Ankylosis, unspecified hip

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

What This Code Means

A condition where the hip joint becomes stiff and loses its ability to move freely, with the specific side not specified.

Coding Tips

  • •Use this code only when the affected hip (left or right) is not documented; if laterality is specified, use M24.651 or M24.652 instead.
  • •Ankylosis often results from severe arthritis, trauma, or previous surgery; review clinical documentation for the underlying cause.
