ICD-10 Code A50.01 – Early congenital syphilitic oculopathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A50.01 – Early congenital syphilitic oculopathy
What it is
This code identifies eye involvement from congenital syphilis appearing early in life. Use it when documentation specifies congenital syphilitic disease affecting the eyes.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe ocular inflammation or other eye findings linked to congenital syphilis, but the exact presentation may differ by patient.
When to use this code
Use A50.01 when the provider documents early congenital syphilitic oculopathy, congenital syphilis with ocular involvement, or a similar specific eye manifestation. It is appropriate only when the record clearly links the eye condition to congenital syphilis. If the note is nonspecific, check documentation before coding.
Do not use for
Do not use this code for acquired syphilis, isolated eye disease without congenital syphilis, or unspecified congenital syphilis. If the record does not confirm ocular involvement, choose a different, more accurate code.
Coding tip
Code only when the congenital syphilis diagnosis and the eye involvement are both documented together.
