What is the ICD-10 code for treatment of Chlamydia (Chlamydia trachomatis) when a partner is positive?

From the Guidelines

The ICD-10 code for contact with and (suspected) exposure to sexually transmitted diseases is Z20.2, which is appropriate when treating a patient whose partner has tested positive for chlamydia. This is considered presumptive treatment. The recommended treatment regimen is doxycycline 100 mg orally twice daily for 7 days, or alternatively, azithromycin 1 gram orally as a single dose, as outlined by the Centers for Disease Control and Prevention (CDC) 1. Patients should abstain from sexual activity for 7 days after single-dose therapy or until completion of a 7-day regimen, to minimize transmission and reinfection 1. It's essential to test the patient for chlamydia as well, even when providing presumptive treatment. Additionally, screening for other STIs including HIV, syphilis, gonorrhea, and hepatitis B is recommended since co-infections are common. Some key points to consider when treating a patient whose partner has tested positive for chlamydia include:

• Providing presumptive treatment with doxycycline or azithromycin
• Ensuring the patient abstains from sexual activity for 7 days after treatment
• Testing the patient for chlamydia and other STIs
• Treating partners simultaneously when possible to prevent reinfection
• Following up with patients to ensure treatment completion and address any persistent symptoms. The CDC regularly updates its recommendations, so clinicians should access the CDC Web site to obtain the most up-to-date information 1.

From the Research

ICD-10 Code for Chlamydia Treatment

• The ICD-10 code for chlamydia treatment is not explicitly mentioned in the provided studies 2, 3, 4, 5, 6.

Treatment Options for Chlamydia

• Azithromycin and doxycycline are two commonly used antibiotics for treating chlamydia 2, 3, 4, 5, 6.
• Doxycycline has been shown to be more effective than azithromycin in treating rectal chlamydia infections in men who have sex with men (MSM) 2, 3.
• In women, doxycycline has also been shown to be more effective than azithromycin in treating rectal chlamydia infections 4.

Partner Treatment

• If a partner has tested positive for chlamydia, it is essential to treat them as well to prevent reinfection 6.
• The treatment options for partners are the same as those for the infected individual, namely azithromycin or doxycycline 6.

Important Considerations

• The choice of antibiotic treatment should be based on the individual's medical history, allergy status, and other factors 6.
• It is crucial to complete the full treatment course to ensure effective treatment and prevent antibiotic resistance 6.
