Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Herpes simplex facialis
- Herpes simplex labialis
- Herpes simplex otitis externa
- Vesicular dermatitis of ear
- Vesicular dermatitis of lip
Other codes that can never be billed with B00.1
These codes carry an Excludes1 note pointing at B00.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading B00.1 alone.
- H62.4Otitis externa in other diseases classified elsewhere
Risk adjustment
B00.1 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.
Medicare coverage
B00.1 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.
