The price variation hiding inside your health plan

A recent Wall Street Journal analysis showed that Americans pay roughly four times what patients in peer countries pay for routine medical procedures. That gap is real and well documented. But the hospital pricing data now available under federal transparency mandates reveals something arguably more actionable: The price variation within a single American state is just as large as the gap between the United States and the rest of the developed world.

For more than five decades, researchers and policymakers have called for transparency in hospital pricing. The idea was simple: If patients, employers, and insurers could see what hospitals actually charge, the market could begin to function. In 2021, the federal government finally mandated that every hospital publish its negotiated rates in machine-readable files. The data is now public. It is updated regularly. And yet few in the employer benefits world appear to be using it.

I have spent the past year parsing these files for Georgia, including every hospital, every major commercial payer, procedure by procedure. What the data shows should change how benefits managers think about cost.

A five-fold spread for the same surgery

Take cesarean delivery, one of the most common inpatient procedures in the country. Across 39 Georgia hospitals with comparable commercial rates, the all-inclusive facility rate ranges from under $9,000 to nearly $44,000. Same procedure, same state, same clinical intervention, but a five-fold difference.

Georgia's median of about $15,000 sits almost exactly on the national figure, and Georgia is a good mirror of the rest of the country. But the variation within the state is enormous. These are not different procedures or different levels of care. They are simply different prices. And some of these differences exist within the same hospital system, where one campus can charge two to three times what another campus in the same system charges.

For a self-insured employer with 200 employees, three to five C-sections per year at the expensive end of the distribution instead of the median can mean $60,000 to $100,000 in excess facility costs for just one procedure.

The pattern holds across procedures

To test whether this was a quirk of one procedure, I ran the same analysis for colonoscopy with biopsy, one of the most common outpatient procedures. Across 35 Georgia hospitals, the facility fee ranges from under $900 to over $5,700 — a more than six-fold spread.

The colonoscopy data also permits a quality check. CMS publishes a measure called OP-32: the rate of unplanned hospital visits within seven days of a colonoscopy, capturing serious complications such as bleeding or perforation. Across Georgia hospitals, that quality score is essentially flat. Higher-priced hospitals do not have meaningfully fewer complications. The price variation is not buying better care.

What this means for employers

The federal transparency rule did not lower healthcare prices. But it did make the distribution of prices visible for the first time. For a benefits manager at a self-insured employer, three implications follow.

First, the biggest savings opportunity is not in negotiating lower rates across the board. It is in identifying the specific hospitals and procedures where your plan is paying at the top of the distribution and steering volume toward the middle or below.

Second, cost containment strategies that focus on per-employee-per-month averages are missing the point. What matters is variance: the spread between what your plan pays and what it could pay for the same service at a comparable facility.

Third, this data exists, it is public, and it is specific to your state and your payers. The five-decade wait for hospital price transparency is over. The question now is whether employers will use it.
