Subluxation complex (vertebral) of lower extremity

This code describes a vertebral subluxation complex affecting the lower extremity. It indicates a functional lesion of the spine where altered alignment, motion, or physiological function of a vertebral segment may impact neurological, muscular, or vascular integrity, manifesting with symptoms in the lower limb.

Use this code when documentation explicitly states a vertebral subluxation complex with associated lower extremity involvement. This is commonly seen in chiropractic or osteopathic manipulative treatment settings where the spinal dysfunction is linked to lower limb symptoms. Supporting documentation should detail the vertebral segment(s) involved and the clinical manifestation in the lower extremity.

• Ensure the documentation clearly links the vertebral subluxation to the lower extremity symptoms.
• Do not confuse this with general lower extremity pain codes (e.g., M79.60-M79.69) unless a vertebral subluxation complex is specifically diagnosed as the cause.
• This code is typically a primary diagnosis for manipulative treatment services when the subluxation is the focus of care.
