Cerebrovascular diseases (I60-I69) ICD-10-CM
The I60–I69 section covers cerebrovascular diseases with 505 ICD-10-CM diagnosis codes, of which 410 are billable in fiscal year 2027. The section is organized into the 9 code ranges listed below.
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
- code to identify presence of:
- alcohol abuse and dependence F10
- exposure to environmental tobacco smoke Z77.22
- history of tobacco dependence Z87.891
- hypertension I10 I1A
- occupational exposure to environmental tobacco smoke Z57.31
- tobacco dependence F17
- tobacco use Z72.0
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- traumatic intracranial hemorrhage S06

About the I60–I69 Code Range
These conditions involve bleeding within the skull, disrupted blood flow in the brain, narrowed or blocked arteries, and lasting effects of cerebrovascular disease.
I60, I61, and I62 separate types of bleeding not caused by injury. Their subdivisions identify the source artery, the location of bleeding, or another specified type. I63 describes cerebral infarction, an area of brain tissue that dies from insufficient blood flow. Its subdivisions distinguish the affected blood vessels and whether the cause is a clot, an embolism, or another blockage.
I65 and I66 describe narrowed or blocked arteries without cerebral infarction. They separate precerebral from cerebral arteries, then identify the artery. I67 groups other cerebrovascular diseases, while I68 identifies cerebrovascular disorders in diseases classified elsewhere. I69 organizes lasting effects by the type of cerebrovascular disease that preceded them.
