Epidural hemorrhage w LOC >24 hr w/o ret consc w surv, init

This code signifies an epidural hemorrhage, a type of intracranial bleed occurring between the dura mater and the skull, that results in a prolonged coma. The patient's unconscious state persists for over 24 hours and they do not regain their baseline level of consciousness, though they survive the initial event. This indicates a severe traumatic brain injury with significant neurological impact.

This code is appropriate for initial encounters where documentation confirms an epidural hemorrhage and a Glasgow Coma Scale (GCS) score or similar assessment indicates a loss of consciousness exceeding 24 hours, with no return to pre-injury cognitive function. The patient must be alive at the time of coding for this specific "surviving" code.

• Ensure documentation explicitly states "loss of consciousness greater than 24 hours" and "without return to pre-existing conscious level."
• Verify the patient's survival status; different codes apply if the patient does not survive.
• Distinguish from other intracranial hemorrhages (e.g., subdural, subarachnoid) based on anatomical location.
