Non-ABO incompat w acute hemolytic transfs react, init

This code signifies an acute hemolytic transfusion reaction occurring due to an incompatibility other than the ABO blood group system. This severe immune response results in the rapid destruction of red blood cells in the recipient, typically manifesting within 24 hours of the transfusion.

Use this code when a patient experiences an immediate and severe adverse reaction to a blood transfusion, confirmed to be hemolytic and not related to ABO incompatibility. This often involves antibodies to minor blood group antigens. It is appropriate for the initial treatment of such a reaction.

• Ensure documentation clearly states "acute hemolytic transfusion reaction" and specifies "non-ABO incompatibility."
• Verify that this is the first encounter for the management of this specific reaction.
• Code any associated signs and symptoms or complications separately, if applicable.
