Gastric intestinal metaplasia with low 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 early-stage abnormal cell growth that shows mild dysplasia.

Coding Tips

  • •Low-grade dysplasia indicates precancerous changes; ensure the pathology report specifically documents 'low-grade dysplasia' to distinguish from high-grade
  • •Document the site of dysplasia when possible, as this may affect surveillance and treatment recommendations
