Chlamydial infection, unspecified

This code signifies a chlamydial infection where the specific site or type of infection is not documented. It indicates the presence of Chlamydia trachomatis or other Chlamydia species without further anatomical or etiological detail. This diagnosis is typically made based on laboratory confirmation of Chlamydia.

This code is appropriate when a patient has a confirmed chlamydial infection, but the medical record lacks specificity regarding the affected body system (e.g., genitourinary, ocular, respiratory) or the specific Chlamydia species. It should be used when documentation only states "chlamydial infection" without further elaboration.

• Avoid using this code if a more specific chlamydial infection code (e.g., A74.0-A74.8) can be assigned based on documentation.
• Query the provider for clarification on the site of infection if only "chlamydial infection" is documented to allow for more specific coding.
• Always sequence this code as a primary diagnosis when it is the reason for the encounter, unless another condition is the primary reason and the chlamydial infection is a co-morbidity.
