ICD-11 code : CB21.1;
Preferred Label : Other spontaneous pneumothorax;
ICD-11 definition : Spontaneous pneumothorax that is not tension pneumothorax is included in this classification
They include primary spontaneous pneumothorax without tension and secondary spontaneous
pneumothorax without tension. Primary spontaneous pneumothorax occurs in patients
without underlying pulmonary disease, classically in tall, thin young men in their
teens and 20s. It is thought to be due to spontaneous rupture of subpleural apical
blebs or bullae that result from smoking or that are inherited. It generally occurs
at rest, although some cases occur during activities involving reaching or stretching.
Primary spontaneous pneumothorax also occurs during diving and high-altitude flying
because of unequally transmitted pressure changes in the lung. Secondary spontaneous
pneumothorax occurs in patients with underlying pulmonary disease. It most often results
from rupture of a bleb or bulla in patients with severe COPD, HIV-related Pneumocystis
jirovecii infection, cystic fibrosis, or any underlying pulmonary parenchymal disease
Secondary spontaneous pneumothorax is more serious than primary spontaneous pneumothorax
because it occurs in patients whose underlying lung disease decreases their pulmonary
reserve.;
