ICD-10 Code A56.2 – Chlamydial infection of genitourinary tract, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A56.2 – Chlamydial infection of genitourinary tract, unspecified
What it is
A56.2 identifies a chlamydial infection involving the genitourinary tract when the site is not further specified. Use it for documented chlamydial disease affecting urinary or reproductive organs without a more precise anatomic description.
Clinical signs
Clinical features vary; refer to documentation. Patients may have urethral or cervical infection, discharge, dysuria, pelvic discomfort, or may be asymptomatic, and the record should confirm chlamydial involvement of the genitourinary tract.
When to use this code
Use A56.2 when the provider documents chlamydial infection of the genitourinary tract but does not specify a more exact site or related complication. It also fits when the note confirms chlamydia and genitourinary involvement, yet the documentation remains nonspecific.
Do not use for
Do not use this code for chlamydial infections at other sites, such as conjunctiva or rectum, or when a more specific genitourinary code is documented. Check documentation if the record names a different condition.
Coding tip
Code only what the provider documents; if the genitourinary site is unclear, A56.2 is appropriate.
