Mixed type autoimmune hemolytic anemia
ICD-10 D59.13 is a billable code used to indicate a diagnosis of mixed type autoimmune hemolytic anemia.
Mixed type autoimmune hemolytic anemia (AIHA) is a hematological disorder characterized by the destruction of red blood cells (RBCs) due to the immune system mistakenly targeting them. This condition can be classified into two main types: warm AIHA, where antibodies react at body temperature, and cold AIHA, where antibodies react at lower temperatures. Patients may present with symptoms such as fatigue, pallor, jaundice, and splenomegaly. The mixed type indicates the presence of both warm and cold antibodies, complicating the clinical picture and management. Diagnosis typically involves laboratory tests including a complete blood count (CBC), reticulocyte count, direct Coombs test, and peripheral blood smear. Treatment may include corticosteroids, immunosuppressive agents, or splenectomy, depending on the severity and underlying causes. Genetic factors, such as certain enzyme deficiencies and hereditary conditions like thalassemia and sickle cell disease, can also contribute to the risk of developing hemolytic anemia, necessitating a comprehensive evaluation of the patient's history and genetic background.
Detailed lab results, patient history, and treatment plans must be documented.
Diagnosis and management of AIHA, evaluation of hemolytic anemia in patients with autoimmune disorders.
Ensure clarity in distinguishing between warm and cold AIHA for accurate coding.
Documentation of autoimmune conditions and their relationship to hemolytic anemia.
Management of patients with autoimmune diseases presenting with hemolytic anemia.
Document any concurrent autoimmune disorders that may contribute to the condition.
Used to evaluate anemia in patients suspected of having AIHA.
Document the reason for the CBC and reticulocyte count, including symptoms and clinical findings.
Hematologists should ensure comprehensive lab results are included.
Common symptoms include fatigue, pallor, jaundice, and splenomegaly, which result from the destruction of red blood cells.
Diagnosis is made through clinical evaluation, laboratory tests including CBC, reticulocyte count, and direct Coombs test.
