What is the best medicare supplement insurance plan

To help you find the best Medicare Supplement plan for you, we’ve highlighted three of the most popular plans below.

1. Blue Cross Blue Shield

According to Blue Cross Blue Shield (BCBS), Plans F and N are available in most areas. When you purchase a Medicare Supplement insurance policy from BCBS, you will have access to the following benefits:

  • A 30-day “free look” period—This means once you have your Medicare Supplement plan with BCBS, you are allowed 30 days to review the coverage. If you decide to change your mind within this period of time, you can get a full refund.
  • Gym benefit (in some states)—You’ll have free gym access to several fitness clubs and exercise classes.
  • Household discounts—If you and someone that lives with you both have a BCBS Medicare Supplement insurance plan, you may be eligible for a 5 percent discount on your premium.
  • Portable coverage—You can use your BCBS Medicare Supplement insurance plan anywhere in the U.S. that accepts Medicare.
  • Provider options—You can use any doctor who accepts Medicare.

BCBS Plan F has been the most popular and the most comprehensive plan, but it’s no longer available to new enrollees. The good news is if you had it before January 1, 2020, you can keep it.

With Plan F, you are covered for an array of benefits. These benefits include 100 percent coverage for:

  • Your Part A Medicare coinsurance and hospital costs (up to 365 additional days after Medicare benefits are used up)
  • Your Medicare Part B coinsurance or copayment
  • Part A Hospice Care coinsurance or copayment
  • Skilled nursing facility coinsurance
  • Part A and Part B deductibles
  • Part B excess charges
  • Emergencies for foreign travel (up to $50,000)
  • The first three pints of blood for a blood transfusion

Many seniors are now choosing Blue Cross Blue Shield’s Medicare Supplement Plan G. The only difference between Plan G and Plan F is that it won’t cover your Medicare Part B annual deductible (which is $203 in 2021). For this reason, the premium for Plan G is often less than that of Plan F.

2. AARP United Healthcare

The United Healthcare Medicare Supplement plan is also very popular. It offers Plans A, B, C, D, F, G, K, L, and N.

These plans include:

  • Low or no out-of-pocket copays, coinsurance fees, or deductibles
  • Coverage with plan features that stay the same from year to year
  • Prescription drug plans (Medicare Part D) that will work with your United Healthcare Medicare Supplement plan
  • The option to keep your doctor (you can choose from any doctors or hospitals that accept Medicare patients, without the need for referrals)
  • A Medicare Supplement plan you can use anywhere in the U.S.
  • Plan C, F, and G that offer emergency coverage for foreign travel

3. Humana

Humana is one of the largest medical providers in the U.S., offering a diverse line of insurance products. You can choose from its popular Medicare Supplement plans A, B, C, G, F, and K.

Here’s what these plans offer:

  • Plan A covers primary benefits like coinsurance for hospital benefits, your Part B coinsurance or copayment, your first three pints of blood, and your hospice care coinsurance or copayment.
  • Plan B covers the above, as well as your Part A deductible.
  • Plan C covers the above, as well as hospice care and skilled nursing facility coinsurance, your Part B deductible, and foreign travel.
  • Plan F covers the above, as well as any Part B excess charges.
  • Plan G covers the above, less your Part B deductible.
  • Plan K covers only Part A coinsurance or copayments, 50 percent of Part B coinsurance or copayments, 50 percent of hospice care coinsurance or copayment, 50 percent of skilled nursing facility care coinsurance and 50 percent of your Medicare Part A deductible. The Plan K out-of-pocket maximum is $6,220 in 2021.
  • Plan L covers what Plan K covers but 75 percent rather than 50 percent. The Plan L out-of-pocket maximum is $3,110 in 2021.
  • Plan N covers only a $20 copay for office visits and a $50 copay for emergency room visits. Otherwise, it covers everything in Plan G, less your Medicare Part B excess charges.

Medigap policies are standardized

Every Medigap policy must follow federal and state laws designed to protect you, and it must be clearly identified as "Medicare Supplement Insurance." Insurance companies can sell you only a standardized policy identified in most states by letters.

All policies offer the same basic 

benefits [glossary]

 but some offer additional benefits, so you can choose which one meets your needs. In Massachusetts, Minnesota, and Wisconsin, Medigap policies are standardized in a different way.

Each insurance company decides which Medigap policies it wants to sell, although state laws might affect which ones they offer. Insurance companies that sell Medigap policies:

  • Don't have to offer every Medigap plan
  • Must offer Medigap Plan A if they offer any Medigap policy
  • Must also offer Plan C or Plan F if they offer any plan
