Chronic obstructive pulmonary disease with (acute) lower respiratory infection
Diseases of the Respiratory System·Other chronic obstructive pulmonary disease·subcategory·FY 2027
COPD: COPD (chronic obstructive pulmonary disease) is a group of lung diseases that make it hard to breathe and get worse over time. Normally, the airways and air sacs in your lungs are elastic or stretchy. When you breathe in, the airways bring air to the air sacs. The air sacs fill up with air, like a small balloon. When you breathe out, the air sacs deflate, and the air goes out. If you have COPD, less air flows in and out of your airways because of one or more problems:

MS-DRGs
As the principal diagnosis, this code groups to these MS-DRGs (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.
Codes whose notes mention J44.0
If you are coding one of these, its note tells you to add J44.0 too (Code Also, Use Additional Code), code it first (Code First), or not use it together (Excludes1).
