CM code for Thoracogenic scoliosis is M41.30 (Thoracogenic scoliosis, site unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M41.30.

Within M41.3, choose M41.30 (site unspecified) only when documentation doesn't support a more specific option: thoracic region (M41.34) and thoracolumbar region (M41.35).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 456 (Spinal Fusion Except Cervical with Spinal Curvature, Malignancy, or Infection with MCC, relative weight 7.6244), DRG 457 (Spinal Fusion Except Cervical with Spinal Curvature, Malignancy, or Infection with CC, relative weight 5.3668), DRG 458 (Spinal Fusion Except Cervical with Spinal Curvature, Malignancy, or Infection without CC/MCC, relative weight 4.0388), DRG 551 (Medical Back Problems with MCC, relative weight 1.6358) and DRG 552 (Medical Back Problems without MCC, relative weight 0.9584), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
