W20 vs W23.2XXS
W20 (Struck by thrown, projected or falling object) compared with W23.2XXS (Caught, crushed, jammed or pinched between a moving and stationary object, sequela), 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. W23.2XXS 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).
