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

This code signifies a traumatic bleeding into the subarachnoid space of the brain, resulting from an injury, where the patient experienced a loss of consciousness lasting between 31 and 59 minutes. This specific code is used for encounters following the initial treatment of the injury.

Apply this code for follow-up visits, rehabilitation encounters, or subsequent hospitalizations where the patient is still receiving care related to a traumatic subarachnoid hemorrhage with a documented loss of consciousness between 31 and 59 minutes. Documentation should clearly state the traumatic etiology, the specific duration of unconsciousness, and that this is not the initial encounter for the injury.

• Ensure documentation specifies "subsequent encounter" to differentiate from initial care.
• Verify the exact duration of loss of consciousness; codes vary by time intervals.
• Always code the underlying external cause of the injury (e.g., fall, motor vehicle accident) in addition to this diagnosis code.
