If you live in Yellowstone County and you’re trying to make sense of Medicare, here’s the thing nobody tells you: your options aren’t the same as your sister’s in another state, or even your friend’s one county over. Medicare plans are approved county by county. So let’s look at what’s actually available where you live.
One client put it to me this way: “Retiring is not for the weak.” They weren’t talking about money — they were talking about the paperwork. The good news: the Medicare piece has an order to it, and once you see the order, the overwhelm drops fast.
Whether you’re in Billings, Broadview, Laurel, or anywhere else in Yellowstone County, the numbers below are yours — Medicare sets plan availability county-wide.
Medicare Advantage in Yellowstone County: the 2026 numbers
- 26 Medicare Advantage plans are approved in Yellowstone County for 2026.
- 20 of them have a $0 monthly premium.
- 4 different insurance organizations offer plans here, including Humana, Blue Cross and Blue Shield of Montana, UnitedHealthcare, PacificSource Medicare.
- the highest 2026 overall CMS Star Rating in the county is 4.5 out of 5, and 6 plans are rated 4 out of 5 or higher.
- in-network out-of-pocket maximums range from $3,000 to $9,250, and premiums run from $0 to $202.10 per month.
- of the county’s 37,665 Medicare beneficiaries (CMS, 2026-March), 38% chose Medicare Advantage — the rest stayed on Original Medicare, most with a supplement and/or drug plan.
The number of plans isn’t the hard part. The hard part is that two plans with the same premium can treat the same prescription completely differently. That’s the detail that catches people.
HMO or PPO? What Yellowstone County actually offers
Of the 26 plans here, 5 are HMO-style and 21 are PPO-style. The difference matters more than most people realize. An HMO generally requires you to stay inside its network and often to get referrals — in exchange, costs are usually lower and more predictable. A PPO lets you see out-of-network doctors (at a higher cost), which matters if you split time between states, keep a specialist in another city, or just want the escape hatch.
Here is the question that actually decides it: if your cardiologist or your hospital dropped out of the network next year, how painful would that be? People with deep local roots and flexible doctor relationships often do fine in an HMO. People with established specialists — or a snowbird schedule — usually sleep better in a PPO.
How the plans here rate
CMS scores every Medicare Advantage plan on a 5-star scale using member complaints, care quality, and customer service. In Yellowstone County, 6 of the 26 plans carry a 2026 overall Star Rating of 4 out of 5 or higher, and the highest rating available in the county is 4.5 out of 5. A strong rating is a good sign — but it can’t tell you whether your doctors are in a plan’s network or your prescriptions are on its formulary. That check is personal, and it’s the single most important step before enrolling.
To see how the plans in the county rate side by side, search the plans at your zip code — or bring us your doctor and prescription list and we’ll do the checking with you.
What “$0 premium” really means in Yellowstone County
“I got a bill for $19,000.” A real sentence from a real call — from someone whose plan looked fine until it wasn’t. This is why the out-of-pocket maximum matters more than the premium:
20 of the county’s 26 plans charge no monthly premium — and that’s the number the TV ads shout. Here’s the number they don’t: the maximum out-of-pocket. In Yellowstone County it runs from $3,000 to $9,250 per year, with a median of $6,600. That’s the amount you could actually be responsible for in a bad health year, and the spread between plans is thousands of dollars.
Drug deductibles are just as uneven: others charge up to $615 before drug coverage kicks in. Same county, same $0 premium — very different first trip to the pharmacy in January.
The Part B Give-Back in Yellowstone County
Here’s a benefit most people first hear about from a TV commercial and assume is a scam: some Medicare Advantage plans include a Part B premium reduction — lowering what you’re responsible for paying toward your Part B premium each month. It’s real. In Yellowstone County, 9 plans include a reduction in 2026, and the largest available here is $100 per month. How it shows up depends on how you pay your premium, and processing can take a few months to start.
A larger reduction doesn’t automatically make a plan the better choice — networks, drug coverage, and out-of-pocket limits differ plan to plan and can outweigh the monthly amount. Ask us which reductions apply to your situation, or see the plans at your zip code.
Who’s on Medicare in Yellowstone County
37,665 people in Yellowstone County are enrolled in Medicare as of CMS’s 2026 March Monthly Enrollment data; 14,399 of them (38%) chose a Medicare Advantage plan while 23,266 stayed on Original Medicare. That split matters: it tells you roughly how your neighbors weighed the same decision you’re making — though the right answer is personal, not popular.
3,507 county residents qualify for both Medicare and Medicaid. The county has 4 Dual-Eligible Special Needs Plans (D-SNPs) built specifically for that situation — often with benefits regular plans don’t include, and most people who qualify have no idea they exist.
Dental, vision, and hearing in Yellowstone County plans
Original Medicare covers none of these — which surprises almost everyone. Among Yellowstone County’s Medicare Advantage plans: 26 include dental benefits, 26 include vision, and 26 include hearing coverage. The fine print varies enormously — annual maximums, in-network dentist availability, and whether “dental” means cleanings only or actual crowns and dentures. If dental work is on your horizon, this comparison alone can be worth hundreds of dollars a year.
Stand-alone drug coverage (Part D) in Montana
If you stay on Original Medicare — with or without a supplement — you’ll want a stand-alone Part D drug plan. Montana has 11 PDPs for 2026. Premiums run from $4.70 to $140.20 per month (median $29.70), and 4 plans price at or below the regional benchmark — meaning people who qualify for Extra Help can get them for $0.
A pattern worth knowing: the cheapest Part D premiums usually pair with the highest deductibles. The only way to know which drug plan is actually cheapest for you is to price your exact prescription list against each plan — that’s precisely what we do on a consultation call, and it takes about ten minutes. Or run the comparison yourself at your zip code.
When you can actually enroll
Availability means nothing if you miss your window. The three that matter for most people in Yellowstone County:
- Initial Enrollment Period — the 7 months around your 65th birthday (3 before your birthday month, your birthday month, 3 after). Missing it can mean permanent late-enrollment penalties on Part B and Part D.
- Annual Enrollment Period (Oct 15 – Dec 7) — when anyone can switch Medicare Advantage or Part D plans for the following year. This is when the plan numbers above get reshuffled — and when reviewing your plan against next year’s version actually pays.
- Still working past 65? If you have credible employer coverage, you may be able to delay Part B without penalty — but the rules are specific, and getting them wrong is one of the most expensive Medicare mistakes there is. This one is worth a conversation before your birthday, not after.
Questions people actually ask me — in their own words
“Can I start earlier?” Your Initial Enrollment Period opens 3 months before your 65th birthday month. Starting the homework 6 months out is the sweet spot — enough time to compare without deadline pressure.
“Even with Plan G?” Plan G covers most of what Original Medicare doesn’t — but it doesn’t include drug coverage, and it can’t be compared to an Advantage plan on premium alone. Different tools for different situations.
“Do I have to have Part B?” If you’re still working with credible employer coverage, maybe not yet — but the delay rules are specific, and getting them wrong triggers a lifetime penalty. This is the single most common question on my calls, and the answer is personal enough that I’d never answer it generically.
“This is such a racket.” I’ve heard that more than once, and I understand where it comes from — the mail, the commercials, the calls. Here’s my answer to it: real numbers from the government’s own plan file, and a conversation where I’ll tell you if staying put is your best move.
Quick answers for Yellowstone County
Do all 26 plans include drug coverage? No — 21 of them do. If you pick one of the others, you generally cannot add a stand-alone drug plan on top of it, which surprises a lot of people.
Is the biggest carrier automatically the best here? No. Humana offers the most plans in Yellowstone County, but plan count isn’t quality — the right plan depends on your doctors, your pharmacy, and your prescriptions, and it’s often not from the biggest name on the list.
Can I get help without being sold something? Yes. A consultation with me is a conversation, not a pitch — we look at your doctors, your prescriptions, and your timeline, and you leave knowing exactly where you stand. If a plan change doesn’t make sense for you, I’ll tell you that too.

Getting to know Yellowstone County
Yellowstone County covers about 2,633 square miles of Montana.
Most residents live in or around Billings, with Broadview, Laurel making up much of the rest. That works out to about 14 Medicare beneficiaries per square mile.
According to the CMS hospital registry, 2 Medicare-registered hospitals serve the county: Billings Clinic (Billings); Intermountain Health St Vincent Regional Hospital (Billings). 2 operate emergency services.
Why this matters for Medicare: every Medicare Advantage plan has a network, and the same hospital can be in-network on one plan and out on another. Knowing which facilities serve Yellowstone County is step one; checking how the plan you’re considering treats them is step two — and it’s exactly the kind of thing we verify on a consultation call.
Health context matters to plan choice, too. CDC county data shows about 10% of Yellowstone County adults live with diabetes and 32% with high blood pressure — a reminder that drug coverage and specialist networks deserve extra scrutiny here.
The broader health picture from the same CDC dataset: 27% with arthritis, 27% with depression among Yellowstone County adults. These aren’t just statistics — they map directly to what matters in a plan: tier placement of blood-pressure and antidepressant medications, physical-therapy coverage, and whether your specialists are in network.
For longer-term care, Medicare’s Care Compare registry lists 7 certified nursing homes in the county: St John’S Lutheran Home (Billings, 4-star CMS rating); Billings Rehabilitation And Nursing Llc (Billings, 2-star CMS rating); River Ridge Rehabilitation And Nursing Llc (Billings, 2-star CMS rating); Aspen Meadows Health And Rehabilitation Center (Billings, 2-star CMS rating), plus 3 more. (Facility ratings are CMS’s own 5-star quality ratings — worth knowing about even if you hope never to need them, because Original Medicare and Advantage plans cover skilled nursing stays differently.)
The county is also served by 4 Medicare-certified hospice providers — hospice care is covered under Part A regardless of whether you choose Original Medicare or Medicare Advantage, one of the few benefits that works the same either way.
A wider lens from CMS’s Geographic Variation data: Medicare spent about $10,205 per beneficiary in Yellowstone County in 2024 (standardized, so it’s comparable across regions); local beneficiaries made about 544 emergency-room visits per 1,000 people; and 15% of hospital stays led to a readmission within 30 days. Numbers like these shape what care access and costs actually look like where you live — and they’re part of why the same national plan can perform differently county to county.
How Yellowstone County compares to the rest of Montana
Averages hide the local picture, so here’s where Yellowstone County actually sits against the other 49 counties in Montana: 38% of Yellowstone County beneficiaries are in Medicare Advantage, well above the Montana median of 27%.
- Medicare spends $10,205 per beneficiary here — about the same as the statewide median of $9,974.
- Emergency-room use runs above the state median (544 visits per 1,000 beneficiaries vs. 501).
- You have 26 plans to choose from, well above the 13 a typical Montana county sees.
When most of your neighbours have already moved to Medicare Advantage, it’s usually because the local networks work well here. That’s a useful signal — but it doesn’t answer whether your doctors are in the plan you’re considering.
