ICD-10 code for subluxation vertebral complex

The ICD-10-CM code for subluxation vertebral complex is M99.19 (Subluxation complex (vertebral) of abdomen and other regions). The official index lists 24 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M99.19.

Within M99.1, choose M99.19 (of abdomen and other regions) only when documentation doesn't support a more specific option: of head region (M99.10), of cervical region (M99.11), of thoracic region (M99.12), of lumbar region (M99.13), of sacral region (M99.14), of pelvic region (M99.15), of lower extremity (M99.16), of upper extremity (M99.17) and 1 more.

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 562 (Fracture, Sprain, Strain and Dislocation Except Femur, Hip, Pelvis and Thigh with MCC, relative weight 1.398), DRG 563 (Fracture, Sprain, Strain and Dislocation Except Femur, Hip, Pelvis and Thigh without MCC, relative weight 0.8985), DRG 963 (Other Multiple Significant Trauma with MCC, relative weight 2.6363), DRG 964 (Other Multiple Significant Trauma with CC, relative weight 1.4972) and DRG 965 (Other Multiple Significant Trauma without CC/MCC, relative weight 1.0059), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue) and MDC 24 (Multiple Significant Trauma), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
