Contus/lac/hem brainstem w LOC of 1-5 hrs 59 min, subs

This code signifies a brainstem injury characterized by bruising, tearing, and bleeding, accompanied by a loss of consciousness lasting between one hour and five hours and fifty-nine minutes. It specifically denotes a subsequent encounter for this injury, indicating ongoing care after the initial treatment.

Apply this code for follow-up visits, rehabilitation, or ongoing management of a patient previously diagnosed with a brainstem contusion, laceration, and hemorrhage who experienced a moderate period of unconsciousness. Documentation should clearly state the nature of the brainstem injury, the duration of the initial loss of consciousness, and that this is not the initial encounter for the injury.

• Ensure the medical record explicitly states "subsequent encounter" or indicates ongoing treatment for the injury.
• Verify the duration of loss of consciousness falls precisely within the 1 hour to 5 hours 59 minutes range.
• Differentiate from initial encounters (A) or sequela (S) codes for similar brain injuries.
