Pennsylvania is one of only two states that provides no rate protections for small employers buying health coverage for their employees. As a result, health insurers have almost unlimited freedom to compete for the business they want: employee groups with a low risk of needing medical care. Small employers, on the other hand, are suffering in Pennsylvania's relatively unregulated market due to the unpredictability and unaffordabilty of rates. Many have dropped coverage as a result, thus adding to the number of uninsured.
