ICD-11 code 3A01.30 refers to the medical condition known as pernicious anemia. This disorder is characterized by a lack of red blood cells due to the body’s inability to properly absorb vitamin B12. Pernicious anemia is often caused by an autoimmune reaction that targets cells in the stomach that produce intrinsic factor, a protein necessary for vitamin B12 absorption.
Patients with pernicious anemia may experience symptoms such as fatigue, weakness, shortness of breath, and pale or jaundiced skin. If left untreated, this condition can lead to more serious complications, including neurological problems and an increased risk of developing stomach cancer. Treatment usually involves regular injections of vitamin B12 to help alleviate symptoms and prevent further complications associated with the deficiency.

#️⃣ Coding Considerations
The equivalent SNOMED CT code for the ICD-11 code 3A01.30 for Pernicious anaemia is 388107006. This specific SNOMED CT code is used to identify the same condition as described by ICD-11. Pernicious anaemia is a type of anemia characterized by the body’s inability to absorb vitamin B12 from the digestive system due to a lack of intrinsic factor. This condition can lead to a range of symptoms such as fatigue, weakness, pale skin, shortness of breath, and neurological issues. By using the SNOMED CT code 388107006, healthcare professionals can accurately document and track cases of Pernicious anaemia in electronic health records, facilitating better communication and coordination of care among providers.
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
The symptoms of Pernicious anaemia (3A01.30) are varied and can manifest in a number of ways. Fatigue is one of the most common symptoms reported by individuals with this condition. This fatigue is often described as extreme and persistent, even with adequate rest.
Another common symptom of Pernicious anaemia is weakness, which can affect overall muscle strength and coordination. This weakness may present as difficulty with everyday activities such as walking, lifting objects, or climbing stairs. In severe cases, individuals may experience muscle atrophy.
Individuals with Pernicious anaemia may also experience neurological symptoms, including numbness or tingling in the hands and feet. This sensation is known as peripheral neuropathy and is caused by damage to the nerves. Other neurological symptoms may include difficulty with concentration, memory loss, and problems with balance and coordination.
🩺 Diagnosis
Diagnosis of pernicious anemia typically involves several methods to confirm the presence of the condition. Initially, a physical examination will be conducted by a healthcare provider, who will assess symptoms such as fatigue, weakness, and pale or yellow skin. A complete blood count (CBC) may be ordered to check for low levels of red blood cells and hemoglobin, which are common indicators of anemia.
Further diagnostic tests may include a blood smear, in which a sample of blood is examined under a microscope to assess the size, shape, and number of red blood cells. Additionally, a peripheral blood smear may be performed to look for characteristic large, oval-shaped red blood cells known as megaloblasts. This finding can suggest a deficiency of vitamin B12, which is essential for the production of red blood cells.
Another key diagnostic tool for pernicious anemia is the measurement of vitamin B12 levels in the blood. A deficiency of this vitamin is often at the root of the condition, as it impairs the body’s ability to produce healthy red blood cells. In some cases, intrinsic factor antibodies may also be tested to determine if the immune system is targeting the protein responsible for absorbing vitamin B12 in the digestive tract. These tests can help confirm a diagnosis of pernicious anemia and guide treatment decisions for the condition.
💊 Treatment & Recovery
Treatment for Pernicious Anemia typically involves lifelong vitamin B12 supplementation, as the condition stems from a lack of intrinsic factor in the stomach that prevents proper absorption of the vitamin. The most common method of administration is through B12 injections, which bypass the digestive system and deliver the vitamin directly into the bloodstream. In some cases, high oral doses of B12 may be effective for maintenance therapy once initial levels are replenished.
Regular monitoring of B12 levels through blood tests is essential to evaluate the effectiveness of treatment and adjust supplementation as needed. In severe cases, patients may require monthly injections initially to boost B12 levels quickly, followed by less frequent injections for maintenance. In some instances, oral B12 supplements may be sufficient for milder cases, but close monitoring and adjustment of dosage are still necessary to prevent deficiency.
In addition to B12 supplementation, treatment for Pernicious Anemia may also involve addressing any underlying conditions contributing to the deficiency, such as autoimmune disorders like autoimmune gastritis. Managing these conditions can help prevent further damage to the stomach lining and improve B12 absorption. Overall, the goal of treatment is to maintain adequate B12 levels in the body to alleviate symptoms and prevent complications associated with long-term B12 deficiency.
🌎 Prevalence & Risk
In the United States, prevalence of 3A01.30, also known as pernicious anaemia, is estimated to be between 0.1% and 0.8% of the general population. This condition is more common in individuals of Northern European descent, particularly those of Scandinavian or British Isles ancestry. Pernicious anaemia is more prevalent in older adults, with the average age of diagnosis being around 60 years old.
In Europe, prevalence of pernicious anaemia varies among countries, with higher rates reported in Northern European countries such as the United Kingdom and Sweden. In these regions, prevalence rates can reach up to 2% of the population, particularly in older adults. In Southern European countries, such as Spain and Italy, prevalence rates are lower, ranging from 0.5% to 1%.
In Asia, prevalence of pernicious anaemia is generally lower compared to Western countries, with reported rates ranging from 0.1% to 0.5% of the population. This condition is less common in Asian populations due to genetic differences in the susceptibility to developing pernicious anaemia. However, prevalence rates may vary among different Asian countries, with some regions experiencing slightly higher rates due to factors such as dietary deficiencies or genetic predisposition.
In Africa, prevalence of pernicious anaemia is relatively low compared to other regions, with reported rates ranging from 0.1% to 0.3% of the population. This condition is less common in African populations, possibly due to genetic factors that confer protection against autoimmune diseases such as pernicious anaemia. However, prevalence rates may vary among African countries, with some regions experiencing slightly higher rates due to factors such as dietary deficiencies or genetic predisposition.
😷 Prevention
To prevent Pernicious anaemia, also known as 3A01.30 in medical coding, several strategies can be employed to ensure proper functioning of the immune system and absorption of vitamin B12. One important step is to maintain a consistent and balanced diet rich in foods containing vitamin B12, such as meat, fish, dairy products, and fortified cereals.
Another crucial aspect of preventing Pernicious anaemia is to address any underlying conditions that may be causing deficiencies in vitamin B12 absorption. This may involve treating conditions such as chronic gastritis, celiac disease, or Crohn’s disease, which can affect the ability of the body to absorb vitamin B12 adequately. Proper management of these conditions can help prevent the development of Pernicious anaemia.
In addition to dietary and medical interventions, individuals at risk for Pernicious anaemia may also benefit from vitamin B12 supplements. These supplements can help maintain adequate levels of vitamin B12 in the body, even if absorption is impaired due to underlying conditions. Regular monitoring of vitamin B12 levels and adjusting supplement doses as needed can help prevent Pernicious anaemia in susceptible individuals.
🦠 Similar Diseases
One disease similar to 3A01.30 (Pernicious anaemia) is 3A01.00 (Vitamin B12 deficiency anemia) which also involves a lack of sufficient vitamin B12 in the body. This condition can lead to symptoms such as weakness, fatigue, numbness or tingling in the hands and feet, and difficulty walking. In severe cases, vitamin B12 deficiency anemia can cause neurological problems and even irreversible damage if left untreated.
Another disease related to 3A01.30 is 3A01.10 (Megablastic anemia) which is characterized by abnormally large red blood cells. This type of anemia can be caused by a deficiency in vitamin B12 or folic acid, both of which are necessary for the production of healthy red blood cells. Symptoms of megablastic anemia can include fatigue, weakness, pale skin, and shortness of breath.
3A01.20 (Gastric cancer) is another disease that can be associated with pernicious anemia. Pernicious anemia is often caused by an autoimmune reaction that damages the stomach lining, leading to a decrease in the production of intrinsic factor which is necessary for the absorption of vitamin B12. In some cases, this autoimmune reaction can also increase the risk of developing gastric cancer. Symptoms of gastric cancer can include abdominal pain, nausea, unintended weight loss, and difficulty swallowing.
Additionally, 3A01.40 (Atrophic gastritis) is a condition that involves inflammation of the stomach lining, resulting in a decrease in the production of stomach acid and intrinsic factor. Both of these substances are crucial for the absorption of vitamin B12. Atrophic gastritis can lead to pernicious anemia if left untreated, as the body is unable to properly absorb vitamin B12 from food. Symptoms of atrophic gastritis can include stomach pain, bloating, nausea, and a decreased appetite.
