Y93.1 is a non-billable header ICD-10-CM code for activities involving water and water craft. It cannot be billed on its own: choose one of the more specific child codes below.

Other codes that can never be billed with Y93.1
These codes carry an Excludes1 note pointing at Y93.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Y93.1 alone.
Risk adjustment
Y93.1 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.
