I25

Chronic ischemic heart disease

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 9 more specific codes instead:

  • I25.1 Atherosclerotic heart disease of native coronary artery (also a header)
  • I25.2 Old myocardial infarction
  • I25.3 Aneurysm of heart
  • I25.4 Coronary artery aneurysm and dissection (also a header)
  • I25.5 Ischemic cardiomyopathy
  • I25.6 Silent myocardial ischemia
  • I25.7 Atherosclerosis of coronary artery bypass graft(s) and coronary artery of transplanted heart with angina pectoris (also a header)
  • I25.8 Other forms of chronic ischemic heart disease (also a header)
  • I25.9 Chronic ischemic heart disease, unspecified

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.
