ICD-10 Code A50.45 – Juvenile General Paresis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A50.45 – Juvenile general paresis
What it is
A50.45 identifies juvenile general paresis, a late neurologic manifestation of congenital syphilis. It reflects central nervous system involvement in a child or adolescent, not uncomplicated infection.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include cognitive decline, behavioral changes, neurologic deficits, seizures, or other signs of progressive neurosyphilis.
When to use this code
Use this code when the record clearly documents juvenile general paresis or late congenital syphilitic neurologic disease. You should also use it when the provider links the neurologic findings to congenital syphilis. Check documentation if the chart only says syphilis or neurologic symptoms without that connection.
Do not use for
Do not use this code for uncomplicated syphilis, nonspecific neurocognitive symptoms, or acquired neurosyphilis without congenital origin. If the diagnosis is uncertain, check documentation.
Coding tip
Code A50.45 only when the provider documents both the juvenile paresis diagnosis and its congenital syphilis relationship.
