ICD-10 Code B97.19 – Other enterovirus as the cause of diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B97.19 – Other enterovirus as the cause of diseases classified elsewhere
What it is
This code identifies an enterovirus documented as the cause of another condition, rather than a disease on its own. Use it when the record links a non-polio enterovirus to a separate diagnosed illness.
Clinical signs
Clinical features vary; refer to documentation. Enterovirus-related illness may include fever, respiratory symptoms, rash, or neurologic findings, but you should code only the documented causal relationship.
When to use this code
Use B97.19 when the clinician states that an other enterovirus is the cause of a condition classified elsewhere, such as a documented viral syndrome or complication. Pair it with the manifestation or primary diagnosis code for the affected site or illness. If the organism is not specified beyond “enterovirus,” check documentation.
Do not use for
Do not use this code for enteroviral disease coded elsewhere as the main diagnosis, or when a specific enterovirus code is documented instead. Do not assign it without a clear causal link.
Coding tip
Code the underlying condition first and add B97.19 only when the provider explicitly identifies other enterovirus as the cause.
