Epidural hemorrhage w LOC of 6 hours to 24 hours, init

This diagnosis code signifies an epidural hemorrhage, which is bleeding between the dura mater and the skull, resulting in a significant period of unconsciousness lasting between 6 and 24 hours. This condition is typically caused by head trauma and is a medical emergency due to potential for rapid neurological deterioration from increased intracranial pressure.

Apply this code for patients presenting with an acute epidural hematoma confirmed by imaging (e.g., CT scan) following head injury, where the documented loss of consciousness was explicitly within the 6 to 24-hour timeframe. Documentation must clearly state the duration of unconsciousness and that this is the initial treatment encounter for the injury.

• Ensure the duration of loss of consciousness is precisely documented as 6 to 24 hours; do not use for durations outside this range.
• Verify that the encounter is indeed the "initial encounter" for this specific injury; subsequent care would require a different seventh character.
• Differentiate carefully from subdural or subarachnoid hemorrhages, as these have distinct ICD-10-CM codes.
