Open posterior occlusal relationship

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

What This Code Means

A dental condition where the back teeth don't meet properly when biting down, with a visible gap between the upper and lower teeth in the back of the mouth.

Coding Tips

  • •This is a specific type of open bite affecting only the posterior teeth; verify documentation specifies posterior location
  • •Distinguish from M26.220 (anterior open bite) by confirming the gap is in the back teeth only
