ICD-11 code 3A20.Y refers to “Other specified acquired haemolytic anaemia, immune.” This code is used in the International Classification of Diseases (ICD) to classify and code cases of acquired hemolytic anemia that are immune-mediated and do not fit into other specific categories or coding options.
Hemolytic anemia is a condition where red blood cells are broken down faster than they can be produced, leading to a shortage of healthy red blood cells in the body. This particular code is assigned to cases where the immune system attacks and destroys red blood cells, causing hemolysis.
By categorizing and coding cases of acquired hemolytic anemia with this code, healthcare professionals can accurately document and track the prevalence and incidence of immune-mediated hemolysis, allowing for better understanding and management of these specific types of anemia.

In the United States, ICD-11 is not yet in use. The U.S. is currently using ICD-10-CM (Clinical Modification), which has been adapted from the WHO’s ICD-10 to better suit the American healthcare system’s requirements for billing and clinical purposes. The Centers for Medicare and Medicaid Services (CMS) have not yet set a specific date for the transition to ICD-11.
The situation in Europe varies by country. Some European nations are considering the adoption of ICD-11 or are in various stages of planning and pilot studies. However, as with the U.S., full implementation may take several years due to similar requirements for system updates and training.
🔎 Symptoms
Symptoms of 3A20.Y (Other specified acquired haemolytic anaemia, immune) typically include fatigue, weakness, and pale skin due to decreased red blood cells in the body. Patients may also experience shortness of breath, lightheadedness, and rapid heartbeat as a result of reduced oxygen delivery to tissues and organs. Additionally, jaundice, a yellowing of the skin and eyes, may occur due to the breakdown of red blood cells and the release of bilirubin.
Further symptoms of this condition may manifest as dark urine, abdominal pain, and an enlarged spleen as the body tries to compensate for the loss of red blood cells. Some patients may also develop a fever, chills, and infections more easily due to a weakened immune system resulting from the underlying autoimmune reaction. Additionally, individuals with this type of acquired haemolytic anaemia may experience headaches, dizziness, and cold hands and feet as a result of impaired circulation worsened by the anaemia.
In severe cases of 3A20.Y, patients may exhibit chest pain, confusion, and difficulty concentrating due to inadequate oxygen supply to the brain and heart. Some individuals may also present with leg cramps, joint pain, and an increased heart rate as the body attempts to compensate for the oxygen deficiency. Furthermore, bruising, petechiae, and abnormal bleeding may occur due to decreased platelet levels resulting from the immune-mediated destruction of blood cells.
🩺 Diagnosis
Diagnosis of 3A20.Y (Other specified acquired haemolytic anaemia, immune) requires a thorough assessment of the patient’s medical history, including any previous or current illnesses, medication use, autoimmune conditions, and family history of hematologic disorders. Physical examination can also provide important clues, such as signs of jaundice, enlarged spleen, or petechiae.
Laboratory tests play a crucial role in the diagnosis of immune hemolytic anemias. Complete blood count (CBC) will typically show low hemoglobin levels, elevated reticulocyte count, and signs of hemolysis such as low haptoglobin levels and elevated LDH levels. Peripheral blood smear may reveal abnormal red blood cell morphology, such as spherocytes or schistocytes, indicating hemolysis.
Direct antiglobulin test (DAT) is a key diagnostic test for immune hemolytic anemia, where antibodies and complement proteins are detected on the surface of red blood cells. Autoantibodies or alloantibodies may be present, helping to identify the underlying cause of hemolysis. Additional tests, such as cold agglutinin titers, warm autoantibody titers, and specific antibody identification tests, may be performed to further characterize the immune mechanism involved in hemolysis. Bone marrow biopsy may be considered in some cases to evaluate erythropoiesis and exclude other causes of anemia.
💊 Treatment & Recovery
Treatment and recovery methods for 3A20.Y, which is classified as Other specified acquired haemolytic anaemia, immune, typically involve addressing the underlying cause of the condition. In cases where the anaemia is caused by an autoimmune disorder, treatment may include immunosuppressive therapy to suppress the immune response that is attacking the red blood cells. This can help to prevent further destruction of red blood cells and improve the individual’s overall health.
In some cases, individuals with 3A20.Y may require blood transfusions to help maintain a safe level of red blood cells in the body. Transfusions can provide immediate relief from symptoms of anaemia such as fatigue, weakness, and shortness of breath. Regular monitoring of blood counts and iron levels may be necessary to determine the frequency and necessity of blood transfusions for each individual.
In severe cases of 3A20.Y, where other treatment methods have not been effective, a splenectomy may be considered. This surgical procedure involves removing the spleen, which is responsible for filtering the blood and removing old or damaged red blood cells. By eliminating the source of red blood cell destruction, a splenectomy can help improve symptoms of anaemia and promote recovery. However, this procedure is typically reserved for individuals who do not respond to other treatment options.
🌎 Prevalence & Risk
In the United States, the prevalence of 3A20.Y (Other specified acquired haemolytic anaemia, immune) is estimated to be around 1-3 cases per 100,000 population. This rare condition primarily affects adults and is more commonly seen in individuals of African or Mediterranean descent. While the exact prevalence data may vary due to underdiagnosis and underreporting, it is generally considered to be a relatively uncommon disorder in the US.
In Europe, the prevalence of 3A20.Y is slightly higher than in the United States, with an estimated 3-5 cases per 100,000 population. Countries in Southern Europe, such as Italy and Greece, have been reported to have a higher incidence of immune-mediated haemolytic anaemias compared to Northern European countries. The prevalence of this condition in Europe may also be influenced by genetic factors and environmental triggers.
In Asia, the prevalence of 3A20.Y is less well-studied compared to Western countries. However, immune-mediated haemolytic anaemias are known to occur in Asian populations, with varying frequencies among different ethnic groups. Limited data suggest that the prevalence of this condition in Asia may be similar to that in the United States, but further research is needed to accurately assess the burden of immune-mediated haemolytic anaemias in the region.
In Africa, the prevalence of 3A20.Y is not well-documented, but immune-mediated haemolytic anaemias are known to occur in African populations. Factors such as infectious diseases, nutritional deficiencies, and genetic predisposition may contribute to the prevalence of this condition in Africa. More studies are needed to understand the epidemiology of immune-mediated haemolytic anaemias in African countries and develop appropriate management and treatment strategies.
😷 Prevention
To prevent 3A20.Y (Other specified acquired haemolytic anaemia, immune), it is crucial to identify and address the underlying causes of the condition. This may involve addressing any underlying infections or immune disorders that may be contributing to the development of immune-mediated haemolytic anaemia. Additionally, certain medications can trigger an immune response leading to haemolysis, so it is important to monitor and, if possible, avoid these medications in susceptible individuals.
One important preventative measure is to maintain a healthy lifestyle and balanced diet. Consuming a diet rich in nutrients, such as iron and vitamin B12, can help support the production of red blood cells and prevent anaemia. Staying hydrated and getting regular exercise can also support overall immune function and reduce the likelihood of developing haemolytic anaemia.
Regular medical check-ups are essential for early detection and management of any underlying conditions that may predispose individuals to immune-mediated haemolytic anaemia. By staying proactive with preventive healthcare, individuals can work with their healthcare provider to address any potential risk factors and take necessary steps to mitigate the development of this condition. Early intervention and management of underlying conditions are key in preventing immune-mediated haemolytic anaemia.
🦠 Similar Diseases
Diseases similar to 3A20.Y include autoimmune hemolytic anemia (AIHA), which is characterized by the destruction of red blood cells by the body’s immune system. This condition can be secondary to underlying conditions such as systemic lupus erythematosus, lymphoma, or certain medications. The main symptoms of AIHA include fatigue, pale skin, jaundice, and dark urine.
Another disease similar to 3A20.Y is paroxysmal nocturnal hemoglobinuria (PNH), a rare disorder in which red blood cells are prematurely destroyed by the complement system. PNH is caused by mutations in the PIGA gene, leading to a deficiency of protective proteins on red blood cells. Patients with PNH may experience symptoms such as hemoglobinuria, abdominal pain, thrombosis, and fatigue.
Cold agglutinin disease (CAD) is also related to 3A20.Y, characterized by the presence of cold-reacting autoantibodies that target red blood cells. These antibodies can lead to the destruction of red blood cells when exposed to cold temperatures. Patients with CAD may exhibit symptoms such as Raynaud’s phenomenon, acrocyanosis, and hemolytic anemia triggered by cold exposure. Treatment options for CAD include avoiding cold temperatures and immunosuppressive therapy.
