Unsp focal TBI w LOC >24 hr w/o ret consc w surv, init

This diagnosis code signifies a traumatic brain injury (TBI) where the specific type of focal injury (e.g., contusion, laceration) is not documented, and the patient experienced a coma lasting longer than 24 hours. Crucially, the patient has not regained their baseline level of consciousness, and they survived the initial injury.

Apply this code for patients presenting with an acute, unspecified focal TBI who have a documented history of prolonged loss of consciousness exceeding 24 hours, with persistent altered mental status. Documentation must clearly state the duration of unconsciousness and the patient's current neurological state, indicating no return to pre-injury consciousness.

• Ensure documentation explicitly states "unspecified focal" TBI and "loss of consciousness greater than 24 hours without return to pre-existing conscious level."
• Verify that the encounter is the "initial encounter" for the injury. Subsequent care would require a different 7th character.
• Distinguish from codes for concussions or TBIs with shorter durations of unconsciousness or full recovery of consciousness.
