Gastro-esophageal reflux disease with esophagitis, without bleeding

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

What This Code Means

Acid reflux disease causing inflammation of the esophagus, without bleeding.

Coding Tips

  • •This code requires documentation of both GERD and esophagitis; reflux alone without esophagitis uses K21.9
  • •Verify that esophageal inflammation is documented, not just reflux symptoms
