MID looks at a number of factors, including but not limited to: recent and future costs of medical care, the insurance company's history of rate changes, its financial strength, premiums, and administrative costs. We also consider the insurance company's overall profitability, investment income, surplus, and public comments. Insurers must show that the new rate is reasonable considering the benefits. If the insurance company's data does not fully support the increase, MID can ask for more information or disapprove the increase.
