    ICD-10-CM Code For Erysipeloid: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group A26 includes infections caused by Erysipelothrix rhusiopathiae, such as localized cutaneous erysipeloid and more invasive forms that can involve deeper soft tissues or systemic spread. These ICD-10-CM diagnosis codes are used to document clinical scenarios including acute skin infections after animal exposure, identification of infection extent, and any complications or systemic involvement. Accurate coding within the ICD-10-CM A26 group supports proper claim adjudication and complete clinical documentation for appropriate reimbursement.

    ICD-10-CM A26: Erysipeloid Overview

    Erysipeloid diagnoses represent infections caused by the bacterium Erysipelothrix rhusiopathiae, typically affecting the skin and sometimes leading to deeper tissue involvement. These conditions primarily target the integumentary and soft tissue systems, often following occupational or animal-related exposures. Accurate coding matters for correct classification of zoonotic bacterial infections and can affect reimbursement and public health reporting.

    When to Use

    Use a code from this group when a clinician documents erysipeloid or infection due to Erysipelothrix rhusiopathiae, including specified localized skin infection or documented systemic involvement. Select codes that reflect the documented site, severity, and any complications to ensure accurate classification.

    Typical Clinical Scenarios

    • An adult fisherman presents to the emergency department with a rapidly expanding, painful, purplish cellulitis on the dorsal hand after handling raw fish; he reports a puncture scratch sustained while gutting fish 48 hours earlier and has fever and localized lymphangitic streaking. A diagnosis from this group is assigned because the clinical picture and marine exposure are consistent with an acute cutaneous infection due to a zoonotic organism acquired from fish handling. Typical codes: A26.0
    • An outpatient seen in dermatology for a persistent, indurated plaque at the site of a prior hand injury three weeks earlier that has slowly enlarged despite topical care; there is minimal systemic illness but chronic localized skin involvement consistent with a prolonged cutaneous infection following animal exposure. A diagnosis from this group is assigned to classify a nonacute or subacute cutaneous zoonotic infection requiring follow-up and possible targeted therapy. Typical codes: A26.8, A26.9
    • A hospitalized elderly patient with diabetes presents with bacteremia and secondary cellulitis after a wound contaminated by animal tissue; the patient has systemic signs of infection and complications related to impaired host defenses, prompting inpatient management. A diagnosis from this group is assigned when a zoonotic bacterial species is implicated as the primary infecting agent contributing to the systemic infection and soft tissue involvement. Typical codes: A26.7
