FAQ

Common questions

Is my data safe?

Yes. All calculations happen directly in your browser — your bill details are never uploaded to a server or stored anywhere outside your own device. We don't require an account or collect personal health information to use the calculator.

Where do the prices come from?

Fair price benchmarks are based on the CMS Physician Fee Schedule, the same publicly available Medicare reference pricing used across the healthcare industry. It's a widely recognized, objective baseline for what a procedure should reasonably cost.

Does disputing a bill actually work?

Many hospitals have a billing department specifically tasked with reviewing disputes, and citing an objective reference price like the CMS fee schedule gives your request real weight. Results vary by provider and situation, and a dispute letter is a starting point for negotiation — not a guarantee — but it's a well-documented first step that costs you nothing to try.
