Nontraumatic intracerebral hemorrhage (I61) ICD-10-CM
The I61 code range covers nontraumatic intracerebral hemorrhage with 10 ICD-10-CM diagnosis codes. 9 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
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, if known, to indicate National Institutes of Health Stroke Scale NIHSS score R29.7
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the I61 range.
Basal Ganglia Hemorrhage
Bleeding within the subcortical regions of cerebral hemispheres (BASAL GANGLIA). It is often associated with HYPERTENSION or ARTERIOVENOUS MALFORMATIONS. Clinical manifestations may include HEADACHE; DYSKINESIAS; and HEMIPARESIS.
Cerebral Amyloid Angiopathy, Familial
A familial disorder marked by AMYLOID deposits in the walls of small and medium sized blood vessels of CEREBRAL CORTEX and MENINGES.
Cerebral Hemorrhage
Bleeding into one or both CEREBRAL HEMISPHERES including the BASAL GANGLIA and the CEREBRAL CORTEX. It is often associated with HYPERTENSION and CRANIOCEREBRAL TRAUMA.
Cerebral Hemorrhage, Traumatic
Bleeding into one or both CEREBRAL HEMISPHERES due to TRAUMA. Hemorrhage may involve any part of the CEREBRAL CORTEX and the BASAL GANGLIA. Depending on the severity of bleeding, clinical features may include SEIZURES; APHASIA; VISION DISORDERS; MOVEMENT DISORDERS; PARALYSIS; and COMA.
Intracranial Hemorrhage, Hypertensive
Bleeding within the SKULL that is caused by systemic HYPERTENSION, usually in association with INTRACRANIAL ARTERIOSCLEROSIS. Hypertensive hemorrhages are most frequent in the BASAL GANGLIA; CEREBELLUM; PONS; and THALAMUS; but may also involve the CEREBRAL CORTEX, subcortical white matter, and other brain structures.
About the I61 Code Range
ICD-10 codes I61 and its subcategories are used to identify and classify various types of nontraumatic intracerebral hemorrhages, or bleeding within the brain that occurs without injury. These codes specify the precise brain location of the hemorrhage, aiding accurate diagnosis and treatment documentation.
The general code I61 covers all nontraumatic intracerebral hemorrhages. More detailed codes include I61.0 for hemorrhages in the deep, subcortical areas of the brain hemisphere, also known as basal ganglia or putamen hemorrhages; I61.1 and I61.2 for hemorrhages in cortical or unspecified parts of the hemisphere commonly called lobar hemorrhages. Codes I61.3 and I61.4 are for brainstem and cerebellar bleeds, respectively, terms sometimes encountered as brain stem or cerebellar hematoma. I61.5 describes bleeding into the brain’s ventricular system, while I61.6 denotes multiple localized intracerebral hemorrhages. Other specific patterns of hemorrhage, such as hemorrhagic infarctions or thalamic hemorrhages, fall under I61.8. When the precise location isn’t documented, I61.9 is used. These ICD-10 codes enable clinicians and coders to distinguish the site and nature of spontaneous brain bleeds accurately, essential for proper care and epidemiological tracking.
Questions About This Page
How many billable codes are in the I61 range?
Of the 10 codes in this range, 9 are billable and valid for claim submission from October 1, 2025 through September 30, 2026. Category header codes group them but cannot be reported on claims.
What does the I61 range classify?
The range classifies nontraumatic intracerebral hemorrhage. Each code links to its own reference page with billing status, MS-DRG grouping, coding notes, and clinical information.
