Questions

Can I change my Medicare supplement plan in Oklahoma?

Yes. You can apply to change Medigap policies any time, and Oklahoma gives you a yearly 60-day window starting on your birthday to switch to a policy with the same or lesser benefits, from any company, without health questions. Otherwise, or for more benefits, the new company can review your health and may say no.

The birthday rule is in OAC 365:10-5-129(f), effective September 1, 2023. To use it you must have had Medigap coverage with no gap longer than 90 days. OID's chart shows, for example, that a Plan G holder can move to Plan A, B, D, G, K, L, M or N, or a high-deductible F or G, and a Plan N holder can move to Plan M or N. See the full chart on does Oklahoma have a Medigap birthday rule.

Common reasons Oklahomans switch

  • Price. Plans with the same letter have the same standardized benefits from every company, so switching to the same letter at a lower premium changes the price, not the coverage.
  • Fewer benefits. Some people move from Plan G to Plan N to lower their premium in exchange for some copays.
  • Company service. You can move to a different company under the birthday rule.

How to switch safely

  1. Check your birthday window. Apply within the 60 days that start on your birthday to avoid health questions.
  2. Apply for the new policy first. Don't cancel the old one yet.
  3. Wait for approval and a start date. Coverage usually starts on the first of the month after the company accepts your application.
  4. Cancel the old policy in writing. Do it once the new policy is in force, and keep a copy.

Don't let anyone rush you into dropping a policy. If someone misleads you to get you to switch, you can file a complaint with the Oklahoma Insurance Department at 800-522-0071.

To compare Medigap policies from the companies they work with, you can request a call from a licensed insurance agent. See Medigap in Oklahoma.

Frequently asked questions

Does Medicare's fall open enrollment let me switch Medigap plans?

No. The October 15 to December 7 open enrollment period is for Medicare Advantage and Part D plans. Medigap switching in Oklahoma follows the birthday rule and federal guaranteed-issue rights instead.

Will I lose credit for the Part B deductible if I switch mid-year?

The Part B deductible is a calendar-year amount and doesn't reset when you change policies, the Oklahoma Insurance Department says, but your new plan may not cover it. High-deductible plans' deductibles may restart with a new policy, so ask the company.

Can my company raise my premium?

Yes. Medigap premiums can go up, and attained-age policies also rise as you get older. Oklahoma's birthday rule gives you a yearly chance to shop for a lower price for the same or lesser benefits.

Can I return a new policy if I change my mind?

Yes. The Oklahoma Insurance Department's buyer's guide describes a 30-day period to review a new Medicare supplement policy and return it for a refund. Keep your old policy until you're sure.
