Medicare 2026

Oklahoma City Medicare: your 2026 fall window to reshape 2027 coverage

OKLAHOMA CITY — Starting Wednesday, Oct. 15, 2026, people with Medicare in Oklahoma City can make changes to their drug and Medicare Advantage coverage for next year. The window closes Sunday, Dec. 7, 2026, and anything you lock in during those eight weeks starts Jan. 1, 2027.

This is the one stretch each fall when almost any Medicare member can switch things up — no special reason needed. If you like what you have, you do not have to do a thing. Your plan, if it is offered again in 2027, will simply renew with the updates spelled out in its Annual Notice of Change (ANOC), the booklet your insurer sends in September.

What you can actually change between Oct. 15 and Dec. 7

The Annual Enrollment Period (AEP) is broader than most people think. During the window, a person with Medicare can:

• Join a Medicare Advantage plan for the first time, if they have Parts A and B.
• Switch from one Medicare Advantage plan to another.
• Drop a Medicare Advantage plan and go back to Original Medicare (Parts A and B).
• Join, switch, or drop a stand-alone Part D drug plan.

Whichever path you pick, the new coverage begins Jan. 1, 2027. If you make more than one change during the window, the last one on file by Dec. 7 is the one that takes effect.

A note on Medigap (Medicare Supplement) plans: those are not part of AEP. Medigap has its own rules, and in most cases, once your initial six-month enrollment window has closed, insurers in Oklahoma can use medical underwriting to decide whether to sell you a policy.

What's new for 2027

A few 2027 numbers are already set by CMS, and they matter if you take prescription drugs:

• The Part D out-of-pocket cap rises to $2,400 in 2027 (it is $2,100 in 2026). Once your out-of-pocket drug spending hits that cap, you pay $0 for covered Part D drugs the rest of the year.
• The Part D maximum deductible is $700 in 2027 (up from $615 in 2026). Plans can set a lower deductible, but not higher.
• The Part D national base beneficiary premium for 2027 is $41.33. That is a formula input CMS uses — it is not what any specific plan charges.

Two big numbers are not out yet: the 2027 Part B standard premium and deductible, and the 2027 IRMAA income brackets that affect higher-income enrollees. CMS typically publishes those in the fall, often in November. We would rather wait than guess.

Also helpful to know: the Part D coverage gap (the "donut hole") was eliminated in 2025, so Part D now has three phases — deductible, initial coverage, and catastrophic. And the Medicare Prescription Payment Plan lets you spread your drug costs across the calendar year in monthly installments instead of paying at the pharmacy counter.

The Oklahoma City plan landscape

Oklahoma City sits in Oklahoma County, where CMS lists 60 Medicare Advantage plans from 9 carriers for 2026. All 60 include drug coverage. By plan type, that breaks down to 18 HMOs, 7 HMO-POS, 34 PPOs, and 1 PFFS plan. Twenty-three of them are Special Needs Plans (SNPs) — designed for people who qualify based on income, a chronic condition, or an institutional setting.

For 2027, nine plans are not returning to the county, eight are new, and seven have been renamed. If your plan is one of those, your ANOC or a non-renewal letter from your insurer will say so plainly. The table below lists every Medicare Advantage plan offered in Oklahoma County, by carrier, so you can see what is on the shelf before you shop.

Carriers serving the county include Aetna (CVS Health), American Health Advantage of Oklahoma, Blue Cross Blue Shield (HCSC), Centene (WellCare), CommunityCare Senior Health Plan, Devoted Health, GlobalHealth, Humana, and UnitedHealthcare.

One wrinkle to be aware of: CMS data shows zero stand-alone Part D plans listed in the Oklahoma County file for this year's landscape. If you want drug coverage and you stay with Original Medicare, use the Plan Finder at medicare.gov to see what Part D options are available by your ZIP code before Dec. 7.

How to make a good decision

Three things to pull out and read before you shop:

1. Your ANOC. Mailed in September. It tells you what is changing with your current plan — premium, drug list (formulary), copays, network, and extras. 2. Your drug list. Write down every prescription, dose, and how often you fill it. Formularies change every year. 3. Your doctors. If you are in a Medicare Advantage plan, confirm your providers are still in-network for 2027. Networks can shift.

Medicare's Plan Finder at medicare.gov/plan-compare lets you plug in your drugs and pharmacy and see your estimated yearly cost under each plan. It is the single most useful tool during AEP.
