ICD-11 code 3A20 refers to acquired hemolytic anemia, immune. This condition occurs when the body’s immune system mistakenly attacks and destroys its own red blood cells, leading to a shortage of healthy red blood cells in the body. The destruction of red blood cells can cause symptoms such as fatigue, weakness, and jaundice.
Acquired hemolytic anemia can be caused by a variety of factors, including autoimmune disorders like lupus or rheumatoid arthritis, infections such as hepatitis or malaria, or certain medications like antibiotics or antimalarial drugs. In some cases, the underlying cause of the immune response is unknown. Treatment for acquired hemolytic anemia typically involves addressing the underlying cause, managing symptoms, and in some cases, receiving blood transfusions or medications to suppress the immune system. Early diagnosis and proper management of acquired hemolytic anemia are crucial to prevent complications and improve overall health outcomes.

#️⃣ Coding Considerations
The equivalent SNOMED CT code for the ICD-11 code 3A20 (Acquired haemolytic anaemia, immune) is 79754008. This SNOMED CT code specifically refers to the condition of auto-immune hemolytic anemia, which is characterized by the destruction of red blood cells by the body’s own immune system. This condition can lead to symptoms such as fatigue, pale skin, and shortness of breath due to decreased oxygen-carrying capacity in the blood. By accurately capturing this information in electronic health records, healthcare providers can more effectively diagnose and treat patients with this type of blood disorder. With the use of standardized codes like SNOMED CT, medical professionals can quickly and accurately communicate vital information about a patient’s condition, improving the overall quality of care provided.
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, acquired haemolytic anaemia, immune, can vary depending on the severity of the condition. In general, patients may present with symptoms such as fatigue, weakness, and pale skin due to the decreased number of red blood cells in the body. Additionally, individuals may experience shortness of breath, rapid heartbeat, and dizziness as a result of the anaemia affecting the body’s ability to transport oxygen effectively.
Patients with immune acquired haemolytic anaemia may also exhibit symptoms such as jaundice, which is characterized by yellowing of the skin and eyes due to the breakdown of red blood cells releasing bilirubin into the bloodstream. Other common symptoms include dark urine, abdominal pain, and an enlarged spleen as the immune system targets and destroys red blood cells that are still in circulation. It is important for individuals experiencing these symptoms to seek medical attention for proper diagnosis and treatment.
In more severe cases of 3A20, acquired haemolytic anaemia, immune, patients may develop complications such as anemia-related heart problems, increased risk of infections, and organ damage due to the lack of oxygen reaching the tissues and organs. These complications can lead to serious health issues if left untreated. Therefore, it is crucial for individuals with suspected immune acquired haemolytic anaemia to undergo thorough medical evaluation and follow their healthcare provider’s recommendations for management and treatment.
🩺 Diagnosis
Diagnosis of Acquired Haemolytic Anaemia, Immune (3A20) involves a combination of clinical evaluation, laboratory tests, and imaging studies. The initial step in diagnosing this condition is taking a detailed medical history, including symptoms such as fatigue, jaundice, and dark urine. Physical examination may reveal signs such as pallor, enlarged spleen, or jaundice, which can provide important clues to the underlying cause of the anaemia.
Laboratory tests play a vital role in the diagnosis of Acquired Haemolytic Anaemia. A complete blood count (CBC) can show low levels of red blood cells, hemoglobin, and hematocrit, indicating anaemia. Blood smear examination may reveal abnormal red blood cell morphology, such as spherocytes or schistocytes, which are characteristic of immune-mediated haemolysis. Other tests, such as reticulocyte count, Coombs test, and LDH levels, can help differentiate between different types of haemolytic anaemia.
Imaging studies, such as ultrasound or CT scans, may be used in some cases to evaluate the size and structure of the spleen, which can be enlarged in immune-mediated haemolytic anaemia. These tests can also help identify any underlying causes of the anaemia, such as autoimmune disorders or malignancies. Additionally, bone marrow biopsy may be performed to evaluate the production of red blood cells and rule out other potential causes of haemolysis. Overall, a comprehensive approach combining clinical evaluation, laboratory tests, and imaging studies is essential for an accurate diagnosis of Acquired Haemolytic Anaemia, Immune (3A20).
💊 Treatment & Recovery
Treatment for 3A20, acquired hemolytic anemia, immune, usually involves addressing the underlying cause and managing symptoms to improve the patient’s quality of life. The primary goal of treatment is to reduce the destruction of red blood cells by the immune system. For mild cases, no treatment may be necessary, but more severe cases may require medications such as corticosteroids to suppress the immune response and prevent further destruction of red blood cells.
In some cases, patients with acquired hemolytic anemia may require blood transfusions to replace the red blood cells that have been destroyed. This can help relieve symptoms such as fatigue, weakness, and shortness of breath. However, blood transfusions are typically a temporary solution and may not address the underlying cause of the anemia.
For patients with severe or refractory acquired hemolytic anemia, other treatment options may include immunosuppressive therapy, splenectomy (surgical removal of the spleen), or bone marrow transplant. These treatments are typically reserved for cases that do not respond to more conservative measures and may carry additional risks and complications. It is important for patients to work closely with their healthcare providers to determine the most appropriate treatment plan for their individual circumstances and to monitor their response to treatment closely.
🌎 Prevalence & Risk
In the United States, acquired immune hemolytic anemia (AIHA) is a rare disease, with an estimated prevalence of 1-3 cases per 100,000 population. However, the actual prevalence may be higher due to underdiagnosis and underreporting. AIHA can occur at any age but is more common in adults, with a peak incidence in the fifth and sixth decades of life.
In Europe, the prevalence of AIHA is similar to that in the United States, with an estimated 1-3 cases per 100,000 population. Like in the United States, AIHA is more common in adults, with a peak incidence in the fifth and sixth decades of life. However, there may be variability in prevalence rates among different European countries due to differences in diagnostic practices and genetic predisposition.
In Asia, the prevalence of AIHA is relatively lower compared to the United States and Europe, with an estimated 0.5-1 cases per 100,000 population. AIHA is less commonly reported in Asian populations, with a lower incidence in adults compared to Western countries. However, similar to other regions, there may be underdiagnosis and underreporting of AIHA in Asia due to lack of awareness and limited access to healthcare services.
In Africa, limited data is available on the prevalence of AIHA, but it is believed to be lower compared to other regions. AIHA may be underrecognized and underreported in Africa, with challenges in diagnosis and access to healthcare services contributing to the lack of prevalence data. Further research is needed to better understand the epidemiology of AIHA in Africa and other regions with limited data.
😷 Prevention
One way to prevent 3A20 (Acquired haemolytic anaemia, immune) is to avoid known triggers that can lead to the development of immune-mediated haemolytic anaemia. These triggers can include certain medications, infections, autoimmune diseases, and exposure to toxins. By managing and minimizing exposure to these triggers, the risk of developing immune haemolytic anaemia can be reduced.
In cases where immune-mediated haemolytic anaemia is secondary to an underlying condition, such as an autoimmune disease or cancer, it is important to effectively manage and treat the primary disease. By properly managing the underlying condition, the risk of developing secondary immune haemolytic anaemia can be decreased. This may involve regular monitoring, medication management, and coordination of care with healthcare providers.
For individuals with a history of immune-mediated haemolytic anaemia or other autoimmune disorders, it is important to maintain regular follow-up appointments with a healthcare provider. By monitoring blood counts, symptoms, and overall health status on a regular basis, early signs of haemolysis can be detected and appropriate interventions can be implemented. This proactive approach can help prevent complications and improve outcomes for individuals at risk for immune-mediated haemolytic anaemia.
