If you live in Jefferson 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.
“I get so much mail.” I hear that sentence, almost word for word, on more calls than I can count. The stack of envelopes isn’t information — it’s marketing, and it’s designed to make this feel harder than it is.
Whether you’re in Edgewater, Golden, Lakeside, or anywhere else in Jefferson County, the numbers below are yours — Medicare sets plan availability county-wide.
Medicare Advantage in Jefferson County: the 2026 numbers
- 72 Medicare Advantage plans are approved in Jefferson County for 2026.
- 67 of them have a $0 monthly premium.
- 12 different insurance organizations offer plans here, including Humana, UnitedHealthcare, Aetna Medicare, Devoted Health.
- the highest 2026 overall CMS Star Rating in the county is 4.5 out of 5, and 37 plans are rated 4 out of 5 or higher.
- in-network out-of-pocket maximums range from $2,900 to $9,250, and premiums run from $0 to $177.50 per month.
- of the county’s 124,002 Medicare beneficiaries (CMS, 2026-March), 62% 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 Jefferson County actually offers
Of the 72 plans here, 48 are HMO-style and 24 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 Jefferson County, 37 of the 72 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 Jefferson County
“So we paid out our nose.” That’s how one client described the year their coverage didn’t match their health. The number that protects you from that year is the out-of-pocket maximum — and here’s the local spread:
67 of the county’s 72 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 Jefferson County it runs from $2,900 to $9,250 per year, with a median of $6,237.50. 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: 15 plans charge no drug deductible at all while 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 Jefferson 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 Jefferson County, 24 plans include a reduction in 2026, and the largest available here is $169 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 Jefferson County
124,002 people in Jefferson County are enrolled in Medicare as of CMS’s 2026 March Monthly Enrollment data; 76,914 of them (62%) chose a Medicare Advantage plan while 47,088 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.
9,987 county residents qualify for both Medicare and Medicaid. The county has 20 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 Jefferson County plans
Original Medicare covers none of these — which surprises almost everyone. Among Jefferson County’s Medicare Advantage plans: 72 include dental benefits, 72 include vision, and 72 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 Colorado
If you stay on Original Medicare — with or without a supplement — you’ll want a stand-alone Part D drug plan. Colorado has 10 PDPs for 2026. Premiums run from $0 to $151.90 per month (median $66.20), and 2 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 Jefferson 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
“Is drugs covered?” Only if your plan includes Part D coverage — 65 of 72 Medicare Advantage plans in Jefferson County do. If you go with Original Medicare plus a supplement, you’ll add a stand-alone drug plan.
“What is Part A and Part B, actually?” Part A is hospital coverage (usually premium-free), Part B is medical/doctor coverage (standard premium applies). Everything else — Advantage plans, supplements, drug plans — builds on top of those two.
“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.
“I have trust issues.” Someone said that to me flat-out on a call once, and honestly — good. You should. This industry earns skepticism. It’s why every number on this page comes from the official CMS plan file rather than my opinion, and why a consultation with me starts with your situation, not a pitch.
Quick answers for Jefferson County
Do all 72 plans include drug coverage? No — 65 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 Jefferson 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 Jefferson County
Jefferson County covers about 764 square miles of Colorado.
Most residents live in or around Edgewater, with Golden, Lakeside, Lakewood, Morrison, Mountain View making up much of the rest. At about 162 Medicare beneficiaries per square mile it’s one of the more densely settled parts of Colorado, which usually means more provider choice inside a single plan’s network.
According to the CMS hospital registry, 4 Medicare-registered hospitals serve the county: Lutheran Medical Center (Wheat Ridge); Centura Health-St Anthony Hospital (Lakewood); Orthocolorado Hosp At St Anthony Med Campus (Lakewood); Uchealth Broomfield Hospital (Broomfield). 4 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 Jefferson 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 8% of Jefferson County adults live with diabetes, 5% with coronary heart disease, and 5% with COPD. If you manage one of these conditions, it’s worth knowing the county has 4 Chronic-Condition Special Needs Plans — Medicare Advantage plans designed around specific conditions, with care coordination most standard plans don’t include. Whether one fits you is a network-and-medications question we can answer on a call.
The broader health picture from the same CDC dataset: 28% live with high blood pressure, 25% with arthritis, 23% with depression among Jefferson 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 23 certified nursing homes in the county: Edgewater Health And Rehabilitation (Lakewood, 5-star CMS rating); Western Hills Health Care Center (Lakewood, 5-star CMS rating); Ahc Of Lakewood, Llc (Lakewood, 5-star CMS rating); Villa Manor Care Center (Lakewood, 4-star CMS rating), plus 19 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 8 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 $11,678 per beneficiary in Jefferson County in 2024 (standardized, so it’s comparable across regions); local beneficiaries made about 501 emergency-room visits per 1,000 people; and 16% 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 Jefferson County compares to the rest of Colorado
Averages hide the local picture, so here’s where Jefferson County actually sits against the other 63 counties in Colorado: 62% of Jefferson County beneficiaries are in Medicare Advantage, well above the Colorado median of 40%.
- Medicare spends $11,678 per beneficiary here — above the statewide median of $10,701.
- You have 72 plans to choose from, well above the 21 a typical Colorado county sees.
- 8% qualify for both Medicare and Medicaid, well below the state median of 12%.
Higher-than-average local spending usually reflects how much care people here actually use — which is exactly why the out-of-pocket maximum on a plan matters more in Jefferson County than the monthly premium does.
