What Was Measured?

Members who contacted their plan with a problem or to get information were surveyed for the Plan Service rating.

Why Is It Important?

The best HMOs give their members clear information, pay claims correctly, and solve problems quickly. Also, good customer service means the HMO tells you the cost that you would pay for a medical service.

An Excellent rating means that an HMO is among the top 10% of all plans nationwide.
