ICD-10 Code A71 – Trachoma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A71 – Trachoma
What it is
Trachoma is a chronic eye infection caused by Chlamydia trachomatis. It can lead to eyelid scarring, inward-turning lashes, and vision loss if untreated.
Clinical signs
Common findings include conjunctival inflammation, follicles on the inner eyelid, scarring, and corneal irritation. Clinical features vary; refer to documentation.
When to use this code
Use A71 when the provider documents trachoma as the diagnosis, including active disease or chronic sequelae tied to trachomatous infection. Use it for confirmed clinical documentation, not for nonspecific conjunctivitis or undifferentiated eye irritation. Check documentation if the record does not clearly state trachoma.
Do not use for
Do not use this code for ordinary bacterial or viral conjunctivitis, keratitis, or eyelid disorders without documented trachoma. If the diagnosis is uncertain, check documentation.
Coding tip
Code A71 only when the record clearly names trachoma or trachomatous disease.
