K22.3 vs S27.8
K22.3 (Perforation of esophagus) compared with S27.8 (Injury of other specified intrathoracic organs), 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. K22.3 carries an Excludes1 note covering S27.8: “traumatic perforation of (thoracic) esophagus (S27.8-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
