ICD-10 Code A71.1 – Active stage of trachoma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A71.1 – Active stage of trachoma
What it is
A71.1 identifies the active inflammatory phase of trachoma, a contagious eye infection caused by Chlamydia trachomatis. Use it when documentation states active trachoma rather than a healed or scarred stage.
Clinical signs
Findings may include conjunctival redness, irritation, discharge, follicles, and eyelid inflammation. Clinical features vary; refer to documentation, especially when the record specifies active disease or associated corneal involvement.
When to use this code
Use A71.1 when the provider documents active trachoma, active follicular conjunctivitis due to trachoma, or ongoing infection requiring diagnosis coding. It also fits cases where the chart clearly distinguishes active disease from residual scarring or blindness. Check documentation if the stage is not specified.
Do not use for
Do not use this code for healed trachoma, trachomatous scarring, or visual loss without active infection. If the note describes another cause of conjunctivitis or eye irritation, code the documented condition instead.
Coding tip
Confirm the stage in the record; “trachoma” alone is not enough when active disease is not clearly documented.
