A69.1 — Other Vincent's infections
A69.1 is a billable, specific ICD-10-CM code for other vincent's infections. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Fusospirochetal pharyngitis
- Necrotizing ulcerative (acute) gingivitis
- Necrotizing ulcerative (acute) gingivostomatitis
- Spirochetal stomatitis
- Trench mouth
- Vincent's angina
- Vincent's gingivitis
Other codes that can never be billed with A69.1
These codes carry an Excludes1 note pointing at A69.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A69.1 alone.
Risk adjustment
A69.1 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
