ICD-10 Code A50.06 – Early cutaneous congenital syphilis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A50.06 – Early cutaneous congenital syphilis
What it is
Early cutaneous congenital syphilis is a newborn or infant manifestation of congenital syphilis with skin involvement. It indicates early infection acquired from the mother before birth.
Clinical signs
Findings may include rash, desquamation, bullous lesions, or other skin changes consistent with congenital syphilis. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents early congenital syphilis with cutaneous findings. The diagnosis should identify skin involvement as part of the congenital infection, not just a nonspecific neonatal rash.
Choose it when the clinician links the rash or skin lesions to congenital syphilis. If the chart only says “possible” syphilis or gives no skin detail, check documentation before coding.
Do not use for
Do not use this code for acquired syphilis, late congenital syphilis, or a skin rash without confirmed congenital syphilis. Check documentation when the cause of the eruption is unclear.
Coding tip
Verify that congenital syphilis and cutaneous involvement are both documented before assigning A50.06.
