I63

Cerebral 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 9 more specific codes instead:

  • I63.0 Cerebral infarction due to thrombosis of precerebral arteries (also a header)
  • I63.1 Cerebral infarction due to embolism of precerebral arteries (also a header)
  • I63.2 Cerebral infarction due to unspecified occlusion or stenosis of precerebral arteries (also a header)
  • I63.3 Cerebral infarction due to thrombosis of cerebral arteries (also a header)
  • I63.4 Cerebral infarction due to embolism of cerebral arteries (also a header)
  • I63.5 Cerebral infarction due to unspecified occlusion or stenosis of cerebral arteries (also a header)
  • I63.6 Cerebral infarction due to cerebral venous thrombosis, nonpyogenic
  • I63.8 Other cerebral infarction (also a header)
  • I63.9 Cerebral infarction, 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.

  1. FY2012 Added to the draft code set draft Cerebral infarction

How CDC's index refers to this code

Wording from the official alphabetic index. Much of it appears nowhere in the code description, which is why a search for the everyday phrase so often finds nothing.
