Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Kaposi's varicelliform eruption

Excludes1 inherited from the categories above B00.0

These are not written on B00.0, but they bind it: a note on a category applies to every code beneath it. Billing B00.0 with anything listed here is a denial.

Written on B00 — Herpesviral [herpes simplex] infections

congenital herpesviral infections (P35.2)

Excludes2 inherited from the categories above B00.0

Also inherited, and the opposite of Excludes1: these conditions are not part of B00.0, but a patient can have both, so you may code both.

Written on B00 — Herpesviral [herpes simplex] infections

anogenital herpesviral infection (A60.-)
gammaherpesviral mononucleosis (B27.0-)
herpangina (B08.5)

Risk adjustment

B00.0 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

B00.0 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.
