Medicare AEP Starts October 15: Your Complete Charleston County Prep Guide

Medicare Annual Enrollment Period opens October 15 and closes December 7. That’s a 5-week window. In Charleston County this year, you’ll be looking at 47 Medicare Advantage plans, a pile of standalone Part D options, and a stack of mailers from carriers you’ve never heard of. Most people I meet start the process already overwhelmed. Then they make a rushed decision in late November, pick the plan with the flashiest mailer, and call me in March asking why their oncologist isn’t in network.

Let’s not do that this year.

Here’s the prep guide I give every Charleston County client before they sit down with me for a Blinco Audit. If you do this prep work in the two weeks between October 1 and October 15, you’ll walk into your enrollment meeting already halfway done. The decision gets clearer, the stress drops, and you keep more money in your pocket through 2027.

What’s Actually on the Table in Charleston County

Before we talk prep, let me tell you what you’re actually choosing between.

In Charleston County for the 2027 plan year, you’ve got 47 Medicare Advantage plans available across Humana, UnitedHealthcare (including the AARP-branded plans), Aetna, Wellcare, BlueCross BlueShield of South Carolina, Cigna, and a handful of smaller regional players. Some are HMOs, some are PPOs, some are Special Needs Plans for people with specific chronic conditions or dual Medicare/Medicaid eligibility.

The 47 number sounds absurd and honestly, it is. But when you strip out duplicates (same carrier, slightly different benefit tiers), plans that don’t include your doctors, and plans with prescription formularies that would break your budget on your specific medications, you’re usually down to 3-5 real contenders by the time we’ve done the work.

The 5-week window matters. Whatever you pick between October 15 and December 7 becomes your coverage starting January 1, 2027, and you’re locked into it until the Medicare Advantage Open Enrollment Period runs again from January 1 through March 31. That’s a long time to live with the wrong choice.

Step 1: Find Your ANOC Letter

Every Medicare Advantage and Part D plan is required by CMS to send you an Annual Notice of Change letter by September 30. That’s the letter that tells you what’s changing about YOUR current plan for 2027. Premium going up? Deductible changing? Your favorite pharmacy dropped out of network? It’s all in the ANOC.

If you’re in an existing plan, stop what you’re doing and go find this letter right now. It might be in the pile of Medicare mail on your counter. It might have a return envelope from Humana, UHC, Aetna, Wellcare, or BCBS. It might say “Important Plan Information” on the outside.

Read pages 1-3. That’s where the meaningful changes are. The rest is legal boilerplate.

If you can’t find your ANOC, call your current plan’s member services number (on the back of your insurance card) and ask them to re-send it. They legally have to.

If you don’t have a current plan because this is your first year on Medicare, skip this step - you’ll be starting from scratch.

Step 2: List Your Doctors and Specialists

Take a piece of paper. Write down every doctor you want to keep. I mean everybody:

• Primary care physician
• Cardiologist
• Oncologist
• Endocrinologist
• Orthopedist
• Dermatologist
• Gastroenterologist
• Ophthalmologist
• Neurologist
• Anyone else you’ve seen in the last 18 months

For each one, write down which hospital system they’re affiliated with. In Charleston County, most of them will be MUSC, Roper St. Francis, Trident Health, or East Cooper Medical Center. Some practices are independent and have privileges at multiple hospitals.

This list is going to do a lot of work for you. Medicare Advantage plans in Charleston County don’t all cover the same hospital networks. A plan that’s perfect for someone whose doctors are all at Roper might leave a MUSC patient with no specialists at all.

Step 3: List Your Medications

Every single prescription. Brand name, dosage, how often you take it. Don’t leave anything off, including the “just in case” rescue inhaler you use twice a year.

This is the part everyone underestimates. The price difference between two Medicare Advantage plans with comparable premiums can be $2,000-$4,000 a year depending on how each plan’s formulary treats your specific medications. One plan might have your blood thinner on Tier 2 with a $30 copay. Another might have the exact same drug on Tier 3 with a $95 copay. That’s $780 a year on one medication.

If you’re on Eliquis, Jardiance, Ozempic, Trulicity, Humira, or any of the big-name brand drugs that Medicare covers but charges for, this step isn’t optional. It’s the single biggest cost driver in the plan comparison.

Step 4: Figure Out How You Actually Use Healthcare

I ask every client this question, and the answer drives the Gold vs Silver vs Bronze equivalent decision for Medicare plans.

• Are you in good health, barely see doctors, and mostly need coverage “just in case”?
• Are you managing 2-3 chronic conditions with regular specialist visits?
• Are you in active treatment for something serious right now?
• Do you travel out of SC regularly and need coverage away from home?
• Are you expecting a major procedure in 2027?

There’s no wrong answer. But the answer changes which plan structure makes sense. An HMO-based Medicare Advantage plan might be great for someone who lives in Charleston full-time and uses Charleston doctors. It would be a disaster for a Snowbird who spends half the year in North Carolina.

A PPO plan costs more in premium but gives you more flexibility. A Special Needs Plan might save you thousands if you have diabetes and are willing to use a tighter network.

Step 5: Gather Your Costs From 2026

Dig out your Explanation of Benefits statements from 2026 if you can find them. Or just estimate. I want to know:

• How many primary care visits did you have?
• How many specialist visits?
• How many prescriptions did you fill, and what did you pay out of pocket?
• Did you have any hospital admissions or surgeries?
• Any imaging (MRI, CT, X-ray)?

This is gold when we’re comparing plans. A plan with a $0 premium and $50 primary care copay might cost you more than a plan with a $45 premium and $15 primary care copay if you see your primary care doc six times a year.

Step 6: Decide If You Want Extra Benefits

Medicare Advantage plans love to advertise their extras. Dental, vision, hearing aids, gym memberships, over-the-counter benefit cards, transportation to medical appointments, meal delivery after a hospital stay.

Some of it matters. Some of it is marketing fluff. A plan advertising $2,500 in dental benefits might only cover that amount with very specific in-network dentists, some of whom are booked 6 months out in Charleston County. A gym membership is nice if you’ll actually use it. An OTC card for $50 a month at Walgreens can genuinely offset grocery costs for folks on a fixed income.

Don’t pick a plan primarily because of extras. Pick it because the core coverage - doctors, hospitals, prescriptions - fits your life. Then see which of the contenders throws in extras you’d actually use.

What to Bring to Your Blinco Audit

When you sit down with me for your AEP appointment, whether it’s at my office in Summerville or over a Zoom call, bring these six things:

1. Your Medicare card. The red-white-blue one with your Medicare number on it
2. Your current plan ID card if you’re already enrolled in something
3. Your ANOC letter for your current plan
4. Your list of doctors and hospitals
5. Your full medication list with dosages
6. Any questions you’ve written down between now and the appointment

If we’re meeting virtually, email me these ahead of time or have them ready to share on screen. The 60-minute appointment moves fast once we have the raw material.

What the Blinco Audit Actually Does

When you hand me those six things, here’s what I do in real time with you watching:

Uncover. I open Medicare.gov’s Plan Finder with your exact zip code and medications loaded in. I’m not filtering to 47 plans. I’m filtering to the ones that pass your specific tests.

Decode. I show you exactly what each surviving plan costs you per month, per doctor visit, per prescription refill. I translate the Summary of Benefits into plain English. If a plan has a gotcha (and many do), I flag it.

Compare. We put the top 3-5 contenders side by side. I give you my honest opinion on which one I’d pick if I were in your shoes with your exact health profile, and why. You don’t have to take my opinion, but you’ll have it.

Protect. Once you’ve made the call, I enroll you. I confirm effective date. I make sure your primary care selection is correct if it’s an HMO. I give you my direct cell so you can text me in January if something weird happens with your new card.

That’s the full method. It takes about an hour if you’ve done the prep. It takes 90+ minutes if you haven’t.

Charleston County-Specific Things I Watch For

A few things that come up specifically because of where we live:

MUSC access. Not every plan treats MUSC the same way. Some include the full MUSC network with in-network specialists. Some treat MUSC as out-of-network for most providers, which can blow up your costs if you need specialty care. If you have a serious condition being managed at MUSC, this is a non-negotiable question I ask on every plan.

Roper St. Francis and Trident coverage. Same story. Which hospital system do your doctors use? A plan that’s strong on Roper and Trident but thin on MUSC might work fine for one client and be unusable for another a mile away.

Downtown Charleston vs. Summerville vs. Goose Creek. Charleston County has urban and suburban pockets, and Medicare plan network coverage varies. A plan that has strong specialist coverage in downtown Charleston might be thin on provider availability in Ladson or Lincolnville.

Snowbird and traveler considerations. Plenty of Charleston County seniors spend part of the year elsewhere - especially northern SC, NC mountains, Florida, or visiting family. Some MA plans have nationwide PPO networks. Some are local HMOs only. Know before you pick.

Don’t Pick Your Plan From a Mailer

This is the single biggest mistake I see in AEP. Somebody gets a glossy mailer from a carrier. It says $0 premium, $2,500 dental, free gym, transportation benefit. They call the 1-800 number on the mailer. A licensed agent somewhere in Arizona signs them up over the phone in 15 minutes without ever checking whether their cardiologist at MUSC is in network.

January comes. They show up at their cardiologist appointment. They’re told, “We don’t take that plan.” Now they’re stuck until the MA-OEP window in January-March, which only lets them make one switch. It’s a mess.

A mailer is marketing. It’s designed to make one plan look good. It’s not designed to help you find the right plan for YOUR doctors, YOUR medications, YOUR life.

The Clock Is Real

October 15 through December 7. Five weeks. After December 7, you’re locked in for most of 2027. You’ll get one more shot during MA-OEP (January 1 to March 31) to switch plans or drop back to Original Medicare, and that’s it.

The first week of AEP is always my busiest week of the year. By the last week of November, I’m completely booked. If you want the Blinco Audit experience - sitting down with someone who’s going to do the work with you instead of pushing you toward whatever plan pays the highest commission - reach out early.

Call me at (843) 594-1759 and let’s get your AEP prep meeting on the calendar for the second week of October. Do the six prep steps above between now and then and we’ll knock this out together. I don’t stop until you’re covered.

Frequently Asked Questions

When exactly is Medicare AEP in 2026? October 15, 2026 through December 7, 2026. Coverage from any changes you make starts January 1, 2027.

How many Medicare Advantage plans are available in Charleston County? For the 2027 plan year, about 47 Medicare Advantage plans are available in Charleston County across multiple carriers, plus standalone Part D options. The exact count shifts each year as carriers add and drop plans.

Can I switch Medicare Advantage plans outside AEP? Yes, during the Medicare Advantage Open Enrollment Period (January 1 - March 31) you can make one switch, either to a different MA plan or back to Original Medicare with a Part D plan. Outside of those windows, you generally need a Special Enrollment Period.

Do I need to do anything if I like my current Medicare plan? Probably yes. Read your ANOC letter to see what’s changing. Even “staying the same” plans often change premiums, formularies, and networks. I recommend every client do a Blinco Audit annually just to confirm the plan still fits.

Does it cost anything to use a Medicare broker? No. Medicare brokers are paid by the carriers, not by you. You pay the same plan premium whether you enroll directly or work with me. The difference is you get someone who has already vetted every plan against your specific doctors, medications, and budget.

What happens if I miss the December 7 deadline? You’re generally locked into your current plan (or Original Medicare if you don’t have an MA plan) for 2027. You may still have options during MA-OEP in January-March, or if you qualify for a Special Enrollment Period, but AEP is the main window.
