What patient-provider dispute resolution does
Patient-provider dispute resolution (PPDR) is the federal process CMS runs for people who didn’t have or didn’t use health insurance for their care and then got a bill at least $400 more than the written good faith estimate from that same provider or facility. An independent third party reviews the bill and determines an appropriate payment, according to the CMS page Know your medical bill rights when not using insurance.
You do this after care, once the bill has arrived. If you’re still working out how to pay for detox, including how to ask for an estimate, see our guide to paying for detox.

Compare one provider’s bill with that provider’s estimate
CMS says good faith estimates currently list expected charges for a single provider or facility, even when several are involved in your care.
The bill has to be at least $400 over that provider’s own estimate. A bill that’s exactly $400 over meets the threshold. Keep each comparison separate: check each provider’s bill against the estimate from that same provider.
With both documents in front of you, check these:
- Does the bill name the same provider or facility as the estimate? If more than one provider or facility was involved in your care, match each bill with its own estimate.
- Is this the first bill, or a later statement? Keep the initial bill, because its date starts the clock.
- Do the service dates on the bill match the scheduled care the estimate described?
- Are there charges that don’t match any line on the estimate? CMS notes that you may need care the provider didn’t anticipate, and that care won’t be on the estimate. Mark those lines. The reviewer decides how they’re handled.
Check your facts against the CMS eligibility list
The CMS Dispute a medical bill page (last modified 10/02/2026) says you can only dispute a bill if all of these are true:
- When you got care, you didn’t have health insurance, or you had it but didn’t use it to pay.
- Before care, you told the provider you weren’t using insurance to pay for it.
- You got care on or after January 1, 2022.
- You have a good faith estimate that you received from the provider or facility three (3) days before your scheduled appointment.
- You have an initial bill dated within the last 120 calendar days (about 4 months).
- One of your providers or facilities charged at least $400 more than its good faith estimate.
That three-day wording comes from the CMS eligibility list for this dispute. If your estimate came later than that, or you can’t tell when it came, use the Check if you’re eligible link on CMS’s Without insurance page, or call the No Surprises Help Desk at 1-800-985-3059. Do that before you decide whether you qualify.
The 120 days are calendar days, so weekends count. Count from the date on your initial bill (the CMS form asks about “the date on the top of the bill”). If the bill reached you much later than that date, ask the No Surprises Help Desk at 1-800-985-3059 how to count your days. Either way, file as early as you can. CMS says “It’s important not to delay.”
A worksheet for the bill and the estimate
In the Why column, “Form” marks something the CMS dispute form asks for, and “Eligibility” marks a condition from CMS’s eligibility list. Rows marked “Suggested” are our own ideas for keeping track. Leave the last column blank until you have your documents.
| Record | Why | Your entry |
|---|---|---|
| Provider or facility name on the estimate | Form. The form says the provider’s contact information should be on your estimate. | |
| Provider or facility name on the bill | Suggested: helps you check that the bill and estimate come from the same provider | |
| Date the written estimate reached you, and the scheduled appointment date | Eligibility: CMS’s list refers to an estimate received three (3) days before your scheduled appointment | |
| Date or dates you got the care, and the state where you got it | Form | |
| Short description of the service | Form | |
| Date on the initial bill | Eligibility: starts the 120-calendar-day count | |
| Day 120 counted from that date | Suggested. A note of your own deadline | |
| Insurance status for this care (none, or had it but didn’t use it) | Eligibility: part of the CMS eligibility list | |
| When and how you told the provider you weren’t using insurance | Suggested. Relates to one of the eligibility conditions | |
| Total on this provider’s estimate | Suggested: for the $400 comparison | |
| Total on this provider’s bill | Suggested: for the $400 comparison | |
| Bill total minus estimate total | Eligibility: needs to be at least $400 | |
| Provider contact: name, facility or group, street, city, state, ZIP, email, phone | Form. It says this should be on your estimate | |
| Digital or paper copies of the estimate and the bill | Form. Keep your originals and send copies | |
| Calls with the billing office: date, who you spoke with, what was said | Suggested |
Filing the dispute and paying the $25 fee
You can start a dispute on CMS’s online form at https://nsa-idr.cms.gov/billdisputes/s/. You can also send the paper Patient-Provider Dispute Resolution Form (PDF) by mail or fax. CMS says not to mail any original documents.
The PDF starts with three yes-or-no questions: whether you got an estimate, whether the bill is at least $400 over it, and whether the bill’s date is within the last 120 calendar days. Along with completing the form, review the eligibility conditions on CMS’s Dispute a medical bill page. When you sign, you agree that the provider can release relevant records to the dispute resolution entity HHS selects, that you’ll pay the fee, and that you’ll pay whatever amount that entity decides. Mail paper forms to StrategyGen Co., Patient-Provider Dispute Resolution, 50 N. Laura Street, Ste 2500, Jacksonville, Florida 32202, or fax them to 904-245-1826. The form also says to keep a copy or take pictures of it after you fill it in.
The $25 administrative fee is non-refundable, and the dispute doesn’t start until it’s paid. According to the form, HHS sends you a link to pay electronically after it receives your form, and you can pay by card or payment app. If you mail the form, you can include a cashier’s check or money order. Cash and personal checks aren’t accepted. If the dispute is decided in your favor, CMS says the $25 comes off the amount you owe the provider.
Next, the provider is asked for the estimate, the bill and any documents that explain why the bill is higher, according to CMS’s Providers: payment resolution with patients page. The dispute resolution entity tells you and the provider what it decided. CMS says the reviewer may find the cost of your care was appropriate and leave your bill as is, or may find that your provider must reduce your bill. It also says your costs won’t increase because you disputed.
While the dispute is open
CMS’s provider page says that during the patient-provider dispute resolution process, providers:
- can’t move the bill into collections or threaten to
- must pause collections if the bill is already in collections
- can’t collect late fees on unpaid amounts
- can’t threaten to take any action against you because you started the dispute
You can keep negotiating during the dispute. The form notes that you can still ask the provider for a lower bill. If you settle before a decision is made, CMS’s patient page says the provider must cut the bill by at least $12.50 (half the fee) and notify the reviewer. The provider page says that notice has to go out as soon as possible, but no later than 3 days after the settlement.
If you don’t meet a condition
- No written estimate: CMS says you can’t use this dispute process without one. It points you to Find an action plan, and to Submit a complaint for a provider that didn’t give you an estimate. You’ll find both on the Dispute a medical bill page.
- Less than $400 over the estimate, or an initial bill dated more than 120 calendar days ago: if you answer no to any of the form’s screening questions, the form tells you to contact the provider to negotiate and ask about financial assistance. For other questions, it points to https://www.cms.gov/nosurprises/consumers or the help desk at 1-800-985-3059.
- Insurance used for this care: CMS says you don’t qualify for this dispute. It lists complaints for certain No Surprises Act problems with care on or after January 1, 2022. If you think an insurer’s payment decision violates the No Surprises Act, it points to the appeal process described in your plan’s documents and denial notices. For coverage questions, see our guide Does Insurance Cover Substance Abuse Detox?
- Not sure where you stand: call the help desk number above, which TTY users can call as well, or email FederalPPDRQuestions@cms.hhs.gov. You can also visit the Detox Local Resources page.
Frequently asked questions
Can a family member file the dispute for me?
Yes. The CMS form has a box an authorized representative can check if they should be contacted instead of the patient. The form says this is common for patients under 18 or for people who need help with medical forms.
Could disputing raise what I owe?
No. The CMS Dispute a medical bill page says your costs won’t increase whatever the outcome. But the reviewer can leave the bill as it is if it finds you needed care the provider couldn’t reasonably have anticipated.
What if the provider keeps billing me after a decision in my favor?
CMS says to submit a complaint to the No Surprises Help Desk. It’ll review the situation and tell you what to do next.
Can I get help with the form in another language or format?
Yes. The form says the Help Desk at 1-800-985-3059 can help with filling it out and with language services. You can also ask for large print, Braille or audio at no cost.
