ICD-11 code 1A61.2 represents primary syphilis of other sites. Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. Primary syphilis occurs when the bacterium enters the body through mucous membranes or breaks in the skin during sexual contact with an infected individual.
Primary syphilis typically manifests as a painless sore, known as a chancre, at the site of infection. In the case of 1A61.2, the code specifies that the primary syphilis lesion is located in a site other than the genitals. This can include areas such as the mouth, anus, or other parts of the body where the bacterium has entered and caused a chancre to develop.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to ICD-11 code 1A61.2, which represents primary syphilis of other sites, is 773111000000109. This alphanumeric code is used for electronic health records and billing purposes to accurately document and track cases of syphilis in patients. By using standardized code systems such as SNOMED CT and ICD-11, healthcare providers can ensure consistency in reporting and data analysis across different healthcare settings. The SNOMED CT code 773111000000109 specifically identifies cases of primary syphilis affecting anatomical sites other than the genitals or anus, allowing for more precise classification and treatment of this infectious disease. It is important for healthcare professionals to be familiar with these code systems in order to correctly diagnose, document, and manage cases of syphilis in patients.
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 syphilis of other sites (1A61.2) refers to the initial stage of syphilis, a sexually transmitted infection caused by the bacterium Treponema pallidum, affecting sites other than the genitals. The hallmark symptom of primary syphilis is the development of a painless sore called a chancre at the site of infection. In cases of primary syphilis of other sites, these chancres can appear on areas such as the mouth, anus, or other parts of the body.
The chancres of primary syphilis typically appear within 3 weeks to 3 months after exposure to the bacterium. These sores are usually firm, round, and painless, making them easy to miss or mistake for other skin conditions. Despite their painless nature, chancres are highly contagious and can easily transmit the syphilis infection to sexual partners through direct contact with the sore.
In addition to chancres, individuals with primary syphilis of other sites may also experience other symptoms such as swollen lymph nodes near the site of infection. These enlarged lymph nodes, known as lymphadenopathy, are a common immune response to the presence of the bacterium Treponema pallidum in the body. Swelling and tenderness of the lymph nodes can be a sign of an active syphilis infection and should prompt further evaluation by a healthcare provider.
🩺 Diagnosis
Diagnosis of primary syphilis of other sites, coded as 1A61.2, involves a combination of clinical evaluation and laboratory testing. Clinical diagnosis is made based on physical examination, which may reveal the presence of a painless chancre at the site of infection. A thorough examination of the patient’s medical history and sexual behavior is also necessary to assess risk factors.
Laboratory testing plays a crucial role in confirming the diagnosis of primary syphilis. Serologic tests, such as the Venereal Disease Research Laboratory (VDRL) or Rapid Plasma Reagin (RPR) tests, are commonly used to detect the presence of antibodies against Treponema pallidum, the bacterium that causes syphilis. These tests can help confirm the diagnosis and determine the stage of the infection.
In cases where primary syphilis is suspected but serologic tests are negative, dark-field microscopy may be used to directly visualize the spirochetes in samples taken from the chancre. This method can provide a definitive diagnosis, especially in early stages of infection when antibody levels may be low. Additionally, molecular tests, such as polymerase chain reaction (PCR), may be used to detect T. pallidum DNA in clinical samples. These tests can be helpful in cases where traditional serologic tests are inconclusive.
💊 Treatment & Recovery
Treatment for primary syphilis of other sites (1A61.2) typically involves a course of antibiotic therapy, most commonly with penicillin. The specific type of antibiotic and duration of treatment will depend on the patient’s overall health, the stage of the infection, and any potential drug allergies.
In cases where patients have a known allergy to penicillin, alternative antibiotics such as doxycycline or azithromycin may be prescribed. It is important for patients to adhere to the prescribed treatment regimen and to follow up with their healthcare provider as scheduled to ensure the infection is eradicated.
Recovery from primary syphilis of other sites typically occurs within a few weeks to a few months following the completion of antibiotic treatment. It is important for patients to abstain from sexual activity during this time period and to notify their partners so that they can also be tested and treated if necessary. Regular follow-up appointments and testing may be recommended to monitor for any signs of treatment failure or recurrence.
🌎 Prevalence & Risk
In the United States, the prevalence of 1A61.2 (Primary syphilis of other sites) is relatively low compared to other sexually transmitted infections. However, the exact prevalence data can vary depending on the region and population demographics. Primary syphilis is generally more common in urban areas and among certain high-risk groups, such as men who have sex with men and individuals with multiple sexual partners.
In Europe, the prevalence of primary syphilis of other sites is also relatively low, but there has been a slight increase in recent years. This increase has been attributed to factors such as changes in sexual behavior, lack of awareness about the infection, and inadequate access to healthcare services. Primary syphilis is more common in certain European countries with higher rates of unprotected sex and limited resources for prevention and treatment.
In Asia, the prevalence of primary syphilis of other sites varies greatly across different countries and regions. In some parts of Asia, the infection is relatively rare due to strong public health measures and awareness campaigns. However, in other areas, particularly in low-income urban settings, the prevalence of primary syphilis can be higher due to factors such as poverty, limited access to healthcare, and cultural taboos around discussing sexual health.
In Africa, the prevalence of primary syphilis of other sites is generally higher compared to other regions. This is due to a combination of factors, including high rates of poverty, limited access to healthcare services, and cultural beliefs that may discourage seeking medical treatment for sexually transmitted infections. Primary syphilis is a significant public health concern in many African countries, and efforts to improve prevention, diagnosis, and treatment are essential to reduce the burden of the infection.
😷 Prevention
Prevention of 1A61.2 (Primary syphilis of other sites) can be achieved through various measures. One of the most effective ways to prevent primary syphilis is to practice safe sex. This includes using condoms consistently and correctly during sexual intercourse to reduce the risk of transmitting or contracting the infection.
Another important aspect of preventing primary syphilis is to undergo regular screening and testing for sexually transmitted infections. This can help detect syphilis at an early stage and prevent its progression to more severe complications. Individuals who are sexually active, particularly those with multiple partners, should discuss the need for regular testing with their healthcare provider.
Education and awareness are also key components in preventing primary syphilis. By understanding the risks associated with unprotected sex and the importance of getting tested, individuals can make informed decisions about their sexual health. Additionally, healthcare providers play a crucial role in educating their patients about syphilis prevention and the importance of early detection and treatment. By working together to promote safe sex practices and regular testing, the incidence of primary syphilis can be reduced.
🦠 Similar Diseases
1A61.2 refers to primary syphilis of other sites. Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum, and primary syphilis is characterized by the appearance of a painless sore or ulcer, known as a chancre, at the site of infection. The code 1A61.2 specifically denotes cases of primary syphilis affecting sites other than the genitals or mouth.
Another disease that may present similarly to primary syphilis but is caused by a different pathogen is chancroid. Chancroid is a bacterial sexually transmitted infection caused by Haemophilus ducreyi, which can also lead to the formation of painful ulcers on the genitals. While chancroid and syphilis share similarities in their clinical presentation, they are distinct diseases requiring different treatments.
Genital herpes is another condition that can manifest with symptoms similar to those of primary syphilis. Genital herpes is caused by the herpes simplex virus (HSV) and presents with painful blisters or sores on the genitals or rectal area. Unlike syphilis, herpes infections are recurrent and can be managed with antiviral medications to control outbreaks and reduce transmission risk.
