Infections specific to the perinatal period (P35-P39)

ICD-10 codes P35-P39 cover infections that specifically affect newborns during the perinatal period, that is, shortly before or after birth. These codes identify viral, bacterial, parasitic, fungal, and other infections present at birth or acquired in the early neonatal phase.

This range includes P35 for congenital viral diseases like congenital rubella syndrome (P35.0), cytomegalovirus infection (P35.1), and congenital herpesviral infections (P35.2). Other distinct viral infections coded here are congenital viral hepatitis (P35.3) and congenital Zika virus disease (P35.4). Codes under P36 designate bacterial sepsis of the newborn, including infections caused by group B streptococcus (P36.0), Staphylococcus aureus (P36.2), Escherichia coli (P36.4), and other bacteria. P37 addresses other congenital infectious and parasitic diseases like tuberculosis (P37.0), toxoplasmosis (P37.1), listeriosis (P37.2), and congenital malaria (P37.3, P37.4). Omphalitis of the newborn, an infection of the umbilical stump, is found under P38. The P39 codes cover various other infections specific to the perinatal period such as neonatal mastitis (P39.0), conjunctivitis and dacryocystitis (P39.1), urinary tract infections (P39.3), and skin infections (P39.4), as well as other specified or unspecified perinatal infections.

These codes help healthcare providers and medical coders accurately capture the specific types of infections affecting newborns around birth, including terms like rubella pneumonia, neonatal sepsis due to Streptococcus agalactiae, congenital toxoplasmosis, or neonatal staphylococcal infection. Using these codes precisely supports effective diagnosis, treatment, and reporting of infections unique to the perinatal period.

Instructional Notations

Inclusion Terms

These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Infections acquired in utero, during birth via the umbilicus, or during the first 28 days after birth

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
