Code Description

ICD-10 A56.2 is a billable code used to indicate a diagnosis of chlamydial cervicitis.

Key Diagnostic Point:

Chlamydial cervicitis is an inflammation of the cervix caused by the bacterium Chlamydia trachomatis, a common sexually transmitted infection (STI). It often presents with symptoms such as abnormal vaginal discharge, bleeding between periods, and pain during intercourse. However, many individuals may remain asymptomatic, which can lead to delayed diagnosis and treatment. The condition is particularly prevalent among sexually active women under the age of 25. If left untreated, chlamydial cervicitis can lead to serious complications, including pelvic inflammatory disease (PID), infertility, and increased risk of HIV transmission. Diagnosis typically involves nucleic acid amplification tests (NAATs) or other laboratory tests to detect the presence of Chlamydia trachomatis. Treatment usually consists of antibiotics, with azithromycin or doxycycline being the most commonly prescribed. Contact tracing is essential to prevent reinfection and further spread of the infection, as partners of infected individuals should also be tested and treated if necessary.
