ICD-10 Code A69.1 – Other Vincent’s infections (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A69.1 – Other Vincent’s infections
What it is
A69.1 identifies other infections caused by Vincent organisms, a group of spirochetal infections not classified elsewhere. Use it for documented Vincent infection when the record specifies this diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Records may describe oral, gingival, or ulcerative lesions associated with Vincent infection, but you should code only what is clearly stated.
When to use this code
Use A69.1 when the clinician documents other Vincent’s infections and the case is not better described by a more specific code. It is appropriate for confirmed or assessed Vincent infection in the chart. Check documentation if the note uses older terms or unclear wording.
Do not use for
Do not use this code for nonspecific oral infection, gingivitis, or periodontal disease unless Vincent infection is explicitly documented. If the diagnosis is uncertain or another condition is named, choose the more accurate code.
Coding tip
Code the exact documented infection term and avoid assuming Vincent disease from symptoms alone.
