Subluxation complex (vertebral) of rib cage

This code describes a vertebral subluxation complex affecting the rib cage region of the spine. It indicates a functional lesion or mechanical derangement in the thoracic spine, where altered joint motion, segmental dysfunction, and associated neurological, muscular, or vascular effects are present, specifically impacting the ribs and their articulations.

Use this code when documentation from a chiropractor, osteopath, or other qualified provider specifies a vertebral subluxation complex located in the thoracic spine, explicitly involving the rib cage. This diagnosis is typically supported by findings of altered segmental motion, tenderness, asymmetry, or tissue changes in the costovertebral or costotransverse joints.

• Ensure the documentation clearly specifies "subluxation complex" and its location in the rib cage/thoracic region.
• Do not confuse with simple sprains/strains (e.g., S22.x for rib fracture or S29.0xxA for rib cage injury) unless subluxation complex is also explicitly diagnosed.
• This code is often used as a primary diagnosis for chiropractic manipulative treatment (CMT) services.
