ICD-11 code 3A03.42 refers to acquired thiamine deficiency anemia, a condition characterized by a lack of thiamine, also known as vitamin B1, in the body. Thiamine plays a critical role in energy production and the functioning of the nervous system. When there is a deficiency of thiamine, it can lead to anemia, which is a condition where there is a decrease in the number of red blood cells or hemoglobin levels in the blood.
Acquired thiamine deficiency anemia can result from various factors, including inadequate dietary intake of thiamine, malabsorption of thiamine from the gastrointestinal tract, or increased thiamine requirements in conditions such as pregnancy or chronic alcoholism. Symptoms of acquired thiamine deficiency anemia may include fatigue, weakness, shortness of breath, and palpitations. In severe cases, it can lead to neurological symptoms such as confusion, memory problems, and muscle weakness.
Treatment for acquired thiamine deficiency anemia typically involves thiamine supplementation either orally or intravenously, depending on the severity of the deficiency. In cases where the deficiency is due to alcoholism, addressing the underlying cause, such as alcohol cessation, is also important to prevent further complications. Regular monitoring of thiamine levels and blood counts is essential to ensure adequate treatment and prevent recurrence of anemia.

This allows for better coordination of care and improved patient outcomes. It is essential for healthcare professionals to be familiar with both ICD-11 and SNOMED CT codes to effectively document and communicate patient information.
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 Acquired thiamine deficiency anaemia, also known as 3A03.42, typically manifest in individuals who have a deficiency in thiamine, also known as vitamin B1. Thiamine plays a crucial role in various bodily functions, including the metabolism of carbohydrates and the production of energy. When levels of thiamine are low, the body may experience a range of symptoms indicative of anemia.
One common symptom of Acquired thiamine deficiency anaemia is fatigue. Individuals may feel unusually tired or lethargic, even after getting adequate rest. This fatigue may persist despite efforts to improve sleep quality or increase physical activity levels, making daily tasks feel more challenging.
Another symptom of Acquired thiamine deficiency anaemia is weakness. Individuals may notice a decrease in muscle strength or endurance, making it difficult to carry out physical activities or maintain a consistent level of performance. This weakness may be accompanied by muscle cramps or spasms, particularly during periods of increased physical exertion.
In addition to fatigue and weakness, individuals with Acquired thiamine deficiency anaemia may experience dizziness or lightheadedness. These symptoms may occur when standing up too quickly or after prolonged periods of sitting or lying down. In severe cases, dizziness may lead to fainting or feeling faint, requiring medical attention to address the underlying thiamine deficiency.
🩺 Diagnosis
Diagnosis methods for 3A03.42, also known as acquired thiamine deficiency anemia, often involve a combination of clinical evaluation, laboratory tests, and medical history review. Patients presenting with symptoms such as fatigue, weakness, shortness of breath, and pale skin may undergo a physical examination to assess indicators of anemia, such as rapid heart rate and low blood pressure.
Laboratory tests play a crucial role in diagnosing acquired thiamine deficiency anemia by measuring the levels of thiamine, red blood cells, hemoglobin, and hematocrit in the blood. A complete blood count (CBC) can help identify low red blood cell counts and hemoglobin levels characteristic of anemia. Additionally, a blood smear may reveal abnormal red blood cell morphology, such as macrocytic or megaloblastic changes, indicative of a thiamine deficiency.
Further diagnostic tests may be recommended to confirm the suspected thiamine deficiency anemia and identify underlying causes, such as malnutrition or alcohol abuse. Blood tests measuring thiamine levels directly can provide valuable information on the patient’s thiamine status, while other tests, such as a bone marrow biopsy, may be performed to rule out other potential causes of anemia. In some cases, imaging studies, such as a CT scan or MRI, may be ordered to assess the extent of organ damage associated with chronic thiamine deficiency.
💊 Treatment & Recovery
Treatment for 3A03.42 (Acquired thiamine deficiency anemia) involves supplementing thiamine through oral or intravenous routes. Thiamine supplements are readily available and can be administered at varying doses depending on the severity of the deficiency. In cases of severe deficiency, intravenous thiamine is recommended to ensure rapid absorption and distribution in the body.
In addition to thiamine supplementation, individuals with acquired thiamine deficiency anemia may also require treatment for any underlying conditions that may have contributed to the deficiency. This may involve addressing dietary deficiencies, treating alcohol use disorder, or managing any other conditions that may affect thiamine absorption or utilization.
Recovery from acquired thiamine deficiency anemia typically occurs within a few weeks of initiating treatment. Symptoms such as fatigue, weakness, and anemia can improve with thiamine supplementation and resolution of the underlying deficiency. Regular monitoring of thiamine levels may be necessary to ensure adequate levels are maintained and to prevent recurrence of the deficiency. Following treatment, individuals may be advised to maintain a balanced diet rich in thiamine to support ongoing health and prevent future deficiencies.
🌎 Prevalence & Risk
In the United States, the prevalence of acquired thiamine deficiency anemia (3A03.42) is fairly low compared to other regions. This type of anemia is most commonly seen in individuals with alcohol use disorder, malabsorption disorders, or those who are severely malnourished. Despite the relatively low prevalence, healthcare providers should remain vigilant in recognizing and treating this condition, as it can have serious consequences if left untreated.
In Europe, acquired thiamine deficiency anemia is also relatively uncommon. However, certain populations may be at higher risk, such as individuals with a history of chronic alcohol use or those with underlying medical conditions that impair thiamine absorption. Although the prevalence may vary among different European countries, awareness of this type of anemia and its risk factors is important for healthcare professionals in order to provide timely diagnosis and treatment.
In Asia, the prevalence of acquired thiamine deficiency anemia is higher compared to the United States and Europe. This is likely due to differences in dietary patterns, as well as higher rates of certain medical conditions associated with thiamine deficiency. Healthcare providers in Asian countries should be aware of the prevalence of this condition and consider screening individuals at risk, such as those with chronic alcohol use or malabsorption disorders, in order to prevent potential complications.
In Africa, acquired thiamine deficiency anemia may also be more prevalent compared to other regions, particularly in areas with high rates of malnutrition and inadequate access to healthcare. This underscores the importance of public health initiatives aimed at improving nutrition and increasing awareness of thiamine deficiency in order to reduce the burden of this type of anemia in African populations. Healthcare providers in these regions should be knowledgeable about the risk factors for acquired thiamine deficiency anemia and be prepared to diagnose and treat this condition in their patients.
😷 Prevention
To prevent Acquired thiamine deficiency anemia (3A03.42), it is important to ensure an adequate intake of thiamine, also known as Vitamin B1. Thiamine is essential for the body to convert carbohydrates into energy, and a deficiency can lead to various health issues, including anemia.
One way to prevent acquired thiamine deficiency anemia is to consume a balanced diet that includes foods rich in thiamine. Good sources of thiamine include whole grains, nuts and seeds, lean meats, and fortified cereals. Incorporating these foods into your daily meals can help ensure you are getting enough thiamine to prevent deficiency.
Another important preventive measure is to limit alcohol consumption, as excessive alcohol intake can lead to thiamine deficiency. Alcohol interferes with the absorption and utilization of thiamine in the body, which can increase the risk of developing deficiency-related conditions, including anemia. If you consume alcohol, it is essential to do so in moderation and to make sure you are still meeting your thiamine requirements through your diet.
