Traum subrac hem w loss of consciousness of 31-59 min, init

This code signifies a traumatic injury resulting in bleeding into the subarachnoid space of the brain, specifically when the patient experienced a loss of consciousness lasting between 31 and 59 minutes. This condition is a serious form of intracranial hemorrhage, often associated with significant head trauma.

Apply this code for patients presenting with a newly diagnosed traumatic subarachnoid hemorrhage where the documented duration of unconsciousness falls within the 31-59 minute range. Documentation must clearly specify the traumatic etiology and the precise duration of the loss of consciousness.

• Always verify the cause of the subarachnoid hemorrhage; this code is specific to traumatic origin.
• Carefully review the medical record for the exact duration of loss of consciousness to ensure the correct 7th character is selected.
• This "initial encounter" character (A) is used for the entire period a patient is receiving active treatment for the injury.
