ICD-11 code 3A03.40 refers to acquired pyridoxine deficiency anemia, a type of anemia caused by insufficient levels of vitamin B6 in the body. It is classified as a nutritional deficiency anemia, which means that the lack of vitamin B6 in the diet or the body’s inability to absorb it properly leads to decreased red blood cell production and subsequent anemia.
Acquired pyridoxine deficiency anemia can occur due to various factors, such as chronic alcoholism, diets low in vitamin B6-rich foods, certain medications that interfere with vitamin B6 absorption, or medical conditions that impair vitamin B6 metabolism. Symptoms of this type of anemia may include fatigue, weakness, pale skin, dizziness, shortness of breath, and irregular heartbeats. Diagnosis typically involves blood tests to measure levels of red blood cells, hemoglobin, and vitamin B6 in the body.
Treatment for acquired pyridoxine deficiency anemia usually involves increasing dietary intake of vitamin B6 through foods like poultry, fish, potatoes, bananas, and fortified cereals, or taking vitamin B6 supplements if necessary. In some cases, underlying medical conditions contributing to the deficiency may need to be addressed to effectively manage the anemia. Early detection and treatment of acquired pyridoxine deficiency anemia are important to prevent complications and improve overall health outcomes for affected individuals.

#️⃣ Coding Considerations
SNOMED CT code 421363000 corresponds to the ICD-11 code 3A03.40, which represents acquired pyridoxine deficiency anemia. This code is specifically used to denote cases in which a deficiency in vitamin B6 (pyridoxine) leads to a decrease in red blood cell production, resulting in anemia. Health care professionals use this code to accurately diagnose and classify patients who present with symptoms of fatigue, weakness, and pale skin due to pyridoxine deficiency. By utilizing this SNOMED CT code, medical providers can better communicate and share information about patients with acquired pyridoxine deficiency anemia, ensuring that appropriate treatment and management strategies are implemented promptly.
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
Acquired pyridoxine deficiency anemia (3A03.40) is a condition characterized by a deficiency of vitamin B6, also known as pyridoxine. This essential nutrient is crucial for the production of red blood cells and other functions in the body. Symptoms of this type of anemia can vary in severity and may include fatigue, weakness, pale skin, shortness of breath, and dizziness.
One of the hallmark symptoms of acquired pyridoxine deficiency anemia is a decrease in the body’s ability to produce enough healthy red blood cells. This can lead to anemia, a condition in which the blood does not have enough red blood cells to carry oxygen to the body’s tissues. As a result, individuals with this condition may experience symptoms such as weakness, fatigue, and shortness of breath, particularly during physical activity.
In addition to symptoms related to anemia, individuals with acquired pyridoxine deficiency anemia may also experience other signs of vitamin B6 deficiency. These can include dermatitis, confusion, irritability, and seizures. In severe cases, nerve damage and cognitive impairment may also occur. It is important for individuals experiencing these symptoms to seek medical attention to determine the underlying cause and receive appropriate treatment.
🩺 Diagnosis
Diagnosis of Acquired pyridoxine deficiency anaemia typically involves a thorough medical history assessment to identify potential risk factors such as malabsorption disorders, excessive alcohol intake, certain medications, or a diet deficient in vitamin B6. Symptoms such as fatigue, weakness, irritability, and pallor may prompt further investigation. Laboratory tests commonly used to diagnose this condition include a complete blood count to identify anemia and a vitamin B6 blood test to measure pyridoxine levels. Additionally, a peripheral blood smear may reveal red blood cell abnormalities characteristic of vitamin B6 deficiency.
Further diagnostic procedures may involve measuring levels of homocysteine and methylmalonic acid in the blood, as elevated levels of these substances are indicative of a vitamin B6 deficiency. Bone marrow examination may be necessary in some cases to assess erythropoiesis and rule out other causes of anemia. It is important for healthcare providers to consider potential underlying conditions that may contribute to acquired pyridoxine deficiency anaemia, such as autoimmune diseases, kidney disease, or certain medications that interfere with vitamin B6 absorption.
In addition to laboratory tests, imaging studies such as ultrasounds or endoscopies may be performed to assess the gastrointestinal tract for signs of malabsorption disorders. Genetic testing may also be considered to identify any hereditary factors contributing to the development of vitamin B6 deficiency. Overall, a comprehensive diagnostic approach involving thorough evaluation of medical history, physical examination, laboratory tests, and potential imaging studies is essential for accurate diagnosis and treatment of Acquired pyridoxine deficiency anaemia.
💊 Treatment & Recovery
Treatment for 3A03.40, acquired pyridoxine deficiency anemia, typically involves oral supplementation of pyridoxine, also known as vitamin B6. This can help to restore depleted levels of pyridoxine in the body and alleviate symptoms associated with the deficiency. The recommended daily allowance of pyridoxine for adults is between 1.3 to 1.7 milligrams.
In cases of severe anemia or malabsorption issues, intravenous administration of pyridoxine may be necessary to ensure adequate absorption of the vitamin. This method bypasses the digestive system and delivers a higher concentration of pyridoxine directly into the bloodstream. Close monitoring of blood levels and symptoms is essential to determine the effectiveness of the treatment and make adjustments as needed.
Recovery from acquired pyridoxine deficiency anemia depends on the individual’s response to treatment and the underlying cause of the deficiency. With prompt diagnosis and appropriate management, most patients experience a significant improvement in symptoms within a few weeks of starting treatment. Adherence to a balanced diet rich in pyridoxine-containing foods, such as poultry, fish, and nuts, can help prevent future deficiencies and support overall health and well-being. Regular follow-up visits with a healthcare provider are essential to monitor progress and adjust treatment as necessary.
🌎 Prevalence & Risk
In the United States, acquired pyridoxine deficiency anemia, coded as 3A03.40, is a rare condition with limited data on its prevalence. Due to better access to healthcare and diverse dietary habits, the incidence of this type of anemia is relatively low compared to other regions.
In Europe, the prevalence of acquired pyridoxine deficiency anemia is also considered to be low. However, certain populations within Europe may be at higher risk due to factors such as malnutrition, alcoholism, or certain medical conditions that interfere with vitamin B6 absorption or metabolism.
