ICD-10 Code J98 – Other respiratory disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J98 – Other respiratory disorders
What it is
J98 covers respiratory conditions that do not fit more specific codes in the respiratory system chapter. Use it when the record identifies an “other” respiratory disorder and no narrower diagnosis is documented.
Clinical signs
Clinical features vary; refer to documentation. Findings may include nonspecific respiratory complaints, abnormal breathing patterns, or structural airway problems, depending on the exact disorder recorded.
When to use this code
Use J98 when the provider documents a respiratory disorder that is not classified elsewhere and the note does not support a more specific code. It is appropriate for unspecified “other” respiratory conditions after careful review of the chart. If the diagnosis is described more precisely, code that condition instead.
Do not use for
Do not use J98 for clearly identified diseases such as asthma, COPD, pneumonia, or acute upper respiratory infections. Check documentation if the chart supports a more specific respiratory diagnosis.
Coding tip
Before assigning J98, verify that no more specific ICD-10 code matches the documented respiratory condition.
