Diabetes and Medicare in Boise County, ID: 2027 Costs

Living with diabetes means a steady stream of small costs: test strips, a new sensor, insulin each month, a dietitian visit, a pair of shoes. Medicare covers a good share of that, but the share depends on the part of Medicare that pays and, for people in a Medicare Advantage plan, on the plan. This page reads the 2027 filings for the 14 Medicare Advantage plans sold in Boise County and the federal rules behind them, so you can see where your own diabetes costs would land before the December 7 deadline.

The Short Version: Key Takeaways

• Insulin is capped. A Part D plan cannot charge more than the lesser of $35, 25% of the Medicare negotiated price or 25% of the plan's negotiated price for a one-month fill of covered insulin, with no deductible (42 CFR 423.120(h)). All 9 Boise County plans with drug coverage attest to it for 2027.
• Monitors and supplies: all 14 plans file a $0 copay, but 10 limit them to specified manufacturers and 10 require authorization (CMS benefit files).
• Therapeutic shoes differ: $10 copays on 8 plans, 10% to 20% coinsurance on 6.
• Other diabetes drugs are not capped at $35. On the 2027 standard benefit, Januvia, Farxiga and Jardiance run about $873 to $1,132 a year.
• Boise County runs above the state average: 12.1% of adults have diagnosed diabetes against 10.1% for Idaho (CDC PLACES).

Diabetes in Boise County, in Numbers

The CDC's PLACES program estimates the share of adults with diagnosed diabetes in every county. For Boise County the 2023 release shows 12.1%, roughly 870 of the county's 7,188 adults. That is higher than 25 of Idaho's 44 counties, higher than the 10.1% state average and well above Ada County's 9%. These are model-based estimates, not a head count.

Diabetes tends to bring more visits, supplies and prescriptions, so a plan's cost sharing matters more than its premium. In a small county, the doctors, pharmacies and suppliers in the network matter as much as the benefit tables, so we check your own providers first. Our Boise County page has the county-wide plan picture.

What Original Medicare Covers for Diabetes

Original Medicare is the starting point, and every Medicare Advantage plan must cover at least what Part A and Part B cover (42 CFR 422.101). Part B generally pays 80 percent of the payment amount after the annual deductible (42 CFR 410.152 and 410.160). CMS has not yet published the 2027 Part B deductible, so we label it pending.

Sources: 42 CFR 410.18, 410.141, 410.132, 410.79 and 410.152(n) (Electronic Code of Federal Regulations, accessed November 12, 2026).

Notice what is missing: the monthly drug bill. Insulin and diabetes pills are Part D drugs, not Part B, so people with diabetes usually need a drug plan alongside Original Medicare, or a Medicare Advantage plan that includes one. Monitors and supplies are a separate group again, and that is where the plan filings give us real numbers.

Diabetes Supplies in the 14 Plans Sold in Boise County

CMS lists 14 Medicare Advantage plans for Boise County in 2027, not counting Special Needs Plans: 8 from Humana, 4 from Blue Cross of Idaho, 2 from UnitedHealthcare. 9 include drug coverage (CMS 2027 Landscape file). Here is what each filed for Medicare-covered diabetic monitors, supplies and therapeutic shoes or inserts.

Source: CMS CY2027 Plan Benefit Package, section 11c (pbp_b11), Boise County, accessed November 12, 2026. "Manufacturer limit" means the plan limits diabetic supplies to specified manufacturers.

Monitors and supplies are $0 at the copay level in every plan, but the last two columns matter. 10 of the 14 plans, the UnitedHealthcare and Humana ones, limit supplies to specified manufacturers, so your current meter and strips may or may not be on the list, and 10 require authorization. The 4 Blue Cross of Idaho plans file neither. The Humana filings list both a $0 copay and a 10% to 20% coinsurance for monitors and supplies, without saying which applies to which item or brand, so we read the Evidence of Coverage with you. Shoes and inserts run from a $10 copay on the 8 Humana plans to 20% coinsurance on most others.

Training, Nutrition and Prevention in the Plans

Diabetes self-management training teaches meal planning, medication timing, monitoring and what to do on a bad day. Part B covers it under 42 CFR 410.141, and Medicare Advantage plans must cover it too. What differs is cost sharing and referrals.

Source: CMS CY2027 Plan Benefit Package, section 14e (pbp_b14), Boise County, accessed November 12, 2026.

Every plan files the training with no cost sharing to you. The referral is the difference: 4 plans, all Blue Cross of Idaho, require one, so you would ask your doctor to send it before you book. Part B's own rule is that the treating physician or practitioner orders the training and signs a plan of care, so expect your doctor to be involved either way. Medical nutrition therapy follows a similar path: a physician referral and a registered dietitian or qualified nutrition professional (42 CFR 410.132).

If your blood tests are in the prediabetes range, the Medicare Diabetes Prevention Program offers structured sessions once in a lifetime, but only before a diabetes diagnosis. You need Part B, a qualifying BMI and blood test, and no end-stage renal disease (42 CFR 410.79). Ask us how your plan handles it before you rely on it.

Insulin: The $35 Rule for 2027

Insulin cost sharing is the clearest good news here. Under 42 CFR 423.120(h), a Part D plan must not apply a deductible to a covered insulin product, and your cost for each fill up to a one-month supply cannot exceed the lesser of three amounts: $35, 25 percent of the Medicare negotiated price for the insulin if it has one, or 25 percent of the plan's own negotiated price (42 CFR 423.100). A larger fill, such as 90 days, cannot cost more than the same days bought one month at a time. The limit applies in or out of network until you reach the annual out-of-pocket threshold, and every Boise County plan with drug coverage filed an attestation with CMS that it meets it for 2027.

Source: CMS CY2027 Plan Benefit Package, Part D file (pbp_mrx), Boise County, accessed November 12, 2026, matched to the CMS 2027 Landscape file drug-coverage flag.

The 5 plans without drug coverage need a standalone Part D plan, and the same insulin limit applies there (42 CFR 423.120(h)). Idaho has 8 standalone plans for 2027, with premiums from $5.30 to $238 a month (CMS Landscape file). The limit applies only to covered insulin products, so we check your exact product before you enroll.

Other Diabetes Drugs and What a Year Can Cost

Most non-insulin diabetes drugs are not capped at $35. Their cost depends on your plan's formulary tier and, on the standard benefit, on the $700 deductible and the 25 percent share. Three diabetes drugs have a Medicare negotiated price, which is what your plan pays before your share. The CMS price file lists 30-day prices for 2027, and CMS's negotiation page does not list any of the three among deselected drugs.

Sources: CMS Selected Drug List and Maximum Fair Price data file (September 21, 2026) and CMS CY2027 Rate Announcement ($700 deductible, 25% after it, $2,400 threshold). The yearly figure is our arithmetic, assuming no other drug costs and the standard benefit, not your plan's actual design.

The worked figures assume you pay 100 percent until the $700 deductible is met, then 25 percent. Real plans differ, and many use a flat brand copay. One more note: CMS's negotiation page lists NovoLog and Fiasp among drugs removed from the Selected Drug List effective January 1, 2027, so a negotiated price will not apply to them, but the insulin cost-sharing limit comes from a separate rule and still does.

Plans Built for People With Diabetes

Beyond the 14 plans above, Boise County has 7 Special Needs Plans in the CMS 2027 Landscape file. Three are chronic-condition plans (C-SNPs) that list diabetes, cardiovascular disorders and chronic heart failure as qualifying conditions.

Source: CMS CY2027 Medicare Advantage and Part D Landscape file (202610), Special Needs Plans, Boise County, accessed November 12, 2026.

These plans are built for people with a qualifying condition, and we confirm each plan's eligibility rules with the carrier. We have not read their benefit details, so we make no claim about their supplies or insulin costs. If you have diabetes, we compare them with the 14 standard plans and tell you plainly whether a C-SNP adds anything.

Questions to Ask Before You Pick

Every plan must give you an Evidence of Coverage and a Summary of Benefits (42 CFR 422.111), and we read them with you using these questions. A Medigap policy can also pay part of the 20 percent share Original Medicare leaves; see Medicare Advantage or Medigap in Boise County.

When You Can Change Plans

Source: 42 CFR 422.62, election of coverage under an MA plan, accessed November 12, 2026.

The enrollment period ends December 7, so if your supplies, insulin or doctors matter for 2027, compare now. Our answer on when you can change your Medicare plan covers the exceptions, and our dental, vision and hearing post covers the eye care that often comes with diabetes.

What to Watch This Fall

• Your Annual Notice of Change, sent each fall: look for changes to the supplies manufacturer list, the insulin tier and the out-of-pocket maximum.
• A plan that ended. Five Boise County Medicare Advantage plans from 2026 end for 2027 with no replacement plan (CMS crosswalk); if yours is one, you need a new plan by December 7.
• January 1 resets. The $700 deductible and $2,400 threshold start over, and CMS has not yet published the 2027 Part B premium and deductible, so we label them pending.

How We Built This Page

Plans come from the CMS CY2027 Landscape file for Boise County. Diabetes cost sharing comes from the CMS CY2027 Plan Benefit Package files (pbp-benefits-2027), sections 11c and 14e and the Part D insulin attestation, matched to Boise County through the plan service-area file. Prevalence comes from CDC PLACES, rules from the Electronic Code of Federal Regulations and drug prices from the CMS price file. The yearly drug costs are our own arithmetic.

Limits: we did not read each plan's Evidence of Coverage or check any plan's covered meters, sensors or insulin brands, so we make no claim about a particular product. Benefit amounts are as filed with CMS on November 12, 2026. This page is general education, not individual advice, and medication decisions stay between you and your doctor.
