Have you turned 65 or is your birthday right around the corner? If so, you are starting to getting notices about Medicare and Medicare Supplement, and you probably have friends that are talking about it as well. There is so much detail and decisions around Medicare, it can be very confusing. You may wonder, if you have Medicare, do you even need a Supplement product? Medicare is great, but if you want to be fully covered without significant gaps, you need a supplement. 

Once you’ve decided you must buy a Medicare Supplement product, the next decisions are what type of Medicare Supplement plan to buy and what company you should choose. There are hundreds of companies operating in the United States selling supplements. Many of those companies have already filled your mailbox with information. Others blast their messages through TV advertising. 

How do choose the best carrier that will be easy to work with and pay your claims promptly? Which companies are best for pricing and benefits? In this article, we will give you the top ten best Medicare Supplement, and also give you tips on choosing the best company to protect your health decisions.


Tips for Choosing a Medicare Supplemental Company

The government mandates and structures the various Supplement Plans available. This is a huge benefit because plans between companies will be identical. Companies distinguish themselves through competitive pricing and by adding benefits. These factors may be attractive, but there are other critical items you need to consider before deciding on what to buy.

Financial Ratings

If companies are not financially stable, they may not pay your claims. They will be slow to act and cut costs with customer service. A struggling company will be difficult to work with. Financial rating companies examine insurance companies for stability. Pay attention to these companies and their rating scale and it will help you make good decisions. 

Moody’s, AM Best, and Comdex are the standards for insurance quality ratings. Moody’s top rating is Aaa. AM Best is A++. Comdex is a combined score of many rating agencies. They rate on a scale of 1-100. A great company will score between 85-100. 


Health Insurance is a new product in the insurance world compared to life and property companies. Many health companies were established inside of life companies. Company longevity is a great indicator the company will be around when you need them.

Company Size

Size is an indicator of financial strength and stability. Be wary of very small companies or startup health companies. They may be a great company but it is a red flag, and you should ask more questions.

Customer Feedback

Most state departments of insurance store customer complaints on insurance companies. Double-check with your state to see if the company you are considering has a higher than average number of complaints. This could be a great indicator of whether they are difficult at claim time.

The other rating organization to consider is J.D. Power. You are probably familiar with their car ratings, but they also rate insurance companies as well. The company doesn’t necessarily have to get the best grade, but they need to be a the top.

Choosing an Agent

Choosing a company is important, but choosing the right agent is critical. You need an expert who has spent the time and resources to determine the best carriers and products available. You need someone who has access to a vast number of options, so he can help you find the best product for your needs and budget. 

Not all agents are equal. Just like insurance companies, here are questions to asken choosing an agent.


Does the agent represent a wide variety of companies?

Be concerned if an agent only represents one or two companies. They may not be able to find you the best company for your needs. Because they represent few companies, they may be more concerned about their needs and not yours.


Does the agent have certifications?

Insurance certifications and designations are important. They demonstrate that the agent is committed to being an expert in his industry. They have spent their own money learning more about the products they sell. Also, most designations have a binding code of conduct or ethics statement. Agents who carry those designations are committed to bringing the value to their customers. CFP (Certified Financial Planner) is a good designation to keep your eye out for.


Are they involved in an insurance association?

Similar to designations and certifications, an agent who belongs to an association is committed to his business for the long-term and not looking for short-term sales. 


Does the agent have positive testimonials and reviews?

Nothing indicates how beneficial an agent can be apart from what other customers are saying about them. The quality of reviews and testimonials an agent gets is a perfect window on how they will perform for you.
