The situation

You served. You have VA health care and you like it. Your doctor is at the VA, your prescriptions come from the VA, and somewhere along the way a friend, or a coworker, or someone at a desk who should have known better, told you that you did not need Medicare Part B because the VA has you covered. We wrote about that man in August, here. Today is the next question. Suppose you did the right thing and kept Part A and Part B. Why would you ever look at a Medicare Advantage plan on top of it, especially the ones advertised with a $0 monthly premium?

First, the rule that makes the whole question exist.

The VA and Medicare do not work together

They are two separate systems that do not coordinate. Medicare's words: "Generally, Medicare and the U.S. Department of Veterans Affairs (VA) can't pay for the same items or services. Each time you get health care or visit a provider, you'll have to choose which benefit to use." The VA pays for care at VA facilities, or care it pre-authorizes somewhere else. Everything else, the emergency room two states away, the specialist with a shorter wait, the hospital your grandkids' town actually has, is Medicare's job.

That is why the VA itself answers the question the way it does. Should you sign up for Medicare at 65 if you already have VA care? The VA's answer, on its own site, is "Yes." Having Medicare "means you're covered if you need to go to a non-VA hospital or doctor." And one more thing the VA page will not tell you but Medicare's handbook does: VA coverage is not coverage from a current employer, so if you skip Part B at 65 there is no special window to fix it later. Just the penalty.

So you are on Original Medicare for the non-VA world. Here is what that world looks like.

Reason one: a number Original Medicare does not have

Original Medicare pays 80 percent of the approved amount for most outpatient care after the deductible. You pay the other 20 percent, and here is the sentence to read twice: "There's no yearly limit on what you pay out of pocket" unless you have some kind of supplemental coverage. Twenty percent of a bad year, with no ceiling.

Medicare Advantage plans are required to have a ceiling. Every one of them has a yearly limit on what you pay for covered services, and once you hit it, you pay nothing more for Part A and Part B care that year. For 2026, CMS sets the highest that in-network limit can be at $9,250, and many plans set theirs lower. For a veteran who gets most of his care at the VA and wants a backstop for the rest, a plan that adds a ceiling for a $0 monthly premium is exactly what it sounds like: a cap on the worst year, for the price of the Part B premium you were already paying.

Reason two: care outside the VA, on purpose

One of our callers put it better than I can. He wanted to keep Medicare "because if I'm somewhere and I can't use VA, I want to keep the Medicare." That is the whole reason. Winters somewhere else. Grandkids somewhere else. A wait at the VA you would rather not sit through for something a local specialist could see next week. An Advantage plan gives that non-VA care a structure, a network, a set of copays, a cap, instead of an open-ended 20 percent.

Reason three: the things the VA and Medicare both skip

Medicare notes that most Advantage plans offer extras Original Medicare does not cover, like vision, hearing, and dental, and that the extras vary plan to plan. One caller with military coverage told us the one thing it did not cover was the eye doctor. Those benefits are not why you choose a plan. They are a reason to look.

The honest catches

$0 premium is not $0 cost. You must keep Part A and Part B and keep paying the Part B premium, $202.90 a month in 2026, to be in any Advantage plan. You pay copays when you use the plan. The plan has a network, and the doctors and hospitals you would actually use outside the VA need to be in it. And a plan that you never use is money out the door, which is the fair criticism you will read elsewhere. Our answer is that "never use" is a guess about the future, and the cap is not.

Availability is real but not universal. In Arizona this year, 100 percent of people with Medicare have access to a $0-premium Advantage plan. In Nevada it is 97 percent. And none of this names a company or a plan, on purpose. Which one, if any, is a conversation about your ZIP code, your doctors, and your travel, not a headline.

What about your prescriptions?

What about your prescriptions?

Accepted Answer

Good news here. Your VA drug coverage counts as creditable coverage, so the Part D late enrollment penalty we will do the math on tomorrow does not apply to you as long as you keep it. If a plan you join includes drug coverage, you gain the option of filling something at a local pharmacy instead of VA mail order. You just cannot use both for the same prescription at the same time.

You have the VA. So why would a $0-premium Medicare Advantage plan be worth a look? Three reasons, and one is a number Original Medicare does not have.
