W69Accidental drowning and submersion while in natural water

Non-billable headerICD-10-CM

W69 is a non-billable header ICD-10-CM code for accidental drowning and submersion while in natural 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 code W69

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.

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Accidental drowning and submersion while in lake
  • Accidental drowning and submersion while in open sea
  • Accidental drowning and submersion while in river
  • Accidental drowning and submersion while in stream

Other codes that can never be billed with W69

These codes carry an Excludes1 note pointing at W69. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading W69 alone.

  • W16.111Fall into natural body of water striking water surface causing drowning and submersion
  • W16.111AFall into natural body of water striking water surface causing drowning and submersion, initial encounter
  • W16.111DFall into natural body of water striking water surface causing drowning and submersion, subsequent encounter
  • W16.111SFall into natural body of water striking water surface causing drowning and submersion, sequela
  • W16.121Fall into natural body of water striking bottom causing drowning and submersion
  • W16.121AFall into natural body of water striking bottom causing drowning and submersion, initial encounter
  • W16.121DFall into natural body of water striking bottom causing drowning and submersion, subsequent encounter
  • W16.121SFall into natural body of water striking bottom causing drowning and submersion, sequela

Risk adjustment

W69 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 W69 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 W69.

  • Drowninginnatural water(lake) (open sea) (river) (stream) (pond)

Code to one of these instead W69

3 child codes. Green means billable.
