Spondylolisthesis, lumbar region

This code represents the anterior or posterior displacement of a vertebra over the one below it, specifically occurring in the lumbar spine. This slippage can result from degenerative changes, trauma, or congenital defects, leading to symptoms such as low back pain, radiculopathy, or neurological deficits.

Use this code when documentation clearly indicates a diagnosis of spondylolisthesis affecting the lumbar region. This diagnosis is typically supported by imaging studies such as X-rays, CT scans, or MRI, which confirm the vertebral displacement. It is appropriate for both symptomatic and asymptomatic cases identified in the lumbar spine.

• Specify the type of spondylolisthesis (e.g., degenerative, isthmic) if documented, using more specific codes when available.
• Always code any associated pain, radiculopathy, or neurological deficits separately to fully capture the patient's condition.
• Ensure the documentation clearly states "lumbar region" to support the use of this site-specific code.
