Inj r int carotid, intcr w LOC of 1-5 hrs 59 min, sequela

This code signifies a sequela of a traumatic injury to the intracranial segment of the right internal carotid artery, specifically when the initial injury resulted in a loss of consciousness lasting between one and nearly six hours. This indicates a persistent or late effect stemming from the original vascular trauma within the brain.

Apply this code for patients presenting with long-term neurological deficits or complications directly attributable to a past traumatic right intracranial internal carotid artery injury. Documentation must clearly state the original injury, the specific artery involved, the intracranial location, and the duration of the associated loss of consciousness.

• Ensure documentation explicitly links the current condition to the sequela of the original injury, not the acute injury itself.
• Verify the laterality (right) and the specific intracranial portion of the internal carotid artery are clearly documented.
• Confirm the initial loss of consciousness duration falls precisely within the 1 hour to 5 hours 59 minutes timeframe for accurate code assignment.
