When you compare a surgical quote from one country with a quote from another, you are also comparing two ways of deciding a price. Some systems pay a fixed amount for a whole hospital stay. Others price each service from a government schedule. Some let each hospital set its own list price and negotiate from there. Medical-tourism providers mostly sell packages they design themselves. Knowing which mechanism produced a number tells you what it probably covers and how far it can move.
Key takeaways
- A case rate (the DRG model) prices a whole inpatient stay as one unit. Medicare's version multiplies a DRG weight by a wage-adjusted base rate and adds set adjustments.
- A fee schedule prices each service with a formula. Medicare's anesthesia payment, base units plus time units times a local factor, is a clear example.
- Colombia publishes a regulated tariff manual in UVB units. It is mandatory for traffic accidents and catastrophic events, and for urgent care when the parties have no agreement. It is not the price list for foreign self-pay patients.
- Market-set packages, such as UK private self-pay prices, can vary by thousands within one country. Hip-replacement averages in PHIN's March 2026 data range from £13,847 to £17,540 by city.
Mechanism 1: the case rate
Under Medicare's inpatient prospective payment system, an acute-care hospital receives a set amount per inpatient stay rather than a payment for each service. Each stay is assigned to a diagnosis-related group (DRG) with a relative weight that reflects average resource use. That weight is multiplied by a base rate whose labor share is adjusted by the local wage index. Add-ons follow for hospitals serving many low-income patients, for teaching hospitals and for unusually costly outlier cases (CMS, 2026).
For a patient reading a quote, the key feature is the unit. A case rate prices the stay, not the line items. If a quote abroad says "hospital package, three nights," it is behaving like a case rate. Your questions are what defines the case and what happens when your stay falls outside it.
Mechanism 2: the fee schedule
A fee schedule prices individual services with a published formula. Medicare's anesthesia payment shows the logic in one line: base units for the procedure plus billed minutes divided by 15, multiplied by a conversion factor that differs by locality. In 2026 that factor is, for example, $21.26 per unit for Los Angeles and Orange counties (Noridian Medicare, 2026, USD). Fee schedules make prices predictable for the payer that sets them. They do not bind every other payer, which is why the same US service can carry several different "prices" at once. Our Medicare rate benchmark explains how to use those schedules as a yardstick.
Mechanism 3: regulated tariffs, the Colombian example
Colombia shows how a regulated tariff can sit alongside a negotiated market. The Ministry of Health updates the tariff annex of Decreto 780 de 2016, now expressed in UVB (unidad de valor básico). Law 2294 of 2023 created the UVB and adjusts it each year for inflation (MinSalud Circular Externa 025, December 2024).
The circular is precise about scope. The tariffs are mandatory for care after traffic accidents, natural disasters, terrorist attacks and other catastrophic events. They also apply to other urgent care when the payer and the provider have no agreement. Two 2025 entries show the scale: a hematocrit test (code 19505) at 0.566 UVB, or COP 6,500, and an electrophysiological study (code 25101) at 210.55 UVB, or COP 2,432,200 (MinSalud, 2024).
The phrase "when the parties have no agreement" is the clue for a foreign patient. Outside the regulated situations, prices are set by agreement between payers and providers. A self-pay visitor buying elective surgery is buying a package the provider designs. The tariff manual is a useful sign that a service has a regulated reference value. It is not the number on your quote.
Mechanism 4: market-set packages
In a market-priced system, each hospital names its own self-pay price. The UK private sector is the best-documented example, because the Private Healthcare Information Network publishes average package prices. Its March 2026 collection reports average self-pay hip replacement packages of £13,847 in Glasgow, £15,712 in London and £17,540 in Cambridge (PHIN, March 2026 data, GBP). That is a spread of roughly £3,700 for the same operation inside one country. PHIN also calls these figures a guide only. They cover city centres and the surrounding 25 miles, and it asks patients to get each hospital's inclusions confirmed in writing.
Medical-tourism packages are market prices too, usually without a public average. Spread between providers in one city can easily exceed the gap between countries, so a country-level average is a starting point at best.
The four mechanisms side by side
| Mechanism | Who sets it | Unit being priced | Documented example | What it means for your quote |
|---|---|---|---|---|
| Case rate (DRG) | Payer, by formula | The whole inpatient stay | Medicare inpatient PPS: DRG weight times wage-adjusted base rate, plus adjustments | Ask what defines the case and what triggers extra payment |
| Fee schedule | Payer, by formula | Each service | Medicare anesthesia: (base units + minutes/15) times a local factor | Predictable for that payer only. Other payers set their own rates. |
| Regulated tariff | Government | Each service, in a legal unit | Colombia's tariff manual in UVB for accident, catastrophic-event and unagreed urgent care | A reference value, not an elective self-pay price |
| Market package | Each provider | A defined bundle of services | UK private self-pay packages (PHIN averages by city) | Scope varies by seller. Get inclusions in writing. |
Why the US looks different from all four
The US uses all of these mechanisms at once. Medicare pays hospitals by case rate and pays professionals by fee schedule. Commercial insurers negotiate their own rates from each hospital's list prices, and self-pay patients may be offered yet another figure. Since January 1, 2021, hospitals have had to publish a machine-readable file of all items and services plus a consumer-friendly display of shoppable services. Updated requirements from the 2026 outpatient payment rule have been enforced since April 1, 2026 (CMS, 2026). Those files show the layers side by side. Our chargemaster vs cash price guide explains which layer applies to whom.
The result is that a US "price" is really a family of prices, while a quote abroad is usually a single provider-set number. Comparing them fairly means picking the US figure you would actually pay, not the highest one on display.
How to read a quote by where it came from
A quote that looks like a case rate
Typical wording: "hospital package," "per admission," "includes up to X nights." Ask what is outside the case: professional fees, implants, extra nights, readmission.
A quote built from a fee schedule
Typical wording: separate codes, units or line items. Ask which schedule or rate it uses, and whether the total assumes a set duration.
A quote anchored to a regulated tariff
A provider may mention an official tariff to show that its price is reasonable. Ask whether your elective care is actually billed under that tariff or under the provider's own package. For self-pay foreign patients it is usually the latter.
A market package
Ask for the inclusion list, the validity date, the currency and the change rules. Then compare across providers in the same city before comparing countries.
What this means when you compare countries
- Translate every quote into the same unit, ideally the whole episode, before comparing totals.
- Treat national averages as orientation. Within-country spread can be as large as the gap between countries.
- Do not mistake a regulated reference value, or a Medicare rate, for the price a self-pay patient will be charged.
- For US care, use the price-transparency file or a written estimate to find the figure that applies to you.
A lower cost base is one reason Colombian packages often price below US figures. Our explainer on why Colombia's medical costs run lower covers that side of the story. The pricing mechanism tells you how to read the number, not whether it is good value.
Frequently asked questions
What is a DRG?
A diagnosis-related group is a category used to pay for a whole inpatient stay as one unit. Under Medicare's inpatient system, each DRG has a relative weight that is multiplied by a wage-adjusted base rate, with add-ons for some hospitals and for unusually costly cases (CMS, 2026).
Does Colombia have an official price list for surgery?
Colombia has a regulated tariff manual, expressed in UVB units, that is mandatory for care after traffic accidents and catastrophic events and for other urgent care when the parties have no agreement (MinSalud, 2024). Elective self-pay packages for foreign patients are set by providers.
Why do UK private hospital prices vary so much?
Private hospitals set their own self-pay packages. PHIN's March 2026 averages for a hip replacement range from £13,847 in Glasgow to £17,540 in Cambridge (GBP). Package scope can differ too, so confirm inclusions in writing.
Is the Medicare rate the real price of a US procedure?
It is the price Medicare pays under its own formulas. Commercial insurers negotiate different rates, and self-pay patients may be charged something else. Hospital price-transparency files, required since 2021, show several of these figures side by side.
Which pricing system gives the most predictable quote?
Any system where the unit is clearly defined and written down. A package or case rate with an explicit inclusion list and change rules is easier to budget than a line-item estimate whose total depends on minutes, nights or supplies.
