B00 — Herpesviral [herpes simplex] infections
Is B00 billable?
No — B00 is a non-billable header code. B00 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 15 billable codes beneath B00.

Excludes1 — never code together
The conditions below can never be reported together with B00 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- congenital herpesviral infections (P35.2)
Excludes2 — not included here
The conditions below are not part of B00, but a patient may have both at the same time. When documentation supports it, B00 and the excluded code may both be reported.
Use additional code — inherited from Chapter 1
Report an additional code alongside B00 to fully describe the condition. B00 is sequenced first.
- code to identify resistance to antimicrobial drugs (Z16.-)
Excludes2 — not included here — inherited from Chapter 1
The conditions below are not part of B00, but a patient may have both at the same time. When documentation supports it, B00 and the excluded code may both be reported.
- carrier or suspected carrier of infectious disease (Z22.-)
- certain localized infections - see body system-related chapters
- infectious and parasitic diseases complicating pregnancy, childbirth and the puerperium (O98.-)
- infectious and parasitic diseases specific to the perinatal period (P35-P39)
- influenza and other acute respiratory infections (J00-J22)
