ICD-11 code 3A61.Y refers to “Other specified acquired pure red cell aplasia.” This code is used to classify a specific type of acquired anemia characterized by a decrease in red blood cells due to a lack of erythropoiesis or production of red blood cells in the bone marrow.
Acquired pure red cell aplasia is a rare disorder in which the bone marrow fails to produce an adequate number of red blood cells, leading to anemia. The specific cause of this condition is often unknown, but it can be associated with autoimmune diseases, infections, medications, or exposure to toxins.
The ‘Y’ in the code 3A61.Y indicates that the specific cause or etiology of the acquired pure red cell aplasia is not further specified in the classification. This allows for flexibility in coding when the exact underlying reason for the condition is not definitively known or documented in the medical record.

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.Y (Other specified acquired pure red cell aplasia) can vary depending on the severity of the condition. One common symptom is fatigue, which can range from mild to severe and may be accompanied by weakness. Patients with pure red cell aplasia may also experience dizziness or lightheadedness, especially when standing up quickly.
Another symptom of 3A61.Y is paleness, often noticeable in the skin, lips, and the mucous membranes of the mouth and eyes. This paleness is due to a decrease in the number of red blood cells, which carry oxygen to the body’s tissues. Patients may also develop shortness of breath, particularly during physical activity, as a result of reduced oxygen delivery to the muscles.
In some cases, patients with 3A61.Y may exhibit symptoms of anemia, such as rapid heartbeat, chest pain, and headaches. Anemia occurs when the body is unable to produce enough red blood cells to meet its oxygen needs. Additionally, individuals with pure red cell aplasia may experience increased susceptibility to infections due to a weakened immune system resulting from the lack of red blood cells.
🩺 Diagnosis
Diagnosis of 3A61.Y (Other specified acquired pure red cell aplasia) involves a thorough evaluation of the patient’s medical history, physical examination, and laboratory tests. The symptoms of red cell aplasia may include fatigue, weakness, pale skin, and shortness of breath. An important aspect of the diagnostic process is differentiating acquired red cell aplasia from other causes of anemia, such as nutritional deficiencies or chronic diseases.
Laboratory tests play a crucial role in confirming the diagnosis of 3A61.Y. Blood tests, such as complete blood count (CBC), reticulocyte count, and peripheral blood smear, are commonly used to assess the quantity and quality of red blood cells. In patients with red cell aplasia, the CBC may reveal low levels of red blood cells, hemoglobin, and hematocrit. A reticulocyte count, which measures the number of immature red blood cells, can help determine the bone marrow’s ability to produce new red blood cells.
In some cases, additional tests may be necessary to identify the underlying cause of red cell aplasia. Bone marrow biopsy and genetic testing may be performed to rule out conditions such as autoimmune disorders, viral infections, or certain medications that can lead to the development of red cell aplasia. Imaging studies, such as ultrasound or magnetic resonance imaging (MRI), may also be ordered to assess the structure and function of the bone marrow. Overall, a comprehensive approach to diagnosis is essential for proper management and treatment of 3A61.Y (Other specified acquired pure red cell aplasia).
💊 Treatment & Recovery
Treatment for 3A61.Y, or Other specified acquired pure red cell aplasia, typically involves a combination of medications and supportive care. One common approach is the use of immunosuppressive drugs to suppress the immune response that is attacking the red blood cells. These medications can help to alleviate symptoms and allow the bone marrow to produce red blood cells again.
In some cases, patients may also require blood transfusions to help maintain adequate levels of red blood cells in the body. This can provide temporary relief while other treatments take effect. However, frequent blood transfusions can come with risks, such as iron overload and transfusion reactions, so they are typically used as a short-term solution.
In more severe cases of 3A61.Y, treatments such as splenectomy or stem cell transplant may be considered. A splenectomy involves removing the spleen, which is often the site of immune system attacks on red blood cells. This can help to improve red blood cell production. Stem cell transplants involve replacing the bone marrow with healthy stem cells to stimulate new red blood cell production. These treatments are typically reserved for cases that do not respond to other therapies.
🌎 Prevalence & Risk
In the United States, the prevalence of 3A61.Y (Other specified acquired pure red cell aplasia) is relatively low compared to other types of acquired pure red cell aplasia. This specific category of acquired pure red cell aplasia is not as commonly reported or diagnosed in clinical practice, which contributes to its lower prevalence in the United States.
In Europe, the prevalence of 3A61.Y is also relatively low, similar to the trends seen in the United States. While acquired pure red cell aplasia as a broader category may be more prevalent in certain regions of Europe, the specific classification of 3A61.Y as “Other specified acquired pure red cell aplasia” remains less common compared to other subtypes in the region.
In Asia, the prevalence of 3A61.Y is not well documented or widely reported, making it difficult to assess the exact frequency of this specific subtype of acquired pure red cell aplasia in the region. However, based on available data, it is likely that the prevalence of 3A61.Y in Asia is consistent with the lower rates observed in the United States and Europe.
In Australia, the prevalence of 3A61.Y (Other specified acquired pure red cell aplasia) is similarly low compared to other types of acquired pure red cell aplasia. The classification of 3A61.Y as a specific subtype of acquired pure red cell aplasia is not frequently encountered in clinical practice, contributing to its lower prevalence in Australia. Additional research and data collection may help to better understand the prevalence of 3A61.Y in these regions and improve the overall knowledge of this subtype of acquired pure red cell aplasia worldwide.
😷 Prevention
It is crucial to address potential underlying causes of 3A61.Y, such as infections, autoimmune disorders, or exposure to toxic substances. Preventative measures may involve maintaining a healthy lifestyle, avoiding harmful environments, and seeking prompt medical attention for any signs of infection or immunological abnormalities. Additionally, individuals with a family history of red cell aplasia should be vigilant in monitoring their health and seeking regular check-ups with a healthcare provider.
In cases where 3A61.Y is related to autoimmune disorders, it may be beneficial to focus on managing the underlying condition through medication, therapy, and lifestyle modifications. Physicians may recommend regular blood tests to monitor for any signs of red cell aplasia and adjust treatment accordingly. Engaging in stress-reducing activities, maintaining a balanced diet, and adhering to prescribed medications can help minimize the risk of developing acquired pure red cell aplasia in individuals with autoimmune disorders.
Furthermore, individuals at risk for exposure to toxic substances should take precautions to avoid harmful chemicals or pollutants. This may involve using protective equipment in hazardous work environments, following safety guidelines for handling toxic materials, and seeking medical advice if exposed to potentially harmful substances. Education on the risks associated with certain chemicals and regular health screenings can help prevent the development of red cell aplasia in individuals with occupational or environmental exposure to toxins.
