V99 vs W30
V99 (Unspecified transport accident) compared with W30 (Contact with agricultural machinery), 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. W30 carries an Excludes1 note covering V99: “agricultural transport vehicle accident (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).
