ICD-11 code 1C11.0 refers to Carrion disease, a bacterial infection caused by Bartonella bacilliformis. This disease is primarily found in South America, particularly in mountainous regions of Peru, Ecuador, and Colombia. It is transmitted to humans through the bite of sand flies, which are the primary vectors for this infection.
Carrion disease is characterized by two distinct phases – the acute phase and the chronic phase. The acute phase is marked by symptoms such as fever, anemia, and enlarged lymph nodes, while the chronic phase is associated with skin lesions known as verruga peruana. If left untreated, Carrion disease can lead to severe complications, such as heart involvement and a potentially fatal condition known as Oroya fever.
Diagnosis of Carrion disease typically involves a combination of clinical symptoms, blood tests, and microscopic examination of blood smears. Treatment usually consists of antibiotics, such as ciprofloxacin or azithromycin, which can effectively clear the bacteria from the bloodstream. Early detection and prompt treatment are crucial in preventing the progression of Carrion disease to its more severe forms.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to ICD-11 code 1C11.0 is 46873009. Carrion disease, also known as Oroya fever, is a bacterial infection caused by Bartonella bacilliformis. This disease is transmitted through the bite of infected sand flies, primarily found in the Andes Mountains of South America. Symptoms of Carrion disease can include fever, anemia, and the formation of skin lesions called verruga peruana. Proper diagnosis and treatment of this illness are essential in preventing severe complications, such as severe anemia or even death in some cases. By utilizing the SNOMED CT code 46873009, healthcare professionals can accurately document and track cases of Carrion disease within electronic health records, facilitating effective patient care and research efforts in the field of infectious diseases.
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
Carrion disease, also known as Oroya fever and verruga peruana, is a bacterial infection caused by the Bartonella bacilliformis bacterium. The disease is primarily found in certain regions of South America with high altitudes, such as Peru, Ecuador, and Colombia. The symptoms of Carrion disease can present in two distinct phases: the acute phase and the chronic phase.
During the acute phase of Carrion disease, patients typically experience symptoms such as fever, headache, malaise, muscle aches, and anemia. The fever can be persistent and may be accompanied by chills and sweating. Patients may also develop hepatosplenomegaly, which is an enlargement of the liver and spleen.
As the disease progresses into the chronic phase, patients may develop skin lesions called verrugas, which are small, reddish-purple nodules that can ulcerate and bleed. These lesions can be found all over the body, most commonly on the face, limbs, and trunk. In severe cases, patients may experience complications such as endocarditis, which is an inflammation of the heart’s inner lining, leading to potentially life-threatening consequences. Early diagnosis and treatment are crucial in preventing the complications associated with Carrion disease.
🩺 Diagnosis
Diagnosis of Carrion disease, also known as Oroya fever, typically involves a combination of clinical presentation, laboratory tests, and epidemiological history. The disease primarily affects people in endemic areas such as the Andes mountains of South America. Symptoms can range from acute hemolytic anemia to chronic Bartonellosis.
In an acute phase, the diagnosis of Carrion disease can be challenging due to non-specific symptoms that can mimic other febrile illnesses. Laboratory tests such as blood smears, blood cultures, and serological tests are commonly used to confirm the presence of Bartonella bacilliformis, the bacterium responsible for Carrion disease. Serological tests may show high titers of antibodies against B. bacilliformis.
In the chronic phase of Carrion disease, diagnosis is often based on clinical symptoms such as benign cutaneous lesions known as verrugae peruanae and systemic involvement such as bone marrow suppression. Biopsy of skin lesions or bone marrow may help confirm the presence of B. bacilliformis. Molecular techniques such as polymerase chain reaction (PCR) can also be used to detect the bacterium in clinical samples. Epidemiological history of the patient’s residence or travel to endemic areas is crucial in diagnosing Carrion disease.
💊 Treatment & Recovery
Treatment for Carrion disease, caused by Bartonella bacilliformis, typically involves the use of antibiotics such as ciprofloxacin, doxycycline, or azithromycin. These medications are effective in treating the infection by targeting the bacteria responsible for the disease. In severe cases, patients may require hospitalization for intravenous antibiotics and supportive care such as fluids and pain management.
Early diagnosis and prompt treatment are crucial in the management of Carrion disease to prevent serious complications and reduce the risk of mortality. Patients who are suspected or confirmed to have the disease should start antibiotics immediately to halt the progression of the infection. Close monitoring of symptoms and response to treatment is essential to ensure successful recovery and prevent relapse of the disease.
In addition to antibiotic therapy, supportive care plays a critical role in the recovery of patients with Carrion disease. This may include management of dehydration, anemia, and other complications that may arise during the course of the illness. Patients may also benefit from rest, adequate nutrition, and close follow-up with healthcare providers to monitor their progress and ensure a complete recovery.
🌎 Prevalence & Risk
In the United States, Carrion disease is considered to be rare, with only a few cases reported each year. The disease is mostly seen in individuals who have traveled to regions where the causative agent, Bartonella bacilliformis, is endemic, such as parts of South America. Due to the limited number of cases and the rare occurrence of the disease outside of endemic areas, Carrion disease is not a major public health concern in the United States.
In Europe, Carrion disease is virtually non-existent, and cases are extremely rare. The disease is not endemic to European countries, and the risk of acquiring the infection is low for individuals residing in or visiting these regions. However, sporadic cases may occur in travelers returning from areas where Bartonella bacilliformis is prevalent, but these cases are uncommon and isolated.
In Asia, Carrion disease is more prevalent compared to Europe and the United States, with endemic areas in countries such as Peru, Ecuador, and Colombia. The disease is primarily found in mountainous regions with temperate climates, and individuals who live in or travel to these areas are at risk of contracting the infection. While the prevalence of Carrion disease in Asia is higher than in other regions, the disease is still considered relatively uncommon overall.
In Africa, Carrion disease is rare, with only a limited number of cases reported in certain regions. The disease is not endemic to most African countries, and the risk of acquiring the infection is low for individuals residing in these areas. However, cases may occur in travelers who have visited endemic regions in South America and subsequently developed symptoms upon returning to Africa.
😷 Prevention
There are various measures that can be taken to prevent 1C11.0 (Carrion disease) in individuals living in endemic areas. One key preventive method is to avoid contact with infected individuals or animals, such as those with Oroya fever or those harboring the Bartonella bacilliformis bacterium. In addition, individuals should take precautions to avoid insect bites by using insect repellent, wearing long sleeves and pants, and sleeping under insecticide-treated bed nets.
Another crucial preventive measure is to improve hygiene practices in endemic areas where Carrion disease is prevalent. This includes ensuring proper sanitation facilities and promoting regular handwashing with soap and water to reduce the risk of transmission of the bacterium. Furthermore, individuals should be educated on the importance of avoiding unsanitary conditions and maintaining a clean living environment to prevent the spread of 1C11.0.
Lastly, individuals living in endemic areas should seek prompt medical attention if they experience symptoms suggestive of Carrion disease, such as fever, body aches, and skin lesions. Early diagnosis and treatment are essential in preventing the progression of the disease to the more severe form, known as verruga peruana. Physicians in endemic areas should be knowledgeable about the disease and its presentation to ensure timely intervention and reduce the risk of complications in affected individuals.
