ICD-10 Code A26.9 – Erysipeloid, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A26.9 – Erysipeloid, unspecified
What it is
A26.9 identifies erysipeloid when the record does not specify the site or a more exact form. It is used for this localized bacterial skin infection when documentation is limited.
Clinical signs
Clinical features vary; refer to documentation. Typical descriptions include a localized, painful, reddish-purple skin lesion, often on the hands or fingers, with swelling and tenderness.
When to use this code
Use A26.9 when the clinician documents erysipeloid but does not identify whether it is cutaneous, septic, or another specified form. It also fits when the note confirms erysipeloid and no additional detail is available. Check documentation if the site or complication is stated.
Do not use for
Do not use this code if the record specifies a different form of erysipeloid or another diagnosis entirely. If the infection is documented as a different bacterial skin condition, code that condition instead.
Coding tip
Assign the unspecified code only after confirming the note lacks a more specific erysipeloid description.
