J95: Postprocedural respiratory disorders, not elsewhere classified

J95.9: Postprocedural respiratory disorder, unspecified

When we breathe, the air gets into the body via the respiratory tract. The respiratory tract can be divided into the upper and the lower respiratory tracts. The nose and throat form part of the upper respiratory tract. The lower respiratory tract begins at the larynx. This includes the trachea and the bronchia.

You need lungs to breath. When we breathe in, oxygen enters the lungs and accumulates in the blood. This blood then flows to the heart. The heart then pumps the oxygen-rich blood throughout the body. All of the organs are supplied with oxygen as a result.

You received a medical examination or treatment. A disease in your airways subsequently occurred. The medical examination or treatment is the cause of this disease.
