Contus/lac cereb, w LOC of 30 minutes or less, subs

This code signifies a cerebral contusion or laceration, without further specification of the injury type, that resulted in a brief period of unconsciousness (30 minutes or less). It indicates that the patient is receiving follow-up care for this brain injury, not the initial treatment.

Apply this code when a patient presents for ongoing management, rehabilitation, or follow-up appointments related to a previously diagnosed cerebral contusion or laceration. Documentation should clearly state "subsequent encounter" or similar language indicating care after the initial treatment phase, and confirm the duration of unconsciousness was 30 minutes or less.

• Ensure documentation specifies "subsequent encounter" to differentiate from initial care.
• Verify the duration of loss of consciousness; codes vary for different timeframes.
• Do not use if the specific type of cerebral contusion (e.g., focal, diffuse) is documented; use a more specific code.
