2025 ICD-10-CM code A50

Congenital syphilis is a condition passed from a pregnant person to their fetus during pregnancy or childbirth.

Use additional code to identify resistance to antimicrobial drugs (Z16.-). Certain localized infections are excluded (see body system-related chapters). Carrier or suspected carrier of infectious disease (Z22.-) is also excluded. Infectious and parasitic diseases complicating pregnancy, childbirth and the puerperium (O98.-) and specific to the perinatal period (P35-P39) are excluded. Influenza and other acute respiratory infections (J00-J22) are excluded as well.

Medical necessity for congenital syphilis treatment is established by the presence of the infection in the infant, confirmed through diagnostic testing. The severity of the infection, the presence of symptoms, and the potential for long-term complications all contribute to the medical necessity justification.

Physicians are responsible for diagnosing and managing congenital syphilis. This includes testing pregnant women for syphilis, providing appropriate antibiotic treatment to infected mothers and newborns, and conducting follow-up assessments to monitor treatment effectiveness and potential long-term complications in infants.

In simple words: Congenital syphilis is a disease that babies can get from their mothers during pregnancy or birth. It's caused by bacteria that can cause serious health problems if not treated. Sometimes, babies with congenital syphilis don't show any symptoms at birth, but they can develop severe issues later if they don't receive treatment. These problems can include developmental delays, seizures, or even death. It's crucial for pregnant women to get tested for syphilis to protect their babies.

Congenital syphilis, caused by the bacterium Treponema pallidum, occurs when a pregnant person with syphilis transmits the infection to their fetus through the placenta or during delivery. This can result in a range of severe health problems for the infant, including stillbirth, death soon after birth, and various physical and developmental issues if left untreated. Early congenital syphilis typically manifests within the first three months of life, while late congenital syphilis appears after two years of age. Some infants may remain asymptomatic throughout their lives, even with the infection.

Example 1: A pregnant woman tests positive for syphilis during her first prenatal visit. She receives penicillin treatment, and her newborn is closely monitored for signs of congenital syphilis. The newborn also receives antibiotic treatment as a precaution., A newborn exhibits symptoms of congenital syphilis, including a runny nose, rash, and an enlarged liver and spleen. Diagnostic testing confirms the infection, and the infant receives a course of penicillin., A child presents with symptoms of late congenital syphilis, such as bone deformities, hearing loss, and Hutchinson's teeth.Serologic testing and physical examination confirm the diagnosis, and the child undergoes treatment and long-term monitoring for complications.

Documentation for congenital syphilis should include maternal syphilis testing results, infant physical examination findings, serologic tests performed on the infant, imaging studies (if conducted), treatment administered, and follow-up care plans.
