Ask before the service
Tell the office that you will not use insurance and ask for a good faith estimate for the specific planned visit or procedure. CMS says a provider generally must give one when qualifying care is scheduled in advance or when you request it. Ask which related services and providers the estimate includes.
Keep the written estimate and any later revision. A good faith estimate is an expected charge, not a promise that the plan cannot change. If the proposed service changes, request an updated estimate before deciding.
Compare the bill with the estimate
When the bill arrives, compare each provider's charges with that provider's estimate. CMS explains that an eligible uninsured or self-pay patient may use a federal dispute process when a bill is at least $400 above the good faith estimate and other conditions are met. The CMS page gives the current eligibility and deadline details; use it rather than relying on a short summary.
Whether a particular bill qualifies depends on CMS rules and the documents in the case. Save the original estimate and bill, then check the current federal guidance if a discrepancy arises.
Make the request specific
Name the planned service, expected date, and whether related imaging, medication, facility or device work is anticipated. Ask who will issue the estimate for each part. CMS describes the good faith estimate process for uninsured and self-pay patients; that federal guidance is the place to check the current rules, exceptions and dispute process before relying on a short summary.
