Loose body in unspecified joint

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

What This Code Means

A fragment of bone, cartilage, or other tissue that has become detached and is floating freely inside a joint, but the specific joint location is not specified.

Coding Tips

  • •Always attempt to identify the specific joint involved and use a more specific code (M24.01-M24.09) rather than the unspecified code
  • •Document whether the loose body is causing mechanical symptoms like locking or catching
