Traumatic cerebral edema w/o loss of consciousness, init

This code signifies swelling of the brain tissue resulting from a head injury, where the patient did not experience a loss of consciousness. This edema is a direct consequence of trauma and can lead to increased intracranial pressure.

Apply this code for patients presenting with acute cerebral edema directly attributable to a recent head injury, confirmed by imaging (e.g., CT scan) or clinical assessment, and who remained conscious throughout the event. Documentation should clearly state the traumatic etiology and absence of syncope or unresponsiveness.

• Ensure documentation explicitly states "without loss of consciousness" to differentiate from codes indicating altered consciousness.
• Verify the encounter is the "initial encounter" for the injury; subsequent care would use a different seventh character.
• Always code the underlying cause of the trauma (e.g., fall, motor vehicle accident) as an external cause code.
