Acquired spondylolisthesis

This code describes the anterior slippage of one vertebral body over another due to degenerative changes, trauma, or other acquired conditions, rather than a congenital defect. It typically results from instability in the spinal column, often affecting the lumbar region.

Use this code for patients diagnosed with spondylolisthesis that developed after birth, such as from osteoarthritis, disc degeneration, or fracture. Documentation should clearly state "acquired" or specify a non-congenital etiology for the vertebral slippage.

• Differentiate carefully from congenital spondylolisthesis (756.12).
• Specify the exact vertebral level if documented (e.g., L4-L5).
• Code any associated pain or neurological symptoms separately.
