S22.42XB vs S28.1
S22.42XB (Multiple fractures of ribs, left side, initial encounter for open fracture) 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. S22.42XB 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).
