ICD-10 Code A50.2 – Early congenital syphilis, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A50.2 – Early congenital syphilis, unspecified
What it is
A50.2 identifies early congenital syphilis when the infection is present in an infant or newborn but the record does not specify the exact early manifestation. Use it when documentation confirms congenital syphilis, yet details are limited.
Clinical signs
Clinical features vary; refer to documentation. Early congenital syphilis may present with findings such as rash, nasal discharge, hepatosplenomegaly, or other signs of neonatal infection, but you should code only what is documented.
When to use this code
Use A50.2 when the provider documents early congenital syphilis without naming a more specific early form. It is appropriate for newborn or infant records describing congenital infection, especially when the chart lacks detail on the specific organ involvement or stage. Check documentation if the case is unclear.
Do not use for
Do not use this code for late congenital syphilis or for acquired syphilis in an older child or adult. If the record specifies another congenital syphilis subtype, code that more specific diagnosis instead.
Coding tip
Code the highest level of specificity documented, and query the provider if “congenital syphilis” is stated without an early versus late designation.
