Provider & Drug Check
Before you pick a plan, two checks matter most: are your doctors in the network, and are your prescriptions on the formulary? We do both — matching the Medicare plans we offer in the Sioux Falls area against your specific Sanford or Avera providers and your medication list, so there are no surprises after you enroll.
How to use this tool
Send us a short list: the doctors and clinics you want to keep (for example, your Sanford or Avera primary care and any specialists), and every prescription you take with its dosage. We check those against the plans we offer in your county and report back which ones keep your providers in-network and cover your drugs. There's nothing to install and no charge to have us run it.
What the numbers mean
Two things drive your real cost. Network status tells you whether a plan covers a provider at in-network rates or much higher out-of-network rates (or not at all on many HMOs). Formulary tier tells you how a plan prices each drug — lower tiers cost less, higher tiers more, and some drugs aren't covered at all. A plan with a low premium can still be expensive if your drug sits on a high tier or your doctor is out-of-network.
Why networks and formularies shift
Plan networks and drug formularies are set each year and can change at renewal — a doctor can leave a network, or a medication can move to a higher tier or drop off entirely. That's why a plan that fit last year may not this year. We re-check your providers and prescriptions against the current year's plans before you enroll, and again each fall, so your coverage keeps matching your actual care.
A quick note on these estimates
These tools give general estimates from publicly available CMS Plan Year 2026 data — they are not a quote, an enrollment, or a guarantee of coverage, cost, or eligibility. Plans, premiums, and rules change. Confirm current details with the plan and on Medicare.gov or 1-800-MEDICARE before you enroll, or let a licensed Big Sioux Benefits advisor verify your exact numbers for free.

Questions, answered
How do I know if my doctor takes a Medicare plan?
Networks change every year, so the safest answer isn't to guess — it's to verify. Send us your exact providers and we check them against each plan we offer before you enroll, free. We confirm whether your Sanford or Avera doctors are in-network at the plan's best rates so you're not surprised by an out-of-network bill later.
Will my prescriptions be covered before I enroll?
We can tell you ahead of time. Send your full medication list with dosages and we run it against each plan's formulary to see which cover your drugs and at what tier. Since tier placement drives your out-of-pocket cost far more than the premium does, this check often points to a very different best plan than price alone would suggest.
What if my doctor isn't in any plan's network?
It happens, and there are usually options. Some plan types, like PPOs, allow out-of-network care at a higher cost, and we can weigh whether that trade-off is worth it for you. We'll lay out which plans keep the most of your care in-network and what it would cost to keep a specific provider, so you can decide with the full picture.
Does it cost anything to have you check my doctors and drugs?
No. Running your providers and prescription list against the plans we offer is part of our free help — licensed agents are paid by the carriers, not by you. You get a clear answer on networks and drug coverage before you commit to anything, with no pressure to enroll in any particular plan.
What's the difference between in-network and out-of-network?
In-network providers have an agreement with your plan, so you pay the plan's lower negotiated rates. Out-of-network providers don't, which usually means higher costs — and on many HMO plans, non-emergency out-of-network care isn't covered at all. PPO plans do cover out-of-network care, just at a higher share. That's why we verify whether your specific doctors are in a plan's network before you enroll, so the rate you expect is the rate you get.
What is a formulary?
A formulary is a plan's list of covered prescription drugs, organized into tiers that determine your cost — lower tiers are cheaper, higher tiers more expensive, and some drugs may not be covered at all. Every plan builds its formulary differently, so the same medication can be inexpensive on one plan and costly on another. We run your full drug list against the formularies of the plans we offer to find your lowest total cost.
Can a plan drop my doctor or a drug during the year?
It can happen. Provider networks and drug formularies are generally set for the year but can change — a doctor may leave a network, or a drug can shift tiers or come off the list. Plans are required to give notice in many of these cases. This is one reason we re-check your providers and prescriptions each fall against the next year's plans, so your coverage keeps matching the care you actually use.
Do Medigap plans have provider networks?
No. Medigap (Medicare Supplement) plans have no network — any provider in the country that accepts Original Medicare accepts your Medigap coverage, because the plan simply pays your share after Medicare pays. That's a big advantage if you travel or want to use both the Sanford and Avera systems freely. Just remember Medigap doesn't include drug coverage, so you'd add a standalone Part D plan, which does use a formulary.
How can I find out if a specific drug is covered?
The most reliable way is to have us check it directly. Send us the drug name and dosage and we'll look it up on each plan's formulary, tell you which tier it's on, and estimate what you'd pay. You can also confirm current drug costs on Medicare.gov. Because tier placement affects your cost more than the premium does, checking your actual medications often points to a very different best plan.
What if I see doctors in both the Sanford and Avera systems?
That's common around Sioux Falls, and it matters a lot for plan choice, since a single network may include one system but not the other. If keeping both is important, we look closely at which plans we offer cover your specific doctors across both systems, or whether a plan with out-of-network flexibility makes more sense. We'd rather sort that out before you enroll than have you discover a gap in January.
