ICD-10 Code J39.8 – Other specified diseases of upper respiratory tract (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J39.8 – Other specified diseases of upper respiratory tract
What it is
J39.8 identifies other specified disorders affecting the upper respiratory tract that do not fit a more specific ICD-10 category. Use it when the condition is documented, but no exact named code is available.
Clinical signs
Clinical features vary; refer to documentation. Findings may involve throat, nasal, or upper airway complaints, but you should code only when the provider specifies a distinct upper respiratory tract disorder.
When to use this code
Use J39.8 when the record names an upper respiratory tract condition that is not indexed elsewhere in ICD-10-CM. It is appropriate for documented “other specified” disorders after you confirm no more specific code applies. If the diagnosis is vague or incomplete, check documentation before assigning this code.
Do not use for
Do not use J39.8 for common infections, chronic sinus disease, or conditions with their own specific ICD-10 codes. If the provider documents a more exact diagnosis, code that condition instead.
Coding tip
Look for the provider’s exact wording and verify that “other specified” is the best index match before coding J39.8.
