COPD ICD-10 code
The ICD-10-CM code for copd is J44.9 — chronic obstructive pulmonary disease, unspecified. It is billable and valid for submission on a claim. There are 14 related codes, and which one you use depends on what the documentation supports.
Also written as chronic obstructive pulmonary disease, emphysema.
The mistake coders make here
J44.1 is COPD with acute exacerbation and J44.0 is COPD with acute lower respiratory infection. They are not interchangeable, and a documented exacerbation with an infection may need both.
