ICD-10 codes for COPD
COPD lives in category J44, and the fourth character does the work: stable disease, acute exacerbation, or acute lower respiratory infection. Exacerbation coding is one of the most commonly missed specificity opportunities in respiratory documentation.
COPD ICD-10 codes
Start with the primary code, then move to a more specific related code when the documentation supports it.
J44.9 | Chronic obstructive pulmonary disease, unspecified | ICD-10-CM |
J44.1 | COPD with (acute) exacerbation | ICD-10-CM |
J44.0 | COPD with acute lower respiratory infection Code also the infection (e.g. J18.-) | ICD-10-CM |
J43.9 | Emphysema, unspecified | ICD-10-CM |
F17.210 | Nicotine dependence, cigarettes, uncomplicated | ICD-10-CM |
Z87.891 | Personal history of nicotine dependence | ICD-10-CM |
Stable COPD at routine review is J44.9. Documented worsening of dyspnea, sputum, or cough beyond day-to-day variation supports J44.1. If the trigger is a lower respiratory infection, use J44.0 and code the infection as well. Always capture smoking status: F17.21- for current dependence, Z87.891 for former.
“COPD with increased breathlessness and purulent sputum for 3 days. Speaking in full sentences, SpO2 93% on air, scattered wheeze. No fever, chest clear of focal signs. Prednisolone 30 mg for 5 days and doxycycline started. Current smoker, 30 pack-years — cessation discussed.”

FactsContext extracts clinical facts first: diagnoses, symptoms, negatives, findings, test results, medications, and plan decisions.
The clinician can read and reuse the extracted medical context directly, independent of the generated note.
AI suggestions are not a substitute for clinician judgment, payer rules, local coding policy, or the official code set.
FAQ
What counts as an exacerbation for J44.1?
A documented acute worsening of respiratory symptoms beyond normal variation — typically increased dyspnea, sputum volume, or purulence — usually with a treatment change such as steroids or antibiotics.
How do I code COPD with pneumonia?
J44.0 (COPD with acute lower respiratory infection) plus the pneumonia code, e.g. J18.9.
Can AI catch the exacerbation I forgot to code?
Notat extracts symptom changes and treatment decisions as facts; if the note supports an exacerbation, it will suggest J44.1 with the exact sentence as evidence.
