Connective tissue and disc stenosis of intervertebral foramina of cervical region

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Narrowing of the nerve passages in the cervical spine due to connective tissue overgrowth or disc material, which can cause neck pain, arm pain, or weakness.

Coding Tips

  • •Specify the cervical level (C1-C7) and whether the stenosis is central or lateral
  • •Document whether disc herniation, ligamentum flavum hypertrophy, or other soft tissue involvement is present
