Traum subrac hem w LOC of 30 minutes or less, init

This code signifies bleeding into the subarachnoid space of the brain resulting from trauma, where the patient experienced a brief period of unconsciousness lasting 30 minutes or less. It indicates an acute injury requiring initial medical attention.

Apply this code for patients presenting with a traumatic subarachnoid hemorrhage confirmed by imaging (e.g., CT scan) and documented loss of consciousness not exceeding 30 minutes. This code is appropriate for the initial visit or encounter for this specific injury.

• Ensure documentation clearly specifies "traumatic" etiology and the duration of loss of consciousness.
• Do not use this code for non-traumatic (e.g., aneurysmal) subarachnoid hemorrhage.
• Verify the "A" seventh character for initial encounter; subsequent care would use "D" or "S."
