Inclusion terms

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

  • Drowning NOS

Other codes that can never be billed with W74

These codes carry an Excludes1 note pointing at W74. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading W74 alone.

  • W16Fall, jump or diving into water

Risk adjustment

W74 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 W74 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 W74.

  • Drowning(accidental)

Code to one of these instead W74

3 child codes. Green means billable.
