Subluxation complex (vertebral) of thoracic region

This code represents a functional spinal lesion in the thoracic region where there is a misalignment or altered motion of a vertebra, without complete dislocation. It signifies a biomechanical dysfunction of the thoracic spine, often associated with nerve irritation, muscle spasm, or localized pain.

This code is appropriate when documentation indicates a vertebral subluxation complex specifically affecting the thoracic spine, as diagnosed by a chiropractor, osteopathic physician, or other qualified provider. It is typically used for conditions involving segmental somatic dysfunction, often identified through palpation, range of motion assessment, and imaging studies if performed.

• Ensure documentation clearly specifies the thoracic region; avoid using for cervical or lumbar subluxations.
• This code is often a primary diagnosis for chiropractic manipulative treatment (CMT) services.
• Do not confuse with M99.0- codes, which represent segmental and somatic dysfunction without the "subluxation complex" terminology.
