Author Q&A: Here’s how to navigate the complex world of Medicare

Signing up for Medicare is top of mind for the 4.1 million Americans turning 65 this year — a record number.

Medicare is the primary health insurance for 67 million people in the US, including adults age 65 or older and younger adults with long-term disabilities.

Coverage of Medicare benefits is provided through either traditional Medicare or Medicare Advantage private plans. And it’s complicated.

“Medicare provides great insurance, but it's not a ‘one-size-fits-all’ program,” Philip Moeller, a Medicare and Social Security expert and author of the new book, “Get What's Yours for Medicare: Maximize Your Coverage, Minimize Your Costs,” told Yahoo Finance. “It is easy to get lost in the program’s complexity.”

Medicare coverage begins for most Americans at 65 who are not covered by an employer-provided healthcare plan. The initial enrollment period is the three months before, the month of, and the three months after your 65th birthday. Miss your sign-up, and you start racking up late enrollment penalties and risk gaps in coverage.

The annual Medicare open enrollment period runs from Oct. 15 to Dec. 7 each year. That’s when those who are enrolled can make changes to their coverage, which goes into effect on Jan. 1 of the following year.

Changes include shifting from traditional Medicare to a Medicare Advantage plan (or vice versa), changing Medicare Advantage plans, and picking or switching between Medicare Part D prescription drug plans. The average Medicare beneficiary has access to 43 Medicare Advantage plans in 2024 and is able to choose from plans offered by eight firms.

Here's what Moeller had to say about navigating Medicare, edited for length and clarity:

Kerry Hannon: You say that there are three sets of decisions that, if properly handled, increase the odds of making Medicare work for people. Elaborate?

Phillip Moeller: First of all, enroll at the right time. Secondly, get the right package of coverage for you. And thirdly, spend some time learning how to use the coverage. Medicare is a very comprehensive program, but if you don't know what it covers and how to use it, its value to you is reduced.

So if you go back to the first thing, you need to understand the various enrollment periods for Medicare, whether you are aging into the program because you're turning 65, or whether or not you've been working and decide to retire at age 65 or later.

There are two traditional pathways into Medicare. One is traditional Medicare with a Part D drug plan, and usually a Medicare supplement plan or Medigap plan. The second approach, which has become increasingly popular, is Medicare Advantage.
