ICD-11 code 3A10.00, also known as Haemolytic anaemia due to glucose-6-phosphate dehydrogenase deficiency, is a specific medical code used to classify cases where individuals experience decreased red blood cell lifespan due to a genetic enzyme deficiency. This condition occurs when the body lacks sufficient levels of glucose-6-phosphate dehydrogenase, an enzyme responsible for protecting red blood cells from oxidative damage. Without this protective enzyme, red blood cells become fragile and are easily destroyed, leading to anaemia.
People with glucose-6-phosphate dehydrogenase deficiency may experience symptoms such as fatigue, pale skin, dark urine, jaundice, and shortness of breath. In severe cases, individuals may develop acute hemolytic anemia, a condition where red blood cells are rapidly destroyed, leading to potentially life-threatening complications. This condition can be triggered by certain medications, infections, or exposure to certain foods or substances that cause oxidative stress on red blood cells in people with G6PD deficiency. Treatment for haemolytic anaemia due to glucose-6-phosphate dehydrogenase deficiency typically involves managing symptoms, avoiding triggers, and in some cases, blood transfusions.

The SNOMED CT code equivalent to ICD-11 code 3A10.00 is 87457004. This code specifically refers to the condition of haemolytic anaemia due to glucose-6-phosphate dehydrogenase deficiency. SNOMED CT, an extensive clinical terminology system, categorizes various medical conditions with unique codes for standardized documentation and data exchange purposes. In this case, the code 87457004 provides a precise way to identify and track cases of haemolytic anaemia resulting from a deficiency in the enzyme glucose-6-phosphate dehydrogenase. The use of SNOMED CT codes helps streamline communication between healthcare providers, researchers, and other stakeholders, ensuring accurate and efficient management of patient information related to this particular medical condition.
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 3A10.00, or Haemolytic anaemia due to glucose-6-phosphate dehydrogenase deficiency, may present with a variety of symptoms indicative of hemolytic anemia. Common symptoms include fatigue, weakness, and shortness of breath. These manifestations are the result of the destruction of red blood cells, leading to decreased oxygen-carrying capacity in the bloodstream.
Some individuals with 3A10.00 may also experience jaundice, which is characterized by a yellowing of the skin and eyes. Jaundice occurs as a result of the accumulation of bilirubin, a byproduct of red blood cell breakdown, in the body. This symptom is often a key indicator of hemolysis in individuals with glucose-6-phosphate dehydrogenase deficiency.
In severe cases of hemolytic anemia due to glucose-6-phosphate dehydrogenase deficiency, individuals may develop complications such as splenomegaly, or enlargement of the spleen. Splenomegaly can result from the increased workload of the spleen in removing damaged red blood cells from circulation. This enlargement may cause discomfort or pain in the upper left abdomen and can lead to further complications if left untreated.
🩺 Diagnosis
Diagnosis methods for 3A10.00, Haemolytic Anaemia due to Glucose-6-Phosphate Dehydrogenase Deficiency, involve a combination of clinical evaluation, laboratory tests, and genetic analysis. Patients suspected of having G6PD deficiency may present with symptoms such as jaundice, dark urine, fatigue, and pallor.
A complete blood count (CBC) is often the initial test performed to evaluate for haemolytic anaemia and to assess for any abnormalities in red blood cell count, hemoglobin level, and hematocrit. Peripheral blood smear examination can reveal the presence of bite cells, Heinz bodies, and spherocytes, which are characteristic findings in G6PD deficiency.
A definitive diagnosis of G6PD deficiency is typically made through enzyme activity testing. This involves measuring the levels of G6PD enzyme in red blood cells, either by quantitative spectrophotometric analysis or a qualitative fluorescent spot test. Genetic testing can also be performed to identify specific mutations in the G6PD gene that are associated with the deficiency. Additionally, hemoglobin electrophoresis may be done to rule out other types of anaemia that may mimic the clinical presentation of G6PD deficiency.
💊 Treatment & Recovery
Treatment for Haemolytic Anaemia due to Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency involves managing the underlying cause of the condition. This typically includes avoiding triggers that can lead to hemolysis, such as certain medications or foods. Patients are advised to stay well-hydrated and maintain a healthy diet to support red blood cell production.
In severe cases of G6PD deficiency, blood transfusions may be necessary to replace the damaged red blood cells. This is usually reserved for individuals with significant symptoms or complications of hemolysis. Additionally, folic acid supplements may be prescribed to support red blood cell production and prevent complications of anemia.
Recovery from Haemolytic Anaemia due to G6PD deficiency varies depending on the severity of the condition and how well the triggers are managed. With proper treatment and lifestyle modifications, many individuals with this condition can live healthy lives. It is important for patients to follow their healthcare provider’s recommendations, avoid triggers that can lead to hemolysis, and monitor their red blood cell counts regularly.
🌎 Prevalence & Risk
In the United States, the prevalence of 3A10.00 (Haemolytic anaemia due to glucose-6-phosphate dehydrogenase deficiency) varies among different ethnic groups. It is more common among individuals of African, Asian, and Mediterranean descent compared to those of Northern European descent. Studies have shown that the overall prevalence of glucose-6-phosphate dehydrogenase deficiency in the US population is estimated to be around 10-15%.
In Europe, the prevalence of 3A10.00 is influenced by the genetic background of the population. Glucose-6-phosphate dehydrogenase deficiency is more commonly found in regions with a higher prevalence of malaria, such as in Southern Europe. Studies have reported that the overall prevalence of glucose-6-phosphate dehydrogenase deficiency in Europe ranges from 0.1% to 19%, depending on the country and ethnic composition of the population.
In Asia, the prevalence of 3A10.00 varies widely across different countries and regions. Glucose-6-phosphate dehydrogenase deficiency is more common in areas where malaria is endemic, such as Southeast Asia and the Indian subcontinent. Studies have shown that the prevalence of glucose-6-phosphate dehydrogenase deficiency in Asia ranges from 2% to 20%, with higher rates reported in certain populations.
In Africa, the prevalence of 3A10.00 is highest among populations living in malaria-endemic regions. Glucose-6-phosphate dehydrogenase deficiency is common in sub-Saharan Africa, where the disease burden of malaria is high. Studies have reported that the prevalence of glucose-6-phosphate dehydrogenase deficiency in Africa ranges from 2% to 30%, with higher rates found in certain ethnic groups.
😷 Prevention
To prevent 3A10.00 (Haemolytic anaemia due to glucose-6-phosphate dehydrogenase deficiency), it is essential to take precautions to avoid triggering hemolysis in individuals with this condition. One key preventive measure is to identify and avoid known triggers of hemolysis, such as certain medications (e.g., antimalarial drugs, sulfonamides, dapsone) and certain foods (e.g., fava beans). By carefully monitoring medications and dietary intake, individuals with glucose-6-phosphate dehydrogenase deficiency can minimize the risk of hemolytic crises.
Another important aspect of prevention is to educate patients with glucose-6-phosphate dehydrogenase deficiency about the condition and its potential triggers. By raising awareness about the risks associated with certain medications and foods, individuals with this deficiency can make informed choices to protect their health. Healthcare providers should also be aware of the patient’s condition and take appropriate precautions when prescribing medications or recommending dietary changes.
Regular monitoring of blood counts and enzyme levels can help identify early signs of hemolysis in individuals with glucose-6-phosphate dehydrogenase deficiency. By closely monitoring these parameters, healthcare providers can intervene promptly if any abnormalities are detected, potentially preventing a hemolytic crisis. Additionally, maintaining overall good health through a balanced diet, regular exercise, and avoidance of smoking can help reduce the risk of complications in individuals with this condition.
🦠 Similar Diseases
One disease similar to 3A10.00 is autoimmune hemolytic anemia, coded as D59.1 in the International Classification of Diseases, Tenth Revision (ICD-10). This condition occurs when the body’s immune system mistakenly attacks its own red blood cells, leading to their destruction and causing anemia. While the underlying cause of autoimmune hemolytic anemia differs from G6PD deficiency, both conditions can result in the same symptom of hemolytic anemia.
Another related disease is hereditary spherocytosis, which is coded as D58.0 in the ICD-10. In hereditary spherocytosis, the red blood cells have a spherical shape rather than the normal disc shape, which can make them more prone to premature destruction. Like G6PD deficiency, hereditary spherocytosis can lead to hemolytic anemia due to the increased breakdown of red blood cells.
A third disease comparable to 3A10.00 is sickle cell disease, categorized as D57.0 in the ICD-10. Sickle cell disease is a genetic disorder that causes red blood cells to become rigid and sickle-shaped, leading to various complications, including hemolytic anemia. While the underlying genetic mutations differ between sickle cell disease and G6PD deficiency, both conditions can result in the destruction of red blood cells and subsequent anemia.
