Buying Guide for the Best Medicare Supplement Insurance

These frequently asked questions can help you better understand Medicare Supplement Insurance. Read through the answers to increase your knowledge of the benefits you can access and how to choose a plan that is right for you.

Do I Need the Best Medigap Supplement Insurance?

The best Medicare Supplement Insurance provides additional coverage beyond Original Medicare. Plans cover part or all out-of-pocket expenses left after traditional Medicare insurance deductions. Purchasing this coverage is optional but can be a smart decision.

Original Medicare covers 80% of qualified expenses. Depending on your required medical services, the remaining 20% can be a significant cost. Consider whether you must stay in the hospital for a few days or require ongoing care for your condition. These treatments and services are often expensive and add up quickly.

The best Medicare Supplement Insurance policies help to alleviate some of the burdens of the cost of medical care. A plan can save you significant money and make necessary care more accessible. Many consumers consider the monthly premium cost worth it for the added peace of mind and potential financial assistance when they most need it.

What Is Covered by the Best Medicare Supplement Insurance?

Original Medigap typically covers 80% of approved medical costs, meaning you are responsible for 20%. This is where the best Medicare Supplement Insurance plans can help. They cover some or all of that 20%, so you pay less out of pocket.

The exact amount covered depends on the plan you choose. Each of the plans is designated by a letter name. While the federal government regulates them, the coverage can change yearly. Always review the newest information when selecting or changing your policy.

You can select a plan with a coverage amount, deductible, and premium cost that makes sense for you. If you pay more in premiums, your deductible will be lower, requiring less money to pay for services when needed.



How Does It Work with Original Medicare?

Medicare covers basic costs of medical care, and it divides areas of medical coverage into groups, using letters to distinguish them:

  • Part A covers hospital insurance, including inpatient services, hospice, and home health.
  • Part B is for preventative and medically necessary general care, such as doctor visits, outpatient services, and some home health.
  • Part C, or Medicare Advantage Plan, replaces Parts A and B and may lower out-of-pocket costs; however, you still must stay enrolled in Parts A and B and pay your Part B premium.
  • Part D covers prescription medications like some of the best weight loss pills.

One of the best Medigap Supplement Insurance plans can help you cover costs not paid by Medicare Parts A and B. It does not work with Parts C and D.  This means that they will typically cover things like co-pays to visit your doctor and partial payments for inpatient and outpatient services.

When Should I Enroll in a Best Medicare Supplement Insurance Plan?

It would be best if you first had Medicare Part A and B before you can enroll in the best Medicare Supplement Insurance plan. Most people enroll in Original Medigap when they meet the age requirement of 65. If you have a disability or other extenuating circumstances, you may be eligible for Medicare at an earlier age.

There is a six-month open enrollment period once you have Medicare Part B and have turned 65. During this period, insurance companies are required to approve your coverage, regardless of your current health or medical history.

If you wait to enroll or even switch companies, you may need to answer health questions and document pre-existing conditions. It benefits you and keeps costs down if you enroll during this six-month timeframe.

How Are Premium Costs Calculated?

The price of your Medigap Supplement Insurance premium is set by the company you select. While the plans themselves are government-regulated and supported, each provider chooses its rates and what, if any, extras to include. The average cost of the popular Plan G ranges from $110 to $160 per month.

Factors considered when calculating your premium price include age, gender, location, and possibly your tobacco use. In addition to these criteria, there are three pricing structures for Medigap plans. 

These are:

  • Attained-age-rated: These policies have rising premium costs as you get older
  • Issue-age-rated: The premiums for these policies are determined by inflation
  • Community-rated: These policies have consistent premium prices based on the area, where everyone enrolled pays the same amount

Since private insurers set their prices, you should compare rates from several companies to find the best deal. You can save money or even get a better value by researching before making a purchase.



How Do I Select the Best Medicare Supplement Insurance Provider for Me?

The best coverage for you depends on your age, location, and health needs. You will also need to do some research to compare the price of plans across a few reputable companies. Put some thought into what your medical needs are, as well as your budget.

If you expect to use your insurance more frequently, you may want to opt for a plan that covers more of the costs left after Original Medicare

Remember: if you choose a plan with a low monthly premium, you’ll have a higher deductible. You’ll pay more out of pocket when using your insurance plan.

The best strategy to find the best coverage and provider for you is to shop around. You can obtain quotes for comparison or work with a provider, such as United Medigap Advisors. If you need clarification on the multiple options, it can be advantageous to speak with a knowledgeable agent who can guide you through the process.
