R79.8

Other specified abnormal findings of blood chemistry

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 4 more specific codes instead:

  • R79.81 Abnormal blood-gas level
  • R79.82 Elevated C-reactive protein (CRP)
  • R79.83 Abnormal findings of blood amino-acid level
  • R79.89 Other specified abnormal findings of blood chemistry

What has happened to this code

Every change the publisher made, from 2012 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.

Official coding rules

Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.
