ICD-11 code 3A2Z refers to acquired haemolytic anaemia, unspecified. This code is used to classify cases in which there is destruction of red blood cells due to an acquired cause, such as certain medications, infections, or autoimmune disorders. Haemolytic anaemia is a condition characterized by the premature destruction of red blood cells, leading to a shortage of these essential cells in the bloodstream.
Acquired haemolytic anaemia can present with symptoms such as fatigue, weakness, pale skin, jaundice, and an enlarged spleen. The underlying cause of the condition must be identified in order to guide appropriate treatment and management strategies. Acquired haemolytic anaemia can be diagnosed through blood tests, including a complete blood count and tests to detect antibodies or other markers of immune destruction of red blood cells.
The unspecified designation in ICD-11 code 3A2Z indicates that the specific cause of the acquired haemolytic anaemia has not been identified or specified. This may be due to a lack of information or diagnostic clarity at the time of coding. Further testing and evaluation may be necessary to determine the precise etiology of the condition in order to optimize patient care and outcomes.

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
Individuals with 3A2Z (Acquired haemolytic anaemia, unspecified) may present with a variety of symptoms indicative of anemia, such as fatigue, weakness, and pallor. These symptoms stem from the body’s decreased ability to transport oxygen efficiently due to a reduced number of red blood cells, which are responsible for carrying oxygen to tissues.
Some common symptoms of acquired hemolytic anemia, regardless of etiology, include jaundice, dark urine, and an enlarged spleen. Jaundice occurs due to the excessive breakdown of red blood cells, leading to the accumulation of bilirubin in the blood and tissues. Dark urine is a result of the high levels of bilirubin being excreted by the kidneys, giving urine a darker color than usual. An enlarged spleen is observed in individuals with hemolytic anemia as the spleen works overtime to remove damaged red blood cells from circulation.
In severe cases of 3A2Z, patients may experience symptoms of acute hemolytic crisis, characterized by sudden and severe worsening of anemia. Symptoms of an acute hemolytic crisis include rapid heartbeat, shortness of breath, chest pain, and confusion. This medical emergency requires immediate attention and treatment to prevent life-threatening complications. Individuals with 3A2Z should seek medical evaluation if they experience any of these symptoms or have concerns about their condition.
🩺 Diagnosis
Diagnosis of acquired hemolytic anemia, unspecified, involves a thorough medical history and physical examination to identify any potential underlying causes or risk factors. Laboratory tests are essential for confirming the diagnosis and determining the severity of the condition. These tests typically include a complete blood count (CBC) to assess red blood cell count, hemoglobin levels, and hematocrit, as well as a reticulocyte count to evaluate the production of new red blood cells.
Additional blood tests may be performed to assess markers of hemolysis, such as lactate dehydrogenase (LDH), haptoglobin, and bilirubin levels. Direct and indirect Coombs tests can help identify the presence of antibodies on red blood cells, which can indicate immune-mediated hemolysis. Furthermore, a peripheral blood smear may be examined under a microscope to assess for abnormal red blood cell morphology, such as spherocytes or schistocytes, which can suggest hemolytic anemia.
In some cases, further testing may be needed to determine the underlying cause of acquired hemolytic anemia. This may include autoimmune testing to check for specific antibodies or autoimmune disorders, as well as imaging studies, such as ultrasound or CT scans, to evaluate the spleen and other organs that play a role in red blood cell clearance. A bone marrow biopsy may also be performed to assess for any abnormalities in red blood cell production or maturation. Overall, diagnosis of 3A2Z requires a comprehensive approach to accurately identify and manage the underlying cause of acquired hemolytic anemia.
💊 Treatment & Recovery
Treatment for 3A2Z, or acquired haemolytic anaemia, unspecified, depends on the underlying cause of the condition. In cases where the anaemia is caused by an autoimmune reaction, corticosteroids may be prescribed to suppress the immune response and reduce the destruction of red blood cells. In severe cases, immunosuppressant medications may be used to further suppress the immune system.
In cases where the anaemia is caused by medications or toxins, the offending agent may be removed or discontinued to prevent further destruction of red blood cells. Patients may also require supportive care such as blood transfusions to replace the lost red blood cells and alleviate symptoms of anaemia. Intravenous fluids may also be administered to help maintain hydration and support overall health.
Recovery from 3A2Z, acquired haemolytic anaemia, unspecified, can vary depending on the severity of the condition and the effectiveness of treatment. In some cases, patients may experience a gradual improvement in their symptoms as the underlying cause of the anaemia is addressed. However, in more severe cases, long-term management may be required to prevent relapses and complications. Follow-up care with a healthcare provider is important to monitor progress and adjust treatment as needed.
🌎 Prevalence & Risk
In the United States, the prevalence of 3A2Z (Acquired haemolytic anaemia, unspecified) is estimated to be around 1-3 cases per 100,000 people. This condition is more commonly seen in adults, but can also affect children. It is important to note that the prevalence may vary depending on factors such as age, gender, and overall health of the population.
In Europe, the prevalence of 3A2Z is slightly higher than in the United States, with approximately 2-4 cases per 100,000 people. This region has a higher overall incidence of haemolytic anaemia compared to other parts of the world. The prevalence of 3A2Z may also be influenced by genetic factors and environmental exposures unique to the European population.
In Asia, the prevalence of 3A2Z is similar to that of Europe, with an estimated 2-4 cases per 100,000 people. However, there may be regional variations within Asia due to differences in healthcare resources and access to diagnostic tools. It is important for healthcare providers to be aware of the prevalence of 3A2Z in their specific region in order to provide appropriate care and management for affected individuals.
In Africa, the prevalence of 3A2Z is not well documented, but it is believed to be lower compared to other regions such as the United States and Europe. This could be attributed to challenges in accurate diagnosis and reporting of haemolytic anaemia cases in certain African countries.

😷 Prevention
To prevent 3A2Z, one must first understand the underlying causes of acquired haemolytic anaemia. This condition can be triggered by various factors such as autoimmune disorders, infections, certain medications, and exposure to toxins. Avoiding these triggers is essential in preventing the onset of acquired haemolytic anaemia.
Individuals with autoimmune disorders should work closely with their healthcare providers to manage their condition effectively. This may involve taking immunosuppressants or other medications to control the immune response that leads to haemolytic anaemia. Regular monitoring of the condition and adjusting treatment as necessary can help prevent exacerbation of symptoms.
In cases where acquired haemolytic anaemia is caused by infections, practicing good hygiene and taking preventative measures can reduce the risk of developing the condition. Vaccinations, proper handwashing, and avoiding exposure to individuals with contagious illnesses are important steps in preventing infection-related haemolytic anaemia. Additionally, seeking prompt treatment for any infections can help prevent complications that may lead to haemolytic anaemia.
Avoiding medications known to cause haemolytic anaemia is crucial in preventing drug-induced cases of the condition. Individuals should always inform their healthcare providers of any medications they are taking, including over-the-counter drugs and supplements, to avoid potential interactions or adverse effects. If a medication is found to be causing haemolytic anaemia, alternative treatment options should be explored to prevent further harm.
🦠 Similar Diseases
One possible related disease to 3A2Z (Acquired haemolytic anaemia, unspecified) is autoimmune hemolytic anemia (AIHA). AIHA is a condition in which the immune system mistakenly attacks the body’s red blood cells, leading to their destruction. This can result in symptoms such as fatigue, pale skin, jaundice, and an enlarged spleen.
Another similar disease is paroxysmal nocturnal hemoglobinuria (PNH). PNH is a rare acquired disorder in which red blood cells break down prematurely. This can lead to symptoms such as fatigue, shortness of breath, abdominal pain, and dark urine. PNH is caused by a mutation in the PIG-A gene, which affects the proteins on the surface of red blood cells.
Additionally, hereditary spherocytosis is a genetic disorder that can cause symptoms similar to acquired haemolytic anaemia. In hereditary spherocytosis, red blood cells are abnormally shaped and more prone to destruction. This can lead to symptoms such as jaundice, gallstones, and an enlarged spleen. Treatment for hereditary spherocytosis may involve blood transfusions, splenectomy, or medication to manage symptoms.
