Adhesions and ankylosis of right temporomandibular joint

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

What This Code Means

A condition where the right jaw joint becomes stiff and immobile due to scar tissue formation or fusion of the joint surfaces, limiting jaw movement.

Coding Tips

  • •Distinguish between adhesions (scar tissue) and ankylosis (fusion); both are included in this code
  • •Document the degree of limitation in jaw opening and any functional impact on eating or speech
