Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Piry virus disease
- Vesicular stomatitis virus disease [Indiana fever]
Other codes that can never be billed with A93.8
These codes carry an Excludes1 note pointing at A93.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A93.8 alone.
- B08Other viral infections characterized by skin and mucous membrane lesions, not elsewhere classified
Risk adjustment
A93.8 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
A93.8 is named in 4 Medicare coverage policies — 4 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
