Oth injury due to oth accident to unsp watercraft, subs

This code signifies an injury sustained from an accident involving a watercraft other than a specified type (e.g., sailboat, motorboat) where the specific type of watercraft is not documented. It is used when the patient is receiving follow-up care for this injury after the initial treatment.

Apply this code for subsequent encounters related to injuries like sprains, fractures, or contusions that occurred due to an accident on an unspecified watercraft. This includes scenarios such as a patient returning for physical therapy after falling on a pontoon boat, or a follow-up visit for a laceration sustained during an incident on a personal watercraft where the specific type of watercraft isn't detailed.

• Ensure the documentation clearly indicates this is a subsequent encounter for the injury.
• Verify that the watercraft involved is not one of the more specifically categorized types in the V91 series.
• Always code the specific nature of the injury (e.g., fracture, sprain) first, followed by this external cause code.
