Major osseous defect, right humerus

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 bone structure of the right upper arm bone (humerus), which may result from fracture complications, infection, or surgical intervention.

Coding Tips

  • •Distinguish between defects of the humerus and those of the shoulder region; humerus codes are more specific to the arm bone itself.
  • •Document whether the defect involves the proximal, middle, or distal portion of the humerus if available, as this affects functional impact.
