A26.9 ICD-10-CM Code: Erysipeloid, unspecified

A26.9 is the ICD-10-CM diagnosis code for erysipeloid, unspecified. Erysipeloid is a skin infection caused by bacteria, typically occurring on the hands or fingers, characterized by redness, swelling, and sometimes blistering. This code is used when the specific type or location of erysipeloid is not documented. A26.9 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering certain zoonotic bacterial diseases (a20-a28).

A26.9 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

Use this unspecified code only when the documentation does not indicate the specific site (such as finger, hand, or other location) of the erysipeloid infection.
