A69.1

What This Code Means

Vincent's infection is a serious bacterial infection of the mouth and throat, characterized by painful ulcers, bleeding gums, and tissue destruction. It's caused by a combination of bacteria and typically occurs in people with poor oral hygiene or weakened immune systems.

Coding Tips

• •Verify the specific site of infection (gingiva, pharynx, tonsils, etc.) in the documentation, as this may require additional anatomical specificity codes
• •Distinguish between Vincent's angina (A69.1) and other oral infections; confirm the diagnosis explicitly states 'Vincent's infection' or 'necrotizing ulcerative gingivitis/periodontitis' to ensure accurate code selection
