Inclusion conjunctivitis

This code identifies conjunctivitis caused by Chlamydia trachomatis, specifically serovars D through K. It presents as an acute or chronic inflammation of the conjunctiva, often with mucopurulent discharge, follicular hypertrophy, and sometimes corneal involvement. This condition is typically sexually transmitted in adults and perinatally acquired in neonates.

Assign this code when documentation confirms a diagnosis of conjunctivitis due to Chlamydia. This often involves laboratory confirmation (e.g., PCR, culture) or a strong clinical suspicion in the context of a chlamydial infection elsewhere in the body. It is commonly seen in neonates born to mothers with chlamydial infections and in sexually active adults.

• Differentiate from trachoma (Chlamydia serovars A, B, Ba, C), which has a distinct code.
• Always look for documentation of the causative organism (Chlamydia trachomatis) to support this specific diagnosis.
• Consider co-occurring sexually transmitted infections in adults and code them appropriately.
