ICD-11 code 1F42.Z represents a specific type of malaria known as Plasmodium malariae malaria without complication. This code is used by healthcare providers and researchers to track and classify cases of malaria caused by the Plasmodium malariae parasite.
Malaria is a mosquito-borne infectious disease that affects millions of people worldwide each year. Plasmodium malariae is one of the four main types of parasites that cause malaria in humans, alongside Plasmodium falciparum, Plasmodium vivax, and Plasmodium ovale.
When the code specifies “without complication,” it means that the malaria caused by Plasmodium malariae is not presenting any additional complications or severe symptoms. This distinction is important for accurately diagnosing and treating patients with malaria, as different types of malaria may require different treatment approaches.

#️⃣ Coding Considerations
The SNOMED CT equivalent for ICD-11 code 1F42.Z, which denotes Plasmodium malariae malaria without complication, is 715519004. This SNOMED CT code specifically identifies the presence of Plasmodium malariae without any associated complications. It provides a standardized way for healthcare professionals to document and communicate this specific diagnosis within electronic health records and health information systems. By using this code, healthcare providers can ensure accurate and consistent representation of the patient’s condition, facilitating better care coordination and decision-making. The use of standardized code sets like SNOMED CT aids in interoperability and data exchange across different healthcare settings and systems, ultimately improving the quality of patient care and advancing public health initiatives.
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 1F42.Z (Plasmodium malariae malaria without complication) typically appear within a few weeks after the bite of an infected Anopheles mosquito. These symptoms may include fever, chills, sweats, muscle aches, headaches, and fatigue. In some cases, individuals may also experience nausea, vomiting, and diarrhea.
The periodic nature of the symptoms is a distinguishing characteristic of Plasmodium malariae malaria. Patients may have recurrent episodes of fever and other symptoms every 72 hours, which corresponds to the life cycle of the parasite. The fever may spike every three days, followed by a period of feeling relatively well before the symptoms return.
As the disease progresses, patients may develop anemia due to the destruction of red blood cells by the parasite. This can lead to symptoms such as weakness, pallor, and shortness of breath. If left untreated, Plasmodium malariae malaria without complication can become severe and potentially life-threatening. Early diagnosis and prompt treatment are crucial in preventing complications.
🩺 Diagnosis
Diagnosis of Plasmodium malariae malaria without complications typically involves a combination of clinical evaluation, laboratory tests, and travel history. Common initial symptoms may include fever, chills, headache, and flu-like illness. A detailed assessment of the patient’s history, such as recent travel to endemic areas, is crucial in suspecting malaria infection.
Laboratory tests are essential for confirming the diagnosis of Plasmodium malariae malaria. Blood smears are commonly used to identify the presence of malaria parasites in the patient’s blood. Special staining techniques, such as Giemsa staining, are often employed to differentiate between different species of Plasmodium parasites. Additionally, molecular tests, such as polymerase chain reaction (PCR), may be utilized for accurate species identification.
It is important to note that Plasmodium malariae malaria can sometimes present with atypical symptoms or low parasite densities, making diagnosis challenging. In such cases, repeat blood smears may be necessary to detect the presence of the parasite. Clinicians should also consider the possibility of mixed infections with other species of Plasmodium parasites, which may require additional testing and treatment considerations. Effective diagnosis and prompt treatment are crucial in preventing complications and severe manifestations of malaria.
💊 Treatment & Recovery
Treatment for Plasmodium malariae malaria without complication (1F42.Z) typically includes anti-malarial medication. Chloroquine is often the first-line treatment for uncomplicated cases of P. malariae malaria. However, in some regions where chloroquine resistance is common, other medications such as atovaquone-proguanil or quinine plus doxycycline may be used.
Patients with P. malariae malaria should be closely monitored for any signs of complications or worsening condition. In severe cases, hospitalization may be necessary for more intensive care and monitoring. In addition to anti-malarial medication, supportive care such as hydration, rest, and management of symptoms like fever and chills may be recommended to aid in recovery.
Following treatment, patients should be monitored closely to ensure the infection is fully cleared. Repeat blood tests may be necessary to confirm that the parasite has been successfully eradicated. Additionally, patients should be educated on how to prevent future infections through the use of mosquito repellent, bed nets, and other methods to avoid mosquito bites. Regular follow-up appointments may be necessary to monitor the patient’s recovery and ensure there are no lingering symptoms or complications.
🌎 Prevalence & Risk
In the United States, the prevalence of 1F42.Z (Plasmodium malariae malaria without complication) is quite low compared to other regions of the world. This is primarily due to factors such as a lack of suitable vectors for the transmission of the Plasmodium malariae parasite, as well as effective prevention measures in place to minimize the risk of contracting the disease. Travelers returning from regions where malaria is endemic may contribute to occasional cases reported within the United States.
In Europe, the prevalence of 1F42.Z is also relatively low, with most cases being imported from areas where malaria is more common. Despite being largely considered a non-endemic region for malaria transmission, certain parts of southern Europe may be at higher risk due to proximity to regions where the disease is prevalent. Public health efforts in Europe focus on early detection and treatment of imported cases to prevent local transmission.
In Asia, the prevalence of 1F42.Z varies significantly depending on the region. Countries in Southeast Asia, such as India and Indonesia, have high incidences of Plasmodium malariae malaria without complication due to their tropical climates and suitable breeding grounds for malaria-carrying mosquitoes. Other parts of Asia, such as Japan and South Korea, have lower prevalence rates due to successful mosquito control programs and widespread use of antimalarial measures.
In Africa, the prevalence of 1F42.Z is highest compared to other regions of the world, with sub-Saharan Africa being the most affected. Factors such as poverty, lack of access to healthcare, and inadequate infrastructure contribute to the high burden of Plasmodium malariae malaria without complication in this region. Efforts to control and eliminate malaria in Africa include the distribution of insecticide-treated bed nets, indoor residual spraying, and access to prompt diagnosis and treatment.
😷 Prevention
To prevent 1F42.Z (Plasmodium malariae malaria without complication, it is essential to implement a combination of strategies aimed at reducing the risk of contracting the disease. One of the most effective preventive measures is to take appropriate antimalarial medication before, during, and after traveling to regions where malaria is prevalent. It is crucial to consult a healthcare provider to determine the most suitable medication based on the specific destination and individual health considerations.
In addition to medication, adopting personal protective measures can also help prevent 1F42.Z. This includes using insect repellent, wearing long-sleeved clothing, and sleeping under mosquito nets treated with insecticide. These measures are particularly important during peak mosquito activity times, such as dawn and dusk, when mosquitoes are most active and likely to transmit the parasite.
Furthermore, travelers should avoid exposure to mosquito bites by staying in accommodations with screens on windows and doors, and by avoiding outdoor activities during peak mosquito activity times. It is also recommended to remove standing water around living quarters, as mosquitoes breed in stagnant water. By implementing a combination of preventive measures, individuals can significantly reduce their risk of contracting 1F42.Z (Plasmodium malariae malaria without complication.
