Pneumothorax and air leak (J93) ICD-10-CM
The J93 code range covers pneumothorax and air leak with 10 ICD-10-CM diagnosis codes. 7 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

About the J93 Code Range
Pneumothorax and air leaks appear together in this category of respiratory conditions affecting the pleura.
The subdivisions separate spontaneous pneumothorax from other pneumothorax and air leaks. J93.0 identifies spontaneous tension pneumothorax. Other spontaneous pneumothorax divides into primary and secondary forms under J93.1. Under J93.8, the codes distinguish chronic pneumothorax, other air leak and other pneumothorax. J93.9 identifies pneumothorax without a specified type.
