T80.30 ABO incompatibility reaction due to transfusion of blood or blood products, unspecified

Name of the Condition

• ABO incompatibility reaction due to transfusion of blood or blood products, unspecified

Summary

This condition describes an adverse reaction resulting from the transfusion of blood or blood products that are incompatible with the recipient's ABO blood group. It is a serious complication that can lead to hemolysis, organ dysfunction, and other systemic effects. The reaction occurs when antibodies in the recipient's blood attack antigens on the transfused blood cells, triggering an immune response.

Causes

ABO incompatibility reactions are caused by the transfusion of blood or blood products that do not match the recipient's ABO blood type. This mismatch leads to the destruction of transfused red blood cells by the recipient's antibodies, resulting in hemolysis. Errors in blood typing, crossmatching, or administration can contribute to this complication.

Risk Factors

• Incorrect blood typing or crossmatching
• Human error during transfusion preparation or administration
• Use of pooled blood products with undetected incompatibilities
• Emergency transfusions without full compatibility testing
• Lack of proper verification protocols

Symptoms

• Fever, chills, or rigors
• Flank pain or back pain
• Hemoglobinuria (dark urine)
• Hypotension or tachycardia
• Dyspnea or respiratory distress
• Jaundice or pallor
• Nausea, vomiting, or headache

Diagnosis

Diagnosis is based on clinical presentation, transfusion history, and laboratory tests. Key findings include evidence of hemolysis (e.g., elevated bilirubin, decreased haptoglobin), positive direct antiglobulin test, and confirmation of ABO incompatibility. Urinalysis may show hemoglobinuria, and blood cultures can rule out infection.

Treatment Options

Treatment focuses on stopping the transfusion immediately, maintaining hemodynamic stability, and managing hemolysis. Supportive care includes fluid resuscitation, monitoring for renal impairment, and addressing electrolyte imbalances. In severe cases, dialysis or other interventions may be necessary.

Prognosis and Follow-Up

Prognosis depends on the severity of the reaction and promptness of treatment. Mild cases may resolve with supportive care, while severe reactions can lead to acute kidney injury or multiorgan failure. Follow-up includes monitoring renal function, hemoglobin levels, and ensuring no further transfusion errors occur.

Complications

• Acute kidney injury or renal failure
• Disseminated intravascular coagulation (DIC)
• Shock or cardiovascular collapse
• Neurological impairment
• Death (in severe cases)

Lifestyle & Prevention

Prevention relies on strict adherence to blood typing, crossmatching, and verification protocols. Double-checking patient and donor blood compatibility before transfusion is critical. Training staff on proper procedures and using barcoding systems can reduce errors.

When to Seek Professional Help

Seek immediate medical attention if symptoms of transfusion reaction occur, such as fever, chills, pain, or respiratory distress. Prompt evaluation is essential to minimize complications and initiate appropriate treatment.

Tips for Medical Coders

Document the transfusion event, including the blood product type and any immediate reactions. Specify if the incompatibility was due to error or other factors. Ensure the code T80.30 is used when the reaction is unspecified and not further detailed. Include details about the transfusion context and clinical findings to support coding accuracy.
