J18.0 vs J18.2
J18.0 (Bronchopneumonia, unspecified organism) compared with J18.2 (Hypostatic pneumonia, unspecified organism), 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. J18.0 carries an Excludes1 note covering J18.2: “hypostatic bronchopneumonia (J18.2)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
