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.
Notat writes the note — and suggests these codes
The same FactsContext™ engine that extracts codes here turns the full consultation into a structured clinical note, with each code tied to the sentence that supports it. You review and sign every note.
Try AI-assisted extraction with visible medical context
Paste a note or record audio. Notat’s FactsContext™ engine extracts the raw clinical facts first, then suggests codes from that context so you can inspect the evidence before using anything.

How to use this tool
1
Paste or dictate a de-identified clinical note — a few sentences is enough.

COPD ICD-10 codes
Start with the primary code, then move to a more specific related code when the documentation supports it.
| Code | Description | System |
|---|---|---|
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 |
How to choose the right code
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.
Documentation example
“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.”
Suggested:
Not direct transcript guessing
FactsContext extracts clinical facts first: diagnoses, symptoms, negatives, findings, test results, medications, and plan decisions.
Raw facts stay usable
The clinician can read and reuse the extracted medical context directly, independent of the generated note.
Built for review
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.
