Traum subrac hem w/o loss of consciousness, init

This code signifies bleeding into the subarachnoid space of the brain, caused by a traumatic injury, where the patient did not experience a loss of consciousness. This condition is a type of intracranial hemorrhage resulting from external force or trauma.

Apply this code when documentation clearly states a traumatic subarachnoid hemorrhage occurred without any reported loss of consciousness, and this is the initial encounter for treatment of this specific injury. Supporting documentation includes imaging reports (e.g., CT scan) confirming subarachnoid blood and physician notes detailing the traumatic etiology and mental status upon presentation.

• Ensure documentation explicitly states "without loss of consciousness" to differentiate from other subarachnoid hemorrhage codes.
• Verify the "initial encounter" status; subsequent care for the same injury will require a different seventh character.
• Always code the underlying external cause of the trauma (e.g., fall, motor vehicle accident) in addition to this diagnosis.
