About J93.1
J93.1 is the ICD-10-CM diagnosis code for other spontaneous pneumothorax. It belongs to category J93 (pneumothorax and air leak), 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 2 subcodes must be used instead.
Within J93, choose J93.1 (Other spontaneous pneumothorax) only when documentation doesn't support a more specific option: spontaneous tension pneumothorax (J93.0), other pneumothorax and air leak (J93.8) and pneumothorax, unspecified (J93.9).
To report this condition, pick the subcode that matches the documentation: J93.11 (pneumothorax) and J93.12 (pneumothorax).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
