Unspecified injury of right carotid artery, sequela

This code signifies a long-term complication or late effect resulting from an unspecified injury to the right carotid artery. This could include conditions such as chronic dissection, pseudoaneurysm, stenosis, or occlusion that developed as a consequence of a past traumatic event to the artery. The original injury itself is no longer acute.

Use this code when documentation clearly indicates a current condition or symptom directly attributable to a previous, unspecified injury of the right carotid artery. This applies when the acute phase of the initial injury has passed, and the patient is now presenting with a sequela. Supporting documentation should specify the link between the past injury and the current manifestation.

• Always sequence this sequela code first, followed by a code describing the specific nature of the sequela (e.g., I65.21 for occlusion and stenosis of right carotid artery).
• Ensure the documentation explicitly states "sequela" or "late effect" and links the current condition to a past injury of the right carotid artery.
• Do not use this code for acute injuries; instead, refer to the acute injury codes within the S15.0- category.
