Injury of r int carotid, intcr w LOC of 31-59 min, sequela

This code signifies a delayed complication or sequela resulting from a traumatic injury to the intracranial segment of the right internal carotid artery, not otherwise specified. The initial injury involved a loss of consciousness lasting between 31 and 59 minutes. This code is used to report the long-term effects or conditions arising from that original trauma.

Apply this code when documenting a patient presenting with a current condition directly attributable to a past intracranial right internal carotid artery injury, where the initial event included a moderate period of unconsciousness. Documentation must clearly link the current sequela to the specified past trauma and confirm the duration of the initial loss of consciousness.

• Always assign a sequela code (S06.812S) when the patient is seen for a late effect of the injury, not the acute injury itself.
• Ensure the medical record explicitly states the laterality (right) and the intracranial portion of the carotid artery.
• Verify the exact duration of the initial loss of consciousness (31-59 minutes) is documented to support this specific code.
