It’s that time of year again, when the trees become bare and days grow short, that one’s thoughts turn to health insurance. That’s right, the open enrollment window for renewing your existing health insurance plan or shopping for a new plan opens November 1st and runs through December 15th, 2018. For Minnesota residents, shopping for insurance means contacting a health insurance broker to get help in comparing different plans. Or, for those whose income qualifies them for financial help, applying and enrolling on the MNSure website. For those who live in states without their own exchange, plans can be compared on HeathCare.gov, the federal government’s national exchange site. Choosing the right health insurance plan depends on your family’s health and understanding which cost-sharing arrangement works best for you. The cost-sharing arrangement is how much you want to pay monthly for the insurance premium plus how much you are comfortable paying out-of-pocket for a doctor’s visit or medical procedure. You can pay less on a monthly basis for your premium if you are willing to pay more out of pocket for a doctor’s visit or medical procedure. The most prominent cost-sharing component is the plan deductible. This is the amount you pay every year before the insurance company pays its first dollar. Choosing a lower deductible amount and pushing the costs onto the insurance company sooner will result in a higher premium. By choosing the maximum deductible allowed, $7,900 for individual plans and $15,800 for a family plans in 2019, you will pay a lower monthly premium. Picking a high deductible plan with a lower premium may make sense for a healthy person who never needs health services, as well as someone comfortable with paying the out-of-pocket amount. Other ways that insurance plans share the cost is with co-pays and coinsurance. A copay is a fixed dollar amount that you pay every time you visit the doctor. That amount may be $30 with a typical insurance plan but it will be lower or possibly waived for a more expensive plan. Coinsurance is where the cost of a medical procedure is shared. The typical coinsurance arrangement kicks in after you meet the deductible amount. Then, you pay 20%, for example, of costs until you reach the maximum out-of-pocket limit amount. Finally, the out-of-pocket limit is the maximum amount that you will pay. It is the sum of the deductible plus the copays or coinsurance that you pay in any given year. Once you hit this limit, the insurance company pays 100% thereafter. This amount is established each year by the government as part of the Affordable Care Act. As noted above, for 2019, the maximums are $7,900 for individual plans and $15,800 for family plans. Once you understand how cost-sharing works, the cost difference between plans comes down to the services and prescription drugs that the plans cover. All plans are required to cover emergency services, hospitalization and maternity care, as well as mental health and substance-abuse treatment, at a basic level. All plans also cover the cost of an annual check-up and preventive care services (such as immunizations and mammograms) with any level of deductible. More expensive plans will also cover a greater level of preventative services, and higher levels of service, such as brand name drug coverage instead of generic-only drug coverage. So, as you rake up the leaves and pull out the winter coats, take time to review your health insurance plan because health insurance season will soon be here!
