Traum subdr hem w LOC of 1-5 hrs 59 min, init

This code signifies a traumatic subdural hemorrhage, which is bleeding between the dura mater and the arachnoid membrane, resulting from an injury. The patient experienced a loss of consciousness lasting between one hour and five hours and fifty-nine minutes due to this hemorrhage. This code specifically applies to the initial treatment or encounter for this acute injury.

Use this code for patients presenting with a newly diagnosed traumatic subdural hemorrhage where the documented loss of consciousness falls within the specified timeframe. Supporting documentation must clearly state the cause as traumatic and precisely indicate the duration of unconsciousness. This code is appropriate for the initial hospital admission or emergency department visit for the injury.

• Ensure the medical record explicitly states the traumatic etiology of the subdural hemorrhage, not spontaneous.
• Verify the exact duration of loss of consciousness; codes vary based on time intervals (e.g., less than 1 hour, 6-24 hours).
• This "initial encounter" character (A) is used as long as the patient is receiving active treatment for the injury.
