I22

Subsequent ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction

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 5 more specific codes instead:

  • I22.0 Subsequent ST elevation (STEMI) myocardial infarction of anterior wall
  • I22.1 Subsequent ST elevation (STEMI) myocardial infarction of inferior wall
  • I22.2 Subsequent non-ST elevation (NSTEMI) myocardial infarction
  • I22.8 Subsequent ST elevation (STEMI) myocardial infarction of other sites
  • I22.9 Subsequent ST elevation (STEMI) myocardial infarction of unspecified site

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.
