Traum subdr hem w LOC of unsp duration, init

This code signifies a traumatic subdural hemorrhage where the patient experienced a loss of consciousness for an unknown duration, and this is the initial treatment encounter for the injury. A subdural hemorrhage involves bleeding between the dura mater and the arachnoid mater, typically caused by head trauma.

Apply this code when documentation confirms a traumatic subdural hemorrhage and a period of unconsciousness, but the specific duration of the loss of consciousness is not recorded. This code is appropriate for the initial hospital admission or encounter for the injury.

• Ensure documentation explicitly states "traumatic" and "loss of consciousness" without specifying the duration.
• Do not use this code if the duration of loss of consciousness is documented (e.g., less than 30 minutes, 30 minutes or more).
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
