Type 1 Excludes
Type 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as J98.2. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Approximate Synonyms
  • Interstitial emphysema of lung
  • Mediastinal emphysema
  • Pneumomediastinum
Clinical Information
  • Pathologic accumulation of air in the interstitium of the lungs. It is caused by the rupture of alveoli and terminal bronchioles. It is most often seen in premature infants that need mechanical ventilation for respiratory distress syndrome.
  • Presence of air in the mediastinal tissues due to leakage of air from the tracheobronchial tree, usually as a result of trauma.
  • The presence of air in the mediastinum. It is caused by injury, most often esophageal or intestinal perforation.
