WHAT:NCCI has released new research examining how large workers compensation claims are emerging over time - specifically the changing balance between fast‑emerging and slow‑emerging large claims. The analysis shows that while overall large claim frequency has declined, a growing share of large claims now reach $1 million in incurred losses much earlier in the life of the claim. KEY FINDINGS:Fast-emerging large claims are becoming a larger share of all large claims. Overall large claim frequency has decreased, but claim emergence patterns are shifting. Earlier identification of severe claim characteristics—and improved claims management practices—may be contributing to fewer slow-emerging, “lurking” large claims.
