Excessive horizontal overlap

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

What This Code Means

A dental misalignment where the upper front teeth overlap the lower front teeth too much horizontally, creating an excessive horizontal overlap.

Coding Tips

  • •Document the severity if mentioned (mild, moderate, severe) as this may affect treatment planning
  • •Ensure this is not confused with vertical overlap (overbite); this code specifically addresses horizontal overlap
