T80.A
Non-ABO incompatibility reaction due to transfusion of blood or blood products
Clinical Classification Guidelines
Inclusion Terms
- Reaction due to incompatibility of minor antigens (Duffy) (Kell) (Kidd) (Lewis) (M) (N) (P) (S)
Medical Intelligence & Overview
A Non-ABO incompatibility reaction occurs when the immune system reacts adversely to blood or blood products transfused from a donor, due to incompatibility of minor blood group antigens. Unlike ABO incompatibility, which involves the primary blood group system, this reaction involves other blood group antigens such as Duffy, Kell, Kidd, Lewis, M, N, P, and S. These reactions can cause a range of symptoms and complications after a transfusion and are an important consideration in transfusion medicine.
Causes & Symptoms
Clinical Causes: Mismatch of minor blood group antigens between the donor and recipient, particularly Duffy, Kell, Kidd, Lewis, M, N, P, or S antigens Lack of proper blood typing and cross-matching for these minor antigens prior to transfusion Previous sensitization to minor blood group antigens through past transfusions, pregnancies, or transplants Use of blood products without thorough antigen matching for minor blood group systems
Key Symptoms: Fever and chills Fewer or no immediate symptoms compared to ABO incompatibility but may develop over hours to days Mild skin reactions such as rash or hives In some cases, symptoms of hemolytic transfusion reaction like dark urine, jaundice, or back pain Low-grade fever may be the only initial sign in mild cases
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a detailed medical history, including previous transfusions or pregnancies, and laboratory tests such as antibody screening and identification of specific donor-recipient incompatibilities. Blood typing for minor antigens should be performed to confirm incompatibility. Hemolysis markers, including hemoglobin levels, bilirubin, and lactate dehydrogenase, may also be assessed to evaluate the severity of the reaction.
Treatment Protocols: Treatment of a Non-ABO incompatibility reaction is primarily supportive. Mild reactions may resolve without specific intervention, but more severe symptoms require prompt medical management, which can include:
Clinical Advice & FAQs
Billing Guidance
Is T80.A a billable ICD-10 code?
Yes, T80.A is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report T80.A?
Clinical documentation must specify the nature of Non-ABO incompatibility reaction due to transfusion of blood or blood products and any associated comorbidities for accurate reporting.
