About J93

J93 is the ICD-10-CM diagnosis code for pneumothorax and air leak. It belongs to block J90-J94 (other diseases of the pleura) and chapter 10 (diseases of the respiratory system). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: J93.0 (pneumothorax), J93.1 (pneumothorax), J93.8 (leak) and J93.9 (unspecified).

Don't report J93 together with the conditions in its Excludes1 note: congenital or perinatal pneumothorax (P25.1), postprocedural air leak (J95.812), postprocedural pneumothorax (J95.811), traumatic pneumothorax (S27.0) and 2 more.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
