Crush betw oth pwr wtrcrft & oth wtrcrft/obj d/t clsn, sqla

This code describes a sequela (late effect) resulting from an injury where an individual was crushed between a powered watercraft and another watercraft or object during a collision. The initial injury has resolved, but the patient is now presenting with a residual condition directly attributable to that past crushing incident.

Use this code when documenting a patient's current medical condition that is a long-term consequence of being crushed in a watercraft collision involving a powered vessel. This applies to follow-up encounters for chronic pain, nerve damage, deformity, or other lasting impairments stemming from the original trauma. Do not use for the initial acute injury.

• Always sequence this sequela code after the code describing the specific residual condition (e.g., chronic pain, malunion, nerve palsy).
• Ensure documentation clearly links the current condition to the past crushing injury from the watercraft collision.
• The "S" in the 7th character indicates sequela; do not use for initial or subsequent encounters for the acute injury.
