ICD-10 Code J43.8 – Other emphysema (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J43.8 – Other emphysema
What it is
J43.8 identifies emphysema that does not fit the more specific ICD-10-CM emphysema categories. It refers to chronic destruction and enlargement of air spaces in the lungs, with airflow limitation.
Clinical signs
Clinical features vary; refer to documentation. Common findings include chronic shortness of breath, reduced exercise tolerance, and diminished breath sounds, but the record should support emphysema rather than another chronic lung disease.
When to use this code
Use J43.8 when the provider documents emphysema and does not specify centrilobular, panlobular, or other more defined subtypes. It is appropriate when the note clearly identifies emphysema but the type remains unspecified beyond “other.”
Choose this code only when the documentation supports emphysema as the diagnosis, not just chronic bronchitis or COPD alone. If the record is unclear, check documentation before coding.
Do not use for
Do not use J43.8 for more specific emphysema types that have their own codes. Also avoid it when the documentation only states COPD, chronic bronchitis, or another obstructive lung condition without emphysema.
Coding tip
Look for the exact provider wording; if the emphysema subtype is named, code the more specific option instead of J43.8.
