Methodology

Where these numbers come from.

Every figure on this site is one of two things: sourced from a named dataset or piece of reporting, or modeled by us from stated inputs. This page says which is which.

If a number here cannot be traced to a source or a method, it is a bug. Point it out and it gets corrected or removed.

Sourced figures

Published by someone else. We report the number and link to it.

Modeled figures

Computed by us from stated inputs. Useful for comparison between options. Not a quote, not a bill, and not clinical advice.

Procedure and supply pricing

Cash, commercial, Medicare, and chargemaster figures on the pricing pages are computed from published input costs, wage indices, and state price ratios. They are reference estimates for comparison, not quotes from a specific hospital.

Care denial volumes

The denial pathway tables are a composite built from documented industry patterns. They illustrate mechanism and scale. They are not any single insurer's denial log.

Country treatment comparisons

Per-country treatment and prevention descriptions are composed from health-system archetypes and disease pathways. They describe how a system typically approaches a condition. They are not clinical guidelines and must not be used for treatment decisions.

International lobbying figures

US figures are anchored to OpenSecrets. Other countries are estimated from thinner disclosure regimes. These describe legal lobbying spend, not proven corruption.

How we handle people’s stories

Only what they published

Cases come from fundraisers people posted themselves or interviews they gave to reporters. We do not search private records, and we do not add medical detail beyond what the person chose to share.

Always attributed

Each case links to the original reporting and, where the fundraiser is still open, to the fundraiser itself. Donations go to the family directly. We do not collect them.

Corrections

If you are featured here and want your case removed or corrected, it will be done on request.

What this site is not

  • Not medical advice. Nothing here should be used to choose or refuse treatment.
  • Not legal or financial advice, and not an insurance product.
  • Not a bill or a quote. Prices are reference estimates. Ask any provider for their own price in writing.

The pricing methodology for individual procedures is documented on the evidence pages, where each input is listed with its source.
