ICD-11 code 3A02.4 refers to drug-induced folate deficiency anemia, a condition where the body lacks an adequate amount of folate due to the use of certain medications. Folate is essential for the production of red blood cells, and a deficiency can lead to symptoms such as fatigue, weakness, and shortness of breath.
This specific code is used by healthcare professionals to classify cases where folate deficiency anemia is directly caused by the side effects of medications. Common drugs that can lead to this condition include methotrexate, certain anticonvulsants, and antibiotics. It is important for healthcare providers to be aware of this code when documenting and treating patients with drug-induced folate deficiency anemia.
Using ICD-11 code 3A02.4 when diagnosing drug-induced folate deficiency anemia allows for accurate tracking of cases and proper identification of potential trends or patterns related to medication use. This coding system aids in effective communication among healthcare professionals and ensures that patients receive appropriate treatment for their condition.

#️⃣ Coding Considerations
In the world of medical coding, the equivalent SNOMED CT code for the ICD-11 code 3A02.4 (Drug-induced folate deficiency anaemia) is 168729007. This SNOMED CT code specifically refers to a diagnosis of drug-induced folate deficiency anemia, indicating a condition where a deficiency in folate is caused by a medication rather than a lack of dietary intake.
The use of standardized medical code sets like SNOMED CT ensures accurate and consistent communication and documentation of patient diagnoses across healthcare systems and providers. This allows for improved data sharing, research, and patient care coordination.
Healthcare professionals and billing specialists must be familiar with these code sets to accurately document and report patient diagnoses for billing, research, and quality improvement purposes. Ensuring proper coding compliance is essential for effective healthcare operations and reimbursement.
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 drug-induced folate deficiency anemia (3A02.4) typically manifest as signs of anemia, including fatigue, weakness, and shortness of breath. Patients may also exhibit symptoms such as paleness, dizziness, and headaches due to the decreased production of red blood cells resulting from a folate deficiency. Additionally, individuals with this condition may experience irritability, cognitive difficulties, and a decreased appetite.
Further symptoms of drug-induced folate deficiency anemia may include a sore, red tongue, as well as mouth sores and difficulty swallowing, known as glossitis. Patients may also develop gastrointestinal issues such as diarrhea, nausea, and weight loss, which can contribute to the overall malnutrition and anemia caused by the deficiency of folate. In severe cases, individuals may experience chest pain, palpitations, and cold extremities, indicating a more advanced stage of anemia and potential cardiovascular complications associated with the condition.
Other symptoms that may arise from drug-induced folate deficiency anemia include a yellowing of the skin and eyes, known as jaundice, which is caused by the breakdown of red blood cells and the inability of the body to produce enough new ones. Patients may also present with shortness of breath, especially during physical exertion, as the decreased oxygen-carrying capacity of the blood leads to inadequate oxygen delivery to tissues and organs. In some cases, individuals may exhibit neurological symptoms such as numbness or tingling in the extremities, confusion, and memory problems, due to the impact of folate deficiency on nerve function.
🩺 Diagnosis
Diagnosis of drug-induced folate deficiency anemia (3A02.4) typically begins with a thorough medical history evaluation. The healthcare provider will inquire about the patient’s current medications, including over-the-counter drugs and supplements, to identify any potential causes of folate deficiency. Additionally, symptoms such as weakness, fatigue, and pale skin may prompt further investigation.
Laboratory tests are crucial in diagnosing drug-induced folate deficiency anemia. A complete blood count (CBC) will often reveal characteristics of anemia, such as low red blood cell count and hemoglobin levels. A blood smear may show abnormal red blood cell shapes, which can be indicative of folate deficiency. Furthermore, measuring the levels of folate and vitamin B12 in the blood can help confirm the diagnosis.
In some cases, additional tests may be necessary to determine the underlying cause of drug-induced folate deficiency anemia. For instance, a bone marrow biopsy may be performed to assess the production of red blood cells in the bone marrow. Imaging tests, such as an abdominal ultrasound, can also be used to evaluate the health of the liver, which plays a crucial role in folate metabolism. Overall, a comprehensive diagnostic approach is essential in identifying and treating drug-induced folate deficiency anemia.
💊 Treatment & Recovery
Treatment for drug-induced folate deficiency anemia (3A02.4) typically involves identifying and discontinuing the offending drug responsible for the deficiency. Supplemental folic acid is often prescribed to replenish the depleted folate levels in the body. The recommended dosage of folic acid depends on the severity of the anemia and the underlying cause.
In cases where the drug-induced folate deficiency anemia is severe or not responding to oral supplements, intravenous (IV) administration of folic acid may be necessary. This method allows for faster absorption and higher bioavailability of the nutrient. Periodic monitoring of folate levels through blood tests is crucial to ensure the effectiveness of the treatment and to adjust the dosage as needed.
In addition to folic acid supplementation, a balanced diet rich in folate-containing foods such as leafy greens, citrus fruits, and legumes can help support the body’s recovery from drug-induced folate deficiency anemia. Patients may also benefit from dietary counseling to optimize their nutrient intake and improve overall nutritional status. It is essential to address any underlying conditions or contributing factors that may have led to the deficiency in the first place.
🌎 Prevalence & Risk
In the United States, drug-induced folate deficiency anaemia (3A02.4) is a relatively common condition among individuals taking certain medications known to interfere with folate absorption or metabolism. The prevalence of this condition varies depending on the specific drugs being used and the patient population. Studies have shown that drug-induced folate deficiency anaemia can occur in up to 10% of patients taking certain medications.
In Europe, the prevalence of drug-induced folate deficiency anaemia is also significant, with studies indicating that up to 5% of patients taking folate-interfering medications may develop this condition. The use of medications such as methotrexate, trimethoprim-sulfamethoxazole, and phenytoin has been associated with an increased risk of developing folate deficiency anaemia in European populations. Healthcare providers in Europe are advised to monitor patients taking these medications closely for signs of folate deficiency anaemia.
In Asia, drug-induced folate deficiency anaemia is a recognized clinical problem, particularly among populations with high rates of certain chronic diseases requiring treatment with medications that interfere with folate metabolism. The prevalence of this condition in Asia is similar to that seen in the United States and Europe, with up to 10% of patients taking folate-interfering medications experiencing folate deficiency anaemia. Healthcare providers in Asia should be vigilant in monitoring patients taking these medications for signs of folate deficiency anaemia and consider appropriate interventions to prevent or manage this condition.
In Africa, drug-induced folate deficiency anaemia is also a significant concern, particularly in regions where certain medications known to interfere with folate absorption or metabolism are commonly prescribed. The prevalence of this condition in Africa is not well documented, but studies suggest that the risk of developing folate deficiency anaemia due to drug therapy is similar to that seen in other regions worldwide. Healthcare providers in Africa should be aware of the potential for drug-induced folate deficiency anaemia in patients taking medications that interfere with folate metabolism and should take appropriate steps to prevent or manage this condition.
😷 Prevention
To prevent drug-induced folate deficiency anemia, individuals should be cautious when taking medications known to affect folate levels. It is important to consult with healthcare providers before starting or changing any medications, especially if there is a known risk of folate deficiency. Monitoring folate levels through blood tests can also help to detect and prevent potential deficiencies before they lead to anemia.
Certain drugs, such as antiepileptic medications and methotrexate, are known to interfere with folate metabolism and absorption, leading to deficiency over time. Healthcare providers should carefully evaluate the risks and benefits of these medications, taking into consideration the individual’s folate status and potential need for supplementation. In some cases, alternative medications with lower risk of folate deficiency may be considered to prevent anemia.
In addition to medication management, individuals can prevent drug-induced folate deficiency anemia through dietary interventions. Consuming a diet rich in folate-rich foods, such as leafy green vegetables, legumes, and fortified grains, can help to maintain adequate folate levels and reduce the risk of deficiency. Supplementing with folic acid, the synthetic form of folate, may also be recommended for individuals at high risk of drug-induced folate deficiency anemia, under the guidance of a healthcare provider.
🦠 Similar Diseases
One disease similar to 3A02.4 (Drug-induced folate deficiency anaemia) is megaloblastic anemia, which can also result from a deficiency in folate. Megaloblastic anemia is characterized by the presence of megaloblasts in the bone marrow, large red blood cells that are unable to divide properly, leading to anemia. Common symptoms of megaloblastic anemia include fatigue, weakness, and shortness of breath.
Another related disease is pernicious anemia, which is caused by a lack of intrinsic factor necessary for the absorption of vitamin B12. Without adequate levels of vitamin B12, the body is unable to produce enough red blood cells, leading to anemia. Symptoms of pernicious anemia may include weakness, pale skin, and neurological problems such as numbness or tingling in the hands and feet. Treatment typically involves vitamin B12 injections to restore levels in the body.
A third disease comparable to drug-induced folate deficiency anemia is aplastic anemia, a rare condition in which the bone marrow fails to produce enough blood cells. Aplastic anemia can be caused by medications, radiation, or exposure to toxic chemicals. Symptoms of aplastic anemia may include fatigue, frequent infections, and abnormal bleeding. Treatment options for aplastic anemia include blood transfusions, medications to stimulate blood cell production, and bone marrow transplantation in severe cases.
