In short
- If you did not use insurance, you may be able to dispute a bill that is $400 or more over the estimate.
- You need the good faith estimate and an initial bill dated in the last 120 days.
- A $25 fee applies, and your costs will not go up.
What this means
CMS says you can dispute a bill only if all of these are true [1]. You didn't have or didn't use health insurance for the care. You told your provider before the care that you weren't using insurance. You got the care on or after January 1, 2022. You have a good faith estimate you got three days before your appointment. You have an initial bill dated in the last 120 days. And one provider or facility charged at least $400 more than its estimate [1].
There is a $25 fee that is not refunded. The dispute does not start until you pay it. If the decision is in your favor, the $25 is taken off what you owe your provider [1]. CMS says your costs won't go up, whatever the outcome [1].
Your next step
Gather your good faith estimate and the first bill, and check the bill date (it must be in the last 120 days). Then start the dispute on the CMS page; the fee is $25.
