ICD-11 code 3A01.2 refers to Vitamin B12 deficiency anemia due to low intake. This code is used to classify cases where a person develops anemia specifically because they have not been consuming enough Vitamin B12 in their diet.
Anemia is a condition characterized by a lack of healthy red blood cells in the body, which can lead to symptoms such as fatigue, weakness, and shortness of breath. Vitamin B12 is essential for the production of red blood cells, so a deficiency in this vitamin can result in anemia.
Low intake of Vitamin B12 can occur for various reasons, such as a vegetarian or vegan diet that lacks sources of this vitamin found in animal products like meat, dairy, and eggs. Other factors that can contribute to low intake of Vitamin B12 include malabsorption disorders, certain medications, and aging.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to the ICD-11 code 3A01.2 is 441030002 (Vitamin B12 deficiency anemia due to dietary cause). This specific code indicates a diagnosis of anemia resulting from low intake of vitamin B12. Vitamin B12 is an essential nutrient that plays a critical role in the production of red blood cells. When there is a deficiency of vitamin B12 in the body, it can lead to anemia due to the inability to produce enough healthy red blood cells.
Healthcare professionals can use the SNOMED CT code 441030002 to accurately document cases of vitamin B12 deficiency anemia caused by low intake in electronic health records. This code helps in tracking and monitoring patient diagnoses, treatments, and outcomes related to this specific type of anemia. By utilizing the SNOMED CT system, healthcare providers can ensure standardized and consistent coding practices, leading to improved communication and understanding of patients’ health conditions.
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 3A01.2 (Vitamin B12 deficiency anemia due to low intake) may present gradually, making it challenging to diagnose in its early stages. One of the most common symptoms is fatigue, as the body struggles to produce enough red blood cells to carry oxygen throughout the body. Patients may also experience weakness, shortness of breath, and lightheadedness, all of which are indicative of anemia.
In addition to the physical symptoms, individuals with Vitamin B12 deficiency anemia due to low intake may also experience neurological symptoms. These can include tingling or numbness in the hands and feet, difficulty walking, and cognitive impairment. Some patients may even develop depression, confusion, or memory problems as a result of the deficiency affecting the nervous system.
Furthermore, the development of a swollen, inflamed tongue (glossitis) is another common symptom of 3A01.2. This condition can cause the tongue to appear beefy and smooth, potentially leading to difficulty swallowing or speaking. In severe cases, glossitis may also result in mouth ulcers or a burning sensation on the tongue, further complicating the patient’s ability to eat and maintain proper nutrition.
🩺 Diagnosis
Diagnosis of Vitamin B12 deficiency anemia due to low intake typically begins with a detailed medical history and physical examination. The healthcare provider may inquire about dietary habits, symptoms, and possible risk factors for malabsorption. Physical signs such as pallor, jaundice, and glossitis may be indicative of anemia.
Laboratory tests are essential in confirming the diagnosis of Vitamin B12 deficiency anemia. A complete blood count (CBC) may reveal characteristic findings such as macrocytic anemia, low red blood cell counts, and elevated mean corpuscular volume (MCV). Additionally, a peripheral blood smear may show hypersegmented neutrophils, a common finding in B12 deficiency.
Serum Vitamin B12 levels are crucial in diagnosing deficiency. Low levels of Vitamin B12 in the blood can support the diagnosis of Vitamin B12 deficiency anemia due to low intake. However, it is important to note that serum B12 levels may not always correlate with clinical symptoms, especially in cases of early or mild deficiency.
In some cases, additional tests such as methylmalonic acid (MMA) and homocysteine levels may be measured to further evaluate Vitamin B12 deficiency. Elevated levels of MMA and homocysteine are markers of functional B12 deficiency and can help confirm the diagnosis. It is essential for healthcare providers to interpret laboratory results in the context of clinical symptoms to provide an accurate diagnosis and appropriate management for patients with Vitamin B12 deficiency anemia due to low intake.
💊 Treatment & Recovery
Treatment for Vitamin B12 deficiency anemia due to low intake typically involves supplementing with Vitamin B12. This can be done through oral supplements, intramuscular injections, or nasal sprays, depending on the severity of the deficiency. Increasing consumption of Vitamin B12-rich foods such as meat, fish, eggs, and dairy products can also help in the recovery process.
In some cases, a doctor may recommend a temporary diet change to include fortified foods or supplements that are high in Vitamin B12. This is especially important for individuals who follow a strict vegetarian or vegan diet, as plant-based sources of Vitamin B12 are limited. It is crucial to adhere to the recommended treatment plan and follow up with regular check-ups to monitor progress and ensure that the deficiency is being properly addressed.
Recovery from Vitamin B12 deficiency anemia due to low intake can take several weeks to months, depending on the severity of the deficiency and the individual’s response to treatment. Symptoms such as fatigue, weakness, and shortness of breath may improve gradually as the body’s Vitamin B12 levels are restored. It is essential to maintain a balanced diet rich in Vitamin B12 and to follow any additional recommendations provided by a healthcare provider to prevent a recurrence of the deficiency.
🌎 Prevalence & Risk
Prevalence in the United States of 3A01.2 (Vitamin B12 deficiency anemia due to low intake) is estimated to be around 3% to 6% in the general population. This condition is more common among older adults, individuals with gastrointestinal disorders, and those following vegetarian or vegan diets. Vitamin B12 deficiency can lead to various health complications if left untreated, making it essential for timely diagnosis and intervention.
In Europe, the prevalence of Vitamin B12 deficiency anemia due to low intake varies across different countries. Various factors such as dietary habits, age demographics, and socioeconomic status can influence the incidence of this condition.

🦠 Similar Diseases
One disease similar to 3A01.2 is pernicious anemia (ICD-10 code D51.0). Pernicious anemia is a type of megaloblastic anemia caused by a lack of intrinsic factor, a protein needed to absorb vitamin B12. Without sufficient intrinsic factor, vitamin B12 cannot be absorbed properly in the digestive tract, leading to a deficiency and resulting in symptoms such as fatigue, weakness, and shortness of breath.
Another related disease is food-cobalamin malabsorption (ICD-10 code E53.8). Food-cobalamin malabsorption is a condition in which the body is unable to properly absorb vitamin B12 from food sources. This can occur due to a lack of intrinsic factor or other underlying conditions that prevent the absorption of the vitamin. Symptoms of B12 deficiency in this case may include anemia, neuropathy, and cognitive impairments.
Additionally, a disease comparable to 3A01.2 is malabsorption of vitamin B12, not elsewhere classified (ICD-10 code K90.3). Malabsorption of vitamin B12 can occur due to various digestive disorders that impair the body’s ability to absorb the vitamin from food sources. Conditions such as Crohn’s disease, celiac disease, and gastric surgery can all lead to malabsorption of vitamin B12, resulting in deficiency and symptoms like anemia, fatigue, and neurological issues.
