    ICD-10-CM Code For Yellow Fever: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group A95 includes diagnoses for Yellow fever, an arthropod-borne viral infection that ranges from self-limited febrile illness to severe hemorrhagic disease with hepatic and renal involvement. These ICD-10-CM diagnosis codes are used to document confirmed or suspected Yellow fever infections, capturing disease severity, organ involvement, and clinical complexity such as hemorrhagic complications or sequelae. Accurate coding within the ICD-10-CM A95 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM A95: Yellow Fever Overview

    The diagnoses in this group represent Yellow fever, an acute viral disease transmitted by infected mosquitoes that can involve systemic febrile illness and sometimes hemorrhagic manifestations. These conditions target the infectious disease and hepatobiliary systems, with potential for severe multi-organ involvement. Accurate coding matters for clinical communication and reimbursement because it captures disease severity, complications, and travel-related exposures that affect claim adjudication.

    Assign a code from this group when a patient has a confirmed or clinically diagnosed Yellow fever infection, including cases with documented hemorrhagic or hepatic complications. Use these codes to reflect current clinical findings, severity, and any complications relevant to the episode of care.

    Typical Clinical Scenarios

    • A traveler returning from a country with active yellow fever transmission presents to the emergency department with high fever, severe headache, myalgias, and jaundice. Laboratory tests show elevated liver enzymes and thrombocytopenia, and the clinician documents an acute systemic viral illness consistent with yellow fever after ruling out other causes; this acute presentation prompts assignment of the specific yellow fever diagnosis. Typical codes: A95.0, A95.1
    • An adult patient in an outpatient tropical medicine clinic is evaluated after recent travel and reports a febrile illness with a short course of gastrointestinal symptoms, conjunctival injection, and mild hepatic enzyme elevation; the clinician documents a confirmed or suspected uncomplicated yellow fever infection as the primary diagnosis for ambulatory care and public health reporting. Typical codes: A95.0, A95.9
    • A hospitalized patient develops severe hemorrhagic manifestations (gastrointestinal bleeding, coagulopathy) and multiorgan dysfunction following an acute febrile illness after travel to an endemic area; the treating team documents yellow fever as the underlying cause of the hemorrhagic complication and codes it as the principal infectious diagnosis contributing to the acute morbid state. Typical codes: A95.1, A95.0}
