Rh incompatibility w acute hemolytic transfs react, init

This diagnosis indicates an immediate and severe immune response occurring after a blood transfusion, specifically due to a mismatch in Rh factors between the transfused blood and the recipient's own blood. The recipient's antibodies attack the transfused red blood cells, leading to their destruction (hemolysis).

This code is appropriate for documenting the initial presentation and management of a patient experiencing an acute hemolytic transfusion reaction caused by Rh incompatibility. This typically occurs shortly after or during a blood transfusion. It is used when the patient is first evaluated and treated for this specific adverse event.

• Ensure documentation clearly specifies Rh incompatibility as the cause of the hemolytic reaction.
• Verify the encounter is indeed the "initial encounter" for this specific transfusion reaction.
• Do not use for delayed hemolytic reactions or reactions due to other blood group incompatibilities.
