Z202 - Contact with or exposure to sexually transmitted infections

International Classification of Diseases

Last updated: 10/3/2025

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code indicates that you have been exposed to or had contact with someone who has a sexually transmitted infection (STI). This doesn't mean you have the infection yourself - it's used when there's a reason to test or monitor you because of potential exposure. This might occur after unprotected sexual contact with someone who has an STI, or when a sexual partner has been diagnosed with an infection. Healthcare providers use this code when ordering tests or providing preventive care related to possible STI exposure.

Additional Information

This is a contact/exposure code, not a diagnosis of infection. Testing and follow-up care will depend on the type of exposure and provider recommendations. Early detection and treatment of STIs is important for health outcomes.
