Subluxation complex (vertebral) of upper extremity

This code signifies a vertebral subluxation complex affecting the cervical or thoracic spine that manifests with symptoms or findings in the upper extremity. It indicates a functional biomechanical lesion of a vertebra, often involving nerve interference, leading to referred pain, numbness, tingling, or weakness in the arm or hand.

Apply this code when documentation explicitly states a vertebral subluxation complex with associated upper extremity symptoms. This is commonly seen in chiropractic or osteopathic manipulative treatment settings. Physician notes should clearly link the spinal subluxation to the patient's upper extremity complaints.

• Ensure the documentation specifies "upper extremity" involvement; otherwise, a more general subluxation code may be appropriate.
• This code is typically a primary diagnosis for chiropractic services but can be a secondary diagnosis if the primary condition is another musculoskeletal disorder.
• Distinguish from nerve entrapment syndromes (e.g., carpal tunnel) unless the subluxation is explicitly identified as the cause.
