ICD-10-CM › I00-I99 › I60-I69 › I63 Cerebral infarction › I63.9
Cerebral infarction, unspecified
ValidICD-10-CM diagnosis code.
Valid for claims with a date of service in the current code year.
What has happened to this code
Every change the publisher made, from 2007 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.
- FY2007 Added to the draft code set draft Cerebral infarction, unspecified
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.

- neonatal cerebral infarction (P91.82-)
Excludes2 - not included here
- chronic, without residual deficits (sequelae) (Z86.73)

Use additional code
- code, if applicable, to identify status post administration of tPA (rtPA) in a different facility within the last 24 hours prior to admission to current facility (Z92.82)
- code, if known, to indicate National Institutes of Health Stroke Scale (NIHSS) score (R29.7-)
