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

This code signifies a traumatic bleeding into the subarachnoid space of the brain, resulting from an injury, where the patient experienced a brief period of unconsciousness lasting 30 minutes or less. This specific code is for a subsequent encounter, meaning the patient is receiving follow-up care for this previously diagnosed condition.

Apply this code when a patient is seen for ongoing management, monitoring, or treatment of a traumatic subarachnoid hemorrhage that occurred previously. Documentation should clearly state the traumatic etiology, the history of loss of consciousness (LOC) for 30 minutes or less, and indicate that this is not the initial presentation for the condition.

• Ensure documentation specifies "traumatic" subarachnoid hemorrhage to differentiate from non-traumatic causes.
• Verify the duration of loss of consciousness is explicitly stated as 30 minutes or less; otherwise, a different code for LOC duration would be appropriate.
• Confirm this is a subsequent encounter; for the initial encounter, a code with the "A" seventh character would be used.
