Why C is correct
Large groups are usually experience-rated: because their claims are statistically credible, the insurer sets rates primarily from the group's own claims history, adjusted for expected utilization and administrative expenses. Small groups lack credible experience and rely on community rating and pooling. Under the ACA, small-group plans use adjusted community rating, while large-group rating is more sensitive to the group's own experience, subject to federal rules that prohibit rating based on health status. Experience rating reflects the principle that a large group's own loss history is the most credible predictor of its future claims. The insurer then layers on administrative expense loads and pooling charges to protect against extraordinarily large individual claims, so the final rate blends the group's experience with broader risk-sharing mechanics.
Why the other options are wrong
- D) Rating reflects group experience and insurer costs; it is not uniform statewide. Large-group rates are not uniform across the state; they track each group's own claims experience, so different groups with different loss histories pay different rates.
- A) Individual underwriting is the hallmark of individual policies; large groups are rated on the group's aggregate experience. Individual underwriting and rating on personal health history are features of the individual and small-group markets, not of large-group medical rating.
- B) Premiums are set by insurers under state and federal rules, not by the federal government. Large-group premiums are set by competing insurers in the private market, and the federal government does not set rates for large employers.
Memory hook
Big groups = big data = their own claims set the price. Small groups pool; large groups experience-rate.
