Is W23.0 a billable ICD-10-CM code?

No. W23.0 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does W23.0 sit in the tabular list?

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

What cannot be coded together with W23.0?

W23.0 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above W23.0 (W23) and apply to it just the same.

W23.0 — Caught, crushed, jammed, or pinched between moving objects

Non-billable headerICD-10-CM

W23.0 is a non-billable header ICD-10-CM code for caught, crushed, jammed, or pinched between moving objects. 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 W23

A: initial encounter
D: subsequent encounter
S: sequela

Excludes1 inherited from the categories above W23.0

These are not written on W23.0, but they bind it: a note on a category applies to every code beneath it. Billing W23.0 with anything listed here is a denial.

Written on W23 — Caught, crushed, jammed or pinched in or between objects

injury caused by cutting or piercing instruments (W25-W27)
injury caused by firearms malfunction (W32.1, W33.1-, W34.1-)
injury caused by lifting and transmission devices (W24.-)
injury caused by machinery (W28-W31)
injury caused by nonpowered hand tools (W27.-)
injury caused by transport vehicle being used as a means of transportation (V01-V99)
injury caused by struck by thrown, projected or falling object (W20.-)

Risk adjustment

W23.0 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 W23.0 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 W23.0.

Crushed›between objects(moving) (stationary and moving)
Jammed›between objects(moving) (stationary and moving)
Pinched›between objects(moving) (stationary and moving)
Caught›between›folding object
Caught›between›objects(moving)
Caught›between›sliding door and door frame
