V93.63Machinery accident on board other powered watercraft

V93.63 is the ICD-10-CM diagnosis code for machinery accident on board other powered watercraft. It belongs to category V93 (other injury due to accident on board watercraft, without accident to watercraft), block V90-V94 (water transport accidents) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within V93.6, choose V93.63 (other powered watercraft) only when documentation doesn't support a more specific option: merchant ship (V93.60), passenger ship (V93.61), fishing boat (V93.62), sailboat (V93.64) and unspecified watercraft (V93.69).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
