Unsp intcrn injury w LOC >24 hr w/o ret consc w surv, sqla

This code signifies a severe, unspecified traumatic brain injury where the patient experienced a coma or vegetative state lasting over 24 hours, and has not regained their baseline cognitive function. The patient has survived the initial injury, but is left with lasting neurological deficits.

Apply this code for patients who have sustained an intracranial injury of unknown specific type, resulting in prolonged loss of consciousness (greater than 24 hours), and who, upon survival, exhibit persistent impairment in their conscious level compared to their pre-injury state. Documentation should clearly state the duration of unconsciousness and the ongoing neurological sequelae.

• This code is for sequela, meaning it should be used for encounters after the acute phase of the injury.
• Ensure documentation specifies "unspecified" intracranial injury and "loss of consciousness greater than 24 hours without return to pre-existing conscious level."
• Always sequence this code after any codes identifying the specific nature of the sequela (e.g., cognitive deficits, motor impairments).
