Chlamydial conjunctivitis

This code identifies an ocular infection characterized by inflammation of the conjunctiva caused by Chlamydia trachomatis. It typically presents with mucopurulent discharge, follicular hypertrophy, and often involves both eyes. This condition can range from mild to severe and, if untreated, may lead to corneal scarring.

Assign this code when documentation explicitly states a diagnosis of chlamydial conjunctivitis, often confirmed by laboratory testing for Chlamydia trachomatis. This code is appropriate for both adult inclusion conjunctivitis and ophthalmia neonatorum due to chlamydia. Supporting documentation includes physician notes detailing the clinical presentation, diagnostic test results, and the confirmed chlamydial etiology.

• Differentiate from other forms of conjunctivitis; ensure the chlamydial etiology is clearly documented.
• Consider co-occurring sexually transmitted infections (STIs) and code them appropriately if present and documented.
• For newborns, ensure the documentation specifies ophthalmia neonatorum due to chlamydia to support this specific code.
