Traum subdr hem w/o loss of consciousness, init

This code signifies a collection of blood between the dura mater and arachnoid mater of the brain, resulting from trauma, where the patient did not experience any loss of consciousness at the time of injury. It indicates an acute subdural hemorrhage that is not associated with an altered mental state.

Use this code for patients presenting with a traumatic subdural hemorrhage confirmed by imaging (e.g., CT scan, MRI) who were fully conscious immediately following the injury. Documentation should clearly state the traumatic etiology and the absence of loss of consciousness. This code is appropriate for the initial treatment phase of the injury.

• Ensure documentation explicitly states "without loss of consciousness" to differentiate from codes indicating altered consciousness.
• Always sequence this code first if it is the primary reason for the encounter.
• Verify the encounter type (initial, subsequent, sequela) to select the correct 7th character.
