ICD-10 Code J34.89 – Other specified disorders of nose and nasal sinuses (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J34.89 – Other specified disorders of nose and nasal sinuses
What it is
J34.89 is used for a documented nasal or sinus disorder that does not fit a more specific ICD-10-CM code. It is a catch-all code for other specified conditions of the nose and nasal sinuses.
Clinical signs
Clinical features vary; refer to documentation. You may see nasal obstruction, congestion, discharge, pain, or other localized nasal or sinus findings that are described without a more precise diagnosis.
When to use this code
Use J34.89 when the provider identifies a specific nasal or sinus abnormality, but ICD-10-CM offers no exact match. It is also appropriate when the chart clearly describes an “other specified” disorder and the condition is not better classified elsewhere. Check documentation for laterality, acuity, or a more specific diagnosis before assigning this code.
Do not use for
Do not use this code for common, more specific nasal or sinus diagnoses that have their own ICD-10-CM code. Also avoid it when the record only says “nasal symptoms” without a documented disorder; check documentation.
Coding tip
Look for the exact provider wording and code the most specific diagnosis documented before defaulting to J34.89.
