Esophagitis

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 3 more specific codes instead:

  • K20.0 Eosinophilic esophagitis
  • K20.8 Other esophagitis (also a header)
  • K20.9 Esophagitis, unspecified (also a header)

What has happened to this code

Every change the publisher made, from 2007 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

  1. FY2007 Added to the draft code set draft Esophagitis
  2. FY2010 Removed from the draft draft
  3. FY2012 Returned to the draft draft
