W06 vs W31
W06 (Fall from bed) compared with W31 (Contact with other and unspecified 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. W06 carries an Excludes1 note covering W31: “fall (in) (from) machinery (in operation) (W28-W31)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
