ICD-10 Code J98.8 – Other specified respiratory disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J98.8 – Other specified respiratory disorders
What it is
J98.8 is used for a respiratory disorder that does not fit a more specific ICD-10-CM category. It captures a documented condition involving the respiratory system when the record names a distinct disorder but no better code is available.
Clinical signs
Clinical features vary; refer to documentation. You may see respiratory complaints, abnormal breathing findings, or imaging and exam results that support a specified disorder without a more precise diagnosis.
When to use this code
Use J98.8 when the provider documents a specific respiratory disorder and no other code describes it better. It is appropriate when the condition is clearly respiratory, but the chart does not support a more exact diagnosis. Check documentation for the exact wording and site involved.
Do not use for
Do not use J98.8 for nonspecific symptoms like cough or shortness of breath alone. Also avoid it when another ICD-10-CM code identifies the disorder more precisely.
Coding tip
Code the most specific respiratory diagnosis documented; use J98.8 only after confirming no more specific option applies.
