Major osseous defect, unspecified site

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 at an unspecified location in the body, which may result from injury, disease, or surgical removal.

Coding Tips

  • Use this code only when the specific anatomical site of the osseous defect cannot be determined; always attempt to identify the specific site for more precise coding.
  • Document the underlying cause (trauma, infection, neoplasm removal) in the medical record to support medical necessity and potential treatment planning.
