Cerebral infarction due to embolism of right carotid artery

This code signifies an ischemic stroke resulting from a blockage in the right carotid artery caused by an embolus (a traveling clot or other material). This type of infarction leads to tissue death in the brain due to a lack of blood supply.

Apply this code when documentation clearly states a cerebral infarction (ischemic stroke) and specifies the etiology as an embolism affecting the right carotid artery. Supporting documentation would include imaging reports (e.g., MRI, CT scan) confirming infarction and physician notes detailing the embolic nature and specific vessel involvement.

• Ensure documentation differentiates between thrombosis and embolism; this code is specific to embolic etiology.
• Verify laterality (right carotid artery) is explicitly stated; do not assume.
• Sequence this code as the principal diagnosis if it is the primary reason for the encounter, followed by any associated conditions.
