Cerebral infrc due to thombos unsp anterior cerebral artery

This code signifies a cerebral infarction (ischemic stroke) caused by a blockage from a thrombus (blood clot) within an anterior cerebral artery. The specific anterior cerebral artery (e.g., right or left) is not documented or is unknown. This results in tissue death in the brain region supplied by that artery.

Use this code when documentation clearly states a cerebral infarction due to thrombosis of an anterior cerebral artery, but the laterality (right or left) is not specified. This typically occurs in acute stroke presentations where imaging confirms an anterior cerebral artery occlusion and infarction, but the precise vessel is not detailed.

• Ensure documentation specifies "thrombosis" as the cause, not embolism or unspecified occlusion.
• If laterality (right or left) is documented, use the more specific codes I63.321 or I63.322.
• Always sequence the stroke code first, followed by any associated conditions or sequelae.
