ICD-11 code 1C11.01 refers to verruga peruana, a medical condition also known as Carrion’s disease. This disease is caused by the bacterium Bartonella bacilliformis, which is transmitted to humans through the bite of infected sandflies. Verruga peruana is characterized by skin lesions that can be either nodular (nodular phase) or wart-like (verrucous phase).
The nodular phase of verruga peruana typically appears about 4-8 weeks after infection and is marked by the development of painless red or purplish nodules on the skin. These nodules can ulcerate and release a bloody discharge, but they usually heal spontaneously within a few weeks. In contrast, the verrucous phase of the disease occurs several months after the nodular phase and is characterized by the formation of wart-like growths on the skin.
Verruga peruana is endemic to certain regions of South America, particularly in Peru, Ecuador, and Colombia. The disease is most commonly found in rural areas with poor sanitation and where sandflies thrive. Diagnosis of verruga peruana is typically confirmed through a combination of clinical evaluation, microscopic examination of skin lesions, and laboratory testing for the presence of Bartonella bacilliformis infection. Treatment usually involves antibiotics, such as ciprofloxacin or doxycycline, to eliminate the bacteria and prevent complications.

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 1C11.01 (Verruga peruana) typically manifest as small, reddish-brown nodules on the skin that can range in size from a few millimeters to several centimeters in diameter. These nodules are often painless and may appear in clusters on various parts of the body, most commonly on the face, arms, and legs. In some cases, the nodules can become ulcerated and develop a crusty surface.
As the disease progresses, individuals may experience fever, fatigue, and muscle aches. In severe cases, the skin lesions may bleed easily and become infected, leading to the formation of abscesses. The presence of Verruga peruana can also cause anemia due to the destruction of red blood cells by the bacteria Bartonella bacilliformis, which is responsible for causing the disease.
Other symptoms associated with Verruga peruana include enlarged lymph nodes, joint pain, and general malaise. Some individuals may develop a distinctive rash known as miliaria rubra, which consists of small, red papules that itch intensely. Additionally, individuals with compromised immune systems or underlying health conditions may experience more severe symptoms, including respiratory distress or organ failure. Early diagnosis and treatment are crucial in managing the symptoms of Verruga peruana and preventing complications.
🩺 Diagnosis
Diagnosis of 1C11.01 (Verruga peruana) can be challenging due to its resemblance to other skin conditions, such as cutaneous leishmaniasis and nodular vasculitis. Clinical diagnosis is often based on the appearance of the skin lesions, which typically present as erythematous nodules or plaques with a central ulceration. These lesions are commonly located on exposed areas of the body, such as the face, arms, and legs.
Laboratory tests are essential for confirming the diagnosis of Verruga peruana. Microscopic examination of a skin biopsy is often performed to detect the presence of the causative agent, Bartonella bacilliformis. Molecular tests, such as PCR (polymerase chain reaction), can also be used to identify the genetic material of the bacterium in skin samples. Additionally, serological tests, including ELISA (enzyme-linked immunosorbent assay), can detect antibodies against Bartonella bacilliformis in the patient’s blood.
In some cases, imaging studies may be necessary to assess the extent of the infection and its impact on surrounding tissues. Ultrasound and MRI (magnetic resonance imaging) can help evaluate the presence of subcutaneous nodules and any potential complications, such as lymphadenopathy. Overall, a combination of clinical evaluation, laboratory tests, and imaging studies is crucial for accurately diagnosing 1C11.01 (Verruga peruana) and guiding appropriate treatment strategies.
💊 Treatment & Recovery
Treatment for Verruga peruana (1C11.01) typically involves the use of antibiotics such as penicillin or tetracycline. These medications are effective in treating the bacterial infection caused by Bartonella bacilliformis, which is responsible for causing Verruga peruana.
In some cases, patients may also be prescribed antipyretics and analgesics to help manage symptoms such as fever and pain. These medications can provide relief while the body fights off the infection.
Surgical removal of the lesions caused by Verruga peruana may be necessary in severe cases where the lesions are causing discomfort or interfering with daily activities. However, this is not a common treatment option and is typically reserved for extreme cases.
Recovery from Verruga peruana can vary depending on the severity of the infection and the individual’s overall health. With prompt and appropriate treatment, most patients can recover fully and without complications. Patients should follow their healthcare provider’s recommendations for medication compliance and follow-up appointments to ensure a full recovery.
