ICD-10 Code A26 – Erysipeloid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A26 – Erysipeloid
What it is
A26 identifies erysipeloid, a localized bacterial skin infection usually linked to exposure to infected animals or animal products. It most often affects the hands or fingers after a skin break.
Clinical signs
Typical findings include a painful, swollen, red to violaceous lesion with sharply defined borders, often on the hands. Clinical features vary; refer to documentation.
When to use this code
Use A26 when the provider documents erysipeloid by name or clearly describes the condition as a localized infection consistent with that diagnosis. Code it for confirmed or treated cases tied to the documented clinical picture. Check documentation if the record only notes nonspecific cellulitis or dermatitis.
Do not use for
Do not use A26 for ordinary erysipelas, cellulitis, or other skin infections unless erysipeloid is specifically documented. Do not assume the code from animal exposure alone.
Coding tip
Verify the exact diagnosis wording and any documented exposure source before assigning A26.
