Anterior spinal artery comprsn syndromes, cervical region

This code describes a neurological condition resulting from the compression of the anterior spinal artery specifically within the cervical spine. This compression leads to ischemia of the anterior spinal cord, manifesting as motor and sensory deficits below the level of compression.

Use this code when documentation clearly indicates a diagnosis of anterior spinal artery compression syndrome, with the specific anatomical location identified as the cervical region. Supporting documentation should include clinical findings consistent with anterior spinal cord ischemia and imaging (e.g., MRI, MRA) confirming anterior spinal artery compromise in the neck.

• Ensure the documentation specifies "compression" of the anterior spinal artery, not just general spinal cord ischemia.
• Verify the cervical region is explicitly stated; do not use for thoracic or lumbar involvement.
• Consider co-reporting any underlying conditions causing the compression, such as disc herniation or osteophyte formation, if documented.
