Early congenital syphilitic rhinitis. This condition is a manifestation of early congenital syphilis affecting the mucous membranes of the nose and nasal passages in newborns.

Use additional code to identify resistance to antimicrobial drugs (Z16.-).

Medical necessity is established by the presence of clinical signs and symptoms of early congenital syphilitic rhinitis in a newborn or infant with confirmed congenital syphilis.

A newborn with this condition may experience sneezing and nasal discharge, potentially tinged with blood and mucus. Diagnosis involves patient history, examination of nostrils (which may show ulceration and yellowish-green scabs), and laboratory tests like serologic tests for syphilis and dark-field microscopy. Treatment includes topical applications and antibiotics.

In simple words: Early congenital syphilitic rhinitis is a nose problem in newborns caused by syphilis passed from the mother. It causes a stuffy nose, sometimes with bloody mucus.

Early congenital syphilitic rhinitis is a manifestation of early congenital syphilis (symptoms typically present less than 2 years after birth) affecting the nose and nasal passages. Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum, which can be transmitted from mother to baby during pregnancy or delivery.

Example 1: A newborn presents with sneezing, nasal discharge with blood and mucus, and a skin rash. The mother's history reveals untreated syphilis. Serologic tests confirm congenital syphilis, and the nasal discharge is diagnosed as early congenital syphilitic rhinitis., An infant less than two years old exhibits persistent nasal congestion and a "saddle nose" deformity.Upon examination and laboratory testing, early congenital syphilitic rhinitis is diagnosed as a consequence ofcongenital syphilis., A newborn, whose mother has a history of syphilis, is examined shortly after birth. While asymptomatic, lab tests reveal congenital syphilis.Prophylactic treatment is initiated to prevent the development of symptoms, including rhinitis.

Documentation should include the mother's history of syphilis, the infant's symptoms (sneezing, nasal discharge characteristics, nasal examination findings), laboratory results (serologic tests, dark-field microscopy), and treatment details.
