About W29.3

W29.3 is the ICD-10-CM diagnosis code for contact with powered garden and outdoor hand tools and machinery. It belongs to category W29 (contact with other powered hand tools and household machinery), block W20-W49 (exposure to inanimate mechanical forces) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within W29 (contact with other powered hand tools and household machinery), W29.3 is specifically for contact with powered garden and outdoor hand tools and machinery. Related codes cover powered kitchen appliance (W29.0), electric knife (W29.1), other powered household machinery (W29.2), nail gun (W29.4) and other powered hand tools and household machinery (W29.8).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

Don't report W29.3 together with the conditions in its Excludes1 note: contact with powered lawn mower (W28).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
