Transitioning to Medicare: Your Primary Option at 65
For most individuals in South Dakota, turning 65 means becoming eligible for Medicare. This federal program provides health coverage for people 65 or older, certain younger people with disabilities, and people with End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS). Medicare is structured into different parts:- Part A (Hospital Insurance): Covers inpatient hospital stays, skilled nursing facility care, hospice care, and some home health care. Most people don't pay a premium for Part A if they or their spouse paid Medicare taxes for a certain period while working.
- Part B (Medical Insurance): Covers certain doctors' services, outpatient care, medical supplies, and preventive services. Most people pay a monthly premium for Part B.
- Part C (Medicare Advantage): An alternative to Original Medicare (Parts A and B) offered by private companies approved by Medicare. These plans often include Part D (prescription drug coverage) and may offer extra benefits like vision, hearing, or dental.
- Part D (Prescription Drug Coverage): Helps cover the cost of prescription drugs. It's offered by private companies approved by Medicare.
Income and Eligibility for Bridge Coverage or Assistance
While Medicare becomes your primary option at 65, your income can still play a role, especially if you need bridge coverage before Medicare starts, or if you qualify for assistance with Medicare costs. For those under 65, or for a spouse under 65, ACA subsidies are based on household income relative to the Federal Poverty Level (FPL). For 2026, the Federal Poverty Level (FPL) for the 48 contiguous states and D.C. is a key benchmark for determining eligibility for ACA subsidies or South Dakota Medicaid:| Household Size | 100% FPL | 138% FPL | 150% FPL | 200% FPL | 250% FPL | 400% FPL |
|---|---|---|---|---|---|---|
| 1 person | $15,060 | $20,783 | $22,590 | $30,120 | $37,650 | $60,240 |

Once you are eligible for Medicare, you generally cannot receive federal subsidies (APTC) for an ACA marketplace plan. If you are already enrolled in an ACA plan and become Medicare eligible, you should cancel your marketplace plan to avoid potential tax issues. However, if your spouse is under 65 and needs coverage, they may still qualify for subsidies on an ACA plan.Health Plan Considerations Around Age 65
The best health plan strategy when approaching 65 depends on several factors, including your current coverage, employment status, and health needs. The following table outlines general recommendations:| Situation | FPL % (if applicable) | Recommended Path | Key Consideration |
|---|---|---|---|
| Not yet 65, need coverage | Below 138% FPL | South Dakota Medicaid | South Dakota expanded Medicaid; adults up to 138% FPL may qualify for $0-cost coverage. |
| Not yet 65, need coverage | 138% - 250% FPL | ACA Silver Plan with CSR | Substantial subsidies (APTC) and Cost-Sharing Reductions (CSR) make Silver plans highly affordable with lower deductibles/OOP maximums. |
| Not yet 65, need coverage | 250% - 400%+ FPL | ACA Gold, Silver, or HDHP | APTC helps reduce premiums; Gold for high expected use, HDHP+HSA for healthy individuals seeking tax advantages. |
| Turning 65, no employer coverage | N/A (Medicare eligible) | Enroll in Medicare Parts A & B | Enroll during your Initial Enrollment Period to avoid penalties. Consider Part C or D. |
| Turning 65, still working with employer coverage | N/A | Delay Part B, Enroll in Part A | You can often delay Part B enrollment if your employer coverage is "creditable." Enroll in Part A (usually free) at 65. |
| Need supplemental Medicare coverage | N/A | Medicare Advantage (Part C) or Medigap | Choose a plan that fits your budget and health needs to cover gaps in Original Medicare. |

The Critical Importance of Medicare Enrollment Periods
The most critical aspect of health insurance when turning 65 is understanding and adhering to Medicare's enrollment periods. Missing these deadlines can lead to permanent late enrollment penalties and gaps in coverage.- Initial Enrollment Period (IEP): This is your primary window to enroll in Medicare Parts A and B. It spans seven months: the three months before your 65th birthday month, your birthday month itself, and the three months after. For example, if your birthday is in July, your IEP runs from April 1st to October 31st. If you enroll during the first three months of your IEP, your coverage typically starts on the first day of your birthday month.
- General Enrollment Period (GEP): If you miss your IEP and don't qualify for a Special Enrollment Period, you can enroll during the GEP, which runs from January 1st to March 31st each year. However, coverage won't start until July 1st, and you may incur a late enrollment penalty for Part B.
- Special Enrollment Period (SEP): If you're still working at 65 and have group health coverage through an employer (or your spouse's employer), you might be able to delay enrolling in Part B without penalty. You'll then get an 8-month SEP to enroll in Part B that starts the month after your employment ends or the group health plan coverage ends, whichever comes first.
Health Insurance in South Dakota: What Seniors Need to Know
South Dakota utilizes the federal marketplace, HealthCare.gov, for individuals and families seeking ACA plans. For those under 65, or spouses under 65, the marketplace offers various plan types, including EPO, HMO, and PPO structures. South Dakota expanded Medicaid in 2023, meaning adults with incomes up to 138% of the Federal Poverty Level may qualify for comprehensive, low-cost coverage through the Medicaid expansion (approved by ballot measure, effective July 2023) program. This expansion also ensures that pregnant women and children in households up to 138% FPL are covered. For seniors, South Dakota's Medicaid program may also offer assistance through Medicare Savings Programs to help cover Medicare premiums and cost-sharing for those who meet specific income and asset limits.Enrollment Steps for Turning 65
Navigating the transition to Medicare and other health insurance options requires careful planning. Here are the steps to take:- Understand Your Medicare Initial Enrollment Period (IEP): Mark your calendar for the seven-month window around your 65th birthday. This is your primary time to enroll in Medicare Parts A and B.
- Assess Your Current Coverage: Determine if your current employer-sponsored health plan is "creditable" and if you can delay Medicare Part B enrollment without penalty. If you have an ACA plan, understand that subsidies will end once you're Medicare-eligible.
- Enroll in Medicare Parts A & B: If you don't have creditable employer coverage, enroll in Medicare Parts A and B during your IEP to avoid late enrollment penalties. You can do this through the Social Security Administration website.
- Consider Supplemental Coverage: Once enrolled in Original Medicare (Parts A & B), decide if a Medicare Advantage (Part C) plan or a Medigap (Medicare Supplement Insurance) plan, along with a Part D prescription drug plan, is right for you. These private plans help cover costs that Original Medicare doesn't.
- Seek Expert Guidance: If you're unsure about your options or the enrollment process, contact a licensed health insurance producer. They can provide free, unbiased advice on Medicare plans and any bridge coverage options available in South Dakota.
