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 represents a medical visit or encounter where you received screening tests to check for infections that are transmitted through sexual contact, such as chlamydia, gonorrhea, syphilis, HIV, or other sexually transmitted infections. This is preventive care to detect infections early, even when you don't have symptoms. The screening may involve blood tests, urine tests, or swab samples depending on which infections are being tested for.

Additional Information

This is routine preventive screening that is often covered by insurance. The specific tests performed may vary based on your age, gender, sexual history, and risk factors. Regular STI screening is an important part of sexual health maintenance.
