Sometime in late October, I’ll host the 12th Annual Friends of Elaine Kortzeborn Medicare Open Enrollment Party.

Every year since 2005, I’ve helped a dozen or so my mom’s buddies review their Medicare Part D prescription drug insurance and make sure it still works for them.

At first, I ran into some resistance. Mom’s friends didn’t want to bother. They had coverage and didn’t see why they needed to keep checking their drug plans. After a couple of years, though, that attitude disappeared.

We kept finding that, every year, their health needs changed and so did the list of drugs covered by their plans. Shopping among the numerous plans and choosing the right one could mean saving hundreds of dollars a year.

Now, everyone’s on board to make sure they have coverage that’s right for them.

All this is just my way of reminding you that Medicare’s annual open enrollment season begins Oct. 15 and runs through Dec. 7. This is the time every year when you can sign up for a new Medicare drug or health plan, or switch the one you have now.

Any new coverage you select will take effect Jan. 1, 2017.

In addition to Part D drug plans, open enrollment applies to Medicare Advantage health plans, which are essentially managed care plans run by private insurers approved by Medicare.

If you have Original (traditional) Medicare and you’re satisfied with it, you don’t need to do anything during open enrollment.

If you have a Medicare Advantage health plan or Part D drug plan, keep in mind that these plans can make changes each year, including what they cover, how much they charge for monthly premiums and deductibles, and which doctors, hospitals, and pharmacies are in their networks.

Always review the materials your health or drug plan sends you, like the “Evidence of Coverage” and “Annual Notice of Change.” Make sure your plan still meets what you anticipate will be your health needs for next year. If you’re satisfied with your current plan, and your insurer is still offering it in 2017, you don’t need to make any changes.

Here are resources to help you compare your current coverage with new plan offerings for 2017. You can:
