"What's really important is if you are happy with your coverage, you don't have to change," said Frederic Riccardi, director of client services at the Medicare Rights Center.
By now you should have received your "Annual Notice of Change," which lists the changes in your plan, such as the premium and co-pays. It's so important that you review the document.
The notice will compare the benefits in 2014 with those you've received this year. In addition to your health-care choices, pay particular attention to your prescription-drug plan and the list of covered medications. Insurers change the drugs they cover, their procedures, their rates and sometimes their networks of doctors and hospitals.
But don't just focus on prices. Balance affordability with coverage, Riccardi says. Make sure the medications you need are still covered. Check to see if under your plan you need prior authorization, or if there are quality limits or set therapy, which means requiring a different drug before the plan will cover the one prescribed.
Here are some things you should know for the Medicare open enrollment:
* There are more high-quality plans to choose from. In fact, you may have received a letter from Medicare stating that your plan has received fewer than three stars (out of a scale of one to five) for three consecutive years. The letter will let you know that you can go on the Plan Finder and change to a plan with more stars.
* Average prescription-drug and Medicare health-plan-premium prices remain stable for next year. Most people don't pay a monthly premium for Part A because they have at least 40 quarters of Medicare-covered employment. Part A pays for inpatient hospital, skilled nursing facility, and some home-health-care services. If you pay a premium, you'll see a drop of $15 to $426, according to the Centers for Medicare & Medicaid Services. Beneficiaries who have between 30 and 39 quarters of coverage may buy into Part A at a reduced monthly premium rate, which is $234 for 2014, a decrease of $9.
* If you fall into Medicare's prescription-drug-coverage gap known as the "doughnut hole," you will get discounts of about 53 percent on covered brand-name drugs and 28 percent discounts on generics. This price break is the result of the Affordable Care Act's provisions to close this gap.
