ICD-11 code 3A61.Z refers to acquired pure red cell aplasia, unspecified. This condition is characterized by the body’s inability to produce an adequate number of red blood cells due to the destruction of red cell precursors in the bone marrow. Patients with this condition often experience symptoms such as fatigue, weakness, and pallor due to the decreased oxygen-carrying capacity of the blood.
The underlying cause of acquired pure red cell aplasia is often unknown, but it can be linked to autoimmune disorders, infections, medications, or exposure to toxins. The diagnosis of this condition is usually confirmed through blood tests and bone marrow biopsies. Treatment options typically include blood transfusions, immunosuppressive therapy, and addressing the underlying cause if possible. Early detection and management of acquired pure red cell aplasia are crucial for preventing complications such as severe anemia and organ damage.

#️⃣ Coding Considerations
In the realm of medical coding, the equivalent SNOMED CT code for the ICD-11 code 3A61.Z (Acquired pure red cell aplasia, unspecified) is 50410009. This SNOMED code specifically represents a diagnosis of acquired pure red cell aplasia, which is characterized by a severe deficiency of red blood cells due to the failure of the bone marrow to produce them. This condition is considered a rare autoimmune disorder in which the immune system attacks and destroys red blood cell precursors, leading to anemia and other complications. The SNOMED CT code 50410009 allows healthcare professionals to accurately document and track cases of acquired pure red cell aplasia for proper treatment and monitoring of patients with this condition.
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.Z, or Acquired pure red cell aplasia, unspecified, may vary depending on the severity of the condition. Patients with this disorder may experience symptoms suggestive of anemia, such as fatigue, weakness, and pallor. In some cases, individuals may also exhibit symptoms of heart palpitations, shortness of breath, and dizziness.
As the disease progresses, patients with 3A61.Z may develop additional symptoms related to the lack of red blood cells, including jaundice, a condition characterized by yellowing of the skin and eyes. In severe cases of pure red cell aplasia, individuals may also experience symptoms such as rapid heartbeat, chest pain, and difficulty concentrating. These symptoms may be indicative of complications associated with the disorder, such as heart failure or stroke.
Patients with 3A61.Z may also present with symptoms related to immune dysfunction, as the condition is often associated with an abnormal immune response that targets red blood cells. These symptoms may include frequent infections, swollen lymph nodes, and easy bruising or bleeding. Additionally, individuals with pure red cell aplasia may have an increased risk of developing other autoimmune disorders, which can further complicate the clinical presentation of the condition.
🩺 Diagnosis
Diagnosis of Acquired Pure Red Cell Aplasia (APRCA), unspecified, can be challenging due to its rare and heterogeneous nature. Various diagnostic methods are utilized by healthcare professionals to identify and confirm the condition in affected individuals. These methods may include a thorough physical examination, detailed medical history review, and laboratory tests.
Laboratory tests play a crucial role in the diagnosis of APRCA, assisting in the evaluation of red blood cell counts, hemoglobin levels, and other blood parameters. Specific tests such as a reticulocyte count, erythropoietin levels, and bone marrow biopsy may be ordered to further investigate the underlying cause of pure red cell aplasia. These tests help to differentiate APRCA from other anemias and bone marrow disorders, leading to an accurate diagnosis.
In some cases, imaging studies such as ultrasound, computed tomography (CT) scans, or magnetic resonance imaging (MRI) may be recommended to visualize the bone marrow and assess its function. These imaging techniques provide additional information regarding the structure and composition of the bone marrow, aiding in the diagnosis and management of APRCA. Collaboration among healthcare professionals, including hematologists, oncologists, and pathologists, is essential in the comprehensive evaluation and diagnosis of Acquired Pure Red Cell Aplasia.
💊 Treatment & Recovery
Treatment for Acquired Pure Red Cell Aplasia, unspecified (3A61.Z) typically involves addressing the underlying cause of the condition, if known. In cases where an autoimmune disorder is the culprit, immunosuppressive therapy may be prescribed to help modulate the immune response and allow for the production of red blood cells to resume.
In some instances, blood transfusions may be necessary to manage severe anemia that results from a lack of red blood cells. This can provide temporary relief and improve symptoms, but it is not a long-term solution. Patients may need regular transfusions until their bone marrow is able to recover and produce enough red blood cells on its own.
For individuals with Acquired Pure Red Cell Aplasia, unspecified, who do not respond well to traditional treatments, more aggressive approaches such as stem cell transplantation or bone marrow transplants may be considered. These procedures aim to replace the faulty bone marrow with healthy cells that can produce red blood cells normally. However, these interventions carry significant risks and are typically reserved for severe or refractory cases.
🌎 Prevalence & Risk
In the United States, the prevalence of 3A61.Z (Acquired pure red cell aplasia, unspecified) is difficult to ascertain due to underdiagnosis and lack of a national registry for this rare condition. However, it is estimated that the incidence of acquired pure red cell aplasia in adults is between 2 and 5 cases per million population per year.
In Europe, the prevalence of 3A61.Z is similarly challenging to determine accurately. Various studies have reported varying prevalence rates in different European countries, with estimates ranging from 1 to 6 cases per million population per year. The condition is considered to be rare but may be underdiagnosed in many cases.
In Asia, the prevalence of acquired pure red cell aplasia is also scarce in the literature. Limited data on the prevalence of this condition in Asian countries make it challenging to provide precise estimates. The lack of awareness and access to healthcare services may contribute to underdiagnosis and underreporting of cases in this region.
In Africa, there is a notable paucity of data on the prevalence of 3A61.Z. Limited research and resources dedicated to rare blood disorders in African countries contribute to the lack of reliable statistics on acquired pure red cell aplasia. The true prevalence in Africa remains largely unknown, highlighting the need for further research and awareness in this area.
😷 Prevention
Preventing 3A61.Z, or Acquired pure red cell aplasia, unspecified, involves managing underlying conditions that may trigger the development of the disorder. One common cause of pure red cell aplasia is exposure to certain medications, such as antiretroviral drugs or antiepileptic agents. To prevent medication-induced pure red cell aplasia, healthcare providers should carefully monitor patients taking these medications for signs of red cell destruction and promptly discontinue any suspect drugs.
In cases where pure red cell aplasia is linked to an autoimmune disorder, preventing the condition involves controlling the autoimmune response within the body. Immunosuppressive therapy may be necessary to dampen the immune system’s attack on red blood cells. Monitoring for signs of worsening anemia and promptly adjusting treatment can help prevent the progression of pure red cell aplasia in these cases.
Patients with chronic kidney disease are at increased risk of developing pure red cell aplasia due to impaired production of erythropoietin, a hormone necessary for red blood cell production. Preventing pure red cell aplasia in these individuals involves closely monitoring and managing their kidney function. Ensuring adequate nutrition, avoiding nephrotoxic medications, and initiating erythropoietin replacement therapy as needed can help prevent the development of pure red cell aplasia secondary to chronic kidney disease.
