- Stonegate Advisors L.L.C., Chicago, a health insurance consulting firm, says it has conducted a health insurance broker survey and believes that groups with fewer than 50 employees are no longer simply repricing the plans they had the previous year.

Instead, small employers are allocating a fixed amount for health coverage and seeing what fits within that budget.

In some states, small employers are choosing “value-based” plans that give employees incentives for showing that they are trying to take good care of themselves.

Health plans should consider coping with the shift by finding ways to target services to fit the needs of specific membership segments, Stonegate says.
