Crush betw unpowr wtrcrft and oth wtrcrft/obj d/t clsn, sqla

This code describes injuries sustained by a person who was crushed between two or more watercraft, or between a watercraft and another object, specifically when the incident was due to a collision. The "sequela" designation indicates that this code is used for conditions that are residual effects or complications arising from the initial crushing injury, occurring after the acute phase has passed.

Apply this code when documenting chronic pain, nerve damage, non-union of fractures, or other long-term complications directly resulting from a crushing injury sustained in a watercraft collision. This code is appropriate for follow-up encounters where the focus is on managing these persistent effects.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, malunion).
• Ensure documentation clearly links the current condition to the past crushing injury from a watercraft collision.
• Verify that the collision involved unpowered watercraft and another watercraft or object, and that the injury mechanism was crushing.
