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 2026. 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
ICD-10 codes I60 through I69 cover cerebrovascular diseases, which involve conditions affecting blood flow and bleeding in the brain. These codes specify types of strokes such as hemorrhages, infarctions, arterial occlusions, and their long-term effects or sequelae.
The range starts with subarachnoid hemorrhages (I60) caused by nontraumatic bleeding around the brain, including specific sites like the carotid, middle cerebral, or basilar arteries, often linked to ruptured aneurysms known as "berry aneurysms." For example, I60.00 refers to nontraumatic subarachnoid hemorrhage from unspecified carotid siphon, also called ruptured internal carotid bifurcation aneurysm. Nontraumatic intracerebral hemorrhages (I61) include bleeding within brain tissue, such as basal ganglia or cerebellar hemorrhage. Other nontraumatic intracranial hemorrhages (I62) cover subdural or extradural bleeds not caused by trauma. Cerebral infarctions (I63) specify types of ischemic strokes due to thrombosis or embolism of cerebral or precerebral arteries, distinguished by vessel location such as vertebral or carotid arteries. Occlusions and stenoses (I65-I66) describe artery narrowing without resulting in infarction, aiding in identifying risk or symptomatic cerebrovascular compromise. This chapter also includes other cerebrovascular diseases (I67) like cerebral aneurysms and Moyamoya disease, as well as thrombosis of cerebral veins (I67.6). Finally, sequelae codes (I69) document lasting complications such as cognitive or motor deficits following strokes or hemorrhages, enhancing clinical tracking of stroke recovery stages and residual impairments. Using synonyms like "subarachnoid hemorrhage," "cerebral infarction," or "cerebral aneurysm" guides coders in precise identification of conditions within this comprehensive range.
