Contus/lac/hem brainstem w LOC of 31-59 min, init

This code signifies a traumatic injury to the brainstem, characterized by bruising, tearing, and bleeding within the tissue, resulting in a moderate period of unconsciousness lasting between 31 and 59 minutes. It indicates the initial presentation and treatment of such an injury.

Apply this code for patients presenting with a brainstem injury due to trauma, where clinical documentation clearly states a contusion, laceration, and hemorrhage, and explicitly records a loss of consciousness duration within the 31-59 minute range. This code is appropriate for the initial hospital visit or emergency department encounter for this specific injury.

• Ensure the documentation specifies brainstem involvement, not just a general brain injury.
• Verify the exact duration of loss of consciousness; codes vary significantly based on this parameter.
• This "A" suffix indicates an initial encounter; use subsequent encounter codes for follow-up care.
