Contus/lac/hem brainstem w/o loss of consciousness, subs

This code signifies a brainstem injury involving bruising, tearing, or bleeding, where the patient did not lose consciousness. It specifically applies to follow-up care for this type of trauma.

Apply this code for subsequent encounters when a patient is receiving ongoing treatment or monitoring for a previously diagnosed brainstem contusion, laceration, or hemorrhage without a history of unconsciousness. Documentation should clearly indicate the "subsequent encounter" status, such as follow-up visits, rehabilitation sessions, or medication adjustments.

• Ensure documentation explicitly states "without loss of consciousness" for the initial injury.
• Distinguish carefully between initial and subsequent encounters; the 7th character 'D' is crucial here.
• Always code the underlying cause of the injury (e.g., fall, motor vehicle accident) as an external cause code.
