Subluxation complex (vertebral) of lumbar region

This diagnosis code signifies a functional spinal lesion in the lower back, characterized by altered joint mechanics, nerve interference, and localized inflammation. It represents a segmental dysfunction of the lumbar vertebrae without frank dislocation or fracture.

This code is appropriate for documenting chiropractic or osteopathic manipulative treatment for patients presenting with lumbar spine pain or dysfunction attributed to vertebral subluxation. Documentation should clearly indicate findings such as restricted range of motion, tenderness, asymmetry, or tissue texture changes in the lumbar region.

• Do not use for frank dislocations or fractures; these require specific injury codes.
• Always specify the spinal region affected (e.g., lumbar in this case).
• Ensure documentation supports the clinical findings of subluxation, not just general back pain.
