Non-ABO incompat react d/t tranfs of bld/bld prod,unsp, init

This code signifies an adverse reaction to a blood transfusion or blood product that is not related to the ABO blood group system. It indicates that the specific type of non-ABO incompatibility is currently unknown or not documented. This reaction occurred during the initial treatment or encounter for the event.

Use this code when a patient experiences an acute transfusion reaction, such as fever, chills, or hypotension, following the administration of blood or blood products, and initial investigations rule out ABO incompatibility. It is appropriate when the specific non-ABO antibody causing the reaction has not yet been identified or confirmed.

• Always strive for a more specific code if the type of non-ABO incompatibility is identified (e.g., anti-Kell, anti-Duffy).
• Ensure documentation clearly states "initial encounter" for the transfusion reaction.
• Code any associated signs and symptoms of the reaction in addition to this code.
