W65-W74Accidental non-transport drowning and submersion

ICD-10-CM codes W65-W74 cover accidental non-transport drowning and submersion, within external causes of morbidity. The block holds 20 codes across 5 categories, of which 15 are billable and 5 are header codes that cannot be submitted on a claim. 20 of them (100%) require a 7th character.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • accidental drowning and submersion due to fall into water (W16.-)
  • accidental drowning and submersion due to water transport accident (V90.-, V92.-)

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.

  • accidental drowning and submersion due to cataclysm (X34-X39)

The 7th character in W65-W74

A code in this block is not complete without its 7th character, and a missing one is a rejected claim rather than a denied one: the clearinghouse never passes it on. 20 of the 20 codes here take one.

A
initial encounter
D
subsequent encounter
S
sequela
