ICD-10 Code J44.89 – Other specified chronic obstructive pulmonary disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J44.89 – Other specified chronic obstructive pulmonary disease
What it is
J44.89 identifies chronic obstructive pulmonary disease that is documented as a specific type not captured by the other COPD codes. Use it when the record clearly says “other specified” COPD or gives a named COPD variant not separately listed.
Clinical signs
Clinical features vary; refer to documentation. COPD commonly presents with chronic cough, sputum production, dyspnea, and airflow limitation, but you should code only what the provider specifies.
When to use this code
Use this code when the clinician documents a chronic obstructive pulmonary disease subtype that does not fit a more specific COPD code. It may apply when the note names a distinct COPD form and the chart supports that description. If the record is vague, check documentation before assigning J44.89.
Do not use for
Do not use J44.89 for unspecified COPD when the provider has not identified a more specific type. Also avoid it when the diagnosis is asthma, chronic bronchitis, emphysema, or another condition that is separately documented.
Coding tip
Code J44.89 only when the provider’s wording supports an “other specified” COPD diagnosis; otherwise query for clarification.
