ICD-10 Code A71.9 – Trachoma, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A71.9 – Trachoma, unspecified
What it is
A71.9 identifies trachoma when the record does not specify a stage or form. It is used for this chronic eye infection caused by Chlamydia trachomatis when documentation is limited.
Clinical signs
Clinical features vary; refer to documentation. Commonly described findings include chronic conjunctival inflammation, irritation, discharge, and eyelid scarring in advanced disease.
When to use this code
Use A71.9 when the provider documents trachoma but does not name the stage, severity, or specific manifestation. It also fits when the note simply says “trachoma” without further detail. If the record identifies a more specific trachoma type, code that instead.
Do not use for
Do not use this code for other conjunctival infections, nonspecific eye irritation, or trachoma with a documented subtype. Check documentation if the chart names a more precise diagnosis.
Coding tip
Code the most specific trachoma diagnosis available; if the provider does not specify more, A71.9 is appropriate.
