Spondylolisthesis, cervical region

This code identifies the anterior or posterior displacement of a vertebra in the cervical spine relative to the vertebra below it. This condition can result from congenital defects, degenerative changes, trauma, or pathological processes affecting the pars interarticularis or facet joints. It often leads to neck pain, radiculopathy, or myelopathy depending on the degree of slippage and nerve involvement.

Assign this code when documentation clearly indicates spondylolisthesis specifically located in the cervical region. This diagnosis is typically supported by imaging studies such as X-rays, MRI, or CT scans demonstrating the vertebral slippage. Use this code for both symptomatic and asymptomatic cases where the cervical spondylolisthesis is identified.

• Ensure the documentation specifies "cervical region" to differentiate from other spinal areas.
• Do not confuse with spondylolysis (M43.0-) which is a defect in the pars interarticularis without slippage.
• Code any associated neurological manifestations (e.g., radiculopathy, myelopathy) separately, following sequencing guidelines.
