ICD-10 Code B00.8 – Other forms of herpesviral infections (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B00.8 – Other forms of herpesviral infections
What it is
B00.8 is used for herpesviral infections that do not fit a more specific herpes code. It captures documented herpesvirus disease when the record names an atypical or unspecified nonclassic presentation.
Clinical signs
Clinical features vary; refer to documentation. Findings may include vesicular lesions, pain, or other herpes-related manifestations, depending on the site and virus type.
When to use this code
Use B00.8 when the clinician documents a herpesviral infection, but the chart does not support a more specific herpes code. It is appropriate for other specified herpes presentations that are not classified elsewhere. Check documentation if the site, virus, or complication is unclear.
Do not use for
Do not use this code for herpes simplex with a more specific site or complication code, or for conditions not documented as herpesviral infection. If the record is vague, check documentation before assigning B00.8.
Coding tip
Code the most specific herpes diagnosis available; use B00.8 only when no better-defined herpes code is supported.
