Maxillary hypoplasia

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

What This Code Means

The upper jaw (maxilla) is abnormally small or underdeveloped, which can affect bite alignment and facial structure.

Coding Tips

  • •Ensure documentation clearly indicates underdevelopment of the maxilla rather than other jaw abnormalities
  • •This condition may be associated with other craniofacial syndromes; review for additional diagnoses
