Nontraumatic intracerebral hemorrhage in brain stem

This code signifies a spontaneous (nontraumatic) bleeding event occurring within the brainstem. This type of hemorrhage is often severe due to the critical functions controlled by the brainstem, including consciousness, breathing, and heart rate. It is distinct from hemorrhages caused by external injury.

Use this code for patients diagnosed with an intracerebral hemorrhage confirmed to be located specifically within the brainstem, and where trauma has been ruled out as the cause. Documentation should clearly state "nontraumatic brainstem hemorrhage" or similar phrasing, often supported by imaging reports (e.g., CT, MRI).

• Ensure documentation explicitly states "nontraumatic" and "brainstem" to support this specific code.
• Distinguish from traumatic intracerebral hemorrhage (S06.3-) and other intracranial hemorrhages (e.g., subarachnoid, subdural).
• Code any associated neurological deficits or sequelae separately, following the acute hemorrhage code.
