Turning 65 With a Marketplace Plan: Medicare Guide
HealthCare.gov is direct about it: a Marketplace plan "doesn't end automatically when Medicare starts," but your premium tax credit savings stop the month you become eligible for premium-free Part A, not the month you enroll. The IRS's own current instructions for Form 8962 confirm Medicare Part A counts as minimum essential coverage, which generally cuts off the credit for that month whether or not you've signed Medicare paperwork. Worse, a Marketplace plan doesn't open a Part B Special Enrollment Period the way job-based coverage does; Social Security's own internal policy manual documents a one-time relief program for people who made this exact mistake, but it only covers enrollment windows through June 30, 2020. Using Medicare.gov's own 2026 numbers, missing the window has a real price: the standard $202.90 Part B premium plus a 10%-per-12-months penalty for life. Here's the full guide: what actually happens to your Marketplace plan, the 7-month Initial Enrollment Period mapped out, four edge cases (a spouse under 65, working past 65, missing the window, automatic enrollment), and exactly how to cancel the Marketplace plan without a gap or a tax surprise.

Medigap Premium Increases in South Dakota 2027
CMS and the NAIC's own March 2026 guide to choosing a Medigap policy shows a textbook attained-age premium climbing from $120 a month at 65 to $126 at 66 — a roughly 5% jump in a single year, just for getting older. South Dakota doesn't require insurers to price Medigap any particular way: unlike Minnesota, which mandates community-rated pricing by law, South Dakota leaves the choice between community-rated, issue-age-rated, and attained-age-rated pricing up to each of the 41 Medicare Supplement companies licensed and actively marketing in the state as of May 2025, per the SD Division of Insurance's own company list. What the state does require, under SDCL 58-17-4.1, 58-17-4.2, and 58-17A-11, is that every rate change be filed with and approved by the Division of Insurance and meet a minimum loss ratio — real oversight, but no cap on how high an attained-age premium can climb as you get older. Here's the full guide: the three legal pricing methods explained in CMS's own worked dollar examples, what a decade or two of attained-age increases can look like, the guaranteed issue rights that still let you switch without medical underwriting, and what to actually do the next time a renewal letter lands in your mailbox.

Does Medicare Advantage Cover Dental Implants? Sioux Falls 2026
Medicare.gov is direct about it: Original Medicare generally doesn't cover dental implants or dentures, full stop. Medicare Advantage ads fill that gap with promises of a dental benefit, and per KFF's 2026 Medicare Advantage analysis, 98% of enrollees are in a plan with some dental coverage — but that figure blends a plan that pays for two cleanings a year with one that pays for real restorative work. We checked one real example ourselves: Align ChoicePlus (PPO), a $0-premium Medicare Advantage plan sold in Minnehaha County for 2026, caps its "Comprehensive Dental Services" benefit — fillings, root canals, gum treatment — at $750 a year, confirmed in both its own 2026 Summary of Benefits and Member Handbook. Dentures and dental implants don't appear anywhere on the plan's list of covered procedure codes, and the handbook says so directly: when implants aren't covered, even the crown that sits on top of one isn't covered either. With 15.2% of U.S. seniors 65 and older having lost all their natural teeth, per NIDCR, this isn't a rare gap. Here's the full guide: what a dental benefit actually promises versus what it pays, a worked example of what $750 actually buys, the real Minnehaha County plan landscape, and exactly how to check any plan's dental coverage before you enroll.

Wellmark Leaving Iowa Medicare Advantage for 2027: Sioux County Guide
The Iowa Insurance Division announced on October 15, 2026 that more than 87,000 Iowa Medicare beneficiaries, out of more than 700,000 statewide, were notified their current plan is being canceled or discontinued for 2027, as Wellmark and Medica both cancel their Medicare Advantage PPOs and take Mayo Clinic in-network access with them statewide. We checked CMS's own CY2026 and CY2027 Medicare Advantage Landscape files county by county to see exactly what changed at home: Sioux County (Sioux Center, Rock Valley, Orange City, Hull) goes from 16 non-SNP plans to 15, with $0-premium options falling from 11 to 7, while Lyon County goes from 19 plans to 13, with $0-premium options falling from 14 to 5. Wellmark's Blue Medicare Advantage Valor PPO is the one plan that disappeared outright in both counties, matching its parallel exit from all 43 South Dakota counties where it sold in 2026 and the broader non-renewal wave already reshaping Minnesota's market. Here's the full plan-by-plan breakdown for both counties, what the Mayo Clinic network loss actually means if you've never used it, the guaranteed-issue Medigap right it opens if you move to Original Medicare, and the December 7, December 31, and February 28 dates that protect you.

Minnesota Medicare Advantage Changes for 2027: A Siouxland Guide
MPR News reported on October 16, 2026 that nearly 390,000 Minnesotans received notices this month that their current Medicare Advantage plan is being discontinued for 2027 — out of more than 1 million Minnesotans on Medicare, per the same report. Blue Cross and Blue Shield of Minnesota's president and CEO, Dana Erickson, told MPR News the carrier has lost more than $500 million on Medicare over the past three years, the reason it gave for cutting most of its Medicare Advantage plans; Humana confirmed to the same outlet it had fewer than 10,000 Minnesota members last year and is exiting the state's individual Medicare Advantage market for 2027. Nationally, CMS's own September 28, 2026 press release projects the weighted-average Medicare Advantage premium will fall 16.5%, from $14.37 a month in 2026 to $12.00 in 2027 — a real number that can mask a very different local picture, as Minnesota shows. If your plan is among those non-renewing, you get a Special Enrollment Period from December 8 through the last day of February, on top of the standard October 15–December 7 Annual Enrollment Period. Here's the full guide for Luverne, Pipestone, and Worthington: what's actually happening and why, what a Part D coverage gap costs using Medicare's own penalty formula, how South Dakota's own 2027 non-renewals compare, and the Minnesota Medigap guaranteed-issue window worth knowing about before you decide.

Medicare Hold-Harmless 2027: South Dakota Guide
The Social Security Administration announced a 3.6% cost-of-living adjustment for 2027 on October 14, 2026, averaging about $75 a month more starting in January, per the agency's own press release. For most people on Medicare, a federal rule called hold-harmless keeps a Part B premium increase from shrinking that raise, since it blocks the premium from cutting your net Social Security check below last December's amount. The 2026 Medicare Trustees Report currently projects the 2027 Part B premium at $209.50, up $6.60 from the confirmed 2026 premium of $202.90, per CMS's own Table V.E2. But hold-harmless has four real blind spots, confirmed independently by a Congressional Research Service report and a KFF issue brief: anyone who pays an income-related surcharge (IRMAA, roughly 8% of Part B enrollees per CMS), anyone whose premium is paid by Medicaid, anyone not collecting Social Security, and anyone newly enrolling in Part B this year. None of them get the rule's floor under their check. Here's the full guide: what the rule actually does, the math behind this year's raise, two worked South Dakota examples, the full 2026 IRMAA bracket table, and how to check your own status before CMS's real number lands in mid-November.
Read →Medicare Hospital at Home: Sioux Falls 2026 Coverage Guide
Avera McKennan's Hospital@Home program has cared for 570 patients and saved 1,193 hospital bed-days in Sioux Falls since its 2022 pilot, per an August 2025 report from Avera Health. It works through a federal waiver, Acute Hospital Care at Home, that CMS launched in November 2020 and that Congress let nearly lapse five separate times since 2022 before the Consolidated Appropriations Act, 2026, signed February 3, 2026, finally extended it through September 30, 2030, per the current codified text of 42 U.S.C. §1395cc-7(a)(1). Because a Hospital@Home stay is billed under the same inpatient prospective payment system as a hospital bed, per CMS's own December 2024 program review, the same Medicare Part A inpatient deductible applies, not a separate fee. CMS's own outcomes data shows lower 30-day readmission rates for Sioux Falls's two most common treated conditions, pneumonia and COPD, and lower 30-day post-discharge Medicare spending across most of the top diagnosis groups studied, though readmissions ran higher at home for respiratory infections and sepsis. Here's the full guide: what the program actually is, who qualifies, what a day of care looks like, the waiver's bumpy five-extension history, and the one detail about your Medicare Advantage plan worth confirming before you ever need this.

Medicare Star Ratings for 2027: What Sioux Falls Should Know
CMS published the real 2027 Medicare Advantage and Part D Star Ratings on October 8, 2026, one week before this year's Annual Enrollment Period opened — and two of Sioux Falls's standard Medicare Advantage plans just crossed into bonus-payment territory. Per CMS's own October 8 Summary Ratings data table, both Aetna Medicare (contract H1608) and Align powered by Sanford Health Plan (contract H8385) rose from a 3.5-star to a 4-star overall rating for 2027, the threshold where a plan starts qualifying for a federal Quality Bonus Payment. The UnitedHealthcare Dual-Eligible Special Needs Plan contract held at 4.5 stars. Nationally, CMS's own fact sheet reports 37% of MA-PD contracts (188 of 508 rated) earned 4+ stars for 2027, covering 71% of enrollment, while the enrollment-weighted average overall rating slipped slightly from 4.01 to 3.99 and the count of 5-star contracts fell from 22 to 15 — none of them in South Dakota. This update (originally published September 5, 2026) also covers CMS's Contract Year 2027 final rule removing 11 ratings measures, the Clover Health lawsuit and the litigation it triggered, the Quality Bonus Program's $13.4 billion price tag, and how to actually use a star rating before December 7.
Read →Your $90 Medicare Payment: Who Got It, Who Didn't, and What It Means for Your 2027 Plan Choice
Starting in early October 2026, CMS sent a one-time $90 payment to more than 20 million Original Medicare Part B enrollees, drawn from the Medicare Improvement Fund — a $2 billion pool Congress created in 2008 that, per the White House's own fact sheet, had never before been used for a direct beneficiary payment. Roughly 35 million Medicare Advantage enrollees were not eligible, along with anyone whose premium is paid by Medicaid or who pays an IRMAA surcharge, per KFF's independent analysis. Applying South Dakota's statewide 36% Medicare Advantage penetration rate (KFF) to Minnehaha County's 39,532 Medicare beneficiaries suggests roughly 14,232 county residents were excluded on Advantage status alone. The $90 covers about 44% of one month's 2026 Part B premium ($202.90) — and KFF projects the 2027 premium will rise by roughly $79, eating most of it back. CMS's own CY2027 Advance Notice, independently confirmed by MedPAC, shows the standard Part D deductible rising from $615 to $700 and the Part D out-of-pocket cap rising from $2,100 to $2,400. Here's the full guide: what the payment actually is, exactly who qualified, why Medicare Advantage was excluded, the real South Dakota numbers, the 2020 precedent worth knowing, and what to actually do before December 7.
Read →Does Medicare Cover the New Alzheimer's Blood Test? South Dakota's 2026 Coverage Reality
The FDA cleared the first blood test for diagnosing Alzheimer's disease, the Lumipulse G pTau217/β-Amyloid 1-42 Plasma Ratio, on May 16, 2025, for adults 55 and older with signs or symptoms of cognitive decline — but CMS has no National Coverage Determination for the billing codes involved, and Noridian, South Dakota's own Medicare contractor (Jurisdiction JF), has no Local Coverage Determination for them either, per a Medicare Advantage payer's own coverage table citing CMS's own listings, current as of October 17, 2025. In the FDA's own 499-sample study, 91.7% of positive results and 97.3% of negative results matched PET scan or spinal fluid confirmation. A bill in Congress, the ASAP Act (H.R. 6130), would add Medicare coverage for tests like this one starting January 1, 2028 at the earliest — but it hasn't passed. South Dakota carries the nation's 2nd-highest Alzheimer's death rate, and 16,500 South Dakotans 65 and older, 10.5% of that age group, are living with the disease today, per the Alzheimer's Association's 2026 South Dakota facts sheet. Here's the full guide: what the test actually is, why FDA clearance isn't the same as Medicare coverage, how this differs from the PET scan or spinal fluid test already used for the Alzheimer's drugs Leqembi and Kisunla, what's pending in Congress, and what a South Dakota family can do right now.
Read →A Medicare Advantage Grievance Isn't an Appeal. Here's the Difference, and What to File.
A grievance challenges how a Medicare Advantage plan or its providers treated you; an appeal challenges a coverage or payment decision — and CMS's own grievance page says a grievance is anything 'other than an organization determination,' which means it can never reverse a denial. You generally have 60 days to file a grievance and your plan must respond within 30 days (with a possible 14-day extension), per that same CMS page, while a Level 1 appeal runs on a separate 65-day filing deadline, per Medicare.gov. One detail that's gone stale in a lot of guidance, including some of our own: as of May 1, 2026, the outside reviewer for Part C appeals changed from Maximus Federal Services to C2C Innovative Solutions, Inc., confirmed directly from CMS's own appeals-and-grievances page. If a plan's own process still doesn't fix a conduct problem, South Dakota residents can take it to the state Division of Insurance at 605.773.3563 — but only after the carrier's own internal appeal process is exhausted, per the Division's own complaint page. Here's the full guide: the exact CMS definitions, the grievance clock laid out day by day, how to file, what changed with the Independent Review Entity in 2026, when you need to file both a grievance and an appeal, and every route a South Dakotan actually has when a plan won't make it right.
Read →Should You and Your Spouse Have the Same Medicare Plan? A Sioux Falls Guide for 2027
Medicare has no couples or family plans, per Medicare.gov, so each spouse picks their own Part D, Medicare Advantage, or Medigap coverage. For plan year 2027, CMS's own landscape file lists 9 stand-alone Part D plans in South Dakota, with monthly premiums from $5.30 to $222.90, down from 11 plans in 2026. The 2027 Part D out-of-pocket cap is $2,400 per person, up from $2,100, and the standard deductible rises from $615 to $700, per CMS's CY 2027 Rate Announcement, so two spouses with heavy drug costs face a combined $4,800 ceiling. Putting a spouse with few prescriptions on the highest-premium plan instead of the lowest costs $2,611.20 more in 2027 premiums alone. Couples still tend to match: a 2024 JAMA study of 2010 to 2018 data found 83.8% of Medicare Advantage enrollees started the year in the same plan as their partner. Here's the full guide: the complete 2027 South Dakota Part D list, the six Minnehaha County Medicare Advantage plans with drug coverage, per-person MOOP and Medigap rules, when matching really does make sense, and how to run each spouse's drug list before December 7.
