Should You Use Your Insurance — or Pay Cash?
Your insurance card is not always your cheapest way to pay. Hospitals publish two very different prices for the same procedure: the rates they negotiated with insurers, and a cash price for patients who pay out of pocket. Those two numbers often have little to do with each other. About 3 in 10 times, the cash price wins.
We checked our own database: 106,267 published prices where hospitals listed both a cash price and insurer-negotiated rates for the same procedure. In 30% of them, the cash price was lower than the median negotiated rate. For the 15 procedures hospitals report most often, it was 26%. Researchers at Johns Hopkins found the same pattern nationally, with cash prices often coming in below what insurers negotiated. As researcher Ge Bai put it to KFF Health News, "we can very confidently say this is very common."
When this matters most
It matters when you pay the full price yourself, which is exactly what a high-deductible plan makes you do. About a third of covered workers are in high-deductible plans, and the average single deductible is now $1,886, according to KFF's 2025 employer survey. Until you hit that number, you pay the insurer's negotiated rate out of pocket. If the hospital's cash price is lower than that rate, your insurance is costing you money.
Once you've met your deductible, the math flips: you pay only your copay or coinsurance, and cash rarely beats that.
How to do it
- Ask for the cash price BEFORE you hand over your insurance card. Say: "What is your cash price for this procedure?" Once the visit is billed to insurance, the cash option is usually gone.
- Find out what you'd actually pay with insurance. Check your plan's portal or call the number on your card: have you met your deductible, and what is the negotiated rate for this procedure at this hospital?
- Compare the two numbers, then factor in the deductible. Cash payments do not count toward your deductible or out-of-pocket maximum. If you're close to hitting your deductible, running it through insurance can be smarter even when cash is cheaper today.
- Get the cash price in writing before the procedure, with the procedure code on it.
- Uninsured? You have a federal right to a Good Faith Estimate of the cost before scheduled care. Ask for it in writing. Details at cms.gov/nosurprises.
It also helps to know the going rate before you call: look up the procedure on Patients Price — for example, colonoscopy or MRI brain — to see what hospitals report charging, cash and negotiated side by side.
Three honest caveats
- The hospital's cash price usually covers the facility only. The surgeon, anesthesiologist, or radiologist may bill separately. Ask whether their fees are included before you agree to anything.
- About 7 in 10 times in our data, the negotiated rate beat cash. This is a check-first tactic, not a rule. Never assume.
- You generally can't pay cash and then bill your insurance for the same service later. Decide before the visit, not after the bill arrives.
If the number you get still feels wrong, the rest of this section has your back: check the bill line by line and negotiate what's left.
Before your next appointment, make one call: "What is your cash price for this procedure?" Then compare it to what your plan would charge you. It takes five minutes. In our data, the cash price wins about 3 times in 10.
