Non-ABO incompat w delayed hemolytic transfs react, sequela

This code signifies a long-term complication or residual effect stemming from a delayed hemolytic transfusion reaction caused by non-ABO blood group incompatibility. This type of reaction occurs more than 24 hours after a transfusion, often due to antibodies to minor blood group antigens, leading to gradual destruction of transfused red blood cells. The "sequela" aspect indicates that the patient is now experiencing a chronic or lasting health problem directly attributable to this past transfusion event.

Use this code when documenting a patient's current condition that is a direct consequence of a previously experienced delayed hemolytic transfusion reaction due to non-ABO incompatibility. This applies to follow-up encounters where the long-term effects, such as chronic anemia, renal insufficiency, or other organ damage, are being managed. It should be assigned after the acute phase of the reaction has resolved, and the patient is dealing with the lasting impact.

• Always assign an additional code(s) to specify the exact nature of the sequela (e.g., specific type of anemia, chronic kidney disease).
• Ensure documentation clearly links the current condition to the past delayed hemolytic transfusion reaction.
• This code is for the sequela of the reaction, not the acute reaction itself.
