Traum subdr hem w LOC >24 hr w ret consc lev, sequela

This code signifies a chronic or late effect of a traumatic subdural hemorrhage where the patient experienced a loss of consciousness exceeding 24 hours. Crucially, the patient's conscious level subsequently returned to their baseline state prior to the injury. This represents the long-term consequences or residual effects of such an event.

Apply this code when documenting the sequela of a past traumatic subdural hemorrhage with prolonged loss of consciousness (over 24 hours) that has since resolved to the patient's pre-injury conscious level. Documentation should clearly state the history of the traumatic subdural hemorrhage, the duration of unconsciousness, and the current neurological status indicating a return to baseline consciousness.

• This "S" seventh character indicates a sequela, meaning it should be used for complications or conditions arising as a direct result of the initial injury, after the acute phase has passed.
• Ensure documentation explicitly states "loss of consciousness greater than 24 hours" and "return to pre-existing conscious level" to support this specific code.
• Do not use this code for the acute phase of the injury; it is strictly for the long-term effects.
