Traum subrac hem w LOC of 1-5 hrs 59 min, init

This diagnosis code signifies a traumatic injury resulting in bleeding into the subarachnoid space of the brain. Specifically, it indicates that the patient experienced a loss of consciousness lasting between one hour and five hours and fifty-nine minutes due to this hemorrhage. This condition is typically a consequence of head trauma.

Apply this code for patients presenting with a subarachnoid hemorrhage directly attributable to an external force or injury, where the medical record clearly documents a period of unconsciousness within the specified timeframe. Documentation supporting its use includes physician notes detailing the mechanism of injury, neurological assessments, and the precise duration of altered mental status or loss of consciousness.

• Ensure the documentation explicitly states "traumatic" subarachnoid hemorrhage to differentiate from non-traumatic causes.
• Verify the exact duration of loss of consciousness; codes vary based on time intervals.
• This "A" suffix indicates an initial encounter for active treatment of the injury.
