W31.2

W31.2 — Contact with powered woodworking and forming machines

Non-billable headerICD-10-CM

W31.2 is a non-billable header ICD-10-CM code for contact with powered woodworking and forming machines. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

This code requires a 7th character

The appropriate 7th character is to be added to each code from category W31

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.

Contact with circular saw
Contact with molding machine
Contact with overhead plane
Contact with powered saw
Contact with radial saw
Contact with sander

Risk adjustment

W31.2 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.

How W31.2 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to W31.2.
