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 7 more specific codes instead:

  • G45.0 Vertebro-basilar artery syndrome
  • G45.1 Carotid artery syndrome (hemispheric)
  • G45.2 Multiple and bilateral precerebral artery syndromes
  • G45.3 Amaurosis fugax
  • G45.4 Transient global amnesia
  • G45.8 Other transient cerebral ischemic attacks and related syndromes
  • G45.9 Transient cerebral ischemic attack, 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.
