ICD-10 Code J12.89 – Other viral pneumonia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J12.89 – Other viral pneumonia
What it is
J12.89 identifies pneumonia caused by a virus when the organism is not one of the specific viral causes named elsewhere in ICD-10-CM. Use it for documented viral pneumonia that is otherwise classified as “other.”
Clinical signs
Typical findings include cough, fever, shortness of breath, and imaging consistent with pneumonia. Clinical features vary; refer to documentation for the confirmed viral cause or the provider’s diagnosis.
When to use this code
Use this code when the provider documents viral pneumonia but does not name a more specific viral agent or a different code does not apply. It also fits cases where the chart states “other viral pneumonia” or similar wording. If the record is unclear, check documentation before coding.
Do not use for
Do not use J12.89 for bacterial pneumonia, aspiration pneumonia, or viral respiratory illness without pneumonia. If the pathogen is specifically identified and has its own code, use that code instead.
Coding tip
Code the documented viral pneumonia first, then add any additional organism or manifestation codes only when the record supports them.
