B00.89 is a billable ICD-10-CM diagnosis code for other herpesviral infection. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 791, 793, 865 through 866, 974 through 976. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 23 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Viral infection.

Questions About B00.89Overview
What is the ICD-10 code for other herpesviral infection?
The ICD-10-CM code for other herpesviral infection is B00.89 (sometimes written as B0089). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is B00.89 (Other forms of herpesviral infections) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other herpesviral infection on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does B00.89 group to?
When other herpesviral infection is the principal diagnosis on an inpatient stay, it groups to MS-DRG 793, 791, 974, 976, 975, 866, 865, with relative weights from 0.7879 to 4.2192 depending on complications. Higher weights mean higher Medicare reimbursement.
Is B00.89 a CC or MCC?
CMS lists B00.89 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 23 closely related codes in its exclusion list.
Can B00.89 be reported with P35.2?
Not as a rule. The Excludes1 note at B00, which applies to B00.89, lists "congenital herpesviral infections (P35.2)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
