V99 vs W01
V99 (Unspecified transport accident) compared with W01 (Fall on same level from slipping, tripping and stumbling), 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. W01 carries an Excludes1 note covering V99: “fall (in) (from) transport vehicle (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).
