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.
