ICD-11 code 1B94.0 refers to ulceroglandular tularaemia, a specific type of tularaemia caused by the bacterium Francisella tularensis. This disease is characterized by the development of skin ulcers at the site of infection, usually on the hands or arms, along with swollen and tender lymph nodes in the affected area. Ulceroglandular tularaemia is one of several forms of tularaemia, a rare infectious disease that primarily affects animals like rabbits and rodents but can be transmitted to humans through insect bites or exposure to contaminated water or soil.
Symptoms of ulceroglandular tularaemia can include fever, chills, headache, muscle aches, and fatigue, in addition to the distinctive skin ulcers and swollen lymph nodes. Diagnosis of this condition typically involves a physical examination, blood tests, and possibly a biopsy of the ulcer or lymph nodes to confirm the presence of F. tularensis bacteria. Treatment for ulceroglandular tularaemia usually involves a course of antibiotics, such as streptomycin or gentamicin, to eliminate the infection and prevent complications like pneumonia or systemic spread of the bacteria.
The prognosis for patients with ulceroglandular tularaemia is generally good, especially if the infection is promptly diagnosed and treated. Most individuals recover fully with appropriate antibiotic therapy and supportive care, although some may experience lingering symptoms or complications. Preventative measures like avoiding contact with sick or dead animals, wearing insect repellent, and practicing good hygiene can help reduce the risk of contracting tularaemia and other zoonotic diseases.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to ICD-11 code 1B94.0 (Ulceroglandular tularaemia) is 417893002. This code specifically refers to the diagnosis of ulceroglandular tularemia, a rare but serious bacterial infection caused by Francisella tularensis. The use of SNOMED CT allows for standardized communication and coding of medical information across healthcare systems, facilitating accurate and efficient data exchange between healthcare providers. Utilizing SNOMED CT codes ensures that medical records are accurately classified and easily accessible for healthcare professionals, promoting better coordination of care and improved patient outcomes. By aligning with international coding standards like SNOMED CT, healthcare organizations can enhance interoperability and data exchange, ultimately leading to better clinical decision-making and patient care management.
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 1B94.0 (Ulceroglandular tularaemia) typically present with a 1-14 day incubation period following exposure to the bacterium Francisella tularensis. Patients may experience sudden onset of fever, chills, headache, muscle aches, joint pain, and fatigue. Additionally, an ulcer at the site of infection, commonly on the skin or mucous membranes, may develop.
In ulceroglandular tularaemia, regional lymph nodes near the site of the ulcer become enlarged and tender. Patients may also experience anorexia, nausea, vomiting, and other gastrointestinal symptoms. In severe cases, complications such as pneumonia, sepsis, meningitis, or osteomyelitis may occur, particularly if the infection spreads beyond the initial site.
Prompt diagnosis and treatment of ulceroglandular tularaemia are essential to prevent potentially serious complications. Healthcare providers should consider tularaemia in patients with compatible symptoms, especially if they have a history of exposure to contaminated water or wildlife. Laboratory tests, such as serologic testing or culture of the bacteria, can confirm the diagnosis of 1B94.0 (Ulceroglandular tularaemia).
🩺 Diagnosis
Diagnosis of 1B94.0 (Ulceroglandular tularaemia) typically involves a combination of clinical evaluation, laboratory tests, and imaging studies. A thorough physical examination is performed to assess the presence of characteristic symptoms such as skin ulcers and enlarged lymph nodes.
Laboratory tests may include blood tests to detect antibodies against the bacterium Francisella tularensis, the causative agent of tularaemia. Serologic tests such as the microagglutination test (MAT) or enzyme-linked immunosorbent assay (ELISA) are commonly used for this purpose.
In some cases, samples of affected tissue, such as skin biopsy or lymph node aspiration, may be collected for further analysis. These samples can be cultured to confirm the presence of F. tularensis or subjected to polymerase chain reaction (PCR) testing for genetic material from the bacterium.
Imaging studies such as ultrasound or computed tomography (CT) scans may be used to evaluate the extent of involvement of organs or tissues and to detect any complications of ulceroglandular tularaemia. These tests can help assess the severity of the infection and guide treatment decisions.
💊 Treatment & Recovery
Treatment for ulceroglandular tularaemia, caused by the bacterium Francisella tularensis, typically involves the use of antibiotics. The most commonly prescribed antibiotics for this infection include streptomycin, gentamicin, and doxycycline. Treatment duration may vary depending on the severity of the infection and the individual’s response to the medication.
In some cases, patients may require hospitalization for intravenous antibiotic therapy if they are unable to take oral medications or if the infection is severe. Supportive care, including rest, hydration, and pain management, may also be provided to help alleviate symptoms and promote recovery.
It is important for individuals with ulceroglandular tularaemia to complete the full course of antibiotics as prescribed by their healthcare provider, even if symptoms improve before the medication is finished. Failure to complete the treatment regimen could result in a relapse of the infection or the development of antibiotic resistance, making future infections more difficult to treat.
🌎 Prevalence & Risk
In the United States, ulceroglandular tularemia caused by the bacteria Francisella tularensis is a rare disease. Although cases have been reported in various states, including Arkansas, Missouri, Colorado, and South Dakota, the exact prevalence is difficult to determine due to underreporting and misdiagnosis. The disease is typically found in rural areas where the bacteria are present in wildlife populations, such as rabbits and rodents.
In Europe, ulceroglandular tularemia is more commonly reported in countries such as Sweden, Finland, and Norway. The prevalence of the disease varies by region, with higher rates seen in areas with a higher population of wildlife reservoirs for F. tularensis. Cases have been linked to activities such as hunting, farming, and insect bites. Surveillance systems in European countries have improved detection and reporting of tularemia cases, leading to a better understanding of the prevalence of the disease in the region.
In Asia, ulceroglandular tularemia is a rare disease with sporadic cases reported in countries such as Japan, China, and Russia. The prevalence of the disease in Asia is believed to be low compared to other regions, but due to limited surveillance systems and diagnostic capabilities, the true burden of tularemia is likely underestimated. Cases in Asia are often associated with outdoor activities in rural areas where the bacteria are present in wildlife populations. International collaboration and sharing of information on tularemia cases are important for monitoring and controlling the disease in Asia.
In Australia, ulceroglandular tularemia is a rare disease with only a few cases reported in the past. The prevalence of the disease in Australia is believed to be low, with sporadic cases linked to exposure to infected animals or contaminated environments. Due to the limited number of cases and the remote nature of some affected regions, the true burden of tularemia in Australia is difficult to determine. Public health efforts to raise awareness among healthcare providers and the public are important for early detection and prompt treatment of ulceroglandular tularemia in Australia.
😷 Prevention
To prevent 1B94.0 (Ulceroglandular tularaemia), it is important to understand the transmission of the disease and take appropriate precautions. Tularaemia is typically spread through the bite of infected ticks or deer flies, contact with contaminated soil or water, or handling of infected animals. Therefore, individuals in high-risk areas should take measures to avoid contact with potentially infected vectors or animals.
One key method of prevention is the use of insect repellent containing DEET when in areas where ticks or deer flies are prevalent. Additionally, wearing long-sleeved shirts and pants can help prevent insect bites and reduce the risk of tularaemia transmission. It is also important to thoroughly inspect your body and clothing for ticks after spending time outdoors, as prompt removal of ticks can prevent infection.
When handling potentially infected animals or carcasses, individuals should wear gloves and other protective gear to prevent direct contact with infected tissues or fluids. Proper hygiene practices, such as washing hands thoroughly after handling animals or potentially contaminated materials, are also crucial in preventing the spread of tularaemia. By taking these precautions, individuals can significantly reduce their risk of contracting 1B94.0 (Ulceroglandular tularaemia).
