Inj r int crtd, intcrn portion, NEC LOC status unknown, sqla

This code signifies a past injury to the intracranial segment of the right internal carotid artery, where the patient's consciousness status at the time of the original injury is unknown. The "sequela" designation indicates that this code is used to report a current condition or complication resulting from that previous injury, rather than the acute injury itself.

Apply this code when documenting a current neurological deficit, vascular complication, or other long-term effect directly attributable to a prior intracranial right internal carotid artery injury where the initial loss of consciousness was not documented. Supporting documentation must clearly link the current condition to the old injury and specify the right side and intracranial portion of the artery.

• Always ensure the documentation explicitly states "sequela" or clearly indicates a chronic condition resulting from a past injury.
• Distinguish carefully between acute injury codes and sequela codes; this code is for the aftermath, not the initial event.
• Verify laterality (right) and anatomical site (intracranial portion) are clearly documented to support this specific code.
