Connective tissue and disc stenosis of intervertebral foramina of head 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 spine due to connective tissue overgrowth or disc material in the head region, potentially affecting nerves in the upper neck and head.

Coding Tips

  • •This code involves soft tissue (connective tissue and disc) rather than bone; ensure documentation reflects this distinction
  • •Document associated symptoms such as headaches, neck pain, or neurological deficits
