Billable

Flail joint, unspecified ankle and foot

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

What This Code Means

A condition where an ankle and foot joint becomes unstable and moves excessively in multiple directions, but the specific ankle (right or left) is not specified.

Coding Tips

  • Use only when laterality cannot be determined; query provider for clarification if possible
  • Bilateral ankle flail should be coded separately for each side rather than using this unspecified code
