ICD-11 code 3A61.1 refers to chronic acquired pure red cell aplasia, a rare disorder characterized by the body’s inability to produce enough red blood cells. This condition typically results in severe anemia, as the red blood cells are responsible for carrying oxygen to the body’s tissues.
Chronic acquired pure red cell aplasia is considered an autoimmune disorder, meaning the body’s immune system mistakenly attacks and destroys its own red blood cells. This disruption in the body’s normal red blood cell production cycle can lead to symptoms such as fatigue, weakness, and rapid heartbeat.
Treatment for chronic acquired pure red cell aplasia often involves medications to suppress the immune system and stimulate red blood cell production. In some cases, blood transfusions may be necessary to alleviate severe anemia. It is important for individuals with this condition to work closely with healthcare providers to manage symptoms and prevent complications.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to the ICD-11 code 3A61.1, which represents Chronic acquired pure red cell aplasia, is 206975004. SNOMED CT is a comprehensive clinical terminology that provides a common language for electronic health records and enables interoperability between different healthcare systems. This specific code accurately captures the diagnosis of a patient suffering from a chronic and acquired condition where the bone marrow does not produce enough red blood cells, leading to severe anemia. The SNOMED CT code 206975004 ensures that healthcare professionals can quickly and accurately communicate this specific diagnosis and treatment plan for patients with Chronic acquired pure red cell aplasia.
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 3A61.1, also known as chronic acquired pure red cell aplasia, may vary depending on the severity of the condition and the underlying cause. One common symptom of this disorder is fatigue, which can be attributed to the reduced number of red blood cells in the body. Patients with chronic acquired pure red cell aplasia may also experience weakness, dizziness, and shortness of breath during physical exertion.
In addition to fatigue and weakness, individuals with chronic acquired pure red cell aplasia may exhibit pallor, a condition in which the skin appears unusually pale. This is a direct result of the decreased number of red blood cells, which are responsible for carrying oxygen throughout the body. Pallor may be particularly noticeable in the face, lips, and nail beds.
Another symptom of 3A61.1 is an increased heart rate or palpitations, which can occur as the body tries to compensate for the reduced oxygen-carrying capacity of the blood. Patients with chronic acquired pure red cell aplasia may also experience chest pain, particularly during physical activity or when the heart is working harder to pump oxygen-deprived blood. It is important for individuals experiencing these symptoms to seek medical attention promptly to determine the underlying cause and receive appropriate treatment.
🩺 Diagnosis
Diagnosis of 3A61.1 (Chronic acquired pure red cell aplasia) involves a thorough evaluation of the patient’s medical history, physical examination, and laboratory tests. The initial step in diagnosis typically involves a complete blood count (CBC) to assess red blood cell levels, hemoglobin, and hematocrit. A low red blood cell count combined with low hemoglobin and hematocrit levels may indicate pure red cell aplasia.
Further diagnostic tests may include a reticulocyte count to determine the production of new red blood cells by the bone marrow. In cases of chronic acquired pure red cell aplasia, the reticulocyte count is often significantly low, indicating a failure of the bone marrow to produce red blood cells. Additional tests such as a bone marrow biopsy may be performed to evaluate the morphology and function of the bone marrow cells, providing further insight into the underlying cause of the condition.
In some cases, autoimmune testing may be conducted to assess the presence of antibodies that target and destroy red blood cells. Testing for underlying conditions such as viral infections, autoimmune disorders, or medication-induced pure red cell aplasia may also be recommended to identify potential triggers for the condition. A comprehensive diagnostic approach is essential to accurately diagnose and differentiate chronic acquired pure red cell aplasia from other causes of anemia.
💊 Treatment & Recovery
Treatment for 3A61.1, chronic acquired pure red cell aplasia, typically involves immunosuppressive therapy to alleviate the autoimmune response that is attacking the red blood cells. This therapy may include medications such as corticosteroids, cyclosporine, or rituximab to help suppress the immune system and allow the bone marrow to produce red blood cells normally. In some cases, blood transfusions may also be necessary to provide immediate relief from severe anemia.
In more severe cases where immunosuppressive therapy is ineffective, other treatment options may be considered. These may include invasive procedures such as plasmapheresis to remove antibodies from the blood or splenectomy to remove the spleen, which is a major site of red blood cell destruction. Ultimately, the choice of treatment will depend on the severity of the condition and the response to initial therapy.
Recovery from chronic acquired pure red cell aplasia can vary depending on the individual’s response to treatment and the underlying cause of the condition. Some patients may experience a complete recovery with appropriate therapy, while others may require long-term management to maintain stable red blood cell levels. Regular monitoring of blood counts and immunosuppressive therapy may be necessary to prevent relapses and ensure optimal outcomes for patients with this condition.
🌎 Prevalence & Risk
In the United States, the prevalence of 3A61.1, also known as chronic acquired pure red cell aplasia, is difficult to determine precisely due to lack of comprehensive data. The condition is considered rare, affecting an estimated 1 to 2 individuals per million people annually.
In Europe, the prevalence of chronic acquired pure red cell aplasia, specifically 3A61.1, is similarly low. The condition is regarded as uncommon, with an estimated incidence rate of less than 1 per million individuals per year.
In Asia, the prevalence of 3A61.1, or chronic acquired pure red cell aplasia, mirrors that of other regions, with the condition being rare. Limited data exist to provide a definitive estimate of its occurrence, but it is generally considered to affect fewer than 1 per million people annually.
