Major osseous defect, left hand

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

What This Code Means

A significant loss or defect in the bone structure of the left hand, which may result from injury, infection, or surgical removal.

Coding Tips

  • •Verify the specific bone affected (carpal, metacarpal, or phalanges) in the clinical documentation for more precise coding if available
  • •Ensure laterality is clearly documented as left hand to distinguish from M89.741 (right hand)
