ICD-10 Code A54.9 – Gonococcal infection, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A54.9 – Gonococcal infection, unspecified
What it is
A54.9 identifies a gonococcal infection when the site or specific manifestation is not documented. Use it for confirmed infection caused by Neisseria gonorrhoeae when the record does not specify another code.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings may include urethral, cervical, rectal, or pharyngeal infection, but you should code only what is explicitly recorded.
When to use this code
Use A54.9 when the provider documents gonococcal infection without identifying the anatomic site or a more specific diagnosis. It is also appropriate when the chart confirms gonorrhea but lacks detail needed for a more specific code. Check documentation if complications or site-specific disease are mentioned.
Do not use for
Do not use this code for suspected infection, exposure without confirmed disease, or when a more specific gonococcal code is documented. If another organism or a non-gonococcal STI is named, choose the appropriate code instead.
Coding tip
Look for site, complication, and confirmation in the note before defaulting to A54.9.
