ICD-10 Code A50.05 – Early congenital syphilitic rhinitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A50.05 – Early congenital syphilitic rhinitis
What it is
A50.05 identifies early congenital syphilitic rhinitis, a syphilis infection present in an infant that affects the nasal mucosa. It is used when documentation specifically links the rhinitis to congenital syphilis.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe nasal inflammation, discharge, and possible nasal obstruction in affected newborns or infants.
When to use this code
Use this code when the provider documents early congenital syphilitic rhinitis or congenital syphilis with nasal involvement. It may also apply when the record clearly states rhinitis due to congenital syphilis. Check documentation if the nasal findings are present but the cause is not specified.
Do not use for
Do not use this code for routine infectious rhinitis, allergic rhinitis, or nonspecific nasal congestion. If congenital syphilis is not documented, choose a more appropriate diagnosis.
Coding tip
Confirm that the record explicitly connects the rhinitis to congenital syphilis before assigning A50.05.
