Hyperplasia of appendix

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

What This Code Means

The appendix has grown larger than normal due to an increase in tissue. This is a non-inflammatory enlargement of the appendix.

Coding Tips

  • •Distinguish from appendicitis (K37) which involves inflammation; K38.0 is hyperplasia without inflammation
  • •Document whether this is an incidental finding or symptomatic to support medical necessity
