CPT® Code 87810

The CPT® Code 87810 refers to a diagnostic procedure that involves the detection of the infectious agent Chlamydia trachomatis through an immunoassay method, specifically utilizing direct optical observation. This rapid, qualitative test is designed to identify the presence of Chlamydia trachomatis, a bacterium responsible for a common sexually transmitted disease (STD). Often asymptomatic, this infection can lead to significant health complications, particularly in women, where it may cause irreversible damage to the reproductive system, potentially resulting in infertility. In contrast, while men may experience symptoms such as burning and itching in the urethra, they are less likely to suffer long-term reproductive damage from the infection. The procedure typically involves a swabbing technique, where the exocervix is first swabbed to clear away excess mucus, followed by the collection of columnar or cuboidal cells from the endocervical canal, which serve as the primary reservoir for Chlamydia organisms. The collected specimen is then processed with specific reagents and incubated to facilitate the detection of the antigen. The final step involves adding the sample to a test cassette, where a color change indicates the presence of the C. trachomatis antigen, confirming the infection.
