Acute hemolytic transfs react, unsp incompatibility, sequela

This code signifies a long-term complication or residual effect stemming from an acute hemolytic transfusion reaction. This reaction occurs when incompatible blood components are transfused, leading to rapid destruction of red blood cells. The specific incompatibility type causing the original acute event is not documented or is unknown.

Use this code when documenting a patient presenting with chronic issues directly attributable to a past acute hemolytic transfusion reaction. This applies when the original acute event has resolved, but the patient continues to experience sequelae such as chronic kidney disease, iron overload, or other persistent organ damage. It is appropriate when the specific blood incompatibility that caused the initial reaction was not identified or is not specified in the medical record.

• Always sequence this code after the code(s) identifying the specific sequela (e.g., chronic kidney disease).
• Ensure documentation clearly links the current condition to a past acute hemolytic transfusion reaction.
• Avoid using this code for the initial acute event; instead, use the appropriate acute reaction code.
