Traum subdr hem w LOC w dth d/t brain inj bef reg consc,init

This code signifies a subdural hemorrhage resulting from trauma, where the patient experienced a loss of consciousness of any duration and subsequently died due to the brain injury before regaining consciousness. It specifically captures the initial encounter for this severe and ultimately fatal traumatic brain injury.

Apply this code when documentation clearly indicates a traumatic subdural hemorrhage, a period of unconsciousness, and the patient's death directly attributed to the brain injury prior to awakening. This code is appropriate for the initial hospital admission or encounter where this sequence of events is established.

• Ensure documentation explicitly states "death due to brain injury before regaining consciousness" to support this specific seventh character.
• Do not use this code if the patient regained consciousness, even briefly, before death.
• Sequence this code as the principal diagnosis if it is the primary reason for the encounter and subsequent death.
