A56.4

What This Code Means

A bacterial infection of the throat caused by Chlamydia trachomatis, which can cause sore throat, difficulty swallowing, and discharge. This is a sexually transmitted infection that requires antibiotic treatment.

Coding Tips

• •Verify documentation specifies chlamydial infection of the pharynx (throat) rather than other sites like urogenital or rectum, as each has a different code
• •Confirm the organism is Chlamydia trachomatis and document whether this is an initial diagnosis or follow-up visit, as this may affect coding specificity
