ICD-11 code 3A20.4 categorizes alloimmune haemolytic anaemia, a condition in which red blood cells are destroyed by the body’s immune system due to the presence of antibodies from another individual. This type of anaemia occurs when the body recognizes foreign antigens on red blood cells as a threat, leading to their destruction and subsequent decrease in oxygen-carrying capacity.
Alloimmune haemolytic anaemia can result from blood transfusions, transplantation of organs or tissues, or during pregnancy when the mother’s antibodies attack the baby’s red blood cells. This condition can lead to symptoms such as fatigue, pale skin, jaundice, and increased heart rate. Prompt diagnosis and treatment are essential to prevent complications such as organ damage or shock.
Treatment for alloimmune haemolytic anaemia may include medications to suppress the immune system, blood transfusions to replace destroyed red blood cells, or plasmapheresis to remove harmful antibodies from the bloodstream. In severe cases, splenectomy (removal of the spleen) may be necessary to prevent ongoing destruction of red blood cells. It is important for individuals with this condition to follow up with healthcare providers regularly to monitor their blood counts and receive appropriate care.

#️⃣ Coding Considerations
In the world of healthcare coding, the SNOMED CT code equivalent to ICD-11 code 3A20.4 (Alloimmune haemolytic anaemia) is 36023002. This code specifically refers to the condition of alloimmune hemolytic anemia, which occurs when the body’s immune system attacks its own red blood cells due to exposure to different blood types. The SNOMED CT code serves as a standardized way to classify and document this particular type of hemolytic anemia, allowing for easier communication and data analysis across healthcare systems.
Healthcare professionals rely on accurate coding to ensure proper diagnosis and treatment for patients with alloimmune hemolytic anemia. By using the SNOMED CT code 36023002, clinicians can quickly and efficiently identify and address this specific form of hemolytic anemia in their patients. This standardized coding system helps streamline the healthcare process and improve patient outcomes in cases of alloimmune hemolytic 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 3A20.4, also known as Alloimmune Haemolytic Anaemia, may vary depending on the severity of the condition. Patients may experience fatigue, weakness, and pale skin due to the decreased number of red blood cells in the body. Additionally, individuals with this form of anaemia may exhibit symptoms such as shortness of breath, rapid heartbeat, and yellowing of the skin and eyes, known as jaundice.
In more severe cases of Alloimmune Haemolytic Anaemia, patients may also present with dark urine, which is a result of the breakdown of red blood cells in the body. This condition may cause abdominal pain, particularly in the area of the liver and spleen. Some individuals may also develop complications such as gallstones due to the increased levels of bilirubin in the blood.
Other symptoms of 3A20.4 may include enlargement of the liver and spleen, as well as an increased risk of infections. Patients may also experience symptoms related to the underlying cause of the condition, such as fever, chills, and signs of autoimmune disorders. It is important for individuals experiencing these symptoms to seek medical attention for proper diagnosis and treatment.
🩺 Diagnosis
Diagnosis of 3A20.4, also known as Alloimmune Haemolytic Anaemia, involves a variety of methods to accurately identify the condition. One common diagnostic tool is a complete blood count (CBC), which can reveal low levels of red blood cells and hemoglobin characteristic of haemolytic anaemia. In addition, reticulocyte count may be performed to assess the rate of red blood cell production in response to the destruction of red blood cells.
Another crucial aspect of the diagnostic process involves blood smears, which can provide visual confirmation of red blood cell abnormalities such as spherocytes or schistocytes, indicating haemolysis. Coombs test, also known as direct antiglobulin test, is commonly used to detect the presence of antibodies or complement proteins on the surface of red blood cells, a hallmark of Alloimmune Haemolytic Anaemia. Furthermore, antibody screening may be conducted to identify specific antibodies attacking red blood cells in the immune-mediated destruction process.
Bone marrow biopsy may be considered in certain cases to evaluate if the bone marrow is responding appropriately to the increased demand for red blood cell production in response to haemolysis. Genetic testing may also be recommended to identify inherited conditions that predispose individuals to Alloimmune Haemolytic Anaemia. Overall, a combination of these diagnostic methods is essential to accurately diagnose and manage 3A20.4 effectively.
💊 Treatment & Recovery
Treatment for 3A20.4, also known as Alloimmune haemolytic anaemia, typically involves addressing the underlying cause of the condition. This may include controlling the immune response that is attacking the red blood cells through medication such as corticosteroids or immunosuppressants.
In severe cases of Alloimmune haemolytic anaemia, patients may require blood transfusions to replace the damaged red blood cells. These transfusions can help alleviate symptoms such as fatigue and weakness caused by the decreased oxygen-carrying capacity of the blood.
Recovery from Alloimmune haemolytic anaemia can vary depending on the severity of the condition and how well it responds to treatment. In some cases, patients may experience a complete recovery with appropriate medical interventions, while others may require ongoing monitoring and management to prevent relapses. It is important for individuals with this condition to work closely with their healthcare providers to develop a personalized treatment plan.
🌎 Prevalence & Risk
In the United States, alloimmune haemolytic anaemia, coded as 3A20.4, is considered a relatively rare condition. Estimates indicate that the prevalence of this condition may be less than one in 100,000 individuals. The exact prevalence may vary depending on factors such as geographic location, demographics, and access to healthcare services.
In Europe, the prevalence of alloimmune haemolytic anaemia is similarly low. Studies suggest that the incidence of this condition may be slightly higher than in the United States, but exact numbers vary between countries. Limited data is available on the prevalence of 3A20.4 in Europe due to the rare nature of the condition and the challenges associated with accurate diagnosis and reporting.
In Asia, alloimmune haemolytic anaemia is also considered a rare disorder. Limited research has been conducted on the prevalence of this condition in Asian populations, making it difficult to ascertain exact numbers. However, anecdotal evidence and case reports suggest that the incidence of 3A20.4 may be comparable to that seen in the United States and Europe.
In Africa, the prevalence of alloimmune haemolytic anaemia is poorly documented. Limited research and data collection efforts in many African countries contribute to the lack of information on the prevalence of 3A20.4 in this region. Further studies are needed to better understand the epidemiology of alloimmune haemolytic anaemia in Africa and other regions around the world.
😷 Prevention
To prevent alloimmune haemolytic anaemia, it is essential to avoid blood transfusions from incompatible donors. This can be achieved through thorough screening of donors and recipients to ensure proper matching of blood types. Additionally, the use of leukocyte-depleted blood products can help reduce the risk of alloimmune reactions.
Patients with autoimmune haemolytic anaemia should be closely monitored by healthcare professionals to detect and treat any potential complications early on. Regular blood tests can help track the patient’s hemoglobin levels and identify any signs of hemolysis. Prompt treatment of any underlying infections or autoimmune diseases can also help prevent exacerbation of the condition.
In cases where alloimmune haemolytic anaemia is caused by pregnancy, close monitoring of the mother and fetus is crucial. Regular prenatal check-ups can help identify any signs of fetal hemolytic disease early on. In severe cases, intrauterine transfusions may be necessary to prevent complications in the fetus. Close collaboration between obstetricians and hematologists is essential to ensure optimal care for both the mother and baby.
🦠 Similar Diseases
A related disease to 3A20.4 is Autoimmune Hemolytic Anemia (AIHA), with a code of D59. This condition is characterized by the immune system attacking the body’s red blood cells, leading to their destruction and causing anemia. AIHA can be classified as warm or cold depending on the antibodies involved in the destruction of red blood cells.
Another comparable disease is Drug-induced Immune Hemolytic Anemia (DIIHA), with a code of D59.1. This condition occurs when certain medications trigger the immune system to attack red blood cells, leading to hemolysis. DIIHA can be caused by a wide range of drugs, including antibiotics, anti-inflammatory drugs, and antiretrovirals.
Paroxysmal Nocturnal Hemoglobinuria (PNH) is a relevant disease with a code of D59.5. This condition is characterized by the destruction of red blood cells due to a deficiency in certain proteins on the cell surface, making the cells more susceptible to immune attack. PNH can lead to symptoms such as hemolysis, blood clots, and bone marrow failure. Treatment options for PNH may include blood transfusions and medications to suppress immune system activity.
