Contus/lac cereb, w loss of consciousness of 31-59 min, subs

This code signifies a traumatic brain injury involving bruising and/or tearing of the cerebrum, where the patient experienced a loss of consciousness lasting between 31 and 59 minutes. It indicates that the patient is receiving follow-up care for this specific injury after the initial treatment.

Apply this code for patients presenting for ongoing management, rehabilitation, or follow-up appointments related to a previously diagnosed cerebral contusion or laceration. Documentation should clearly state the nature of the cerebral injury, the duration of the initial loss of consciousness, and that this is not the initial encounter for treatment.

• Ensure the documentation explicitly states "subsequent encounter" or indicates follow-up care for the injury.
• Verify the exact duration of loss of consciousness; codes vary significantly based on this timeframe.
• Differentiate from initial encounter codes (ending in A) and sequela codes (ending in S) for chronic effects.
