V99 vs W15
V99 (Unspecified transport accident) compared with W15 (Fall from cliff), 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. W15 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).
