ICD-10 Code A56.19 – Other chlamydial genitourinary infection (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A56.19 – Other chlamydial genitourinary infection
What it is
A56.19 identifies a chlamydial infection of the genitourinary tract that is not classified elsewhere. Use it when documentation specifies an “other” chlamydial genital or urinary infection.
Clinical signs
Clinical features vary; refer to documentation. You may see urethral, cervical, or other genitourinary inflammation associated with Chlamydia, but the record should support the site and organism.
When to use this code
Use this code when the provider documents a chlamydial genitourinary infection and does not name a more specific category. It may fit cases involving genital or urinary tract involvement that are not otherwise classified. If the site or type is unclear, check documentation before coding.
Do not use for
Do not use A56.19 for chlamydial infections with a more specific ICD-10-CM code, or for infections outside the genitourinary tract. Check documentation if the record only says “chlamydia” without a genitourinary site.
Coding tip
Confirm the provider’s exact wording and site before assigning A56.19, because more specific chlamydial codes may apply.
