ICD-10 Code J32 – Chronic Sinusitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J32 – Chronic sinusitis
What it is
J32 identifies chronic inflammation of one or more paranasal sinuses. Use it when the record documents sinusitis lasting a prolonged period or recurring enough to be considered chronic.
Clinical signs
Typical findings include persistent nasal congestion, facial pressure, and nasal discharge. Clinical features vary; refer to documentation.
When to use this code
Use J32 when the provider documents chronic sinusitis without a more specific sinus site or subtype. It may also apply when chronic sinus involvement is recorded but not further detailed. Check documentation for acute versus chronic distinction.
Do not use for
Do not use J32 for acute sinusitis or for allergic rhinitis alone. If the note does not clearly support chronic sinusitis, check documentation before coding.
Coding tip
Look for the word “chronic” and any specified sinus location before assigning the code.
