Medicare in Louisiana works the same way it does everywhere else in the country, with two state-specific wrinkles worth knowing: an annual birthday-rule window that lets you switch Medigap plans without medical underwriting, and help paying premiums through Healthy Louisiana and the state’s Medicare Savings Programs. You qualify at 65 if you or a spouse paid Medicare taxes for at least 10 years, or earlier if you meet a disability rule. In 2026, the standard Part B premium is $202.90 per month.
Who Qualifies
You qualify for Medicare at 65 if you are a U.S. citizen or permanent legal resident and you or your spouse worked and paid Medicare taxes for at least 10 years, which is 40 calendar quarters of covered employment. Meeting that threshold means no monthly premium for Part A. If you fall short, you can still enroll in Part A but you will pay a premium for it.1HHS.gov. Who’s Eligible for Medicare?
Three situations open Medicare to people under 65: 24 months of Social Security Disability Insurance benefits, an ALS diagnosis (coverage starts immediately, no waiting period), or end-stage renal disease requiring dialysis or a kidney transplant, with a start date tied to when treatment begins.2Medicare.gov.

What Medicare Covers
Original Medicare has two parts. Part A (hospital insurance) pays for inpatient hospital stays, skilled nursing facility care after a qualifying hospital stay, hospice, and some home health services. Part B (medical insurance) covers doctor visits, outpatient care, preventive screenings, vaccines, durable medical equipment, and some home health care. Everyone pays a monthly premium for Part B; most people pay nothing for Part A.3Medicare.gov. Parts of Medicare
Prescription drugs are handled separately through Part D. Part D plans are sold by private insurers approved by Medicare, and premiums and covered drug lists vary by plan. You enroll in Part D on top of Original Medicare, or you get it built into a Medicare Advantage plan.3Medicare.gov. Parts of Medicare
2026 Costs
The standard Part B premium is $202.90 per month in 2026, with a $283 annual deductible. After the deductible, you generally pay 20 percent of the Medicare-approved amount for covered services, and there is no annual out-of-pocket cap on that 20 percent.4Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles
Part A cost sharing kicks in when you are admitted to a hospital. The 2026 deductible is $1,736 for the first 60 days of a stay. Days 61 through 90 cost $434 per day in coinsurance. Beyond day 90, Medicare draws from 60 lifetime reserve days at $868 per day, and those reserve days do not renew once used.5Centers for Medicare & Medicaid Services.

Higher Premiums for Higher Earners
If your modified adjusted gross income exceeds certain thresholds, you pay a surcharge on top of the standard Part B and Part D premiums, called the Income-Related Monthly Adjustment Amount (IRMAA). It is based on your tax return from two years earlier. For 2026, the Part B surcharge begins when individual income tops $109,000 or joint income tops $218,000, and it rises through several brackets. At the top bracket (individual income of $500,000 or more, joint income of $750,000 or more), the surcharge adds $487.00 per month to Part B and $91.00 per month to Part D.4Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles
If a life-changing event like retirement, divorce, or the death of a spouse has significantly lowered your income, you can ask Social Security to use a more recent tax year.4Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles
Original Medicare With Medigap, or Medicare Advantage
Every Louisiana beneficiary makes one fundamental choice: stay with Original Medicare (usually adding a Medigap policy and a stand-alone Part D plan) or enroll in a Medicare Advantage plan that bundles everything.
Original Medicare lets you see any doctor or use any hospital in the country that accepts Medicare, with no referrals. The weakness is that 20 percent coinsurance with no annual cap, so a serious illness can add up quickly. A Medigap (Medicare Supplement) policy from a private insurer fills the gaps: copayments, coinsurance, and deductibles. Medigap plans are standardized by letter (Plan A, Plan G, Plan N, and so on), so a Plan G from one company covers the same benefits as a Plan G from another; only the premium differs. Medigap does not include drug coverage, so a separate Part D plan is needed if you want drug benefits.6Medicare.gov. Get Medigap Basics
Medicare Advantage plans (Part C) are sold by private insurers and bundle Part A and Part B into one plan, usually with Part D drug coverage and often extras like routine dental, vision, or hearing. Many charge $0 in additional premium beyond the Part B premium you continue to pay. The trade-off is the network: most plans are HMOs or PPOs, so you pay more (or nothing is covered) outside the plan’s network. This matters if you see specialists across state lines or split your year between Louisiana and another state. You cannot hold both a Medicare Advantage plan and a Medigap policy.7Medicare.gov.

The Louisiana Medigap Birthday Rule
This is the piece of Medicare in Louisiana that most beneficiaries do not know about. Starting on your birthday each year, state law gives you 63 calendar days to switch to any Medigap policy with equal or lesser benefits sold by your current insurer or an affiliate licensed in Louisiana. The insurer cannot deny you, charge more, or impose waiting periods based on your health.9Louisiana State Legislature. Louisiana Revised Statutes 22:1112
In most states, switching Medigap plans after your initial enrollment means medical underwriting, and a serious health condition can lead to denial or an unaffordable premium. The birthday rule lets you shop the same coverage level for a lower premium every year without that risk. The limits: you can move to a plan with the same or fewer benefits (Plan G to Plan N, for instance, but not Plan N to Plan G), and only within the same insurer family.
Separately, federal law gives you a one-time, six-month Medigap open enrollment period that starts the month your Part B coverage begins. During those six months, any insurer selling Medigap in Louisiana must sell you any policy it offers, regardless of your health. After that closes, medical underwriting generally applies unless a federal guaranteed-issue right kicks in or you use the birthday rule.6Medicare.gov. Get Medigap Basics
Enrollment Windows and Penalties
Your Initial Enrollment Period is seven months long, centered on the month you turn 65: three months before, your birthday month, and three months after. Enrolling during or before your birthday month starts coverage sooner; waiting until the final three months delays it.10Centers for Medicare & Medicaid Services. Original Medicare (Part A and B) Eligibility and Enrollment – Section: Initial Enrollment Period (IEP)
Miss it, and the General Enrollment Period runs January 1 through March 31 each year. Coverage starts the month after you enroll, and a late enrollment penalty will usually apply.11Medicare.gov. When Does Medicare Coverage Start?
The Annual Enrollment Period runs October 15 through December 7. During that window you can switch between Original Medicare and Medicare Advantage, change Medicare Advantage plans, or join or change a Part D drug plan. Changes take effect January 1.11Medicare.gov. When Does Medicare Coverage Start?
Working Past 65
If you are still working at 65 with a group health plan through an employer of 20 or more employees (yours or your spouse’s), you can safely delay Part B. In that arrangement the employer plan pays first and Medicare is secondary.12Centers for Medicare & Medicaid Services. MSP Employer Size Guidelines for GHP Arrangements – Part 1 When employment or the group coverage ends, you get an eight-month Special Enrollment Period to sign up for Part B with no penalty. The clock starts the month after employment or coverage ends, whichever comes first. COBRA and retiree health plans do not count as employer coverage for this purpose, so delaying Part B while on COBRA triggers a penalty.13Social Security Administration. Special Enrollment Period (SEP)
If your employer has fewer than 20 employees, Medicare is the primary payer from the start, and you should enroll in Part B during your Initial Enrollment Period even if you have employer coverage. Delaying will likely mean a penalty and a gap in primary coverage.12Centers for Medicare & Medicaid Services. MSP Employer Size Guidelines for GHP Arrangements – Part 1
The Penalties Are Permanent
Late enrollment penalties are not one-time fees. For every full 12-month period you could have had Part B but did not sign up, your premium goes up 10 percent, permanently. A two-year delay adds 20 percent to your monthly premium for the rest of your time on Medicare. Against the 2026 standard premium of $202.90, that is roughly $40.58 extra per month, forever.14Medicare.gov. Avoid Late Enrollment Penalties
Part D has its own penalty. If you go 63 consecutive days or more without Part D or other creditable drug coverage after your initial window closes, a surcharge is added to your Part D premium for as long as you have drug coverage. People who qualify for Extra Help are not charged the Part D penalty.15Centers for Medicare & Medicaid Services. The Part D Late Enrollment Penalty
Help Paying for Medicare in Louisiana
Many Louisiana residents qualify for both Medicare and Medicaid, making them dual-eligible. Medicare pays first for covered services, and Healthy Louisiana (the state Medicaid program, administered by the Louisiana Department of Health) picks up most of what remains: deductibles, copayments, and coinsurance. Healthy Louisiana also covers some things Medicare does not, including long-term care and comprehensive adult dental. Medicaid is needs-based, with financial eligibility criteria that differ from Medicare’s age- and disability-based rules.16Louisiana Department of Health. Healthy Louisiana
If your income is too high for full Medicaid but still limited, Louisiana runs three Medicare Savings Programs through the Department of Health:17Cornell Law School / Legal Information Institute. Louisiana Administrative Code Title 50, III-2325 – Medicare Savings Programs
- Qualified Medicare Beneficiary (QMB) pays your Part A and Part B premiums, deductibles, and coinsurance. It is the most comprehensive of the three.
- Specified Low-Income Medicare Beneficiary (SLMB) pays your Part B premium only.
- Qualifying Individual (QI) also pays your Part B premium only, at a slightly higher income limit than SLMB.
Louisiana does not apply an asset test for QMB, SLMB, or QI. Income limits are tied to percentages of the Federal Poverty Level and updated annually. Qualifying for any of the three also automatically qualifies you for Extra Help with Part D drug costs.
To apply for Medicare Part A and Part B, go through the Social Security Administration, online at ssa.gov, by phone, or at a local office; if you are already drawing Social Security benefits at 65, Part A and Part B enroll automatically. To apply for Healthy Louisiana or a Medicare Savings Program, go through the Louisiana Department of Health, either online through the Medicaid Self-Service Portal, in person, by mail, or by phone.18Louisiana Department of Health.
