Is W24 a billable ICD-10-CM code?

No. W24 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does W24 sit in the tabular list?

External causes of morbidity (V00-Y99), in the block Exposure to inanimate mechanical forces (W20-W49).

W24 — Contact with lifting and transmission devices, not elsewhere classified

Non-billable headerICD-10-CM

W24 is a non-billable header ICD-10-CM code for contact with lifting and transmission devices, not elsewhere classified. 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 W24

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.

transport accidents (V01-V99)

Other codes that can never be billed with W24

These codes carry an Excludes1 note pointing at W24. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading W24 alone.

W20Struck by thrown, projected or falling object
W23Caught, crushed, jammed or pinched in or between objects

Risk adjustment

W24 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 to one of these instead W24

2 child codes. Green means billable.
