This is not the process for every insured bill or emergency visit. CMS eligibility rules and the facts of your care determine the available route.
Ask before scheduled care
CMS says self-pay patients generally can request a good faith estimate; scheduling at least three business days ahead also triggers estimate rules. Ask separately about each provider or facility because one estimate may not include everyone.
CMS lists a $400-or-more difference for one provider or facility, an initial bill within 120 calendar days, and other eligibility conditions. Its dispute page currently also specifies an estimate received three days before the appointment.
Save the estimate and itemized bill. CMS lists a $25 administrative fee; a favorable decision deducts it from the amount owed. Review is not a guaranteed reduction, since unanticipated necessary care may justify charges.
