ICD-10 Code A50.39 – Other late congenital syphilitic oculopathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A50.39 – Other late congenital syphilitic oculopathy
What it is
This code identifies late eye disease caused by congenital syphilis. Use it when the record documents an ocular complication from congenital infection that does not fit a more specific late congenital syphilitic eye code.
Clinical signs
Findings may include chronic visual impairment, inflammation, scarring, or other eye abnormalities linked to congenital syphilis. Clinical features vary; refer to documentation.
When to use this code
Use A50.39 when the provider documents a late congenital syphilitic eye disorder and specifies “other” or an unspecified ocular manifestation not captured elsewhere. Code it only when the condition is attributed to congenital syphilis, not acquired infection. Check documentation if the eye finding is described without a congenital syphilis link.
Do not use for
Do not use this code for acquired syphilis, nonspecific visual complaints, or eye disease with no documented congenital syphilis cause. If a more specific late congenital syphilitic oculopathy code applies, use that instead.
Coding tip
Confirm both the congenital syphilis history and the ocular manifestation before assigning A50.39.
