Coccidioidomycosis
Infection with a fungus of the genus COCCIDIOIDES, endemic to the SOUTHWESTERN UNITED STATES. It is sometimes called valley fever but should not be confused with RIFT VALLEY FEVER. Infection is caused by inhalation of airborne, fungal particles known as arthroconidia, a form of FUNGAL SPORES. A primary form is an acute, benign, self-limited respiratory infection. A secondary form is a virulent, severe, chronic, progressive granulomatous disease with systemic involvement. It can be detected by use of COCCIDIOIDIN.
About the B38 Code Range
Coccidioidomycosis, also called valley fever, is a fungal infection caused by inhaling airborne fungal particles.
The lung codes distinguish acute infection (B38.0), chronic infection (B38.1), and infection without a specified course (B38.2). Other codes identify skin involvement (B38.3), meningitis involving the central nervous system (B38.4), and infection spread through the body (B38.7).
B38.8 groups other forms, with subdivisions for prostate involvement (B38.81) and other forms (B38.89). B38.9 identifies coccidioidomycosis without a specified form.
