Intervertebral disc stenosis of neural canal of lower extremity

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

What This Code Means

Narrowing of the spinal canal caused by a bulging disc that affects nerves going to the legs, potentially causing leg pain or weakness.

Coding Tips

  • •Document which leg(s) are affected and whether symptoms are unilateral or bilateral
  • •Distinguish from M99.55 by confirming lower extremity involvement rather than pelvic region only
