Five steps to compare plans
- Make your list. Write down your doctors, specialists, hospitals, pharmacy and every medicine with its dose. Include doctors in nearby states if you use them.
- See which plans serve your county. Enter your ZIP code in Medicare Plan Finder or see plans for your ZIP code. Oklahoma has 50 Medicare Advantage plans open to everyone for 2027, but your county may have far fewer.
- Check networks and drug lists. Look up each doctor and hospital in the plan's provider directory, and each medicine in its formulary. Call the doctor's office to confirm they'll take the plan in 2027.
- Estimate total yearly costs. Add the plan premium, deductibles, copays for the care you expect and drug costs. Remember you also keep paying your Part B premium.
- Read the rules. Note whether the plan is an HMO or PPO, whether it needs referrals or prior approval, and how it covers care when you travel.
What to compare
| What to check | Where to find it |
|---|---|
| Doctors and hospitals in network | Provider directory; call the office |
| Your medicines and their tier | Formulary (drug list) |
| Premium, deductibles, copays and yearly limit | Summary of Benefits |
| Referrals, prior approval and travel rules | Evidence of Coverage |
| Extra benefits | Summary of Benefits |
Medicare Advantage plans may offer extra benefits Original Medicare doesn't cover, such as dental, vision, hearing or fitness. Extra benefits vary by plan and county, may have limits and costs, and not every plan offers them. Check a plan's Summary of Benefits or Evidence of Coverage.
Oklahoma points to keep in mind
- Rural counties. In seven Panhandle and western counties, no Medicare Advantage plan open to everyone is offered for 2027. There, compare Original Medicare, Part D and Medigap instead. See which counties.
- Plans ending. If your plan won't renew for 2027, see what to do if your plan is ending.
- SoonerCare. If you also have SoonerCare, ask about special needs plans. See SoonerCare and Medicare.
To compare plans from the companies they work with, you can request a call from a licensed insurance agent. See also Medicare Advantage in Oklahoma and when open enrollment is for 2027.

Frequently asked questions
Where do I find each plan's details?
Every plan publishes a Summary of Benefits and an Evidence of Coverage, plus a provider directory and a drug list (formulary). Medicare Plan Finder links to them. Current members also get an Annual Notice of Change each fall that lists next year's changes.
How do I check that a licensed insurance agent is licensed in Oklahoma?
The Oklahoma Insurance Department licenses insurance agents and has a Licensee Look Up tool on its website that shows a license's status and expiration date. Anyone who sells you a Medicare Advantage plan in Oklahoma must hold an Oklahoma license.
What if someone pressures me to switch plans?
You never have to decide on a call or at your door. If an agent or company misleads you, you can file a complaint with the Oklahoma Insurance Department at 800-522-0071 or online, and you can report suspected Medicare fraud to 1-800-MEDICARE.
Should I compare even if I'm happy with my plan?
Yes. Plans can change their networks, drug lists and costs each January. Read your Annual Notice of Change and check that your doctors and medicines are still covered for 2027.
