ICD-10 Code J44.9 – Chronic obstructive pulmonary disease, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J44.9 – Chronic obstructive pulmonary disease, unspecified
What it is
J44.9 identifies chronic obstructive pulmonary disease when the record does not specify a subtype. Use it for chronic airflow limitation documented as COPD without further detail.
Clinical signs
Common findings include chronic cough, sputum production, dyspnea, wheeze, and reduced airflow on pulmonary testing. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents COPD, chronic obstructive airway disease, or chronic bronchitis/emphysema within COPD, but does not name a more specific form. It is also appropriate when the chart confirms COPD and no exacerbation or additional specification is recorded. Check documentation if asthma overlap or acute flare is mentioned.
Do not use for
Do not use J44.9 when the record specifies COPD with acute exacerbation, chronic bronchitis with acute exacerbation, or emphysema as the only diagnosis. Do not assign it if the documentation supports a different obstructive lung disorder.
Coding tip
Query for specificity when COPD is documented without subtype, exacerbation status, or associated chronic bronchitis/emphysema.
