Is V93 a billable ICD-10-CM code?

No. V93 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does V93 sit in the tabular list?

External causes of morbidity (V00-Y99), in the block Water transport accidents (V90-V94).

What cannot be coded together with V93?

V93 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

V93 — Other injury due to accident on board watercraft, without accident to watercraft

Non-billable headerICD-10-CM

V93 is a non-billable header ICD-10-CM code for other injury due to accident on board watercraft, without accident to watercraft. 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 V93

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.

civilian water transport accident involving military watercraft (V94.81-)
other injury due to accident to watercraft (V91.-)
military watercraft accident in military or war operations (Y36, Y37.-)

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

drowning and submersion due to accident on board watercraft, without accident to watercraft (V92.-)

Other codes that can never be billed with V93

These codes carry an Excludes1 note pointing at V93. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading V93 alone.

V93.6Machinery accident on board watercraft
W35Explosion and rupture of boiler
V91.0Burn due to watercraft on fire
W35.XXXAExplosion and rupture of boiler, initial encounter
W35.XXXDExplosion and rupture of boiler, subsequent encounter
W35.XXXSExplosion and rupture of boiler, sequela

Risk adjustment

V93 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 V93

8 child codes. Green means billable.
