ICD-11 code 1F50 refers to Acanthamoebiasis, an infectious disease caused by the Acanthamoeba species of amoeba. This pathogen can be found in soil, air, and water sources such as tap water, swimming pools, and contact lens solutions. Acanthamoebiasis most commonly affects the skin, eyes, and central nervous system, leading to symptoms such as skin lesions, eye inflammation, and encephalitis.
Infections typically occur through contact with contaminated water or soil, particularly through activities like swimming, using improperly disinfected contact lenses, or engaging in agricultural work. Acanthamoebiasis can also occur as a result of trauma to the skin or eyes, which allows the amoebas to enter the body. Once inside, the amoebas can cause tissue destruction and inflammation, leading to a variety of symptoms depending on the site of infection.
Diagnosis of Acanthamoebiasis can be challenging, as the symptoms can mimic those of other conditions and the amoebas are not easily detected in standard laboratory tests. Treatment typically involves a combination of antimicrobial medications, such as pentamidine or sulfadiazine, along with supportive care to manage symptoms. Early detection and treatment are crucial in preventing complications and improving outcomes for individuals with Acanthamoebiasis.

#️⃣ Coding Considerations
The equivalent SNOMED CT code for the ICD-11 code 1F50, which corresponds to the diagnosis of Acanthamoebiasis, is 3964000. This code is used to classify cases of Acanthamoebiasis within the SNOMED CT system, providing a standardized way to document and track this rare parasitic infection. SNOMED CT, the Systematized Nomenclature of Medicine Clinical Terms, is a multilingual clinical healthcare terminology set that is used globally for the electronic exchange of clinical health information. By mapping ICD-11 codes to SNOMED CT codes, healthcare providers and researchers can ensure consistency and interoperability in documenting and analyzing cases of Acanthamoebiasis. This harmonized coding system helps facilitate accurate reporting, research, and decision-making related to this potentially serious infectious 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
Acanthamoebiasis is a rare infection caused by the Acanthamoeba amoeba. This infection typically occurs in individuals with weakened immune systems, such as those with HIV/AIDS or undergoing organ transplants. The symptoms of acanthamoebiasis can vary depending on the location of the infection within the body.
Infections of the skin and eyes are the most common manifestations of acanthamoebiasis. Symptoms of skin infections may include red, painful sores that do not heal, while eye infections can cause severe pain, redness, and blurred vision. In some cases, the amoeba can also enter the central nervous system, leading to more severe symptoms such as headaches, stiff neck, nausea, and confusion.
In rare cases, acanthamoebiasis can also affect the respiratory system, causing symptoms such as cough, shortness of breath, and chest pain. Additionally, the infection can spread to other organs, leading to symptoms specific to each affected area. If left untreated, acanthamoebiasis can be life-threatening, so prompt diagnosis and treatment are crucial in managing this infection.
🩺 Diagnosis
Diagnosis methods for Acanthamoebiasis typically involve a combination of clinical evaluation, laboratory tests, and imaging studies. Acanthamoebiasis primarily affects the eye, skin, and central nervous system, causing a range of symptoms including eye pain, redness, and neurological deficits. Diagnosis begins with a thorough physical exam and medical history to identify potential risk factors and symptoms consistent with Acanthamoebiasis.
Laboratory tests play a crucial role in confirming the diagnosis of Acanthamoebiasis. Microscopic examination of clinical samples such as corneal scrapings, skin biopsies, or cerebrospinal fluid can reveal the presence of Acanthamoeba cysts or trophozoites. Culture of samples on specific media can help grow and identify the organism, while polymerase chain reaction (PCR) assays can detect Acanthamoeba DNA with high sensitivity and specificity.
Imaging studies are often used to assess the extent and severity of organ involvement in Acanthamoebiasis. For ocular Acanthamoebiasis, techniques such as optical coherence tomography (OCT) or confocal microscopy can provide detailed images of corneal lesions and aid in diagnosis. In cases of central nervous system involvement, neuroimaging studies like computed tomography (CT) or magnetic resonance imaging (MRI) may reveal brain lesions or abscesses associated with Acanthamoebiasis. Collaborative efforts between clinicians, microbiologists, and radiologists are essential in accurately diagnosing and managing Acanthamoebiasis.
💊 Treatment & Recovery
Treatment and recovery methods for Acanthamoebiasis, caused by the protozoan parasite Acanthamoeba, vary depending on the severity of the infection and the organs affected. The mainstay of treatment includes a combination of antimicrobial medications such as pentamidine, sulfadiazine, and fluoroquinolones. These drugs work by targeting the parasite and stopping its growth and replication within the body.
In severe cases of Acanthamoebiasis, where the infection has spread to the brain or other vital organs, surgical intervention may be necessary to remove infected tissues and improve the efficacy of antimicrobial therapy. This is particularly important in cases of granulomatous amebic encephalitis (GAE), a rare but life-threatening form of the disease that affects the central nervous system. Surgery can help reduce the parasite burden and prevent further damage to the affected organs.
In addition to antimicrobial therapy and surgery, supportive care is essential in the management of Acanthamoebiasis. Patients may require intensive care, including intravenous fluids, pain management, and monitoring of vital signs to ensure their stability during treatment. Physical therapy and rehabilitation may also be needed to help patients regain strength and mobility following severe infections that have caused muscle weakness or paralysis. Early diagnosis and prompt initiation of treatment are crucial in improving the prognosis for individuals with Acanthamoebiasis.
🌎 Prevalence & Risk
In the United States, the prevalence of Acanthamoebiasis is relatively low compared to other regions. Cases of Acanthamoebiasis are sporadic, with most infections occurring in individuals who have compromised immune systems or who engage in activities that increase their risk of exposure to the Acanthamoeba organism.
In Europe, Acanthamoebiasis is also considered to be a rare disease, with most cases occurring in immunocompromised individuals. The prevalence of Acanthamoebiasis in Europe is not well-documented, as cases are often underreported or misdiagnosed due to the non-specific symptoms associated with the infection.
In Asia, the prevalence of Acanthamoebiasis is thought to be higher than in Western countries. This is believed to be due to factors such as poor sanitation, inadequate access to clean water sources, and environmental conditions that favor the survival and growth of the Acanthamoeba organism. However, limited data is available on the exact prevalence of Acanthamoebiasis in Asia, as cases may go undiagnosed or untreated.
In Africa, the prevalence of Acanthamoebiasis is not well-documented, with few reported cases in the literature. Due to limited access to healthcare and diagnostic facilities in many parts of Africa, cases of Acanthamoebiasis may be underreported or mistaken for other diseases with similar symptoms. Further research and surveillance are needed to better understand the prevalence of Acanthamoebiasis in Africa and other regions where the disease may be under-recognized.
😷 Prevention
Preventing 1F50 (Acanthamoebiasis) involves several key steps. One important measure is to avoid using tap water for activities such as rinsing contact lenses, bathing, or swimming in bodies of water. This is because the amoebas that cause Acanthamoebiasis can be found in tap water sources and can enter the body through the eyes, nose, or mouth. Another important precaution is to practice good hygiene, particularly when it comes to contact lens care. Contact lenses should be properly cleaned and disinfected according to manufacturer instructions to reduce the risk of infection.
Furthermore, it is essential to avoid exposure to contaminated water sources such as hot tubs, swimming pools, and lakes. These environments can harbor amoebas that cause Acanthamoebiasis. When swimming or engaging in water activities, it is advisable to wear goggles or protective eyewear to prevent contact with contaminated water. Additionally, individuals with weakened immune systems should take extra precautions to reduce their risk of contracting Acanthamoebiasis, as they may be more susceptible to infection. Overall, practicing good hygiene, avoiding contact with contaminated water sources, and taking preventive measures when engaging in water activities can help reduce the risk of Acanthamoebiasis.
🦠 Similar Diseases
One disease similar to 1F50 (Acanthamoebiasis) is primary amoebic meningoencephalitis (PAM), caused by the free-living amoeba Naegleria fowleri. This rare but severe disease affects the brain and spinal cord, leading to symptoms such as headache, fever, nausea, and stiff neck. PAM is typically acquired through swimming in warm freshwater lakes and rivers where the amoeba can thrive.
Another related disease is granulomatous amebic encephalitis (GAE), caused by the amoeba Balamuthia mandrillaris. GAE is a rare and often fatal disease that affects the brain, skin, and other organs. Symptoms of GAE may include headache, confusion, seizures, and skin lesions. The amoeba is believed to enter the body through broken skin or the respiratory tract.
Additionally, disseminated acanthamebiasis is a systemic infection caused by the amoeba Acanthamoeba. This condition can affect multiple organs, including the skin, eyes, lungs, and brain. Symptoms of disseminated acanthamebiasis may vary depending on the organs involved, but can include skin ulcers, eye pain, shortness of breath, and neurological deficits. Treatment for disseminated acanthamebiasis is challenging due to the organism’s resistance to many antimicrobial agents.
