J98.2 is a billable ICD code used to specify a diagnosis of interstitial emphysema. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code J982 is used to code Pneumomediastinum

Pneumomediastinum (from Greek pneuma - "air", also known as mediastinal emphysema) is pneumatosis (abnormal presence of air or other gas) in the mediastinum. First described in 1819 by René Laennec, the condition can result from physical trauma or other situations that lead to air escaping from the lungs, airways, or bowel into the chest cavity.
