Eliquis, Jardiance, and Insulin Cost $1,715 Without Extra Help vs. $437 With It: What Caregivers Need to Know Before December 7
A reader named Denise emailed me last week. She's not her neighbor Frank's daughter, niece, or power of attorney — she's just the woman down the hall who started driving him to appointments after his son moved out of state. Frank takes Eliquis for atrial fibrillation, Jardiance for his diabetes, and insulin. Denise had no idea what any of it cost, no access to his medical records, and seven weeks to figure out whether his Part D plan was still the right one before Open Enrollment closes on December 7.
This is happening more than most people realize. KFF Health News recently profiled this exact shift in "When a Friend Becomes a Caregiver" — older adults increasingly depend on neighbors, church friends, and former coworkers to help manage healthcare decisions, not just family. That matters for Part D specifically, because plan comparison doesn't require medical records. It requires three things: the drug list, the ZIP code, and the pharmacy. Denise had all three. She just didn't know where to start.
So let's start where she did: what Frank's three drugs actually cost, and why the number swings by more than a thousand dollars depending on one line on his Social Security file.
The Three Drugs, Two Very Different Bills
Frank's drug list is common — anticoagulant, SGLT2 diabetes drug, insulin. Under the Inflation Reduction Act's second round of Medicare drug price negotiations, both Eliquis and Jardiance now have federal Maximum Fair Prices that take effect in 2026, and insulin has carried a $35-per-month copay cap since 2023. But "the government negotiated a lower price" and "you personally pay less" are two different sentences, and the gap between them is where Extra Help (the Low-Income Subsidy, or LIS) does its work.
Here's what Pelandri's analysis of the plan-defaults and cms-marketplace-plans datasets shows for this exact three-drug combination, run against a standard 2026 Part D benefit design versus a full-subsidy Extra Help benefit:
| Cost Component | Standard Plan (No Extra Help) | Full Extra Help (LIS) |
|---|---|---|
| Monthly premium | $0 (benchmark plan) | $0 (benchmark plan) |
| Annual deductible | $615 | $0 (waived) |
| Eliquis (negotiated MFP $231/mo basis) | 25% coinsurance after deductible | $12.15 copay/month |
| Jardiance (negotiated MFP $47/mo) | 25% coinsurance after deductible | $12.15 copay/month |
| Insulin | $35/month cap (deductible-exempt) | $12.15/month cap (lower of the two applies) |
| Total annual out-of-pocket | ≈$1,715 | ≈$437 |
That's a $1,278 annual gap for the identical three drugs, same ZIP code, same pharmacy — the only variable is whether Frank is enrolled in Extra Help.
Why the Gap Is $1,278 — The Line-by-Line Math
On the standard plan, Frank's $615 deductible (the 2026 CMS-set maximum, per our plan-defaults dataset) applies first to the $3,336 combined negotiated cost of Eliquis and Jardiance for the year — insulin is exempt from the deductible under the IRA's insulin provisions. That leaves $2,721 subject to 25% coinsurance in the initial coverage phase, which comes to $680.25. Add the deductible and coinsurance together and Frank has paid $1,295.25 before a single insulin copay is counted. Insulin's $35-a-month cap adds another $420 for the year. Total: $1,715.25. He never reaches the $2,100 out-of-pocket threshold CMS has set for 2026 — the trigger for Medicare's zero-cost-sharing catastrophic phase — so he pays coinsurance on every fill, every month.
Under full Extra Help, none of that deductible or coinsurance math applies. LIS beneficiaries pay a flat, federally set copay per fill — $12.15 for brand-name drugs in the 2026 subsidy structure — regardless of formulary tier or coverage phase. Since that flat copay is lower than the $35 insulin cap, it applies to insulin too. Three drugs, three flat copays, twelve months: $437.40.
This is the kind of line-by-line breakdown Pelandri runs automatically for a specific drug list and ZIP code — you don't need to build this table yourself to know where you land on it.
The same mechanics show up across other drug combinations in this series. Our earlier breakdown of Xarelto and Farxiga found a similar structural gap, and the Gabapentin and Letrozole comparison landed on almost the identical $1,289 swing. This isn't a fluke of one drug list — it's how the Part D benefit design and the LIS copay schedule interact for nearly anyone on two or more brand-tier maintenance drugs.
The Fear Factor: Why Eligible Households Don't Apply
Here's the part that doesn't show up in a cost table. KFF Health News's reporting on immigrant families this month — "A Generation of Kids Suffer as Trump Destabilizes Immigrant Families" — documents something Area Agency on Aging counselors like me saw constantly in mixed-status households: a general reluctance to file any paperwork with a federal agency, even programs that have nothing to do with immigration status.
To be clear about the facts: Extra Help eligibility is determined through Social Security and IRS income data, and it is open to U.S. citizens and eligible immigrants who already qualify for Medicare. Applying for Extra Help does not trigger an immigration status review. But the KFF reporting is describing a real, documented chilling effect — households where one member fears any government contact pull back from programs the rest of the family is legally entitled to. If Frank lives with a grandchild whose immigration status is uncertain, or if Denise herself is hesitant to fill out any government form on his behalf, that hesitation has a dollar figure attached to it: $1,278 a year, for this drug list alone.
The corrective isn't political — it's informational. Extra Help applications go through Social Security's standard SSA-1020 form or state Medicaid offices, the same channel that processes Frank's retirement benefits. The eligibility test looks at income (roughly 150% of the Federal Poverty Level, adjusted annually) and limited assets. Nothing in that process touches immigration enforcement systems.
When Program Rules Shift Under Your Feet
There's a second lesson buried in this week's KFF coverage that applies directly to Part D planning. The piece on Medicaid work requirements — "Indigenous Groups Are Exempt From Medicaid Work Rules, but Native Hawaiians Aren't" — documents how the One Big Beautiful Bill Act's new work-requirement carve-outs apply unevenly across similar populations. Some Indigenous groups are exempted; Native Hawaiians, despite comparable employment and healthcare access barriers, are not.
The takeaway for Part D isn't about that specific policy fight — it's the pattern. Eligibility rules for federal health programs change from year to year, and exemptions and thresholds that applied to you (or to someone you're helping) last year may not apply this year, and vice versa. Extra Help income and asset limits are reset annually. A person who didn't qualify in 2024 might qualify in 2026 if their income dropped or the threshold rose. Someone who qualified last year could lose eligibility silently if their assets crossed the line — and their plan would revert to standard cost-sharing without anyone flagging it.
This is exactly why defaulting to "whatever plan I had last year" is the most expensive habit in Medicare. We've covered this mechanism before in the context of the December 7 Open Enrollment deadline — a plan that was optimal in 2025 can be $400-plus more expensive in 2026 purely because formulary tiers, deductibles, or subsidy status shifted underneath it.
The Caregiver's Checklist Before December 7
If you're in Denise's position — helping someone who isn't a spouse or a dependent, without full access to their financial picture — here's the sequence that actually works, drawn from two decades of sitting across a table from people in exactly this situation:
- Get the drug list, not the diagnosis. You don't need to know why Frank takes Eliquis. You need the drug name, dosage, and how many months' supply he fills at once.
- Ask if he's ever applied for Extra Help. Many eligible beneficiaries never apply simply because no one told them the form exists — this is separate from, and unrelated to, any immigration-related hesitancy.
- Confirm the preferred pharmacy. The same three drugs can cost differently at a preferred versus standard network pharmacy, and mail order sometimes beats both.
- Run the actual numbers for his ZIP code and formulary. Medicare Plan Finder lists more than 20 Part D options in most regions, and premium alone tells you almost nothing about the annual total.
- Do this again next year. Extra Help thresholds, IRA-negotiated prices, and formulary tiers all reset annually — last year's answer expires every October.
This is the exact workflow Pelandri was built to shortcut. You enter the drug list, dosage, ZIP code, and pharmacy preference once, and it runs the deductible, coinsurance, and cap math across every plan in the region — with or without Extra Help factored in — so a friend, neighbor, or adult child without medical authority can still get an accurate answer in minutes rather than building a spreadsheet from CMS formulary files.
Frank's $1,278 gap wasn't hiding in fine print. It was sitting in a form nobody had ever mentioned to him. Before December 7, that's worth five minutes to check — for your own drug list, or for whoever you're driving to appointments this year.
