In simple words: This code indicates a long-term health problem that resulted from being hit by something falling on a boat or ship.

This code describes a sequela (late effect) resulting from being struck by a falling object while on an unspecified watercraft. It's used for the aftereffects of such an injury, not the initial injury itself.

Example 1: A passenger on a ferry is struck by a falling suitcase during rough seas. Months later, they continue to experience headaches and dizziness related to the head injury sustained., A sailor on a cargo ship is hit by a falling crate. Years later, they suffer from chronic back pain as a result of the initial injury., A person on a small recreational boat is hit by a falling fishing rod. A year later, they have persistent numbness in their hand where the rod impacted them.

Documentation should clearly link the current condition to the prior injury sustained on the watercraft. Details about the nature of the falling object, the date of the original accident, and the ongoing symptoms are essential. The initial injury itself should also be documented.
