Anyone on the verge of retirement, unless they have the world'slargest golden parachute, is probably at least a little bit worriedabout how much they'll end up paying for health care onceactually retired.

Even with Medicare's help, health care premiums aren't exactlycheap, but there can be a shockingly large difference between whatone might pay for Medicare coverage in one state and what the samepremiums might cost elsewhere.

Thanks to a new app from HealthView Services, financial advisorscan now check out the main costs for health care in retirement tohelp members plan accordingly. The new HealthView Explorer appuses HealthView Services' advisor- and physician-reviewedmethodology to project retirement health care costs, drawing ondata from 50 million health care cases to project health care costsby age and state for individuals retiring at 65.

While you can learn more about the app here, as well aslook into the firm's free consumer-facing applications, we weregiven the scoop on the 10 most expensive and 10 cheapest states forhealthcare in retirement.

As you recover from sticker shock, please remember how thenumbers were generated:

• Costs are for Medicare Part B Premiums, Medicare Part DPremiums, and Supplemental Insurance Premiums.

• Surcharges for exceeding retirement Modified Adjusted GrossIncome thresholds are not included.

• Projections reflect costs for a healthy 65-year-old retiringtoday, living through age 84, totaling 20 years in retirement.

Here are the 10 most expensive states for health care:

1.Florida

Considering its large population of seniors, maybe it shouldcome as no surprise that Florida is the most expensive state forhealth care in retirement.

Medicare Parts B and D and supplemental insurance premiums addup to a hefty $152,184 for a 20-year-long retirement – andthat's before anyone actually needs care.

2. Michigan

Michigan's no bargain either, particularly since it comes in atjust a few small dollars short of Florida.

Twenty years' worth of health care premiums here will cost you$152,175 – not even a sawbuck's worth of savings over the SunshineState.

3.Maryland

That 20-year span of premiums is enough cheaper in Maryland fora few crab dinners, maybe, but not much else.

Retirees in the Free State will pay $151,438 for the privilegeof watching the sun rise over the Chesapeake Bay –definitely not free.

4. Massachusetts

$151,110. That's how much your retiree clients could pay justfor health care premiums over 20 years.

If they're not well off, getting Red Sox season tickets couldput them in the red.

5. Nevada

Retirees in the Silver State will find themselves spending afair amount of that silver to pay their health care premiums, whichwill cost them $151,014 over 20 years.

They could try a trip to Vegas to help – do they feel lucky?

6. Louisiana

Retirees in the Pelican State might wish, especially if they'refans of Dixon Lanier Merritt, that they had a beakful of money topay 20 years' worth of health care premiums here.

At the very least they'll need a thick wallet to hold the$149,661 it will cost them.

(And if you're wondering about that beakful of money and itsconnection to Merritt? Back in 1910, he wrote a very famouslimerick, often attributed to Ogden Nash, that goes,

“A wonderful bird is the pelican,
His bill will hold more than his belican,
He can take in his beak
Enough food for a week
But I'm damned if I see how the helican!”)

7.New Jersey

What? New Jersey not at the top of the “most expensive”list?

That's a surprise – but it's still no bargain to pay for 20years' worth of health care premiums in retirement in the GardenState, where it will cost $148,865. Better make that a victorygarden, so retirees can eat, too.

8. Illinois

Whether they live in the Chicago area or not, retirees will beblown away by the cost of 20 years of premiums. They'll need$147,203 to stay healthy – or try to – in the Prairie State.

9.Texas

Everything's big in Texas, so it should come as no surprise thathealth care premiums are, too.

Retirees in the Lone Star State can look forward to forking over$146,969 for the privilege of being covered – and that's beforethey set foot in a doctor's office.

10. Indiana

Hoosier retirees, prepare yourselves.

You'll need to set aside $145,235 just for 20 years of healthcare coverage. Even though the cost here is nearly $7,000 less thanin the most expensive state, it's no bargain.
