Other viral diseases (B25-B34)
ICD-10 codes B25-B34 cover a variety of viral diseases beyond common infections, including specific conditions caused by cytomegalovirus, mumps, infectious mononucleosis, viral conjunctivitis, and other uncommon viral infections. These codes provide a detailed way to classify viral illnesses affecting different organs or systems.
For example, B25 codes represent cytomegaloviral diseases, including specialized conditions like cytomegaloviral pneumonitis (B25.0) or cytomegaloviral hepatitis (B25.1). Similarly, B26 codes apply to mumps and its complications such as orchitis and meningitis. The infectious mononucleosis group (B27) distinguishes types caused by Epstein-Barr virus and cytomegalovirus, including related nervous system complications. Codes under B30 specify viral conjunctivitis often due to adenovirus. The range B33 includes diverse viral conditions like viral myocarditis or infections due to retroviruses. Lastly, B34 identifies viral infections of unspecified sites, including adenovirus, enterovirus, coronavirus, and other unspecified viral infections.These codes help clinicians and coders capture specific viral diseases accurately for diagnosis and reporting.
