What Are the Best Oklahoma Medicare Supplement Plans?

Medicare Part A and Part B covers a large percentage of the costs of medical care and hospitalization for those who qualify. Also known as Original Medicare, Part A and Part B coverage does not cover all health care costs. Out-of-pocket expenses may include deductibles, copays and medical services obtained outside the United States. These costs can be covered partially or fully through your Medigap insurance policy.

You can choose from 10 Medicare Supplemental Plans in Oklahoma. Each of these plans offers specific types of coverage that are standardized across all insurance companies. For example, Medigap Plan A offers the same coverage no matter which insurance company offers it. Only the cost of the plan will vary from insurer to insurer. This standardized approach to Medicare Supplemental Plan coverage makes it simpler to choose the most affordable plan for your needs.

How Do I Enroll in an Oklahoma Medigap Plan?

If you are eligible for Medicare Part A and B and have enrolled in these insurance plans, you can enroll in the Medigap plan of your choosing. There are a few points to keep in mind regarding this process, however:

  • Beginning on the first day of the month in which you turn 65, you will have a six-month period during which you cannot be turned down for Medigap coverage. Insurers are required to provide you with the same price for premiums as they would for a completely healthy individual during this six-month period, which is known as the Medicare Supplement Open Enrollment Period. 

  • Failing to obtain Medicare Supplemental coverage during this six-month window, however, could increase the amount you will be required to pay for Medigap coverage and could make it difficult for you to obtain Medigap insurance at all. Pre-existing conditions that must be disregarded during your six-month initial enrollment period can be factored into the cost and risk of insuring you after that time.

  • If you have pre-existing conditions, you may be required to wait six months after your application to use the benefits of your Medigap coverage.

  • However, if you are covered by a private or an employer-paid insurance policy that covers your pre-existing conditions, you may be eligible for Medigap coverage and treatment from day one of approval.

  • Guaranteed issue rights come into play if you lose Medigap coverage because of circumstances outside your control. Oklahoma Medicare recipients who have had Medigap coverage that lapsed because of the failure or bankruptcy of the insurer are usually able to obtain replacement Medigap insurance on the same favorable terms as those offered during the first six months of eligibility. Additionally, if you switched from Medicare Advantage to Original Medicare, you may be eligible for guaranteed issue rights for your new Medigap coverage. This can help you enjoy lower costs for your Medicare Supplemental Plan coverage.
