W29.3XXA — Contact with powered garden and outdoor hand tools and machinery, initial encounter
W29.3XXA is a billable, specific ICD-10-CM code for contact with powered garden and outdoor hand tools and machinery, initial encounter. It is valid for submission on a claim.
7th character "A" — initial encounter
The appropriate 7th character is to be added to each code from category W29
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.

Excludes1 inherited from the categories above W29.3XXA
These are not written on W29.3XXA, but they bind it: a note on a category applies to every code beneath it. Billing W29.3XXA with anything listed here is a denial.
Other codes that can never be billed with W29.3XXA
These codes carry an Excludes1 note pointing at W29.3XXA. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading W29.3XXA alone.

Risk adjustment
W29.3XXA does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code history
W29.3XXA has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
