Non-ABO incompat w delayed hemolytic transfs react, init

This code signifies a delayed adverse reaction to a blood transfusion caused by incompatibility between the recipient's and donor's blood, specifically involving non-ABO blood group antigens. This reaction typically manifests days to weeks after the transfusion, leading to the destruction of red blood cells.

Use this code when a patient presents with signs and symptoms of a delayed hemolytic transfusion reaction, such as unexplained anemia, jaundice, or fever, occurring after a blood transfusion. This diagnosis is often confirmed by laboratory findings indicating red blood cell destruction and the presence of antibodies against non-ABO antigens.

• Ensure documentation clearly specifies a "delayed" reaction and identifies the incompatibility as "non-ABO."
• This code is for the "initial encounter" for this specific transfusion reaction. Subsequent care for the same reaction would require a different encounter character.
• Always review the patient's transfusion history and laboratory results to confirm the diagnosis and type of incompatibility.
