0.000What This Code Means
Bleeding within the brain tissue in the deeper structures of the cerebral hemisphere, not caused by trauma.
Coding Tips
- •Subcortical location refers to deep brain structures; ensure documentation specifies this location versus cortical
- •Confirm the hemisphere affected if documented; if bilateral or unspecified, use I61.2
Clinical Significance
Nontraumatic intracerebral hemorrhage in the subcortical region of the hemisphere represents bleeding in the deep brain structures including the basal ganglia, thalamus, and internal capsule. This is a major acute cerebrovascular event with significant impact on patient functional outcomes and mortality. Accurate coding is essential for risk adjustment as it reflects high-acuity care requirements.
Documentation Requirements
- ✓Imaging confirmation (CT or MRI) specifying subcortical location of hemorrhage
- ✓Documentation of nontraumatic etiology
- ✓Identification of the affected hemisphere (right or left) when known
- ✓Neurological examination findings including motor and sensory deficits
- ✓Clinical presentation including onset, symptoms, and severity
- ✓Treatment plan and neurosurgical evaluation
Commonly Confused Codes
I61.1 — Cortical hemorrhage; bleeding in the outer surface of the brain rather than deep structuresI61.2 — Unspecified hemisphere hemorrhage; use only when subcortical vs. cortical location is not documentedI61.9 — Unspecified intracerebral hemorrhage; less specific, does not identify locationI62.00 — Subdural hemorrhage; bleeding between the brain surface and dural membrane, not within brain tissue
