Billable

Adhesions and ankylosis of bilateral temporomandibular joint

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

What This Code Means

Stiffness and fusion of the jaw joints on both sides, where the joints become stuck and cannot move freely.

Coding Tips

  • •This code specifies bilateral involvement; do not use if only one side is affected
  • •Adhesions and ankylosis represent joint stiffness/fusion; ensure documentation supports this severity level rather than simple pain
