ICD-10 Code J00 – Acute nasopharyngitis [common cold] (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J00 – Acute nasopharyngitis [common cold]
What it is
J00 identifies an acute viral upper respiratory infection commonly called the common cold. Use it when documentation states acute nasopharyngitis, with or without mention of a cold.
Clinical signs
Typical findings include runny nose, nasal congestion, sneezing, sore throat, and mild cough. Fever may occur, especially in children; clinical features vary, so refer to documentation.
When to use this code
Use J00 when the provider documents acute nasopharyngitis or common cold as the diagnosis. It is appropriate for uncomplicated, self-limited upper respiratory illness without a more specific coded condition. If the note only says “URI,” check documentation for the exact diagnosis.
Do not use for
Do not use J00 for influenza, strep throat, sinusitis, bronchitis, or pneumonia. If the record supports a different respiratory diagnosis, code that condition instead.
Coding tip
Code J00 only when the provider specifically documents common cold or acute nasopharyngitis; otherwise, check documentation for a more precise diagnosis.
