Rh incompat w delayed hemolytic transfs react, sequela

This code signifies a long-term or residual effect stemming from a delayed hemolytic transfusion reaction caused by Rh incompatibility. This means the patient previously received a blood transfusion where their immune system reacted to Rh antigens in the donor blood, leading to a delayed breakdown of red blood cells, and is now experiencing lasting consequences of that reaction.

Use this code when documenting a patient's current medical condition that is a direct result of a past, delayed hemolytic transfusion reaction due to Rh incompatibility. This applies to follow-up encounters where the sequelae, rather than the acute reaction, are being treated or monitored.

• Always assign an additional code(s) to specify the exact nature of the sequela (e.g., chronic anemia, renal failure).
• Ensure documentation clearly links the current condition to the previous Rh incompatibility-related delayed hemolytic transfusion reaction.
• This "S" code indicates sequela and should be used for complications or conditions that arise as a direct result of the initial injury or disease, after the acute phase has terminated.
