ICD-10 Code A54.31 – Gonococcal conjunctivitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A54.31 – Gonococcal conjunctivitis
What it is
A54.31 identifies conjunctivitis caused by Neisseria gonorrhoeae. Use it when the chart documents gonococcal infection of the conjunctiva, including neonatal or adult cases.
Clinical signs
Typical findings include red, swollen eyes with purulent discharge and marked conjunctival inflammation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider diagnoses gonococcal conjunctivitis or records conjunctival infection due to gonorrhea. It may also apply when the note clearly links eye involvement to gonococcal disease. If the record only says conjunctivitis without an organism, check documentation.
Do not use for
Do not use A54.31 for nonspecific conjunctivitis, viral conjunctivitis, or other bacterial eye infections without gonococcal documentation. Check documentation if the organism is not confirmed.
Coding tip
Code the documented organism and site together; do not assume gonococcal eye disease from discharge alone.
