Subluxation complex (vertebral) of cervical region

This code signifies a functional spinal lesion in the cervical region characterized by altered joint mechanics, neurological involvement, and/or inflammatory changes. It represents a complex of signs and symptoms indicating a vertebral subluxation, rather than a simple dislocation. This condition often results in pain, restricted range of motion, and potential neurological deficits in the neck and upper extremities.

This code is appropriate when documentation explicitly states "subluxation complex" or "vertebral subluxation" of the cervical spine. It is commonly used in chiropractic and osteopathic settings to describe the primary diagnosis for spinal manipulative therapy. Supporting documentation should detail the specific cervical vertebrae involved and the clinical findings consistent with a subluxation complex.

• Do not confuse with a traumatic dislocation (S13.1xx codes) or a simple subluxation without the "complex" designation.
• Ensure the documentation clearly specifies the cervical region; avoid using this code for other spinal regions.
• This code is often a primary diagnosis, especially for chiropractic services, and may be followed by codes for associated symptoms like pain (e.g., M54.2).
