Cereb infrc due to embolism of left middle cerebral artery

This code signifies an ischemic stroke resulting from an embolic occlusion specifically affecting the left middle cerebral artery. This type of stroke occurs when a blood clot, originating elsewhere in the body, travels to and blocks this particular artery in the brain, leading to tissue damage.

This code is appropriate for patients diagnosed with an acute cerebral infarction confirmed to be embolic in nature and localized to the left middle cerebral artery territory. Documentation should clearly state the embolic etiology and the specific cerebral artery involved, often supported by imaging studies (e.g., MRI, CT angiography).

• Ensure documentation specifies "left" middle cerebral artery; laterality is crucial for accurate coding.
• Distinguish from thrombotic strokes (I63.3x) or strokes of unspecified etiology (I63.9).
• Always sequence the acute stroke code first, followed by any associated conditions or sequelae.
