Spondylolisthesis, thoracic region

This code identifies the anterior or posterior displacement of a vertebra over the one below it, specifically occurring within the thoracic spine. This condition can result from congenital defects, degenerative changes, trauma, or pathological processes affecting the vertebral column.

Use this code when documentation clearly indicates spondylolisthesis affecting any segment of the thoracic spine (T1-T12). This diagnosis is typically supported by imaging studies such as X-rays, CT scans, or MRIs, along with a physician's clinical assessment.

• Ensure the documentation specifies "thoracic region" to differentiate from cervical or lumbar spondylolisthesis.
• Do not confuse with spondylolysis (M43.0-), which is a defect in the pars interarticularis without displacement.
• Code any associated neurological manifestations (e.g., myelopathy, radiculopathy) separately and sequence according to the encounter's primary reason.
