Price transparency for medical billing remains a hot button issue across the country. A study from the Department of Health and Human Services Office of Inspector General in 2024 found that only 63 out of 100 hospitals surveyed were up-to-date with government price transparency requirements (1).
These unclear billing practices have real-world consequences for many Americans. Matt Rosenberg of New York recently took to Instagram Threads to describe how he combated out-of-control billing practices with a combination of his own financial literacy and using AI tools (2).
Here’s how he managed to get a $195,000 medical bill reduced to just $37,000.

‘Nobody should pay more out of pocket than Medicare would pay’
Rosenberg described how his brother-in-law died suddenly of a heart attack earlier this year. After helping his sister-in-law field smaller bills for the cardiologist and other specialists, the family was hit with the real cost: $195,000 for the hospital bill, with no transparency about the pricing and no standard CPT codes.
Rosenberg’s brother-in-law had allowed his health insurance to lapse some months before his death, and so the family was left to deal with the bills on their own. Feeling certain that the bill could be negotiated down, the family demanded the CPT codes, which took some time to receive. Rosenberg used Claude AI to analyze each code against the Medicare billing rules, and found that there were several major issues with the itemized charges, including double-billing for procedures (3).
Using the information from Claude AI, Rosenberg cross referenced the information using ChatGPT, and also did his own research to ensure the findings were accurate. He then used AI to write a letter outlining the billing violations he found and threatening legal action. The hospital capitulated and re-issued a bill to Rosenberg’s sister-in-law for $37,000.
“Ultimately, my big takeaway is that individuals on self-pay shouldn’t pay any more than an insurance company would pay — and which a hospital would accept as profitable business — than the largest medical payer in the country,” Rosenberg wrote.
“I had access to tools that helped me land on that number, but the moral issue is clear. Nobody should pay more out of pocket than Medicare would pay. No one.”

Medical billing: An ongoing controversy
At the end of his post, Rosenberg urged readers to speak up about unethical practices. “Americans: this doesn’t improve unless you make loud, constant, and discomforting noise to your representatives. We need a single payer health system in the U.S.”
His story not only highlights the urgent need for reform in health care billing practices, but also how average Americans should educate themselves about typical medical costs and the rules governing medical billing. For example, a study from 2015 found that the 50 most expensive hospitals in the U.S. at that time were charging up to 10 times their Medicare-allowable costs (4).
In Rosenberg’s case, his brother-in-law’s bill was several times the typical charges for heart attack treatment, with a recent study putting the average cost at $18,970 to $23,173 (5).
His story comes at a time when the Trump administration is enacting policy to weaken protections for those with medical debt. While several states have made moves to keep medical debt off of consumers’ credit reports, the rollback of these policies at the federal level could see those with medical debt struggle with their credit, including being unable to find housing, get a car loan, or even find employment (6).
How to challenge a hospital bill
As Rosenberg urged, Americans should research their medical bills to ensure the pricing is fair, and in alignment with the Medicare physician payment rates. If you have received a medical bill with unclear charges, don’t be afraid to ask for the CPT codes so that you can compare your charges with the Medicare standards. The Centers for Medicare & Medicaid Services (CMS) offer information on how to dispute a medical bill, with the reminder that you are entitled to dispute charges, and your costs won’t increase if you dispute a bill (7).
Whether you decide to use AI or not, the CMS offers the PFS Look-Up Tool so you can find Medicare payment information and related policies on over 10,000 common services (8).
What Americans should know about medical billing now
With Medicare payments set to rise for physicians in 2026 after several years of cuts, Americans should brace for higher bills across the board. However, any bills that don’t include a detailed, itemized list of CPT codes shouldn’t be accepted at face value — you have the right to ask for a properly itemized bill before you make any payments.
Remember that even those with a great deal of medical knowledge can get hit with unreasonable bills, as the recent story of Lauren Hughes proves. A physician herself, she was taken to an out-of-network hospital after a car accident with a broken ankle and some minor injuries — and was given a bill for $63,976.35 for her overnight stay.
As more stories like these circulate, growing calls for government-level reforms and a rise in AI-assisted consumer advocacy could create better transparency in medical billing — potentially spelling trouble for investors who have found heavy profits from ‘surprise billing’ practices.
Policymakers will also need to address the reasonable rates for medical care as more reports find unequal billing practices across hospitals and care providers in the current system. A recent analysis from the Kaiser Family Foundation on Transparency in Coverage (TiC) data hopes to open the “black box of health care pricing” so that everyone can see and compare prices across payers and providers for similar items and services (9).
For now, the 100 million Americans who owe medical debt will have to advocate for themselves, and look for ways to ensure their bills are fair and transparent.
“Debt is no longer just a bug in our system. It is one of the main products,” said Dr. Rishi Manchanda, former board member of the nonprofit RIP Medical Debt, in an interview with the Kaiser Family Foundation. “We have a health care system almost perfectly designed to create debt (10).”
