ICD-10 Code A50.09 – Other early congenital syphilis, symptomatic (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A50.09 – Other early congenital syphilis, symptomatic
What it is
A50.09 identifies early congenital syphilis with symptoms that do not fit a more specific early congenital syphilis code. Use it for infants or newborns with clinically evident infection acquired before birth.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include rash, nasal discharge, hepatosplenomegaly, jaundice, anemia, or skeletal abnormalities consistent with congenital syphilis.
When to use this code
Use this code when the record documents symptomatic early congenital syphilis and the provider does not name a more specific subtype. It may apply during the neonatal period or early infancy when signs are present and congenital infection is confirmed or strongly documented.
Code it only when the chart supports a symptomatic congenital presentation, not mere exposure or maternal history alone. Check documentation if the note is vague, incomplete, or uses an unspecified syphilis term.
Do not use for
Do not use this code for late congenital syphilis, asymptomatic congenital infection, or acquired syphilis in the patient. If the documentation points to another congenital syphilis type, code that specific diagnosis instead.
Coding tip
Look for the words “symptomatic” and “early congenital” in the provider note before assigning A50.09.
