Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the A26 range.
Erysipeloid
An infection caused by Erysipelothrix rhusiopathiae that is almost wholly restricted to persons who in their occupation handle infected fish, shellfish, poultry, or meat. Three forms of this condition exist: a mild localized form manifested by local swelling and redness of the skin; a diffuse form that might present with fever; and a rare systemic form associated with endocarditis.
Erysipelothrix
A genus of gram-positive, facultatively anaerobic, rod-shaped bacteria that has a tendency to form long filaments. Its organisms are widely distributed in nature and are found in MAMMALS; BIRDS; and FISHES. Erysipelothrix may appear gram-negative because they decolorize easily.
Erysipelothrix Infections
Infections with bacteria of the genus ERYSIPELOTHRIX.
About the A26 Code Range
ICD-10 code A26 covers erysipeloid, a bacterial infection primarily caused by Erysipelothrix rhusiopathiae. These codes classify different types and severities of the infection, ranging from localized skin involvement to severe systemic illness.
The A26.0 code is used for cutaneous erysipeloid, which is a localized skin infection often referred to simply as erysipeloid or infection by Erysipelothrix. For more severe infections, A26.7 identifies eryspelothrix sepsis, describing bloodstream infections (sepsis) caused by the same bacteria. Other manifestations, including infections causing joint inflammation (polyarthritis) or heart lining infection (endocarditis), fall under A26.8. When a specific type is not detailed, A26.9 is used for unspecified erysipeloid. Understanding these distinctions helps medical coders correctly assign the ICD-10 code for erysipeloid based on clinical presentation, aiding accurate medical record documentation and treatment tracking.
