Is V90 a billable ICD-10-CM code?

No. V90 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does V90 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 V90?

V90 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

V90 — Drowning and submersion due to accident to watercraft

Non-billable headerICD-10-CM

V90 is a non-billable header ICD-10-CM code for drowning and submersion due to 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 V90

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-)
fall into water not from watercraft (W16.-)
military watercraft accident in military or war operations (Y36.0-, Y37.0-)
water-transport-related drowning or submersion without accident to watercraft (V92.-)

Other codes that can never be billed with V90

These codes carry an Excludes1 note pointing at V90. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading V90 alone.

V91.2Fall due to collision between watercraft and other watercraft or other object
V92Drowning and submersion due to accident on board watercraft, without accident to watercraft
V92.07Drowning and submersion due to fall off water-skis
V92.07XADrowning and submersion due to fall off water-skis, initial encounter
V92.07XDDrowning and submersion due to fall off water-skis, subsequent encounter
V92.07XSDrowning and submersion due to fall off water-skis, sequela
V92.08Drowning and submersion due to fall off other unpowered watercraft
V92.08XADrowning and submersion due to fall off other unpowered watercraft, initial encounter

Risk adjustment

V90 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 V90

5 child codes. Green means billable.
