What is the ICD-10 code for COPD?

The ICD-10-CM code for COPD is J44.9 when documented without further specification. More specific documentation changes the code — see the scenario table.

Yes — J44.9 is a billable ICD-10-CM code, but payers expect the most specific code the documentation supports.

ICD-10 Code for COPD

The ICD-10-CM code for COPD is J44.9 when documented without further specification. COPD codes to J44.9 only when stable and uncomplicated; exacerbations and concurrent lower-respiratory infections each change the code.

Which Code Should You Use?

J44.9 — Chronic obstructive pulmonary disease, unspecified

COPD, uncomplicated/stable.

J44.1 — Chronic obstructive pulmonary disease with (acute) exacerbation

COPD with acute exacerbation.

J44.0 — Chronic obstructive pulmonary disease with (acute) lower respiratory infection

COPD with an acute lower respiratory infection - code also the infection (e.g., J18.9, J20.9).

J43.9 — Emphysema, unspecified

Emphysema documented WITHOUT chronic bronchitis/COPD language.

What to Document

Exacerbation status at the encounter.
Any concurrent lower respiratory infection (drives J44.0 + infection code).
Tobacco dependence or exposure (use additional code F17.-, Z87.891, Z77.22).

Coding Notes

Per the Excludes/instructional notes, asthma with COPD and emphysema-with-chronic-bronchitis combinations follow the J44 category rules - documentation wording matters.
