ICD-10 Code B97.6 – Parvovirus as the cause of diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B97.6 – Parvovirus as the cause of diseases classified elsewhere
What it is
This code identifies parvovirus as the infectious cause of another condition, rather than the primary diagnosis. Use it when documentation links parvovirus to a separate disease process.
Clinical signs
Clinical features vary; refer to documentation. Parvovirus infection may be associated with rash, joint symptoms, or findings of a related illness, but you should code only what is clearly documented.
When to use this code
Use B97.6 when the record states parvovirus is the cause of a condition classified elsewhere, such as an associated disorder or complication. Pair it with the manifestation or principal diagnosis that reflects the patient’s current problem. If the provider does not identify parvovirus as the cause, check documentation.
Do not use for
Do not use this code for a primary parvovirus infection without a linked secondary condition. Do not assign it when another organism or cause is documented instead.
Coding tip
Always code the underlying manifestation first and add B97.6 only when the provider clearly documents parvovirus as the cause.
