Non-ABO incompat w acute hemolytic transfs react, sequela

This code signifies long-term complications or conditions arising from an acute hemolytic transfusion reaction that was caused by an incompatibility other than the ABO blood group system. These sequelae are persistent health issues directly attributable to the initial adverse transfusion event.

Apply this code when documenting chronic or residual effects in a patient who previously experienced an acute hemolytic transfusion reaction due to non-ABO incompatibility. This is used for follow-up encounters where the patient is being treated for the lasting consequences of that reaction, not the acute event itself.

• Always assign an additional code to specify the exact nature of the sequela (e.g., chronic renal failure, persistent anemia).
• Ensure documentation clearly links the current condition to the past non-ABO acute hemolytic transfusion reaction.
• This code is for sequelae, not for the initial acute reaction or subsequent acute reactions.
