Billable/Specific Code

J44.9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
The 2023 edition of ICD-10-CM J44.9 became effective on October 1, 2022.
This is the American ICD-10-CM version of J44.9 - other international versions of ICD-10 J44.9 may differ.

Type 2 Excludes

Type 2 Excludes Help

A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (J44.9) and the excluded code together.

Clinical Information

A chronic and progressive lung disorder characterized by the loss of elasticity of the bronchial tree and the air sacs, destruction of the air sacs wall, thickening of the bronchial wall, and mucous accumulation in the bronchial tree. The pathologic changes result in the disruption of the air flow in the bronchial airways. Signs and symptoms include shortness of breath, wheezing, productive cough, and chest tightness. The two main types of chronic obstructive pulmonary disease are chronic obstructive bronchitis and emphysema.
A disease of chronic diffuse irreversible airflow obstruction. Subcategories of copd include chronic bronchitis and pulmonary emphysema.
A type of lung disease marked by permanent damage to tissues in the lungs, making it hard to breathe. Chronic obstructive pulmonary disease includes chronic bronchitis, in which the bronchi (large air passages) are inflamed and scarred, and emphysema, in which the alveoli (tiny air sacs) are damaged. It develops over many years and is usually caused by cigarette smoking.
Chronic obstructive pulmonary disease (copd) makes it hard for you to breathe. Coughing up mucus is often the first sign of copd. Chronic bronchitis and emphysema are common copds. Your airways branch out inside your lungs like an upside-down tree. At the end of each branch are small, balloon-like air sacs. In healthy people, both the airways and air sacs are springy and elastic. When you breathe in, each air sac fills with air like a small balloon. The balloon deflates when you exhale. In copd, your airways and air sacs lose their shape and become floppy, like a stretched-out rubber band.cigarette smoking is the most common cause of copd. Breathing in other kinds of irritants, like pollution, dust or chemicals, may also cause or contribute to copd. quitting smoking is the best way to avoid developing copd. Treatment can make you more comfortable, but there is no cure.
Chronic, irreversible obstruction of air flow from the lungs.
