ICD-11 code 1C1D.1 refers to the classification for secondary yaws. Yaws is a chronic infectious disease caused by the bacterium Treponema pallidum subspecies pertenue. This disease is primarily found in rural tropical areas with poor sanitation and overcrowding.
Secondary yaws occurs when the primary infection is left untreated or inadequately treated. This stage of the disease is characterized by the spread of lesions throughout the body, affecting the skin, bones, and mucous membranes. Without proper medical intervention, secondary yaws can lead to severe disfigurement and disability.
The classification of secondary yaws under ICD-11 code 1C1D.1 helps medical professionals accurately diagnose and treat patients with this specific stage of the disease. This code also aids in tracking and reporting cases of yaws to public health authorities for surveillance and control efforts.

#️⃣ Coding Considerations
The equivalent SNOMED CT code for ICD-11 code 1C1D.1 (Secondary yaws) is 307616000. This code is specifically used to classify cases of secondary yaws, which is a chronic infectious disease caused by the spirochete bacterium Treponema pertenue. Yaws primarily affects the skin and bones, leading to disfiguring lesions and progressive destruction of tissue. The condition is typically spread through direct contact with the lesions of an infected person.
The SNOMED CT code 307616000 allows healthcare providers to accurately document and monitor cases of secondary yaws within their patient populations. By using standardized codes like this, medical professionals can ensure consistency in classification and reporting, which is essential for epidemiological surveillance and research efforts. This code facilitates efficient communication and data exchange among healthcare providers, researchers, and institutions, ultimately contributing to better understanding and management of secondary yaws.
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 1C1D.1 (Secondary Yaws) typically appear between one to six months after the initial infection with the yaws bacterium, Treponema pallidum subsp. pertenue. The primary lesion, known as the mother yaw, may have healed by this point, but the secondary stage of yaws presents with widespread skin lesions that are typically painless and non-itchy.
These skin lesions are a characteristic feature of secondary yaws and may vary in appearance, ranging from papules, nodules, and plaques to moist ulcers and thickened areas of skin. These lesions often occur on the face, legs, buttocks, and palms of the hands, but can also affect any other part of the body. The lesions can be highly contagious, especially when they are moist and exuding discharge.
In addition to skin lesions, individuals with secondary yaws may develop bone and joint abnormalities, such as painless swelling of the long bones, particularly those in the legs. This condition, known as goundou, can cause deformities and disabilities if left untreated. Other symptoms of secondary yaws can include fever, malaise, and generalized lymphadenopathy, as the bacterium spreads throughout the body via the bloodstream.
🩺 Diagnosis
Diagnosis of 1C1D.1, also known as secondary yaws, typically involves a physical examination to look for characteristic symptoms such as skin lesions, bone deformities, and mucous patches. The presence of these signs, along with a history of exposure to yaws, can help healthcare providers in making a preliminary diagnosis.
Laboratory tests such as serologic tests, dark-field microscopy, and polymerase chain reaction (PCR) may be conducted to confirm the diagnosis of secondary yaws. Serologic tests measure the presence of antibodies against the bacteria responsible for yaws, while dark-field microscopy can identify the presence of spirochetes in skin lesions. PCR tests can also be used to detect the genetic material of the yaws bacteria in samples taken from skin lesions or swabs.
Skin biopsies may be performed in cases where the diagnosis is uncertain or to rule out other conditions that may resemble secondary yaws. Histopathological examination of the biopsy samples can reveal the presence of spirochetes and aid in confirming the diagnosis. In some instances, imaging studies such as X-rays or ultrasounds may be used to assess bone involvement and detect any structural abnormalities associated with secondary yaws.
💊 Treatment & Recovery
Treatment and recovery methods for 1C1D.1 (Secondary yaws) typically involve a combination of antibiotic therapy and good wound care. The primary antibiotic used for treating yaws is penicillin or a related antibiotic such as doxycycline. These antibiotics are administered over a period of one to two weeks to ensure the infection is fully cleared from the body. Additionally, wound care is important in the management of secondary yaws to prevent secondary infections and promote healing.
In cases where patients are allergic to penicillin, alternative antibiotics such as erythromycin or azithromycin may be used. It is important for healthcare providers to monitor patients closely during treatment to ensure the antibiotics are effective in clearing the infection. Following completion of antibiotic therapy, patients may be advised to undergo periodic follow-up evaluations to monitor for any signs of recurrence or complications.
In addition to antibiotic therapy and wound care, educating patients on good hygiene practices is essential in preventing the spread of yaws to others. Patients should be instructed on the importance of washing their hands regularly and maintaining cleanliness to prevent the transmission of the infection. By following these treatment and recovery methods, patients with secondary yaws can expect a full recovery and a reduced risk of complications.
🌎 Prevalence & Risk
In the United States, Secondary yaws (1C1D.1) is a rare condition with very low prevalence. Due to the effectiveness of healthcare systems and the implementation of public health measures, cases of yaws are extremely uncommon in the US. The disease is mainly found in tropical regions with poor sanitation and limited access to healthcare, making the likelihood of transmission to the US population minimal.
In Europe, the prevalence of Secondary yaws is virtually non-existent. The disease has been eradicated in most European countries through organized screening and treatment programs. The implementation of sanitation systems and healthcare infrastructure has effectively prevented the spread of yaws in Europe. Cases that do occur are usually imported from other regions with a higher prevalence of the disease.
In Asia, the prevalence of Secondary yaws varies depending on the subregion. In some countries, yaws is endemic in rural areas with limited access to healthcare and poor sanitation. However, in more developed Asian countries, the prevalence of yaws is very low due to comprehensive public health initiatives and improved healthcare services. Efforts to eradicate yaws in Asia have been successful in many regions, leading to a decline in the number of reported cases.
In Africa, yaws remains a significant public health concern, particularly in rural communities with inadequate access to healthcare. The prevalence of Secondary yaws is highest in sub-Saharan Africa, where the disease is endemic in many countries. Efforts to control and eliminate yaws in Africa have been ongoing, with some success in reducing the number of cases through targeted treatment and prevention programs. The persistence of yaws in Africa underscores the importance of continued efforts to combat the disease and improve health outcomes in affected populations.
😷 Prevention
To prevent 1C1D.1, or secondary yaws, it is important to address the primary infection of yaws in order to prevent the occurrence of secondary cases. Primary yaws is typically treated with a course of antibiotics, such as penicillin or azithromycin, which can help to eradicate the bacterium that causes the infection. This treatment can also reduce the risk of transmission to others and prevent the development of secondary yaws.
Additionally, it is crucial to improve overall hygiene and sanitation practices in endemic areas to prevent the spread of yaws and other related diseases. Promoting regular handwashing, providing access to clean water sources, and encouraging proper wound care can all help to reduce the transmission of yaws and prevent the development of secondary cases. Education and awareness campaigns can also play a critical role in preventing the spread of yaws and reducing the incidence of secondary infections.
Furthermore, efforts to control the spread of yaws through public health interventions, such as mass drug administration campaigns and active case finding, can help to identify and treat cases of yaws early on before they progress to secondary infections. These interventions can help to reduce the burden of yaws in endemic areas and prevent the development of secondary cases. By implementing a combination of treatment, hygiene promotion, and public health interventions, it is possible to prevent the occurrence of 1C1D.1 and reduce the impact of yaws on affected populations.
🦠 Similar Diseases
Secondary yaws, coded as 1C1D.1, is a specific type of non-venereal treponemal infection that presents with ulcerative lesions on the skin. The disease is caused by the bacterium Treponema pertenue and is most commonly transmitted through direct contact with infected lesions. While secondary yaws is the most prevalent manifestation of the disease, there are other diseases that share similar characteristics in terms of transmission and clinical presentation.
One such disease is primary yaws, coded as 1C00.0. Like secondary yaws, primary yaws is caused by infection with Treponema pertenue. However, unlike secondary yaws which occurs after an initial infection with the bacterium, primary yaws represents the initial exposure and infection with the pathogen. Clinical manifestations of primary yaws include painless ulcers on the skin, typically on the limbs, face, or genital area.
Another related disease is syphilis, coded as 1C10.0. Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. While both yaws and syphilis are caused by treponemal infections, they differ in terms of their mode of transmission and clinical presentation. Syphilis can present with a wide range of symptoms, including genital ulcers, skin rashes, and systemic manifestations if left untreated.
Endemic syphilis, coded as 1C12, is a chronic form of treponemal infection that shares similarities with yaws in terms of its endemic nature and predilection for certain geographic regions. Endemic syphilis is caused by infection with Treponema pallidum pertenue, similar to yaws, but typically manifests with milder symptoms and a slower progression of disease. Like yaws, endemic syphilis can lead to disfigurement and long-term complications if left untreated.
In conclusion, while secondary yaws, coded as 1C1D.1, is a distinct form of treponemal infection, there are other diseases such as primary yaws, syphilis, and endemic syphilis that share similar characteristics in terms of transmission routes and clinical manifestations. It is important for healthcare providers to be aware of these related diseases in order to provide prompt and appropriate treatment to affected individuals.
