A74.9

What This Code Means

A chlamydial infection is a sexually transmitted bacterial infection caused by Chlamydia trachomatis, but the specific location or type of infection is not documented. This code is used when a chlamydial infection is confirmed but the medical record lacks details about which body system is affected.

Coding Tips

• •Use this code only when the documentation confirms chlamydial infection but does not specify the anatomical site (such as urethritis, cervicitis, or pelvic inflammatory disease); always query the provider for more specific site information when available
• •Review the medical record for any mention of symptoms, test results, or treatment that might indicate the specific type of chlamydial infection, as more specific codes (A74.0-A74.8) are preferred and provide better clinical detail
