ICD-10 Code J34.8 – Other specified disorders of nose and nasal sinuses (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J34.8 – Other specified disorders of nose and nasal sinuses
What it is
J34.8 identifies a documented disorder of the nose or nasal sinuses that does not fit a more specific ICD-10-CM code. Use it when the provider names a distinct nasal or sinus condition, but no dedicated code exists.
Clinical signs
Clinical features vary; refer to documentation. You may see nasal obstruction, congestion, facial pressure, discharge, or other localized nasal or sinus findings depending on the specific disorder described.
When to use this code
Use J34.8 when the chart clearly describes an “other specified” nasal or sinus disorder and the condition is not better represented elsewhere. It is appropriate when the provider’s wording is specific enough to support this category but not a more precise code. Check documentation if the exact diagnosis is unclear.
Do not use for
Do not use J34.8 for common conditions that have their own code, such as sinusitis, deviated septum, or nasal polyps. If the record only says “nasal symptoms” without a diagnosis, check documentation.
Coding tip
Code the most specific documented nasal or sinus disorder first, and use J34.8 only when no more specific ICD-10-CM option applies.
