What This Code Means

Bleeding within the brain tissue in the outer layer of the cerebral hemisphere, not caused by trauma.

Coding Tips

•Cortical hemorrhage involves the brain's outer surface; distinguish from subcortical (I61.0) and unspecified (I61.2)
•Document which hemisphere is affected when possible for more specific coding

Clinical Significance

Nontraumatic intracerebral hemorrhage in the cortical (outer surface) region of the hemisphere is a significant cerebrovascular event. Cortical hemorrhages may be associated with cerebral amyloid angiopathy, particularly in elderly patients, and carry implications for recurrence risk and anticoagulation decisions. This diagnosis reflects a high-acuity condition requiring neurosurgical evaluation and intensive monitoring.

Documentation Requirements

✓Imaging confirmation (CT or MRI) specifying cortical location of hemorrhage
✓Documentation of nontraumatic etiology
✓Hemisphere laterality (right or left) when available
✓Clinical presentation including headache, seizures, or focal neurological deficits
✓Evaluation for underlying causes such as cerebral amyloid angiopathy or vascular malformations
✓Treatment plan and follow-up strategy

Commonly Confused Codes

I61.0 — Subcortical hemorrhage; bleeding in deep brain structures rather than the cortical surface I61.2 — Unspecified hemisphere hemorrhage; use when cortical vs. subcortical is not documented I62.00 — Subdural hemorrhage; bleeding is outside the brain parenchyma, beneath the dura S06.36 — Traumatic hemorrhage of cerebrum; use when hemorrhage is caused by trauma
