Cerebral infrc due to embolism of unsp ant cerebral artery

This code signifies a stroke resulting from an embolic blockage within an anterior cerebral artery, where the specific anterior cerebral artery (e.g., right or left) is not documented. An embolus, often originating from the heart or carotid arteries, travels to and obstructs blood flow in the brain, leading to tissue death.

Apply this code when documentation confirms a cerebral infarction caused by an embolism affecting an anterior cerebral artery, but the laterality (right or left) is not specified. This is appropriate when imaging (e.g., MRI, CT) and clinical findings support an embolic stroke in the anterior cerebral artery territory without further anatomical detail.

• Ensure documentation explicitly states "embolism" as the cause of the infarction.
• Only use this code when the specific anterior cerebral artery is truly unspecified; otherwise, use a more specific code for right or left.
• Always sequence the stroke code first, followed by any associated conditions like atrial fibrillation (I48.-) if it's the source of the embolus.
