Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Cancrum oris
- Fusospirochetal gangrene
- Noma
- Stomatitis gangrenosa
Other codes that can never be billed with A69.0
These codes carry an Excludes1 note pointing at A69.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A69.0 alone.
- K12Stomatitis and related lesions
Risk adjustment
A69.0 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.
Medicare coverage
A69.0 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
- A54111Billing and Coding: Speech Language Pathology (SLP) Services: Communication Disorders
