ICD-10 Code I61.0 – Nontraumatic intracerebral hemorrhage in hemisphere, subcortical (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I61.0 – Nontraumatic intracerebral hemorrhage in hemisphere, subcortical
What it is
This code identifies a spontaneous bleed within the brain tissue, located in a cerebral hemisphere and involving the subcortical region. It is used when the hemorrhage is not caused by trauma.
Clinical signs
Clinical features vary; refer to documentation. Common findings include sudden neurologic deficit such as weakness, speech difficulty, altered consciousness, or headache, with imaging confirming an intracerebral hemorrhage in the specified location.
When to use this code
Use I61.0 when the provider documents a nontraumatic intracerebral hemorrhage in a hemisphere’s subcortical area, and the record supports the anatomic site. This is appropriate for confirmed spontaneous brain hemorrhage on CT or MRI. If the note only says “intracerebral hemorrhage” without location, check documentation.
Do not use for
Do not use this code for traumatic intracranial bleeding or for hemorrhage in a different brain location, such as cerebellum or brainstem. Check documentation if the record describes subarachnoid, subdural, or epidural bleeding instead.
Coding tip
Match the code to the exact hemorrhage site and confirm it is nontraumatic before assigning I61.0.
