Ankylosis, unspecified ankle

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

What This Code Means

A condition where the ankle joint becomes stiff and loses its ability to move freely, with the specific ankle (left or right) not specified.

Coding Tips

  • •Use this code only when the affected ankle cannot be determined from documentation; if laterality is known, use M24.671 or M24.672.
  • •Ankle ankylosis may result from previous fractures, arthritis, or infection; review clinical history for etiology.
