Q75.3

Billable

Macrocephaly

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

What This Code Means

A birth defect where the head is abnormally large due to increased skull size, often related to increased fluid or brain tissue.

Coding Tips

  • •Distinguish between macrocephaly (enlarged head) and hydrocephalus (fluid accumulation); code both if present
  • •Document the underlying cause if identified, as this may affect treatment planning
