ICD-11 code 1F85 represents paragonimiasis, a type of parasitic infection caused by certain species of lung flukes belonging to the genus Paragonimus. These parasites primarily infect the lungs, causing symptoms such as cough, chest pain, and difficulty breathing. In severe cases, paragonimiasis can lead to complications such as pneumonia, pleurisy, and even death if left untreated.
Paragonimiasis is commonly transmitted to humans through the consumption of raw or undercooked crustaceans, such as crabs and freshwater crawfish, that harbor the infective larvae of the parasite. The larvae penetrate the intestinal wall, migrate through the body, and eventually settle in the lungs where they mature into adult flukes and lay eggs. These eggs are then coughed up and swallowed by the host, passing in the feces and potentially contaminating water sources to infect other hosts.
Diagnosis of paragonimiasis is often based on a combination of clinical symptoms, imaging studies such as chest X-rays or CT scans, and laboratory tests to detect the presence of parasite eggs in sputum or stool samples. Treatment typically involves the use of antiparasitic medications like praziquantel or triclabendazole to kill the parasites and alleviate symptoms. Patients may also require supportive care to manage complications and facilitate recovery from the infection.

#️⃣ Coding Considerations
Sometimes referred to as lung fluke disease, Paragonimiasis is a rare parasitic infection caused by the lung fluke Paragonimus. The equivalent SNOMED CT code for the ICD-11 code 1F85, which represents Paragonimiasis, is 23905005. This code specifically denotes an infection caused by Paragonimus species, including Paragonimus westermani, Paragonimus kellicotti, and others.
Paragonimiasis is typically acquired through the consumption of raw or undercooked freshwater crustaceans, which serve as intermediate hosts for the parasite. Upon ingestion, the Paragonimus larvae migrate to the lungs, where they develop into adult flukes and cause symptoms such as coughing, chest pain, and hemoptysis. However, diagnosis and treatment of Paragonimiasis can be challenging due to its rarity and the potential for misdiagnosis.
Therefore, accurate coding and documentation of cases of Paragonimiasis using the SNOMED CT code 23905005 is essential for proper identification, management, and surveillance of this parasitic disease.
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 Paragonimiasis (1F85) can vary depending on the stage of infection. In the early stages, individuals may experience coughing, chest pain, and difficulty breathing. Other common symptoms include fever, fatigue, and abdominal pain.
As the infection progresses, individuals with Paragonimiasis may develop a chronic cough, which can produce phlegm or blood. Some patients may also experience weight loss, decreased appetite, and wheezing. Additionally, individuals may exhibit symptoms of pneumonia, such as fever, chills, and sweating.
In more severe cases of Paragonimiasis, individuals may develop neurological symptoms, such as seizures or weakness in the limbs. Other potential complications include accumulation of fluid in the lungs, known as pleural effusion, and inflammation of the lining of the lungs, called pleurisy. Overall, prompt diagnosis and treatment of Paragonimiasis can help prevent the progression of symptoms and improve patient outcomes.
🩺 Diagnosis
Diagnosis of 1F85, also known as Paragonimiasis, can be challenging due to the nonspecific symptoms that may mimic other parasitic infections or respiratory diseases. Laboratory tests are essential for confirming the presence of Paragonimus spp. eggs in sputum, feces, or other body fluids. Microscopic examination of these samples can reveal characteristic operculated eggs with a thick shell and a single spine, aiding in the definitive diagnosis of paragonimiasis.
In addition to traditional microscopy techniques, serological tests are commonly used for diagnosing 1F85. Enzyme-linked immunosorbent assay (ELISA) and indirect hemagglutination tests can detect antibodies produced in response to Paragonimus spp. infection. Serological tests may be particularly useful in cases where parasite eggs are not detected in clinical samples or when a non-pulmonary form of paragonimiasis is suspected.
Imaging studies, such as chest X-rays or computed tomography (CT) scans, can help in the diagnosis of 1F85 by revealing characteristic findings of pulmonary involvement, such as pleural effusions, nodules, or cavitations. These imaging modalities can also assist in monitoring disease progression and response to treatment in patients with paragonimiasis. A thorough clinical evaluation, combined with the appropriate diagnostic tests, is essential for accurately diagnosing and managing Paragonimus spp. infections.
💊 Treatment & Recovery
Treatment for Paragonimiasis, caused by the parasitic flatworm Paragonimus, typically involves the use of antiparasitic medications. Among the most commonly prescribed drugs are praziquantel and triclabendazole. These medications work by disrupting the worm’s ability to absorb nutrients, ultimately leading to its death.
In cases where the infection has caused complications such as lung abscesses or pleural effusion, additional treatments may be necessary. Drainage of abscesses or effusions may be required to alleviate symptoms and prevent further damage. In severe cases, surgery may be necessary to remove damaged tissue or provide relief from symptoms.
Recovery from Paragonimiasis can vary depending on the individual’s overall health, the extent of the infection, and the presence of complications. In many cases, symptoms begin to improve within a few weeks of starting treatment. However, it may take several months for full recovery to occur. Follow-up appointments with healthcare providers may be necessary to monitor progress and ensure the infection has been fully eradicated.
🌎 Prevalence & Risk
In the United States, Paragonimiasis is considered to be a rare parasitic infection. However, it has been reported in various states, including Louisiana, where cases have been linked to the consumption of raw or undercooked crayfish. The prevalence of Paragonimiasis in the US is believed to be low due to proper food handling practices and limited exposure to the parasite.
In Europe, Paragonimiasis is also rare, with sporadic cases reported in countries such as France and Spain. The main risk factors for acquiring the infection in Europe include travel to endemic regions and consumption of undercooked crab or crayfish. Health authorities in Europe have raised awareness about the risks of Paragonimiasis among travelers and immigrants from endemic areas.
In Asia, Paragonimiasis is more common, particularly in countries like Japan, South Korea, and the Philippines. The prevalence of the infection in Asia is attributed to the traditional consumption of raw or undercooked freshwater crabs and crayfish, which serve as intermediate hosts for the parasite. Efforts to control Paragonimiasis in Asia include public health education campaigns and proper cooking methods for seafood.
In Africa, Paragonimiasis is considered to be very rare, with only a few reported cases in countries like Nigeria and Cameroon. The low prevalence of the infection in Africa is likely due to limited consumption of freshwater crustaceans and low awareness of the disease. However, the potential for the spread of Paragonimiasis in Africa exists, particularly among populations with a high consumption of raw or undercooked shellfish.
😷 Prevention
Prevention of Paragonimiasis revolves around avoiding consumption of raw or undercooked freshwater crustaceans, such as crabs and crayfish, which are the intermediate hosts of Paragonimus species. Proper cooking of these hosts at temperatures above 135°F for at least five minutes is necessary to kill the parasite larvae. Additionally, individuals should adhere to proper food safety practices, such as ensuring proper hygiene and sanitation in food preparation areas to prevent contamination of dishes with parasite eggs.
In regions where Paragonimiasis is endemic, education and awareness campaigns play a crucial role in preventing the spread of the disease. Public health initiatives can focus on educating communities about the risks of consuming raw or undercooked freshwater crustaceans and the importance of proper food preparation techniques. Encouraging individuals to seek medical treatment promptly if they suspect they have ingested contaminated food can also help prevent the severe manifestations of the disease.
Travelers to endemic regions should be aware of the risks associated with consuming raw or undercooked freshwater crustaceans and take precautions to avoid Paragonimiasis. It is advisable to avoid eating raw or undercooked freshwater crustaceans and opt for well-cooked dishes in areas where the disease is prevalent. Additionally, practicing good hygiene, such as washing hands before meals and after handling raw seafood, can reduce the risk of infection. Consulting with healthcare providers or travel medicine specialists before traveling to endemic regions can also provide valuable information on how to prevent Paragonimiasis.
