Chlamydial infection of anus and rectum

This code signifies a chlamydial infection specifically affecting the anal and rectal regions. It indicates the presence of Chlamydia trachomatis in these anatomical sites, often manifesting as proctitis or other inflammatory conditions.

Use this code when documentation confirms a diagnosis of chlamydial proctitis or other chlamydial infection localized to the anus and rectum. This typically arises from sexual contact and may be asymptomatic or present with symptoms like rectal pain, discharge, or tenesmus.

• Ensure the documentation explicitly states "chlamydial" and specifies the "anus" and/or "rectum" as the site of infection.
• Do not use this code for chlamydial infections of other genitourinary sites; specific codes exist for those locations.
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it is a co-existing condition.
