J93 vs P25.1
J93 (Pneumothorax and air leak) compared with P25.1 (Pneumothorax originating in the perinatal period), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. J93 carries an Excludes1 note covering P25.1: “congenital or perinatal pneumothorax (P25.1)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
