ICD-10 Code J32.9 – Chronic Sinusitis, Unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J32.9 – Chronic sinusitis, unspecified
What it is
J32.9 identifies chronic inflammation of the paranasal sinuses when the specific sinus or sinus type is not documented. Use it when the record supports chronic sinusitis but does not name a more specific site.
Clinical signs
Common findings include persistent nasal congestion, facial pressure, postnasal drainage, and reduced sense of smell. Clinical features vary; refer to documentation.
When to use this code
Use J32.9 when the provider documents chronic sinusitis without specifying maxillary, frontal, ethmoidal, sphenoidal, or pansinusitis. It also fits when the note confirms chronic sinus disease but the site is unclear. Check documentation if acute sinusitis or another nasal disorder is described instead.
Do not use for
Do not use this code for acute sinusitis or allergic rhinitis. Do not assign it when a more specific chronic sinusitis code is documented.
Coding tip
If the chart names the sinus involved, code the specific chronic sinusitis code rather than J32.9.
