Traum subdr hem w LOC >24 hr w/o ret consc w surv, subs

This code signifies a traumatic subdural hemorrhage where the patient experienced a prolonged loss of consciousness exceeding 24 hours and did not regain their baseline neurological status. This specific code is used for a subsequent encounter, indicating ongoing care for the sequelae of the initial injury.

Apply this code for follow-up visits or hospitalizations when a patient is still recovering from a traumatic subdural hemorrhage that resulted in a coma lasting over 24 hours and they have not returned to their pre-injury level of consciousness. Documentation must clearly state the duration of unconsciousness, the lack of return to baseline, and that this is not the initial treatment encounter.

• Ensure documentation specifies "subsequent encounter" to differentiate from initial care.
• Verify the duration of loss of consciousness is explicitly stated as greater than 24 hours.
• Confirm the patient has not returned to their pre-existing conscious level; if they have, a different code would be appropriate.
