ICD-11 code 1F25.11 corresponds to primary cutaneous coccidioidomycosis, a type of fungal infection caused by the Coccidioides fungus. This condition affects the skin and is often acquired through the inhalation of fungal spores found in the soil of certain regions, such as the southwestern United States.
Primary cutaneous coccidioidomycosis typically presents as a skin lesion, which may appear as a raised, red bump that can ulcerate and form a crust. In some cases, the lesion may resemble a boil or abscess and may be accompanied by symptoms such as fever, fatigue, and muscle aches.
Diagnosis of primary cutaneous coccidioidomycosis is usually made based on clinical presentation and confirmed through laboratory tests, such as skin biopsy or fungal culture. Treatment generally involves antifungal medications, such as azoles or amphotericin B, depending on the severity of the infection.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to the ICD-11 code 1F25.11, which represents Primary cutaneous coccidioidomycosis, is 44092007. This specific code in the SNOMED CT terminology system is used to classify the same condition based on clinical findings and characteristics. SNOMED CT, Systematized Nomenclature of Medicine Clinical Terms, is a comprehensive and multilingual clinical healthcare terminology that provides a common language that enables a consistent way of capturing, sharing, and aggregating health data across specialties and sites of care. By using SNOMED CT codes, healthcare professionals can easily communicate and exchange clinical information in a standard format, promoting interoperability and improving patient care. The mapping of ICD-11 codes to SNOMED CT codes allows for a more granular and specific classification of diseases and conditions, facilitating accurate diagnosis and treatment.
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
Primary cutaneous coccidioidomycosis, also known as 1F25.11, is a type of fungal infection caused by the fungus Coccidioides spp. This infection primarily affects the skin, but may also involve the underlying tissues and bone in some cases.
The symptoms of primary cutaneous coccidioidomycosis can vary depending on the severity of the infection. Most commonly, individuals with this condition may experience red, raised skin lesions that may be ulcerated or crusted. These lesions may be painful or itchy and can occur anywhere on the body, but are most commonly found on the face, neck, or upper extremities.
In some cases, primary cutaneous coccidioidomycosis can lead to more severe symptoms such as fever, chills, headache, and joint pain. It is important for individuals experiencing these symptoms to seek medical attention promptly, as untreated infections can potentially lead to complications such as disseminated disease, pneumonia, or systemic fungal infection. Diagnosis of primary cutaneous coccidioidomycosis is typically confirmed through skin biopsy and fungal cultures.
🩺 Diagnosis
Diagnosis of Primary cutaneous coccidioidomycosis (1F25.11) is primarily based on a combination of clinical presentation, imaging studies, and laboratory tests. The most common initial step in diagnosis is to accurately identify characteristic skin lesions associated with the infection, such as erythematous nodules, papules, or ulcers that may present with or without purulent discharge. These skin lesions are often located on exposed areas of the body, particularly the upper chest, neck, and face, and may be accompanied by systemic symptoms such as fever, malaise, and weight loss.
Imaging studies, such as chest X-rays or CT scans, are often performed to evaluate for possible systemic involvement of Coccidioides spp. In cases where pulmonary or disseminated disease is suspected, imaging studies may reveal findings of pulmonary nodules, cavities, or pleural effusions, which can help guide further diagnostic and treatment interventions. Additionally, skin biopsy of the affected lesion may be performed to obtain tissue samples for histopathologic examination, which can provide definitive evidence of Coccidioides infection through the demonstration of characteristic fungal structures (spherules) in tissue specimens.
Laboratory tests play a crucial role in confirming the diagnosis of Primary cutaneous coccidioidomycosis. Culture of tissue samples obtained from skin lesions can allow for isolation and identification of Coccidioides spp., further supporting the diagnosis. serologic tests, such as enzyme immunoassays and complement fixation tests, can also be utilized to detect specific antibodies against Coccidioides antigens in the patient’s blood, providing additional evidence of exposure to the fungus. Molecular techniques, such as polymerase chain reaction (PCR) assays, may also be employed to detect Coccidioides DNA in tissue samples, contributing to the confirmatory diagnosis of the infection.
💊 Treatment & Recovery
Primary cutaneous coccidioidomycosis (1F25.11) is a fungal infection that affects the skin. Treatment often involves antifungal medications, such as fluconazole or itraconazole. These medications are typically taken for several weeks to months, depending on the severity of the infection.
In some cases, surgical intervention may be necessary to remove infected tissue or abscesses. This can help prevent the spread of the infection to deeper tissues or organs. In severe cases, hospitalization may be required for intravenous antifungal treatment and monitoring.
Recovery from primary cutaneous coccidioidomycosis can vary depending on the individual’s overall health and the extent of the infection. It is important for patients to follow their healthcare provider’s recommendations for treatment and follow-up care. Additionally, proper wound care and hygiene practices are essential for preventing reinfection or complications. Patients should be monitored closely for any signs of recurrence or worsening of the infection.
🌎 Prevalence & Risk
In the United States, primary cutaneous coccidioidomycosis, coded as 1F25.11, is more prevalent in regions where the fungus Coccidioides immitis is endemic, such as the southwestern states of Arizona, California, Nevada, New Mexico, and Texas. The incidence of this fungal infection has been increasing in recent years, likely attributed to factors such as climate change and population growth in endemic regions. Individuals who work or live in dusty environments, such as construction workers and agricultural workers, are at higher risk for contracting primary cutaneous coccidioidomycosis.
In Europe, primary cutaneous coccidioidomycosis is extremely rare, as the fungus Coccidioides immitis is not endemic to this region. Cases of the infection in Europe are typically seen in individuals who have traveled to or immigrated from endemic regions, such as the southwestern United States. Due to the limited exposure to the fungus in Europe, healthcare providers may have limited experience in diagnosing and treating primary cutaneous coccidioidomycosis, potentially leading to delayed or missed diagnoses.
In Asia, primary cutaneous coccidioidomycosis is also rare, as the fungus Coccidioides immitis is not endemic to this region. Similar to Europe, cases of the infection in Asia are usually seen in individuals who have traveled to or immigrated from endemic regions, such as the southwestern United States. Due to the limited exposure to the fungus in Asia, healthcare providers may have limited knowledge of the disease, which may result in challenges in diagnosing and managing cases of primary cutaneous coccidioidomycosis.
In Africa, primary cutaneous coccidioidomycosis is exceptionally rare, as the fungus Coccidioides immitis is not endemic to this region. Cases of the infection in Africa are typically linked to travel or immigration from endemic regions, such as the southwestern United States. Healthcare providers in Africa may have limited experience in diagnosing and treating primary cutaneous coccidioidomycosis, which could lead to delays in diagnosis and appropriate management of the infection.
😷 Prevention
Primary cutaneous coccidioidomycosis, also known as 1F25.11, is a fungal infection caused by the inhalation of spores from the Coccidioides immitis or Coccidioides posadasii fungi. While there is no foolproof way to completely prevent the disease, there are several measures that can be taken to reduce the risk of infection.
First and foremost, individuals living in or traveling to areas where Coccidioides fungi are endemic should be aware of the environmental conditions that are conducive to the growth of these organisms. These include arid regions with sandy soil, such as the southwestern United States and parts of Central and South America. By avoiding or minimizing exposure to these high-risk areas, individuals can significantly reduce their chances of contracting primary cutaneous coccidioidomycosis.
Additionally, individuals should take precautions when engaging in outdoor activities in endemic areas, such as wearing protective clothing, using insect repellent, and avoiding areas with visible signs of dust or soil disturbance. It is also advisable to avoid activities that may disrupt soil, such as construction or agricultural work, as this can release fungal spores into the air and increase the risk of inhalation. By following these simple measures, individuals can reduce their risk of exposure to Coccidioides fungi and decrease the likelihood of developing primary cutaneous coccidioidomycosis.
🦠 Similar Diseases
One disease that bears resemblance to primary cutaneous coccidioidomycosis is extrapulmonary coccidioidomycosis (ICD-10 code B38.7). This condition involves the presence of coccidioidal infection in areas outside of the lungs, such as the skin, bones, joints, or central nervous system. Extrapulmonary coccidioidomycosis can manifest as skin lesions or abscesses, similar to primary cutaneous coccidioidomycosis, and may also present with systemic symptoms like fever and fatigue.
Another disease that shares similarities with primary cutaneous coccidioidomycosis is disseminated coccidioidomycosis (ICD-10 code B38.1). This condition occurs when the coccidioidal infection spreads beyond the lungs to affect multiple organs throughout the body. Patients with disseminated coccidioidomycosis may experience skin lesions, joint pain, and systemic symptoms such as weight loss and night sweats. Like primary cutaneous coccidioidomycosis, disseminated coccidioidomycosis can be challenging to diagnose and treat.
A related disease to primary cutaneous coccidioidomycosis is subcutaneous coccidioidomycosis (ICD-10 code B38.4). This form of the infection primarily involves the subcutaneous tissues beneath the skin, presenting as nodules or abscesses. Subcutaneous coccidioidomycosis can result from direct inoculation of the fungus into the skin, often through traumatic injury or surgery. While this condition is distinct from primary cutaneous coccidioidomycosis in its presentation, both diseases share a common etiology and require antifungal therapy for resolution.
