S06.6XAA
ICD-10-CMTraumatic subarachnoid hemorrhage with loss of consciousness status unknown, initial encounter
This code signifies bleeding into the subarachnoid space of the brain resulting from a traumatic injury, where the patient's level of consciousness immediately following the trauma is not documented. This condition is a serious form of intracranial hemorrhage, often associated with significant head trauma.
Apply this code when documentation confirms a traumatic subarachnoid hemorrhage and explicitly states "loss of consciousness status unknown" or similar phrasing indicating the duration or presence of LOC cannot be determined. This code is appropriate for the initial encounter for treatment of the acute injury.
