W56.82Struck by other nonvenomous marine animals

W56.82 is the ICD-10-CM diagnosis code for struck by other nonvenomous marine animals. It belongs to category W56 (contact with nonvenomous marine animal), block W50-W64 (exposure to animate mechanical forces) 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 W56.8, choose W56.82 (Struck by other nonvenomous marine animals) only when documentation doesn't support a more specific option: Bitten by other nonvenomous marine animals (W56.81) and other contact with other nonvenomous marine animals (W56.89).

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.
