Medicare and diabetes in 2026: what supplies, insulin, and training cost in Delta County

Diabetes is the one condition where Medicare's split personality shows up most: your meter and your test strips are covered under Part B as equipment, your insulin is usually Part D, and your syringes are neither — unless you have a drug plan. Here's the whole map, with 2026 prices.

The short answer

In 2026, Medicare covers your blood sugar meter, test strips, lancets, continuous glucose monitor, and durable insulin pump under Part B as durable medical equipment — you pay 20% of the Medicare-approved amount after the $283 Part B deductible. Your insulin is capped at $35 for a one-month supply of each covered product, with no deductible, whether it comes through Part D or through a Part B-covered pump. But the injection supplies, the disposable patch pump itself, and non-insulin drugs like Ozempic sit outside that cap and run at your drug plan's regular cost sharing, protected only by the $2,100 annual out-of-pocket ceiling.

That's the whole structure. The rest of this article fills in the limits, the eligibility rules, the services that cost you nothing, and the four diabetes drugs whose Medicare-negotiated prices took effect on January 1. Every figure below links to Medicare.gov, CMS, or the CDC. This is education, not advice — and it is not medical advice.

Why Part B and Part D split your diabetes care

Almost every billing surprise in diabetes coverage traces back to one design decision made decades ago: Medicare classifies the tools of blood sugar management as medical equipment and the drugs as prescriptions, and those two things are paid for by two different parts of Medicare with two different sets of rules.

Part B — Medical Insurance — treats your meter, strips, lancets, CGM, and traditional insulin pump as durable medical equipment. DME has its own logic. Some items you rent, some you buy, and some become yours after a set number of rental payments. Your doctor has to prescribe the item for use in your home. And crucially, both the prescribing doctor and the supplier have to be enrolled in Medicare — if either isn't, Medicare won't pay the claim at all.

Part D — your drug plan — covers the insulin you inject yourself, the disposable pumps that aren't DME, inhaled insulin, oral diabetes drugs, and the medical supplies used for injections.

Two consequences follow, and both cost people money in this county specifically:

• The assignment question is not a formality. Medicare.gov's guidance is that a participating supplier must accept assignment, meaning it can charge you only the coinsurance and deductible on the Medicare-approved amount. A supplier that doesn't participate and won't accept assignment can charge more, with no cap. On rented equipment, Medicare.gov warns that unless the supplier accepts assignment for all rental months, you may have to pay the entire cost up front and wait for reimbursement. Ask before delivery, not after.
• Twenty percent of an ongoing supply is an ongoing bill. Original Medicare has no annual out-of-pocket maximum. A CGM with monthly sensors is not a one-time 20%; it's 20% every month, indefinitely. That is the single biggest reason a person managing diabetes on Original Medicare should look hard at whether a Medicare Supplement policy or a Medicare Advantage plan's out-of-pocket maximum fits their situation.

Every item, which part pays, and what it costs in 2026

This is the full map. "20% after the Part B deductible" means 20% of the Medicare-approved amount, once you've met the $283 annual Part B deductible for 2026, assuming your supplier accepts assignment.

Retrieved August 2026.

What insulin costs in 2026

Medicare.gov's language is precise, and the precision matters: "The cost of a one-month supply of each Part B- and Part D-covered insulin product is no more than $35, and you don't have to pay a deductible for insulin."

Unpack that sentence and you get four rules:

1. $35 is a ceiling, per product, per month. If you take a long-acting insulin and a mealtime insulin, that's two covered insulin products, and you can owe up to $35 for each. Some people pay less than $35; nobody with a covered insulin product should be paying more.
2. No deductible — on either side. Under Part D, the plan deductible does not apply to covered insulin. Under Part B, CMS states directly that "the Medicare Part B deductible does not apply for insulin used through a pump covered under the durable medical equipment benefit." Medicare Advantage plans likewise cannot apply a deductible to pump insulin.
3. A three-month fill is capped too. CMS: cost sharing must not exceed $70 for up to a two-month supply, or $105 for up to a three-month supply — that is, $35 for each month's supply of each covered insulin.
4. It applies to everyone with Part D, including people with Extra Help, and at both preferred and non-preferred pharmacies. People with full Extra Help already pay lower amounts and keep paying those lower amounts.

One more piece of good news for anyone on Original Medicare with a Medigap policy: Medicare.gov notes that if your Medicare Supplement policy pays your Part B coinsurance, it should cover the $35-or-less cost for your pump insulin.

And a footnote that quietly helps: CMS confirms the $35 or less you pay for a month's supply counts toward your true out-of-pocket costs — so it moves you toward the $2,100 annual cap even though it's a discounted amount.

What the $35 cap does not cover

This is the section that saves people the most money, because it's where expectations and reality diverge.

1. Non-insulin diabetes drugs. CMS names them explicitly: the cap "doesn't apply to prescription drugs, including injectable drugs, that are not insulin products" — and lists Trulicity, Bydureon BCise, Byetta, Mounjaro, Ozempic, Symlin, and Victoza as examples. These are Part D drugs at your plan's regular cost sharing. Your protection is the $2,100 annual cap, not a $35 monthly one.

2. The disposable patch pump itself. If you wear a small tubeless pump that gets changed every two or three days, the insulin going into it is capped at $35 under Part D. The pump is not. CMS explains that because the disposable pump is a piece of equipment rather than an insulin product, it isn't subject to the cap, may cost more than $35, and your plan deductible may apply. You also can't add it to your drug list in Medicare's Plan Finder, which means the tool won't show you that cost.

3. Injection supplies. Medicare.gov's wording on this is worth reading twice: "For insulin-related supplies (like syringes, needles, alcohol swabs and gauze), you'll pay all of the costs under Part B (unless you have Part D)." Part B does not cover these at all. This is one of the clearest reasons why someone on Original Medicare who injects insulin needs a drug plan even if their insulin itself is somehow otherwise handled.

4. Formulary placement can still change mid-year. CMS notes plans can change their formularies during the year for specific reasons — adding or removing drugs, moving a drug to a different cost-sharing level, swapping a brand for a generic. In general a plan must notify you at least 30 days before the cost or coverage of a drug you take changes. Read those letters.

The negotiated prices that started January 1

For the first time, Medicare has directly negotiated prices for a set of high-spending brand-name drugs that had no generic competition. The negotiated prices — the statute calls them Maximum Fair Prices — took effect on January 1, 2026. Of the 10 drugs in the first cycle, four treat diabetes.

Source: CMS — Negotiated prices for initial price applicability year 2026 — agreed negotiated price for a 30-day supply, calendar year 2026. Bars show the negotiated price; the table below shows the 2023 list price each was reduced from.

Source: CMS — Negotiated prices for initial price applicability year 2026. List prices are Wholesale Acquisition Costs for a 30-day supply based on calendar year 2022 prescription fills, rounded to the nearest dollar; enrollee counts are calendar year 2023 and rounded to the nearest thousand.

What this does and doesn't mean for your pharmacy counter. Two honest caveats. First, a negotiated price is the price in the system — it is not automatically your copay. What you pay still depends on your plan's cost sharing, your benefit phase, and whether you get Extra Help. For insulin specifically, the $35 monthly ceiling was already the binding number for most people. Second, the effect is real but indirect: by law, Medicare drug plans must include the selected drugs on their formularies, and CMS estimated people with Medicare drug coverage would save about $1.5 billion in 2026 under the projected standard benefit design.

The practical move is a phone call. Ask your plan what your 2026 cost sharing is for your specific diabetes drug now that the negotiated price is in effect, and get the answer before the Annual Enrollment Period opens on October 15.

Continuous glucose monitors: who qualifies

CGMs are the most-asked-about item in this whole category, and the eligibility rule is narrower than most people assume.

Medicare covers a continuous glucose monitor and related supplies like sensors under Part B's DME benefit if your doctor or other health care provider orders it and you meet both of these conditions:

• You take insulin, or you have a history of problems with low blood sugar (hypoglycemia).
• You or your caregiver have had enough training to use the monitor as directed.

Before ordering, your provider must evaluate you and confirm you're eligible. That evaluation is a documentation requirement, not a formality — it's what supports the claim.

Cost: 20% of the Medicare-approved amount after the $283 deductible, if your supplier accepts assignment. Because sensors are consumable, treat this as a recurring monthly cost when you're comparing coverage, not a one-time purchase.

The supplier question deserves one more mention here because CGMs are usually shipped rather than picked up locally. Medicare.gov's own instruction: ask a supplier whether they participate in Medicare and will accept assignment of your claims before you get the equipment. In a rural county where the nearest DME storefront may be in Grand Junction or Montrose, the supplier is often a mail-order company you've never dealt with — call and confirm.

How common diabetes is in Delta County

More common than anywhere else on our stretch of the Western Slope.

The CDC's PLACES program models small-area health estimates from national survey data. In its most recent release, 12.4% of Delta County adults reported having been told by a doctor that they have diabetes — roughly one in eight, and the highest crude rate among the six counties this agency serves. For comparison, Pitkin County sits at 8.4%.

Source: CDC — PLACES: Local Data for Better Health — "Diagnosed diabetes among adults," crude prevalence, 2023 model-based estimates from the 2025 PLACES release, retrieved via the Ambrose Insurance Brain in August 2026. PLACES figures are modeled small-area estimates with confidence intervals, not counts of diagnosed residents. Crude prevalence reflects a county's actual age mix; age-adjusted rates, which strip that out for cross-county comparison, are lower everywhere on this list.

Two related PLACES measures for Delta County put that number in context: 26.9% of adults have obesity and 37.5% have been told they have high blood pressure. Both are qualifying risk factors for Medicare's no-cost diabetes screening, which means a large share of the county's Medicare population is eligible for a screening they may not know they can get for nothing.

Why the crude rate is the relevant one here: Delta County skews older than the state, and crude prevalence reflects that. If you're 68 in Cedaredge or Hotchkiss and want to know how many of your neighbors are managing the same condition, the crude figure is the honest answer. If you want to know whether Delta County is inherently higher-risk after controlling for age, the age-adjusted figure is the one to use, and the gap between the two narrows considerably.

The no-cost services people skip

Medicare pays for three diabetes-related services at no cost to you if you qualify, and in our experience they are among the least-used benefits in the program.

Diabetes screening — up to 2 a year, $0

Part B covers up to 2 blood glucose lab screenings each year — fasting or non-fasting glucose tests, A1c tests, or other Medicare-approved glucose tests — if your provider determines you're at risk. You pay nothing if your provider accepts assignment.

You qualify with any one of: high blood pressure, a history of abnormal cholesterol and triglyceride levels, obesity, or a history of high blood sugar. Or with any two of: being 65 or older, being overweight, a family history of diabetes in a parent or sibling, or a history of gestational diabetes or delivering a baby over nine pounds. Note that being 65 or older is itself one of the second-list conditions — pair it with being overweight and you're eligible.

Medical nutrition therapy — 3 hours, then 2 a year, $0

If you have diabetes or kidney disease, or you've had a kidney transplant in the last 36 months, Medicare covers medical nutrition therapy at no cost to you when you qualify. That's an initial nutrition and lifestyle assessment, individual or group nutritional therapy, help managing the lifestyle factors that affect your diabetes, and follow-up visits.

Coverage is 3 hours in the first calendar year and up to 2 hours each calendar year after. The first-year hours don't carry over. You need a doctor's referral, and the provider has to be a registered dietitian or a nutrition professional meeting certain requirements. If your condition changes and your doctor decides your diet needs to change with it, they can refer you for additional hours beyond the initial coverage.

The Medicare Diabetes Prevention Program — for prediabetes, $0

This one is for people who don't have diabetes yet. It's a structured behavior-change program: 16 weekly core sessions in a group setting over six months with a trained coach, then 6 monthly follow-up sessions. You pay nothing if you qualify.

Eligibility is specific. Within the 12 months before your first core session you need one of: an A1c between 5.7% and 6.4%, a fasting plasma glucose of 110–125 mg/dL, or a 2-hour plasma glucose of 140–199 mg/dL on an oral glucose tolerance test. You also need a BMI of 25 or more (23 or more if you're Asian), and you must never have been diagnosed with type 1 or type 2 diabetes or End-Stage Renal Disease.

Suppliers can be traditional health care providers or community organizations — community centers, faith-based organizations. In a county without a large hospital system, that flexibility matters. Medicare.gov has a supplier search, and through December 31, 2029 you can take part in person, virtually through live online sessions, or a combination.

One discrepancy worth knowing about. Medicare.gov's coverage page currently states there is no limit to the number of times you can participate in the program, while the printed Medicare & You 2026 handbook describes it as a once-in-a-lifetime benefit. If you've completed the program before and want to do it again, confirm which applies to you by calling 1-800-MEDICARE or asking an approved supplier before you enroll.

The exception: self-management training is not free

Diabetes self-management training is labeled a preventive service, which leads people to assume it costs nothing. It doesn't. You pay 20% of the Medicare-approved amount after the Part B deductible. What you get is up to 10 hours of initial training — 1 hour individual and 9 hours group — plus up to 2 hours of follow-up training each calendar year after the year of your initial training. You need an order from your doctor. Exceptions to the group-session format apply if group sessions aren't available in your area, which is a real consideration in Delta County, or if your provider says you'd benefit more from individual sessions. It can also be delivered by telehealth.

Feet and eyes: the every-year, every-six-months rules

Diabetes complications concentrate in two places, and Medicare's coverage is built around specific intervals. Missing them is the most common way people lose a benefit they were entitled to.

• Diabetic retinopathy eye exam — once a year. Covered under Part B if you have diabetes, and it must be done by an eye doctor legally allowed to perform the test in Colorado. You pay 20% after the Part B deductible, plus a copayment in a hospital outpatient setting.
• Glaucoma screening — once every 12 months. Having diabetes is by itself a qualifying high-risk condition. Same 20% after the deductible. It must be done or supervised by an eye doctor legally allowed to do glaucoma tests in the state.
• Foot exam and treatment — every 6 months. This one has a narrower gate: Part B covers foot exams or treatment if you have diabetes-related lower leg nerve damage that increases the risk of limb loss — specifically, diabetic peripheral neuropathy with loss of protective sensation. Depending on your exam, care may include treatment for foot ulcers and calluses and toenail management. The six-month clock has a catch: it applies as long as you haven't seen a foot care professional for another reason in between.
• Therapeutic shoes and inserts — once a calendar year. You need diabetes plus severe diabetes-related foot disease, and the doctor treating your diabetes must certify the need. Each calendar year you can get either one pair of custom-molded shoes (if a foot deformity means you can't wear depth-inlay shoes) plus 2 more pairs of inserts, or one pair of extra-depth shoes plus 3 pairs of inserts. A podiatrist or other qualified doctor orders them, and you must get them from a podiatrist, orthotist, prosthetist, pedorthist, or another qualified individual — all enrolled in Medicare.

Worth flagging for anyone comparing plans: none of these four is free. All four run 20% after the Part B deductible under Original Medicare, and none of them counts toward the Part D drug cap, because they aren't drugs. Under Original Medicare alone there is no annual ceiling on that 20%.

How the $2,100 cap changes the math

For a person managing diabetes with multiple medications, the 2026 Part D structure is materially different from what it was a few years ago.

Here is how the year works. No Medicare drug plan may charge a deductible above $615 in 2026, and some plans have none. After the deductible you generally pay 25% coinsurance for generic and brand-name drugs until your out-of-pocket spending on covered Part D drugs reaches $2,100. At that point catastrophic coverage kicks in automatically and you pay nothing for covered Part D drugs for the rest of the calendar year.

Three implications for diabetes specifically:

• Insulin never triggers the deductible — it's exempt — but the $35 or less that you pay still counts toward your true out-of-pocket total, which pushes you toward the cap.
• Non-insulin drugs are where the cap earns its keep. If you take a GLP-1 or another high-cost brand-name diabetes drug, the $2,100 ceiling — not the $35 cap — is your protection.
• Part B costs sit entirely outside the cap. Your CGM sensors, strips, shoes, eye exams, and foot care are Part B. Nothing you pay there counts toward the $2,100, and Original Medicare puts no annual limit on that 20%. This is precisely the gap a Medicare Supplement policy or a Medicare Advantage plan's out-of-pocket maximum is designed to address.

If your drug costs are front-loaded — a common pattern when a deductible resets in January — Medicare also offers the option to spread your out-of-pocket drug costs in monthly payments across the year rather than paying at the pharmacy counter. We walk through the cap and that payment option in detail in our guide to the 2026 Part D out-of-pocket cap.

Does plan type change any of this?

The federal rules above describe what Medicare covers. How you're covered changes what you actually pay, and diabetes is a condition where that difference compounds month after month.

Original Medicare alone. You pay 20% of the Medicare-approved amount on all of the Part B items — CGM, sensors, strips, lancets, pump, shoes, eye exams, foot care — with no annual out-of-pocket maximum. For someone with a monthly sensor supply, that adds up predictably and indefinitely.

Original Medicare plus a Medicare Supplement (Medigap) policy. Medigap policies that cover Part B coinsurance pick up that 20%. Medicare.gov specifically notes that a Medigap policy paying your Part B coinsurance should cover the $35-or-less cost for pump insulin. The trade-off is a monthly premium and, outside your one-time Medigap Open Enrollment window, medical underwriting — which is exactly the kind of health history that can make a later switch difficult. We cover that window and the guaranteed-issue exceptions in our Medigap open enrollment guide.

Medicare Advantage. These plans must cover everything Original Medicare covers and have an annual out-of-pocket maximum, which caps your Part B-side exposure. Cost sharing for DME and supplies varies plan by plan, networks apply, and for the Medicare Diabetes Prevention Program Medicare.gov notes you may have to use an in-network provider. If you're weighing the two approaches, our Medigap vs Medicare Advantage comparison for Montrose and Delta counties lays out the structural differences.

If you have Medicare and Medicaid, or you qualify for Extra Help, your costs can be substantially lower than everything described above. Our guides to Dual-Eligible D-SNP plans in Delta County and the Part D Extra Help subsidy cover who qualifies and what it's worth.

A checklist before your next refill

1. Confirm you're not paying more than $35 a month for any covered insulin product. If you are, call your plan — the cap applies at preferred and non-preferred pharmacies alike.
2. Ask every DME supplier two questions before delivery: do you participate in Medicare, and will you accept assignment on my claims? For rentals, ask about every rental month.
3. Ask your plan what the negotiated prices did to your specific drug. Jardiance, Farxiga, Januvia, and NovoLog/Fiasp all have new 2026 prices in effect.
4. Book the eye exam. Once a year for diabetic retinopathy, plus a glaucoma screening every 12 months.
5. Ask about a foot exam if you have nerve damage in your lower legs — every 6 months, if you haven't seen a foot care professional for another reason.
6. Claim your therapeutic shoes if you qualify. The allowance resets each calendar year and does not roll over.
7. Get the referral for medical nutrition therapy. Three hours in your first year, at no cost to you if you qualify — and the hours don't carry over.
8. If you have prediabetes, ask about the Medicare Diabetes Prevention Program and check whether a supplier near you offers it in person or online.
9. Track your Part D out-of-pocket spending. Your Explanation of Benefits shows what counts toward the $2,100 cap and what phase you're in.
10. Get a free second opinion. Colorado's State Health Insurance Assistance Program, run through the Division of Insurance, offers one-on-one counseling at no cost and sells nothing.
