Diffuse TBI w LOC w death due to brain injury bf consc, init

This code signifies a severe, widespread traumatic brain injury that results in a period of unconsciousness of any length. Crucially, the patient's death is directly attributable to the brain injury and occurs before they regain consciousness.

This code is appropriate for initial encounters where a patient sustains a diffuse TBI, experiences loss of consciousness, and subsequently dies from the brain injury itself, prior to awakening. Documentation must clearly link the cause of death to the TBI and confirm the absence of regained consciousness.

• Ensure documentation explicitly states "death due to brain injury prior to regaining consciousness" to justify this specific seventh character.
• Do not use this code if the patient regains consciousness, even briefly, before succumbing to the injury.
• Always sequence this code as the principal diagnosis when it meets the criteria for the reason for admission.
