M89.334

Billable

Hypertrophy of bone, left radius

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

What This Code Means

Abnormal thickening or enlargement of the bone in the left forearm (radius bone). This condition causes the bone to grow larger than normal.

Coding Tips

  • •Verify laterality is documented as 'left' in the medical record before assigning this code
  • •Distinguish from M89.339 (unspecified) - only use M89.334 when left radius is explicitly documented
