Spondylolisthesis, site unspecified

This code represents the anterior or posterior displacement of a vertebra relative to the one below it, without specifying the affected spinal region. It indicates a slippage of the vertebral body, often due to degenerative changes, trauma, or congenital defects. The condition can lead to spinal instability, pain, and neurological symptoms.

Use this code when the medical record clearly documents spondylolisthesis but does not specify the exact spinal segment (e.g., cervical, thoracic, lumbar, sacral). This is appropriate when the physician has diagnosed spondylolisthesis but further diagnostic imaging or detailed examination to pinpoint the level is pending or not yet performed. Documentation should confirm the presence of vertebral slippage.

• Avoid using this code if the specific spinal segment of the spondylolisthesis is documented; instead, use a more precise code from the M43.1- subcategory.
• Always review the entire medical record for laterality and specific vertebral levels to ensure the most accurate code is selected.
• Consider sequencing this code with codes for associated pain (e.g., M54.5 for low back pain) or neurological deficits if documented.
