ICD-10 Code J32.2 – Chronic ethmoidal sinusitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J32.2 – Chronic ethmoidal sinusitis
What it is
J32.2 identifies long-lasting inflammation of the ethmoid sinuses, the air spaces between the eyes. Use it when documentation states the condition is chronic rather than acute.
Clinical signs
Typical findings include persistent nasal congestion, facial pressure, postnasal drainage, and reduced smell. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chronic ethmoidal sinusitis, ethmoid sinus infection, or chronic inflammation limited to the ethmoid sinuses. It is appropriate when the record clearly identifies the ethmoid site and chronicity. Check documentation if the sinus location is unspecified or if the episode is acute.
Do not use for
Do not use J32.2 for acute ethmoidal sinusitis or for sinusitis involving other named sinuses without ethmoid involvement. If the record only says “sinusitis” with no site or duration, check documentation.
Coding tip
Verify both chronicity and ethmoid location in the note before assigning J32.2.
