Nontraumatic intracerebral hemorrhage (I61)

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.

Instructional Notations

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.

  • sequelae of intracerebral hemorrhage I69.1

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

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.
