Inj r int carotid, intcr w LOC of unsp duration, sequela

This code signifies a long-term effect or complication arising from a past injury to the intracranial portion of the right internal carotid artery, which was associated with an unquantified period of unconsciousness. It indicates that the initial injury has resolved, but the patient continues to experience residual symptoms or conditions directly attributable to that specific trauma.

This code is appropriate for documenting a patient presenting with chronic neurological deficits, cognitive impairments, or other lasting sequelae directly linked to a previously sustained intracranial right internal carotid artery injury with associated loss of consciousness. Documentation should clearly state the prior injury and the current, ongoing symptoms as a direct consequence of that injury.

• Always use a sequela code when the acute phase of the injury has passed and the patient is being treated for the residual effects.
• Ensure documentation specifies the right internal carotid artery and the intracranial portion, as well as the history of loss of consciousness.
• Do not use this code for the initial acute injury; instead, use the acute injury code with the appropriate seventh character.
