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 once you've gone 60 days in a row without inpatient hospital care or skilled care in a 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. Original Medicare does not cover routine dental, vision, or hearing.3,6

• 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 qualifying for a Special Enrollment Period or a Medicare Savings Program triggers a penalty of 10% for every 12 months you could have had it, for as long as you keep Part B.7

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. Some plans go further and may help pay part or all of your Part B premium.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: CMS says there is no yearly limit on what you pay out of pocket unless you have supplemental coverage such as Medigap, Medicaid, employer, retiree, or union coverage.6

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).8
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 $34.50 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 with Original Medicare, and a Medigap policy can't pay a Medicare Advantage plan's copays, coinsurance, deductibles, or premiums. Oklahoma offers the federally standardized plans, labeled A-D, F, G, and K-N, regulated by the Oklahoma Insurance Department.9,6

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.10,9,3

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.9 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 window of at least 60 days starting on their birthday to switch, with no medical underwriting, to an equal-or-lesser plan with the same or a different carrier. The Oklahoma Insurance Department sets 60 days as the floor every issuer must meet, so an individual carrier may allow longer.11

Medigap or Medicare Advantage?

While you're in a Medicare Advantage plan it's illegal for anyone to sell you a Medigap policy unless you're switching back to Original Medicare. 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.6

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, where they run under the name SoonerCare Supplemental. Oklahoma Human Services (OKDHS) takes the applications and decides eligibility against the dollar standards in its Appendix C-1, and those standards equal the 2026 federal figures Social Security publishes in its row for all states except Alaska and Hawaii. The money test is not the first test: all three rules require that you be categorically related to aged, blind, or disabled, and that you meet Oklahoma's other SoonerCare conditions.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 standard is $9,950 for one person and $14,910 for an individual and spouse. Every figure here, income and resources alike, is a test of what Oklahoma counts, not of what you own or earn. OKDHS says some things you own do not count toward the resource limit, naming your home and furnishings, your car, and pre-paid funeral trusts up to $10,000, and that if you have employment income, more than half of it before taxes does not count toward the limit. A worker goes over your resources with you to decide what counts, and those lists are examples rather than the whole set.2 The $20 general income disregard applies to either earned or unearned income but not both, and a couple gets only one $20 disregard. If your spouse is not eligible for Medicare, Oklahoma runs both columns: your own countable income has to be at or under the individual standard, and the two of you together at or under the individual-and-spouse standard. A Part B premium withheld from your Social Security check gets added back before your income is compared to the limit. SLMB does not count State Supplemental Payments, and QI-1 does not count CHAMPUS payments for medical care or VA Aid and Attendance.2 These are not absolute cutoffs either: Social Security tells its own staff to encourage people to apply even when income or resources look somewhat higher than the state limits.2

SLMB and QI-1 are for people already enrolled in Medicare Part A, and a QI-1 recipient cannot be receiving or eligible for any other type of Medicaid benefit. To apply, visit or call a local OKDHS Human Services Center, or download the Request for Benefits form (PS-1 or 08MP001E) from the DHS forms website and send it to your local office. An application form and an interview are both required, and within 30 to 60 days you get a notice in the mail telling you whether you were approved.2 The OHCA SoonerCare Supplemental page describes the program, and Oklahoma SHIP will help you with the application. Enrolling in QMB, SLMB, or QI automatically qualifies you for Extra Help; QDWI, the fourth savings program, does not.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.12 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 in the 48 contiguous states and DC; Alaska and Hawaii are higher12
• Resource limits: $16,590 for an individual, $33,100 for a married couple, rising to $18,090 and $36,100 if you tell Social Security you expect to use some of your resources for burial expenses12
• If you qualify for QMB, SLMB, or QI, you're enrolled in Extra Help automatically2

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.14

Changes made during Annual Open Enrollment take effect January 1 of the following year. If you start receiving Social Security at least four months before you turn 65, you're enrolled in Parts A and B automatically. If not, you sign up yourself through Social Security.14

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, counted from the month that employment or coverage ends, whichever comes first. COBRA and retiree coverage do not count as current-employer coverage for this purpose, and if you're self-employed or your plan isn't available to everyone at the company, ask your insurer whether it counts as employer group health plan coverage before you delay; if it doesn't, sign up at 65. This Special Enrollment Period does not apply if you're eligible for Medicare based on End-Stage Renal Disease (ESRD).15
