W16: Fall, jump or diving into water

Non-billable headerICD-10-CM

W16 is a non-billable header ICD-10-CM code for fall, jump or diving into water. 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 W16

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.

  • accidental non-watercraft drowning and submersion not involving fall (W65-W74)
  • effects of air pressure from diving (W94.-)
  • fall into water from watercraft (V90-V94)
  • hitting an object or against bottom when falling from watercraft (V94.0)

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.

  • striking or hitting diving board (W21.4)
