Imatinib mesylate is a generic drug that treats chronic myelogenous leukemia. Pharmacies can acquire a 30-day supply for about $96. Mark Cuban’s Cost Plus Drugs sold it for $47 as of 2023: manufacturer cost plus a flat 15% markup, a pharmacist fee, and shipping. Through a traditional pharmacy channel, the listed retail price for that same 30-day supply can exceed $10,000.
Between the factory and the patient sits a chain of companies, insurers, pharmacies, benefit managers, often all owned by the same parent corporation, each adding cost while making it harder to see what anything actually costs.
The imatinib gap is the whole system in miniature. The US pays more than any wealthy nation for worse outcomes, and a growing share of that excess flows not to doctors, hospitals, or drug manufacturers, but to the administrative machinery that sits between them.
US healthcare costs have broken away from peer countries
Every wealthy country has seen healthcare costs rise, but the US broke from the pack around 2000 and the gap has been widening ever since.
In 2022, the US spent $12,586 per person on healthcare. Japan spent $5,846. Even Switzerland, the second-most-expensive system, spent $2,000 less per person.
Despite record spending, Americans live shorter lives than people in every peer country
If the extra spending bought better health, it would be a defensible tradeoff. It doesn’t. The excess goes somewhere else.
American life expectancy was 78.0 years in 2022, while Japan reached 84.1, Switzerland 83.2, and Sweden 83.0. Japan’s gap is the starkest: $6,740 less per person per year, and 6.1 more years of life. The Commonwealth Fund’s Mirror Mirror report has ranked the US last among wealthy nations for health system performance three times running. The one category where the US scores near the top is clinical care process, the quality of treatment once a patient actually gets into the system. The problem is everything that happens before and after: the paperwork, the pricing, the billing, the layers of companies between the patient and the doctor.
Americans pay 50-250% more for the same drugs
The extra spending doesn’t buy better health. So where does it actually go? Start with the drugs.
Americans spent $1,713 per person on pharmaceuticals in 2023, 47% more than Germany ($1,168), 63% more than Canada ($1,052), and 2.4 times what Sweden paid ($713). The Netherlands spent even less at $485 per person. These countries aren’t buying inferior drugs. They’re buying many of the same branded medications at prices their governments negotiated down.
Most peer nations use centralized authorities to negotiate drug prices, and they can credibly threaten to exclude a drug from coverage if the price isn’t acceptable. The US has historically lacked that leverage. Medicare was legally prohibited from negotiating drug prices until the Inflation Reduction Act of 2022.
But negotiation is only part of the story. The deeper question is what happens between the factory and the patient, and why the same generic drug can cost 100 times more depending on which channel it flows through.
The drug pricing supply chain: where a $96 drug becomes $10,000
There’s a number that tells you what pharmacies actually pay to stock a drug. It’s called the National Average Drug Acquisition Cost, or NADAC, and it’s calculated from actual pharmacy invoices by the Centers for Medicare & Medicaid Services (CMS). Then there’s what patients actually pay. The gap between those two numbers is where the story lives.
The pharmacy acquires imatinib for $96 through distributors. Cost Plus sells it for $47 by buying direct from the manufacturer and skipping the distribution chain entirely. A patient walking into a traditional pharmacy without insurance can face a listed retail price over $10,000 for the same generic pill. Most insured patients pay less through copays, but the gap between acquisition cost and list price remains enormous. The branded version, Gleevec, was priced above $120,000 per year by the time its patent expired.
The pattern repeats across every drug in the table. How does a $96 drug become $10,000? Through a chain of intermediaries, each adding cost while obscuring the actual price.
Three companies control 80% of your prescriptions
The intermediaries with the most control over drug pricing are pharmacy benefit managers (PBMs). They sit between insurers, pharmacies, and drug manufacturers, theoretically negotiating lower prices on behalf of employers and health plans. In practice, the three largest have become vertically integrated conglomerates that profit from the complexity they were supposed to reduce.
Each parent company owns the insurer that decides coverage, the PBM that negotiates the price, and the pharmacy that fills the prescription. Together, these three conglomerates process about 80% of all prescription claims in the US, covering roughly 270 million people.
This raises an obvious question: if one company owns both the insurer and the pharmacy, why would it mark up the price on itself? Wouldn’t higher drug prices just mean higher insurance payouts?
They would, if the insurer were the one actually paying. In most cases, it isn’t. According to the Kaiser Family Foundation’s 2024 survey, 67% of covered workers are in “self-funded” plans, where the employer pays claims directly and the insurer just administers the paperwork. So when the parent company’s affiliated pharmacy marks up a drug, the insurance arm doesn’t absorb the cost. The employer’s health plan does. The parent company collects the markup at the pharmacy, collects a fee for administering the plan, and the employer writes the check.
For the remaining patients in traditional insurance plans, the mechanism is different but the result is similar. Plans increasingly use coinsurance, where a patient pays a percentage of the drug’s list price rather than a flat copay. A higher list price means a bigger coinsurance payment from the patient at the pharmacy counter, even if the insurer arm negotiates a “discount” that flows back to the same parent company.
The FTC’s 2025 report on PBMs quantified this. It examined 51 specialty generic drugs and found that the Big 3’s affiliated pharmacies generated more than $7.3 billion in revenue from dispensing these drugs above their acquisition costs between 2017 and 2022. The markup rate roughly doubled every two years over that period. These aren’t obscure drugs. They include generic versions of Gleevec (imatinib’s brand name), drugs for MS, transplant rejection, and kidney disease.
PBM advocates argue that rebate negotiations create pricing pressure that lowers net costs for plan sponsors. There’s some truth to this. But when the FTC examined the full picture, PBM-affiliated pharmacy markups on specialty generics far exceeded any rebate savings flowing to patients. The “savings” circulate within the same corporate parent, not back to the people paying copays.
When the government negotiates, prices drop 38-79%
The Inflation Reduction Act of 2022 gave Medicare the authority to negotiate drug prices for the first time. The first 10 drugs were announced in 2024, with negotiated prices taking effect in January 2026.
Januvia, a diabetes drug taken by 843,000 Medicare beneficiaries, dropped 89%, from $1,015 to $113 per 30-day supply. Eliquis, a blood thinner that cost Medicare $18.3 billion in 2023 alone, fell 73%, from $862 to $231. Jardiance, Xarelto, and Farxiga all dropped roughly 80%.
These 10 drugs accounted for $56.2 billion in Medicare Part D spending in 2023. CMS projects the negotiated prices will save Medicare $6 billion and beneficiaries $1.5 billion in out-of-pocket costs in 2026 alone. The program is expanding: 15 more drugs for 2027, another 15 for 2028, and 20 per year after that.
One round of negotiation on just 10 drugs saves $6 billion. Medicare covers thousands of drugs. And these discounts of 38-79% bring US prices closer to what every other developed country was already paying, without manufacturers operating at a loss.
The pharmaceutical industry’s strongest counterargument is that higher US prices subsidize R&D for the rest of the world. There’s something to this, but manufacturers set those prices themselves, and if global R&D genuinely needs cross-subsidization, concentrating the entire burden on one country is a strange way to structure it. The weaker objections are that Cost Plus only covers generics (not complex biologics) and that the “$10,000 retail price” is a list price most insured patients don’t pay in full. Both are true and both miss the point. Generic drugs account for 90% of prescriptions dispensed in the US. And list prices increasingly are what patients owe: coinsurance, where patients pay a percentage of the drug’s price rather than a flat copay, is now standard in many plans.
Drug pricing is the most visible part of the problem, but it’s only one layer. The same pattern, intermediaries extracting value while adding complexity, runs through the entire system. The US doesn’t just overpay for drugs and treatments. It overpays to manage the system that manages them.
The US spends $306 billion per year just to administer health insurance
Start with what it costs just to run the insurance system, before anyone sees a doctor.
The US spent $1,010 per person in 2022 on healthcare administration, more than double any peer country. Sweden spent $92, Japan $111, the UK $107. Even Germany, which has a complex multi-insurer system, spent only $370.
In absolute terms, the “Net Cost of Health Insurance” in the National Health Expenditure accounts reached $306 billion in 2024, the difference between what insurers collect in premiums and what they pay out in claims. That’s more than the country spent on dental care ($189 billion) or home health ($169 billion). This is the cost of operating a system where a single hospital might negotiate with dozens of insurers, each with its own billing codes, approval requirements, and payment rates.
Hospitals spent $43 billion in 2025 just getting paid
What happens between the insurer charging an employer’s health plan and the hospital actually receiving payment? According to the AHA’s 2026 Costs of Caring report: a lot of expensive friction. In 2025, hospitals spent $43 billion collecting payments that insurers owed for care already delivered, including $18 billion on claims denial appeals alone. The average hospital employs 64 dedicated billing and administrative staff, roughly 6.5% of its workforce, whose job is navigating the payment system rather than caring for patients.
Payment collection costs alone consumed about 2.6% of total hospital expenses in 2025. Factor in denial appeals ($18 billion), cybersecurity ($30 billion), and the broader administrative infrastructure, and hospitals are spending well over 8% of their budgets navigating the payment system rather than delivering care.
The CAQH (Council for Affordable Quality Healthcare) puts total administrative transaction costs across the industry at $83 billion a year. Providers shoulder 97% of those costs.
Deny first, sort it out later
The denial numbers tell a story of their own. A Health Affairs analysis cited in the AHA report found that Medicare Advantage plans denied 17% of initial claims submissions. Of those, 57% were ultimately overturned. The net effect: a 7% reduction in provider revenue from denials that stick, plus billions in friction costs from fighting the ones that don’t.
But the 17%/57% headline collapses at least three very different problems into one number. After this article was published, physicians across specialties described the denial loop from the inside in a discussion on r/medicine.
Documentation gaps. A large share of denials happen because the initial submission was incomplete or missing clinical context. The “appeal” is really just the first real submission with proper paperwork attached.
Automated rubber-stamps. In other cases, denials come back in minutes or seconds, with no sign that anyone actually read the file. The appeal that follows is a peer-to-peer phone call where a reviewing physician reads the ordering physician’s own clinical note back to them and approves it.
System intake failures. Sometimes payer intake systems simply fail to receive submitted documents, so the appeal is the only path that triggers human review at all.
All three show up as “denied, then overturned” in the aggregate data. They are not the same problem. Multiple physicians independently described Medicare Advantage and Medicaid managed-care plans as notably more adversarial than commercial payers in their denial practices, though that observation hasn’t been systematically measured.
CMS does track denials at the issuer level for ACA marketplace plans, through its Transparency in Coverage program. In 2023, marketplace insurers received 249 million claims and denied 42.4 million of them, a 17% aggregate denial rate. By 2025, that rate had climbed to 21%, with insurers denying 99.4 million of 474 million claims. The aggregate denial rate rose 3 percentage points in a single year (from 17.9% in 2024 to 21.0% in 2025), roughly 30 million additional denied claims. And the aggregate still flattens enormous variation between issuers. Among plans handling more than a million claims, some denied two or three times more often than others.
Look at Blue Care Network of Michigan: they deny 27.5% of claims, and when patients actually appeal, 88% of those denials get overturned. The insurer’s own review process agrees the claim should have been paid. That pattern only makes economic sense if most people never appeal.
By 2025, the leaderboard had shifted. The same UnitedHealth Group whose PBM conglomerate structure we described earlier now dominates the top of the denial chart through its marketplace insurance subsidiaries. Five of the seven highest-denial-rate issuers (among those processing over a million claims) are UnitedHealthcare entities, with rates between 35% and 49%. Combined, UHC’s marketplace plans denied 6.8 million claims at a 39% aggregate rate, nearly double the 21% marketplace average. Meanwhile, Ambetter of Magnolia, the worst performer in 2023 at 42%, dropped to 15%.
That’s the same parent company collecting pharmacy markups, administering self-funded employer plans, and now denying nearly two in five marketplace claims through its insurance subsidiaries.
And most people don’t appeal. Of the 42.4 million claims denied across marketplace plans in 2023, only 7.9 million internal appeals were filed, an 81% non-appeal rate. The high overturn rates would make routine denials a money-loser for payers if every denial were contested. But not every provider has the staff to fight, and not every patient has the energy.
The cost shift
The gap between what insurers charge and what hospitals actually receive is widened by structural forces on the government side. Medicare reimburses hospitals at 83 cents on the dollar, creating over $100 billion in underpayments in 2024 alone. That shortfall doesn’t disappear. It gets passed on to commercially insured patients, who pay higher prices to make up the difference.
Most of those patients are covered through the same self-funded employer plans described earlier, where the employer pays claims directly and the insurer just administers the paperwork. At large firms, 80% of covered workers are in self-funded plans.
Here’s where it gets strange. Self-funded plans are governed by ERISA, the federal Employee Retirement Income Security Act, which means they fall outside the jurisdiction of state insurance commissioners. If you have a traditional insurance plan and your insurer misses a payment deadline or refuses to explain a denial, you can escalate to a state regulator with enforcement power. If you’re in a self-funded plan, which most workers are, there is no comparable external authority. The appeals process ends with the plan administrator, typically the same entity that denied the claim.
More than half of hospital services lose money
More than half of all hospital service lines operate at a loss, and it’s largely those self-funded employer plans absorbing the shortfall. Together, these money-losing lines account for 56% of hospital costs.
Behavioral health reimburses at 74.5 cents on the dollar. Burns and wound care, infectious disease, trauma, obstetrics: all negative margin. These are the services hospitals can’t turn away. Hospitals cross-subsidize them from the few service lines that do generate positive margins, and that cross-subsidy comes from commercially insured patients, most of whom are covered by self-funded employer plans.
The opacity runs deeper than you’d expect. Several physicians in the r/medicine thread described being unable to see their own departments’ billing and reimbursement numbers. When a hospital negotiates with dozens of payers across dozens of plan types, there is no single price to optimize against. The complexity of the intermediary layer makes the system opaque even to the people inside it.
Hospital expenses grew 7.5% in 2025 while hospital prices grew only 3.3%. The gap between what hospitals spend and what they charge is narrowing. The intermediary layer, the billing, the denials, the administration, is what keeps expanding.
Where America’s $5 trillion in healthcare spending actually goes
Step back far enough and you can see all of these costs, the drug markups, the administrative overhead, the billing friction, in a single picture. In 2024, the United States spent $5.04 trillion on healthcare, more than the entire GDP of Japan.
Prescription drugs at $467 billion and insurance overhead at $306 billion jump out. And the $306 billion understates the real administrative burden, because it only counts the insurer side. It doesn’t include the $43 billion hospitals spend on payment collection, $18 billion on denial appeals, or the $83 billion in total admin transaction costs the CAQH estimates across all providers.
In 2000, the net cost of health insurance was $63 billion. By 2024, it reached $306 billion, a nearly five-fold increase that grew faster than every major clinical spending category.
The thread that connects every section of this article is the same: the excess doesn’t flow to the people providing care. It flows to the companies that sit between them and the patients.
The imatinib story is a miniature of the entire system. A product with a knowable, verifiable cost gets marked up through a chain of intermediaries, each with an incentive to keep prices opaque. The insurance industry takes $306 billion off the top before a single claim is paid. PBM-affiliated pharmacies generated $7.3 billion in excess revenue from just 51 specialty generics over five years. And when someone cuts through the chain, prices drop immediately.
The price-reduction math isn’t complicated. Cost Plus figured it out with a spreadsheet. Medicare negotiators got 38-79% off on the first try. Every other wealthy country has been doing it for decades. The interesting question is who benefits from pretending it’s complicated.
Updated April 20, 2026: The hospital-payment section has been updated to reflect physician perspectives shared on r/medicine after publication. Those observations are presented qualitatively throughout.
A note on the data
I started with the imatinib number because it’s almost unbelievable until you understand the mechanism. A $96 drug with a $10,000 list price sounds like a typo. It’s not. And the data to prove it, the NADAC, what pharmacies actually pay, is a public CMS dataset updated monthly. Nobody hides it. It just lives in a format that requires knowing it exists, knowing what it’s called, and being able to join it against retail price data from a completely different source.
That’s the pattern across the entire healthcare system. The FTC’s PBM report is public. The CMS National Health Expenditure data is public. The IRA negotiated prices are public. The OECD health statistics are public. None of it is secret. All of it is hard to work with, spread across agencies in incompatible formats, and most people who could use it spend their time wrestling with the data instead of asking questions about it.
OpenData is what I built to fix that. Every dataset in this article is queryable through a single API with consistent schemas. You can look up any drug by name, compare what Medicare paid versus what the IRA negotiated, or filter the NADAC by NDC code. No series code lookups, no Excel footnotes, no fixed-width files.
Every chart above links to its source data. If you disagree with a conclusion, you can run the same query and check.

Calculations & transformations: NADAC per-unit costs converted to 30-day supply costs using standard dosing regimens: imatinib 400mg = 1 tab/day x 30; celecoxib 200mg = 1 cap/day x 30; fingolimod 0.5mg = 1 cap/day x 30; abiraterone 250mg = 4 tabs/day x 30; enbrel 50mg/mL = 1 mL/week x 4. Drug price comparison chart uses log scale because the ratio between acquisition cost and retail price spans 2-3 orders of magnitude; linear scale would make the lower-cost bars invisible. IRA chart also uses log scale for the same reason.
Limitations: NADAC reflects average pharmacy acquisition costs and may differ from specific pharmacy costs. Cost Plus Drugs prices are mail-order only and exclude drugs requiring cold chain or specialty handling. “Traditional retail price” varies widely; we use average cash price estimates from GoodRx/SingleCare, which represent list prices before any insurance or coupon application. The FTC’s $7.3 billion figure covers specialty generics only (51 drugs, 882 NDCs, 2017-2022); the full scope of PBM markups across all drugs is unknown. IRA negotiated prices apply only to Medicare Part D beneficiaries and do not directly affect commercial insurance pricing. OECD PPP-adjusted comparisons embed price-level differences, meaning raw currency comparisons would show an even larger US gap.
