Billable

Ankylosis, unspecified wrist

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

What This Code Means

A condition where a wrist joint becomes stiff and loses its ability to move due to abnormal fusion, but the specific side is not identified.

Coding Tips

  • •This is a less specific code; attempt to obtain laterality information from imaging reports or clinical documentation
  • •If bilateral ankylosis exists, code both M24.631 and M24.632 instead of using the unspecified code
