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

This code describes injuries sustained when a patient was crushed between an unpowered watercraft (e.g., canoe, kayak, rowboat) and another watercraft or object during a collision. This particular code is for encounters following the initial treatment of the injury.

Apply this code for follow-up visits, cast changes, medication adjustments, or physical therapy related to injuries from being crushed in such a watercraft collision. It is appropriate when the patient is receiving routine care during the healing phase, or for treatment of complications arising from the initial injury.

• Ensure the encounter is not the initial treatment for the injury; otherwise, an 'A' (initial encounter) suffix is required.
• Verify the mechanism of injury specifically involves being crushed between an unpowered watercraft and another watercraft or object.
• Always code the specific injury(ies) sustained in addition to this external cause code.
