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.3

The hospital deductible rose $60 from 2025, to $1,736 per benefit period.3 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.3

• Monthly premium: $202.90 (higher if your 2024 income exceeded $109,000 single or $218,000 married, under the income-related monthly adjustment amount, or IRMAA)3
• Annual deductible: $2833
• After the deductible: you pay 20% of the Medicare-approved amount for most services3

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.5

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.6

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.3,6
• 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.6
• 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.6

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.4 Part D now moves through three phases:

1. Deductible: you pay full price until you meet your plan's deductible (up to $615 in 2026).7
2. Initial coverage: you pay copays or coinsurance while your plan and drug makers cover the rest.
3. Catastrophic: once your out-of-pocket spending reaches $2,100, you pay $0 for covered drugs for the rest of the year.4

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 $40 to $50 a month, though actual premiums vary by plan.3 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.4 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.8

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.8,3

Your first 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.8 Outside it, Oklahoma insurers may use medical underwriting for some purchases.

Oklahoma also has a Medigap birthday rule (effective September 1, 2023): each year, a current Medigap policyholder with no coverage gap over 90 days gets a 60-day window starting on their birthday to switch, with no medical underwriting, to an equal-or-lesser plan with the same or a different carrier.9

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

If you're living on a fixed income, a Social Security check that has to stretch across rent, groceries, and the pharmacy, the standard Part B premium and Part D copays can force real trade-offs. A widow deciding whether she qualifies for QMB, or a retiree skipping a refill to make the month work, is exactly who these two programs exist for. Both can cut your Medicare costs sharply.

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.2

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.2 For all three programs, the 2026 resource limit is $9,950 for one person and $14,910 for a couple.2 The income figures are tied to the Federal Poverty Level and update each April.

Apply through the OHCA SoonerCare Supplemental page at oklahoma.gov, or contact Oklahoma SHIP for help with the application. Enrolling in any MSP automatically qualifies you for Extra Help.2

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.10 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 couple10
• Resource limits: $16,590 for an individual, $33,100 for a married couple10
• If you qualify for QMB, SLMB, or QI, you're enrolled in Extra Help automatically

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.11

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.11

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.12
