Other congenital infectious and parasitic diseases (P37) ICD-10-CM
The P37 code range covers other congenital infectious and parasitic diseases with 9 ICD-10-CM diagnosis codes. 8 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
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.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the P37 range.
Candida
A genus of yeast-like mitosporic Saccharomycetales fungi characterized by producing yeast cells, mycelia, pseudomycelia, and blastophores. It is commonly part of the normal flora of the skin, mouth, intestinal tract, and vagina, but can cause a variety of infections, including CANDIDIASIS; ONYCHOMYCOSIS; VULVOVAGINAL CANDIDIASIS; and CANDIDIASIS, ORAL (THRUSH).
Candidiasis
Infection with a fungus of the genus CANDIDA. It is usually a superficial infection of the moist areas of the body and is generally caused by CANDIDA ALBICANS. (Dorland, 27th ed)
Candidiasis, Chronic Mucocutaneous
A clinical syndrome characterized by development, usually in infancy or childhood, of a chronic, often widespread candidiasis of skin, nails, and mucous membranes. It may be secondary to one of the immunodeficiency syndromes, inherited as an autosomal recessive trait, or associated with defects in cell-mediated immunity, endocrine disorders, dental stomatitis, or malignancy.
Candidiasis, Cutaneous
Candidiasis of the skin manifested as eczema-like lesions of the interdigital spaces, perleche, or chronic paronychia. (Dorland, 27th ed)
Candidiasis, Invasive
An important nosocomial fungal infection with species of the genus CANDIDA, most frequently CANDIDA ALBICANS. Invasive candidiasis occurs when candidiasis goes beyond a superficial infection and manifests as CANDIDEMIA, deep tissue infection, or disseminated disease with deep organ involvement.
Candidiasis, Oral
Infection of the mucous membranes of the mouth by a fungus of the genus CANDIDA. (Dorland, 27th ed)
Candidiasis, Vulvovaginal
Infection of the VULVA and VAGINA with a fungus of the genus CANDIDA.
Listeria
A genus of bacteria which may be found in the feces of animals and man, on vegetation, and in silage. Its species are parasitic on cold-blooded and warm-blooded animals, including man.
Listeriosis
Infections with bacteria of the genus LISTERIA.
About the P37 Code Range
The ICD-10 code section P37 covers various other congenital infectious and parasitic diseases that affect newborns and infants at or shortly after birth. These codes are used to classify infections passed from mother to child during pregnancy or delivery.
This section includes specific codes such as P37.0 for congenital tuberculosis, P37.1 for congenital toxoplasmosis (also known as multisystemic disseminated toxoplasmosis), and P37.2 for neonatal listeriosis, a bacterial infection from Listeria monocytogenes. P37.3 and P37.4 describe congenital malaria cases, including falciparum malaria. The section also includes P37.5 for neonatal candidiasis, referring to fungal infections caused by Candida species, which can affect skin, lungs, and other organs. Additionally, P37.8 covers other specified congenital infections like congenital Lyme disease or infections due to enteroviruses, while P37.9 is used when the congenital infectious or parasitic disease is unspecified. These codes help healthcare professionals and coders accurately document and classify serious neonatal infections important for treatment planning and epidemiological tracking.
