V99 vs W23
V99 (Unspecified transport accident) compared with W23 (Caught, crushed, jammed or pinched in or between objects), 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 carries an Excludes1 note covering V99: “injury caused by transport vehicle being used as a means of transportation (V01-V99)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
