W20 vs W23.0XXD
W20 (Struck by thrown, projected or falling object) compared with W23.0XXD (Caught, crushed, jammed, or pinched between moving objects, subsequent encounter), 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. W23.0XXD carries an Excludes1 note covering W20: “injury caused by struck by thrown, projected or falling object (W20.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
