V93 vs Y37
V93 (Other injury due to accident on board watercraft, without accident to watercraft) compared with Y37 (Military operations), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. V93 carries an Excludes1 note covering Y37: “military watercraft accident in military or war operations (Y36, Y37.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
