ICD-10 Code B34.4 – Papovavirus infection, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B34.4 – Papovavirus infection, unspecified
What it is
B34.4 identifies a papovavirus infection that is not further specified in the record. Use it when the provider documents a papovavirus infection but does not name a particular virus or site.
Clinical signs
Clinical features vary; refer to documentation. Papovavirus infections may be recorded with viral illness signs, but this code itself does not define a specific syndrome or organ involvement.
When to use this code
Use B34.4 when the diagnosis is clearly documented as papovavirus infection and no more specific code is available. It is appropriate when the chart lacks details needed to assign a more exact viral diagnosis. Check documentation if the organism, site, or clinical manifestation is better described elsewhere.
Do not use for
Do not use this code for a more specific papovavirus-related diagnosis when one is documented. Do not assign it for symptoms alone or when the record supports another confirmed viral condition.
Coding tip
Before assigning B34.4, confirm that the provider actually documents papovavirus infection and that no more specific code applies.
