Alternative wordings a physician may use in the chart for this same code.
- Fall due to collision between Hovercraft (on open water) and other watercraft or other object
- Fall due to collision between Jet ski and other watercraft or other object
Excludes1 inherited from the categories above V91.23XS
These are not written on V91.23XS, but they bind it: a note on a category applies to every code beneath it. Billing V91.23XS with anything listed here is a denial.
Written on V91.2 — Fall due to collision between watercraft and other watercraft or other object
Excludes2 inherited from the categories above V91.23XS
Also inherited, and the opposite of Excludes1: these conditions are not part of V91.23XS, but a patient can have both, so you may code both.
Other codes that can never be billed with V91.23XS
These codes carry an Excludes1 note pointing at V91.23XS. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading V91.23XS alone.
- V93Other injury due to accident on board watercraft, without accident to watercraft
Risk adjustment
V91.23XS 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.
Code history
V91.23XS has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
