Gastric intestinal metaplasia with high grade dysplasia

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

What This Code Means

The stomach lining has changed to resemble intestinal tissue with more advanced abnormal cell growth that shows severe dysplasia.

Coding Tips

  • •High-grade dysplasia is a significant precancerous finding; verify pathology confirmation and ensure this is not miscoded as low-grade dysplasia
  • •This finding typically warrants closer follow-up and possible intervention; coordinate with gastroenterology for appropriate management documentation
