ICD-11 code 3A21.2 corresponds to haemolytic uraemic syndrome, a rare but serious medical condition that involves the destruction of red blood cells and the impairment of kidney function. This syndrome typically occurs as a response to certain types of bacterial infections, particularly those caused by Shiga toxin-producing E. coli.
The hallmark symptoms of haemolytic uraemic syndrome include abdominal pain, diarrhea (often bloody), and decreased urine output. In severe cases, individuals with this condition may develop acute kidney failure, anemia, and clotting abnormalities. Prompt diagnosis and treatment are crucial in managing this potentially life-threatening syndrome.
Treatment of haemolytic uraemic syndrome usually involves supportive care, such as intravenous fluids and blood transfusions, to address complications like anemia and kidney damage. In some cases, patients may require dialysis or other interventions to maintain kidney function. Proper hydration and close monitoring of blood pressure are also essential in the management of this condition.

#️⃣ Coding Considerations
The equivalent SNOMED CT code for the ICD-11 code 3A21.2, which corresponds to Haemolytic Uraemic Syndrome, is 105770001. This specific SNOMED CT code is used to identify the condition in healthcare settings and facilitate standardized communication and data exchange among healthcare professionals. SNOMED CT codes are an important tool for ensuring accurate and consistent coding of diseases and conditions across different healthcare systems and organizations. Understanding the equivalent SNOMED CT code for a given ICD-11 code is crucial for proper coding and classification of medical conditions, ultimately leading to improved patient care and outcomes. Health information management professionals play a key role in ensuring that codes such as 105770001 are correctly assigned in electronic health records and other clinical documentation to support accurate diagnosis and treatment.
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 3A21.2, known as Haemolytic Uraemic Syndrome, typically manifest as abrupt-onset gastrointestinal issues such as stomach pain, diarrhea, and vomiting. These symptoms are often accompanied by the presence of blood in the stool, termed hematochezia. Patients may also experience fatigue, pale skin, and decreased urine output as the condition progresses.
In severe cases of Haemolytic Uraemic Syndrome, affected individuals may develop symptoms related to kidney damage, including decreased renal function and high blood pressure. This can lead to the accumulation of waste products in the blood, causing symptoms such as weakness, confusion, and fluid retention. Furthermore, individuals with the syndrome may also exhibit signs of anemia, such as shortness of breath, dizziness, and a rapid heartbeat.
In some instances, Haemolytic Uraemic Syndrome can lead to neurological complications, with patients experiencing seizures, altered consciousness, and stroke-like symptoms. These neurological manifestations may arise due to the presence of toxins released by the bacteria responsible for triggering the syndrome. It is crucial for individuals exhibiting any of these symptoms to seek immediate medical attention to prevent further complications and ensure prompt treatment.
🩺 Diagnosis
Diagnosis of 3A21.2 (Haemolytic uraemic syndrome) typically involves a thorough medical history review, physical examination, and laboratory tests. Patients may present with symptoms such as decreased urine output, fatigue, pale skin, and bruising.
Laboratory tests play a crucial role in diagnosing Haemolytic uraemic syndrome. Blood tests may reveal low red blood cell count, low platelet count, and evidence of hemolysis. Urine tests can show signs of kidney damage, such as protein or blood in the urine.
Imaging studies, such as ultrasound or CT scans, may be performed to assess the extent of kidney damage. These tests can help identify any abnormalities in the kidneys, such as swelling or changes in blood flow. Additionally, a kidney biopsy may be recommended in some cases to confirm the diagnosis of Haemolytic uraemic syndrome and determine the underlying cause.
💊 Treatment & Recovery
Treatment for 3A21.2, also known as Haemolytic Uraemic Syndrome (HUS), typically involves supportive care to manage symptoms and complications. This may include the administration of intravenous fluids to maintain hydration and electrolyte balance, as well as medications to control high blood pressure and blood coagulation.
In severe cases of HUS, such as those with kidney failure or central nervous system involvement, more aggressive treatments may be necessary. This can include kidney dialysis to help the kidneys filter waste and excess fluid from the blood, as well as plasma exchange or transfusions to replace damaged blood components.
Recovery from HUS can vary depending on the severity of the condition and the individual’s overall health. In mild cases, patients may recover fully within a few weeks with proper medical care and monitoring. However, in more severe cases, long-term complications such as kidney damage or neurological issues may persist, requiring ongoing treatment and management. Close follow-up with healthcare providers is essential to ensure the best possible outcome for those affected by HUS.
🌎 Prevalence & Risk
In the United States, the prevalence of 3A21.2, also known as Haemolytic uraemic syndrome, is estimated to be 2-7 cases per 100,000 individuals annually. This condition primarily affects children under the age of 5, with the highest incidence reported in those under 2 years old. The exact prevalence may vary depending on the geographical region and access to healthcare resources.
In Europe, the prevalence of 3A21.2 is reported to be slightly lower compared to the United States, ranging from 1-6 cases per 100,000 individuals per year. Similar to the US, children are most commonly affected by this syndrome in Europe, with a peak incidence in infants and young children. There may be differences in prevalence rates between Eastern and Western European countries due to variations in healthcare infrastructure and reporting practices.
In Asia, the prevalence of 3A21.2 varies widely across different countries and regions. Limited data is available on the exact prevalence in Asian populations, but studies have suggested a range of 0.5-3 cases per 100,000 individuals annually. Factors such as differences in genetic predisposition, dietary habits, and environmental exposures may contribute to variations in prevalence within Asia.
In Africa, the prevalence of 3A21.2 is believed to be higher compared to other regions due to factors such as poor sanitation, limited access to clean water, and higher burden of infectious diseases. However, accurate epidemiological data on the prevalence of Haemolytic uraemic syndrome in African countries is limited. Further research and data collection are needed to better understand the burden of this condition in Africa.
😷 Prevention
To prevent Haemolytic uraemic syndrome, it is crucial to focus on preventing the underlying conditions that can lead to this disorder. One key way to prevent this syndrome is by maintaining good hygiene practices, particularly in food preparation and handling. Ensuring that meat is cooked thoroughly and avoiding unpasteurized milk products can help reduce the risk of developing the infections that can lead to Haemolytic uraemic syndrome.
Another important factor in preventing Haemolytic uraemic syndrome is to promote a healthy immune system. This can be achieved through a balanced diet rich in fruits and vegetables, regular exercise, and adequate sleep. By strengthening the body’s immune response, individuals may be better equipped to fight off infections that could potentially trigger the development of Haemolytic uraemic syndrome.
In addition to these preventive measures, it is essential for individuals at higher risk for Haemolytic uraemic syndrome, such as young children and the elderly, to practice proper handwashing techniques and avoid contact with individuals who are ill. By taking these precautions, the spread of infections that can lead to Haemolytic uraemic syndrome may be minimized, reducing the likelihood of developing this serious condition.
