About these numbers: The premiums and deductibles below come from CMS for calendar year 2026, effective January 1. Medicare costs change every year. For the most current figures, contact Medicare at 1-800-633-4227 (1-800-MEDICARE) or Oklahoma SHIP at 1-800-522-0071.
Original Medicare: Parts A and B
Original Medicare is run directly by the federal government. The mechanics and costs are identical in Oklahoma and every other state.
Part A (Hospital Insurance)
Part A covers inpatient hospital stays, limited skilled nursing facility care, hospice, and some home health care.
| Cost | Amount |
|---|---|
| Monthly premium | $0 for most people (40+ quarters of work history) |
| Hospital deductible | $1,736 per benefit period |
| Hospital coinsurance, days 61-90 | $434 per day |
| Lifetime reserve days | $868 per day |
| SNF coinsurance, days 21-100 | $217 per day |
The hospital deductible rose $60 from 2025. A benefit period starts the day you're admitted and ends 60 days after you leave a hospital or skilled nursing facility. If you're readmitted after that window closes, the deductible applies again.
Part B (Medical Insurance)
Part B covers doctor visits, outpatient care, preventive services, durable medical equipment, and mental health care. It does not cover routine dental, vision, or hearing.
- Monthly premium: $202.90 (higher if your 2024 income exceeded $109,000 single or $218,000 married, under IRMAA)
- Annual deductible: $283
- After the deductible: you pay 20% of the Medicare-approved amount for most services
Delaying Part B past your enrollment window without other creditable coverage triggers a penalty of 10% for every 12 months you could have had it, for as long as you keep Part B.
Medicare Advantage in Oklahoma (Part C)
Medicare Advantage plans are sold by private insurers approved by Medicare. They cover everything Parts A and B do, except hospice, which Original Medicare continues covering. Most also bundle Part D drug coverage and extras like dental, vision, and hearing.
Plan availability in Oklahoma depends significantly on where you live. Oklahoma City metro and Tulsa metro generally offer the widest choice of plans. Rural counties, particularly in western Oklahoma and the panhandle, typically have fewer options. Plan networks, premiums, and benefits change every year and differ by county, so always check what's available at your specific ZIP code before you decide.
How These Plans Work
- You keep paying your Part B premium ($202.90) plus any plan premium. CMS estimates the average Medicare Advantage premium in 2026 at about $14 a month; many plans charge $0 extra.
- Most plans run on networks (HMO or PPO). Confirm your doctors and hospitals are in-network before enrolling.
- Plans typically require prior authorization for certain services, which Original Medicare generally does not.
- Every plan caps annual in-network out-of-pocket spending, federally limited to $9,250 in 2026; many plans set a lower cap. Original Medicare has no such cap.
Use the Medicare Plan Finder at medicare.gov to compare plans by ZIP code. Enter your doctors and prescriptions and it shows estimated costs. Oklahoma SHIP counselors can walk through the results with you for free.
Medicare Part D: Prescription Drugs
Part D covers outpatient prescription drugs. You can get it as a standalone plan paired with Original Medicare, or built into a Medicare Advantage plan.
The Inflation Reduction Act eliminated the old coverage gap (the donut hole), so that higher-cost middle stage is gone. Part D now moves through three phases:
- Deductible: you pay full price until you meet your plan's deductible (up to $615 in 2026).
- Initial coverage: you pay copays or coinsurance while your plan and drug makers cover the rest.
- Catastrophic: once your out-of-pocket spending reaches $2,100, you pay $0 for covered drugs for the rest of the year.
The $2,100 cap is new for 2026 (up from $2,000 in 2025) and is the figure that matters most for high-cost drugs. The average standalone Part D premium for 2026 is about $46.50 a month, though actual premiums vary by plan. Every plan also has to offer the Medicare Prescription Payment Plan, which lets you spread out-of-pocket drug costs into capped monthly installments instead of paying in full at the pharmacy. People who qualify for Extra Help often pay much less, sometimes nothing.

Medigap in Oklahoma
Medigap policies are sold by private insurers to fill the gaps in Original Medicare: the deductibles, coinsurance, and copays. They work only with Original Medicare, never with Medicare Advantage. Oklahoma offers the federally standardized plans, labeled A through N, regulated by the Oklahoma Insurance Department.
Plans C and F are closed to anyone who first became Medicare-eligible on or after January 1, 2020. Plan G is the popular choice for people newly eligible: it covers the Part A deductible, Part A and Part B coinsurance, and skilled nursing facility coinsurance, leaving only the $283 Part B deductible on you.
Oklahoma follows standard federal Medigap rules with no confirmed birthday rule or other state-specific expansion of guaranteed-issue rights. Your strongest window is the federal Medigap Open Enrollment Period: the six months that begin when you're 65 and enrolled in Part B. During that window, an insurer must sell you any plan at the standard rate regardless of health, with no medical underwriting. Outside it, Oklahoma insurers may use medical underwriting, meaning they can review your health history, charge more, or decline you.
Medigap or Medicare Advantage?
You cannot hold both. Medigap keeps you on Original Medicare with the freedom to see any provider who accepts Medicare nationwide, at a higher monthly premium. Medicare Advantage trades some of that flexibility for a network and often a lower upfront cost. For a side-by-side comparison, see our guide to Original Medicare vs. Medicare Advantage.
Help Paying for Medicare in Oklahoma
Two programs can significantly cut Medicare costs for people on fixed incomes.
Medicare Savings Programs (MSPs)
Oklahoma administers its Medicare Savings Programs through the Oklahoma Health Care Authority (OHCA), the state's Medicaid agency, commonly known as SoonerCare. Oklahoma uses the standard federal income tiers and resource limits, not higher state-set ones.
| Program | Individual | Couple | What it pays |
|---|---|---|---|
| QMB | Up to about $1,350 | Up to about $1,824 | Part A and B premiums, deductibles, coinsurance |
| SLMB | Up to about $1,616 | Up to about $2,184 | Part B premium |
| QI | Up to about $1,816 | Up to about $2,455 | Part B premium |
QMB is the most generous tier: it covers your Part B premium plus all deductibles and coinsurance, and federal law bars providers from billing a QMB enrollee for that cost-sharing. For all three programs, the 2026 resource limit is $9,950 for one person and $14,910 for a couple. The income figures are tied to the Federal Poverty Level and update each April.
Apply through the OHCA SoonerCare portal at okhca.org or contact Oklahoma SHIP for help with the application. Enrolling in any MSP automatically qualifies you for Extra Help.
Extra Help for Part D
Extra Help, also called the Low-Income Subsidy, pays Part D premiums, deductibles, and copays for people with limited income and resources. Since 2024, the partial-subsidy tier is gone, so everyone who qualifies now gets the full subsidy.
- Income limit (2026): up to about $1,995 a month for an individual, $2,705 for a couple
- Resource limits: $16,590 for an individual, $33,100 for a married couple
- If you qualify for QMB, SLMB, or QI, you're enrolled in Extra Help automatically
Apply through Social Security at ssa.gov or call 1-800-772-1213.
Medicare Enrollment Periods
Miss a deadline and you can face coverage gaps or permanent cost penalties. These windows are federal and the same in Oklahoma as everywhere else.
| Period | Dates | What you can do |
|---|---|---|
| Initial Enrollment | 7 months around your 65th birthday | Sign up for Parts A, B, and D; pick MA or Medigap |
| Annual Open Enrollment | Oct 15 - Dec 7 | Switch MA plans, move between MA and Original Medicare, change Part D |
| MA Open Enrollment | Jan 1 - Mar 31 | Switch MA plans or drop MA for Original Medicare (if already in MA) |
| General Enrollment | Jan 1 - Mar 31 | Sign up for Part B if you missed your initial window |
| Medigap Open Enrollment | 6 months from age 65 + Part B | Buy any Medigap plan at the standard rate, no health screening |
Changes made during Annual Open Enrollment take effect January 1 of the following year. If you're already receiving Social Security before 65, you're enrolled in Parts A and B automatically. If not, you sign up yourself through Social Security.
If you're still working past 65 and covered by an employer group health plan, you can delay Part B without penalty. You get an 8-month Special Enrollment Period starting the month after that coverage ends. COBRA and retiree coverage do not count as current-employer coverage for this purpose.

No. Oklahoma does not have a birthday rule or other state-specific guaranteed-issue right beyond the federal Medigap Open Enrollment Period. Your main guaranteed window is the six months after you turn 65 and enroll in Part B. Outside that window, Oklahoma insurers may use medical underwriting.
