S22.20 vs S28.1
S22.20 (Unspecified fracture of sternum) compared with S28.1 (Traumatic amputation (partial) of part of thorax, except breast), 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. S22.20 carries an Excludes1 note covering S28.1: “transection of thorax (S28.1)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
