As you well know not all healthcare plans offer the same coverage. Ask for references from the healthcare companies that interest you. Talk to their customers. Check with other companies whose businesses are similar to yours to see what type of healthcare plans they offer to their employees. Do a little research and find out the financial stability of the company.
Cost is a major consideration.
Check to see how much premiums have increased through the years and compare to see if any benefits have been deleted or reduced. Is there a minimum number of employees that have to be enrolled or covered by the plan. Check on the deductibles, co-pays and limits. Expect performance standards from your coverage. The network shouldnt have a high provider turnover.
