B00.81 — Herpesviral hepatitis
B00.81 is a billable, specific ICD-10-CM code for herpesviral hepatitis. It is valid for submission on a claim.
Excludes1 inherited from the categories above B00.81
These are not written on B00.81, but they bind it: a note on a category applies to every code beneath it. Billing B00.81 with anything listed here is a denial.
Excludes2 inherited from the categories above B00.81
Also inherited, and the opposite of Excludes1: these conditions are not part of B00.81, but a patient can have both, so you may code both.
Other codes that can never be billed with B00.81
These codes carry an Excludes1 note pointing at B00.81. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading B00.81 alone.

Risk adjustment
B00.81 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.
How B00.81 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to B00.81.
