Medicare Open Enrollment can be one of the most confusing — and consequential — annual decisions for Lowcountry seniors. Every fall, between October 15 and December 7, Medicare beneficiaries have the opportunity to review their coverage, compare plans, and make changes that take effect January 1. The right choice can save thousands of dollars and ensure access to the doctors and hospitals you trust. The wrong choice — or no choice at all — can cost you dearly.
This guide cuts through the jargon and gives you a clear, practical framework for navigating Open Enrollment as a Summerville, Nexton, or Charleston area resident.
Understanding Medicare: The Basics
Before diving into Open Enrollment, here is a quick refresher on how Medicare works:
Part A: Hospital Insurance
Covers inpatient hospital stays, skilled nursing facility care, hospice care, and some home health care. Most people do not pay a premium for Part A if they or their spouse paid Medicare taxes for at least 10 years.
Part B: Medical Insurance
Covers doctor visits, outpatient care, preventive services, durable medical equipment, and some home health services. The standard Part B premium in 2026 is income-dependent and typically deducted from Social Security payments.
Part C: Medicare Advantage
Private insurance plans that combine Parts A and B (and often Part D) into a single plan. Offered by companies like UnitedHealthcare, Humana, Aetna, and BlueCross BlueShield. These plans often include extras like dental, vision, hearing, and fitness programs, but come with network restrictions.
Part D: Prescription Drug Coverage
Standalone drug plans that cover prescription medications. Available from private insurers. Plans vary significantly in which drugs are covered (the formulary), which pharmacies are in-network, and how much you pay at the counter.
Medigap (Supplement) Plans
Sold by private companies, Medigap policies cover some of the costs Original Medicare does not — like copayments, coinsurance, and deductibles. You can only have a Medigap policy if you are on Original Medicare (not Medicare Advantage).
What You Can Do During Open Enrollment (October 15 – December 7)
During this window, you can:
- Switch from Original Medicare to a Medicare Advantage plan (or vice versa)
- Switch from one Medicare Advantage plan to another
- Join a Medicare Part D drug plan
- Switch from one Part D plan to another
- Drop your Part D plan
Changes you make take effect January 1 of the following year.
Why Reviewing Your Plan Every Year Matters
Many seniors set up their Medicare plan once and never look at it again. This is a costly mistake because:
- Plan networks change annually. Your doctor may be in-network this year and out-of-network next year.
- Drug formularies change. A medication covered this year may not be covered — or may be covered at a higher tier — next year.
- Premiums and cost-sharing change. Copays, deductibles, and out-of-pocket maximums are adjusted annually.
- Your health needs change. A plan that was perfect three years ago may not be the right fit today.
- New plans enter the market. Better options may be available that were not offered last year.
Lowcountry-Specific Considerations
Provider Networks in the Charleston Area
Not all Medicare Advantage plans have the same hospital and doctor networks. In the Summerville and Nexton area, key considerations include:
- MUSC Health — one of the premier health systems in the Southeast. Not all Advantage plans include MUSC providers.
- Roper St. Francis — the parent system of Summerville Medical Center. Verify coverage before enrolling.
- Trident Medical Center — a major North Charleston facility. Check network status.
- Specialist access — if you see specialists at specific practices, verify they participate in any plan you are considering.
Pharmacy Access
Prescription drug plans (Part D) have preferred pharmacies where you pay the lowest copays. Check whether your local pharmacy — whether it is CVS, Walgreens, or an independent pharmacy in Summerville — is in the plan's preferred network.
Telehealth and Virtual Care
Post-pandemic, Medicare has expanded telehealth coverage. If you use virtual visits (increasingly common among retirees in Del Webb and other 55+ communities), verify that your plan covers telehealth at the same rate as in-person visits.
Common Open Enrollment Mistakes
1. Doing Nothing
Inertia is the most expensive mistake. Plans change every year, and the plan that was the best value last year may not be this year. Always review your options.
2. Choosing Based on Premium Alone
A $0 premium Advantage plan sounds great, but if it has high copays for the specialists you see or does not cover the drugs you take, it can cost far more than a plan with a modest monthly premium.
3. Not Checking the Drug Formulary
Before enrolling in any plan, check that ALL of your current medications are covered and at what tier. A drug moving from Tier 2 to Tier 3 can mean hundreds of dollars more per year.
4. Ignoring the Provider Network
Switching to an Advantage plan that does not include your primary care doctor, cardiologist, or oncologist means either paying out-of-network rates or changing doctors — neither of which is ideal.
5. Not Getting Professional Help
Medicare plan comparisons involve dozens of variables. A licensed broker can analyze your specific situation — medications, doctors, health conditions, budget — and narrow the field to the plans that actually make sense for you.
Working With a Local Medicare Broker
Michelle Blinco at Affordable Health and Dental is a nationally licensed health insurance broker based in the Summerville area who specializes in Medicare plan comparisons. She works with dozens of carriers and can:
- Review your current plan's upcoming changes
- Compare all available Medicare Advantage, Medigap, and Part D plans in Dorchester and Berkeley counties
- Verify your doctors and medications are covered
- Estimate your total annual cost under each option
- Enroll you in the plan you choose
There is no cost to you. Brokers are compensated by the insurance companies. Michelle's compensation is the same regardless of which plan you choose, so her recommendations are based on your needs, not her commission.
Coordinating Medicare With Your Financial Plan
Medicare decisions do not exist in a vacuum. They intersect with:
- Retirement income planning — your Medicare premiums are income-dependent (IRMAA surcharges apply above certain income thresholds)
- Social Security timing — Medicare premiums are typically deducted from Social Security benefits
- Tax planning — some medical expenses may be deductible, and HSA rules change once you enroll in Medicare
- Long-term care planning — Medicare does NOT cover long-term custodial care
Clark Williams at Edward Jones can help you understand how your Medicare choices fit into your broader financial picture. Coordinating health insurance decisions with retirement income strategies ensures you are optimizing both.
LB Dantzler, a State Farm agent and Chartered Financial Consultant, can also advise on supplemental insurance products — including long-term care insurance and life insurance — that complement your Medicare coverage.
