Cash Price vs. Insurance: When Paying Cash for Medical Care Costs Less Than Using Your Plan
We compared hospitals' published cash prices against their insurer-negotiated rates. Insurance usually wins — but a colonoscopy at Houston Methodist is $519 cash vs $2,018 through a typical plan. How the deductible math works, and how your HSA can pay a cash price.
If you have a high-deductible health plan, the question “should I use my insurance or just pay cash?” has a real dollar answer — and it is hiding in the price file every U.S. hospital is required by federal law to publish. We compared the discounted cash (self-pay) price against the median insurer-negotiated rate for the same services at Cleveland Clinic Main Campus and Houston Methodist Hospital, using the hospitals' own published numbers. The short version: insurance usually wins — but when cash wins, it wins by thousands of dollars, and your deductible math can flip the answer either way.
Key Findings
- The median insurer rate beat the cash price in 27 of 31 comparisons. If your deductible is met, using insurance is almost always cheaper.
- When cash wins, it wins big. At Houston Methodist, the cash price for a diagnostic colonoscopy is $519 while the median insurer rate is $2,017.86 — paying cash costs 74% less. An upper endoscopy is $405 cash vs $1,968.02 — 79% less.
- Below your deductible you pay the insurer rate, not the cash rate. On a high-deductible plan that hasn't hit its deductible, that colonoscopy costs you the full negotiated rate (~$2,017.86) — roughly 4× what a self-pay patient would be quoted at the same hospital.
- Not every hospital plays. MD Anderson Cancer Center publishes no cash price at all — self-pay pricing there starts as a phone call, not a posted number.
Cash Price vs. Insurance Rate: The Same Service, Two Hospitals
For each CPT code, the hospital's published discounted cash price sits next to the median of the rates it negotiated with insurance plans. The cheaper of the two is bold. These are the hospitals' own numbers from their federally required price-transparency files — see our full three-hospital comparison for gross charges and methodology.

The bold value is the cheaper of the pair. The insurer median summarizes many plans — your plan's specific rate may be higher or lower. MD Anderson is excluded from this table because its file (dated 2026-07-01) publishes no cash prices.
The Deductible Math That Decides It
The cash-vs-insurance decision is not just “which number is smaller today.” It hinges on your deductible — in two directions.
- If you will meet your deductible this year anyway (ongoing treatment, planned surgery, a baby on the way), use insurance even when the cash price is lower. Cash payments made outside your plan usually do not count toward your deductible or out-of-pocket maximum, so a cash “saving” now can cost you the full deductible later.
- If you are unlikely to hit your deductible, compare the cash price against your plan's negotiated rate — because below the deductible, you pay that negotiated rate in full. Worked example from the table: a Houston Methodist diagnostic colonoscopy on a $3,000-deductible plan costs you ~$2,017.86 through insurance (the median negotiated rate, all yours below the deductible) vs $519 as a self-pay patient — cash saves ~$1,498.86 in a low-spend year.
The same arithmetic can point the other way at a different hospital — or even for a different service in the same building. Cleveland Clinic's cash price beats its insurer median on almost nothing; its negotiated rates are the better deal nearly across the board. There is no universal rule — only your hospital's two numbers.
Four Questions Before You Decide
- Will I hit my deductible this year? If clearly yes, run it through insurance. If clearly no, keep comparing.
- What is my plan's actual negotiated rate? Call your insurer or use their cost estimator — the hospital's file lists per-plan rates, and the median can hide a big spread.
- What is the hospital's cash price? Ask billing for the “self-pay” or “prompt-pay” price in writing. As a self-pay patient you are entitled to a Good Faith Estimate under the No Surprises Act.
- Am I giving anything up? Paying cash usually means the claim never reaches your insurer: no deductible credit, and the visit may not appear in your claims history. Some providers also require choosing one route up front.
Yes, Your HSA Can Pay the Cash Price
A common misconception is that Health Savings Account money can only be spent on claims processed through insurance. Not so: HSA funds can pay any qualified medical expense — including a cash-price bill you never submit to your plan. Paying a $519 cash colonoscopy from your HSA uses pre-tax dollars, which effectively discounts it again by your marginal tax rate. Keep the itemized receipt, and remember the expense still won't count toward your deductible.
How to Find a Hospital's Cash Price
Every hospital must publish its standard charges — gross, cash, and payer-negotiated — in a machine-readable file (45 CFR §180). The files are real but unfriendly: gigabytes of CSV or JSON, encoding quirks, and some hospitals (like MD Anderson) simply omit the cash column. Our price transparency guide walks through finding and reading them by hand. Or skip the spreadsheet: when you upload a bill from a hospital whose price file we've loaded, your analysis shows the hospital's own posted rates next to your actual charges.

Frequently Asked Questions
Is it cheaper to pay cash than use insurance?
Usually not — in our comparison of Cleveland Clinic and Houston Methodist price files, the median insurer-negotiated rate beat the published cash price in 27 of 31 services. But the exceptions are large: a diagnostic colonoscopy at Houston Methodist is $519 cash versus a $2,018 median insurer rate. If you haven't met a high deductible, always ask for both numbers.
Does paying cash count toward my deductible?
Usually not. When you pay a cash price, the claim typically never reaches your insurer, so nothing is credited toward your deductible or out-of-pocket maximum. If you expect heavy medical spending later in the year, running the service through insurance can be worth more than the upfront cash discount. A few insurers will credit self-pay receipts on request — ask yours before deciding.
Can I pay a cash price with my HSA?
Yes. HSA funds can pay any qualified medical expense, whether or not the claim goes through your insurance. Paying a hospital's cash price from your HSA uses pre-tax dollars, effectively discounting it again by your marginal tax rate. Keep the itemized receipt; the expense still won't count toward your deductible.
How much does a colonoscopy cost without insurance?
Per their own federally required price files, a diagnostic colonoscopy (CPT 45378) is $519 cash at Houston Methodist Hospital and $2,726 cash at Cleveland Clinic Main Campus — while their median insurer-negotiated rates are $2,018 and $984 respectively. Same procedure, opposite winners: at Houston Methodist cash costs 74% less than insurance; at Cleveland Clinic it costs almost triple.
How do I find a hospital's cash price?
Every U.S. hospital must publish a machine-readable file of standard charges, including its discounted cash price (45 CFR §180) — though some, like MD Anderson, omit cash prices entirely. In practice: ask the billing office for the self-pay price in writing, and request a Good Faith Estimate, which self-pay patients are entitled to under the No Surprises Act.
