D49.2

Billable

Neoplasm of unspecified behavior of bone, soft tissue, and skin

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

What This Code Means

A tumor or growth of unknown behavior found in bones, soft tissues (muscles, fat, connective tissue), or skin.

Coding Tips

  • Identify the specific anatomical site (e.g., bone of arm, subcutaneous tissue of leg) to use more specific D49.2 subcodes when available
  • Distinguish between benign lipomas or cysts and truly uncertain neoplasms through clinical and pathological correlation
