If your medical bill is in the thousands, you don't have to fight it alone, a growing number of services will investigate the charges and negotiate on your behalf. But they don't all work the same way, and the fee structures vary enough to matter. Here's an honest, head-to-head comparison of the leading medical bill negotiation services in 2026, including our own.
Quick answer
The best medical bill negotiation service depends on how you want to pay. mediloop charges a flat fee with a money-back guarantee, best when you want predictable, capped cost. Goodbill, Resolve, and CareRoute charge a percentage of savings under their published terms. Dollar For provides free hospital charity-care application help rather than general negotiation.
A quick note on honesty: mediloop is one of the services in this comparison, so we have a stake in it. We've tried to describe every option fairly and accurately, including where a competitor or a free option is the better fit for your situation. Fees listed are as advertised at the time of writing and can change, so always confirm the current terms directly with each service before you sign up.
Methodology: how we selected and compared providers
We reviewed U.S. services that were accepting individual medical-bill cases online on July 27, 2026 and published enough information to compare their scope or pricing. We selected established direct-to-consumer advocates that represent the main options a patient is likely to encounter: flat-fee negotiation, contingency-fee negotiation, broad advocacy, and free charity-care assistance. We excluded general debt settlement companies, legal practices without a standard consumer service, insurance-only navigation tools, and providers whose current service terms could not be confirmed. mediloop is included because it is one of those options; the conflict-of-interest disclosure above applies to our selection and conclusions.
We compared each provider on the same four dimensions:
- Total consumer cost, including the advertised fee, percentage, cap, deposit, and any stated minimum
- Eligibility and bill scope, including minimum bill size, payment or collections status, and supported bill types
- Work performed, including provider negotiation, billing review, insurance appeals, and charity-care help
- Downside risk, including upfront charges and what the consumer owes when no savings are found
Competitor facts come from the provider's own pricing, FAQ, or service pages, not affiliate roundups. Each linked claim and table row shows the date we last checked it. “Best for” labels are editorial judgments based on those published terms, not a claim that we tested every service or independently verified its advertised outcomes. Prices and eligibility rules can change, so confirm the linked terms before enrolling.

The services, reviewed
mediloop, best for predictable, capped cost
mediloop charges a flat fee, $69 for an EOB review, $129 to negotiate a single bill, or $499/year for six bills, and never takes a percentage of your savings. On a large reduction, that's a meaningful difference: save $8,000 and a 25% service keeps $2,000, while mediloop's fee stays $129. The per-bill plan carries a 100% money-back guarantee, so if your bill isn't reduced, you pay nothing. Agent Loop handles hospital, ER, surgery, ambulance, and out-of-network bills. Best for people who want to know their exact cost upfront.
Goodbill, best for hospital bills and charity-care screening
Goodbill supports unpaid hospital bills that have not gone to collections, reviews them for coding errors, and screens for financial-assistance opportunities. Its official pricing page says it charges 20% of savings, capped at $1,000, with no fee when no settlement is accepted. Verified July 27, 2026. Strong choice for a large hospital bill if you're comfortable with a percentage model. For a detailed head-to-head, see our mediloop vs Goodbill comparison, or, if you're shopping beyond Goodbill, the Goodbill alternatives roundup.
Resolve, best for complex bills, including collections
Resolve assigns a dedicated advocate and works with providers and insurers, including on complex cases and bills in collections. Its published terms apply to bills of at least $5,000:a $249 deposit and 25% success fee for $5,000-$15,000 bills, or a $499 deposit and 10% success fee above $15,000. The deposit is credited to the success fee or refunded if no savings are found; minimum-fee rules can apply, and the page does not state an overall dollar cap. Verified July 27, 2026. Good for messy, high-dollar situations. For a detailed head-to-head, see our mediloop vs Resolve comparison.
CareRoute, best for working both sides of the bill
CareRoute says it works provider and insurer disputes and accepts hospital, ER, physician, imaging, lab, surgical-center, and collections bills. Its official pricing is 25% of savings, or 18% for premium app subscribers, capped at $1,000, with $0 upfront and no fee if the bill is not reduced. Verified July 27, 2026.For a detailed head-to-head, see our mediloop vs CareRoute comparison.
Medical Cost Advocate, best for a long track record
Medical Cost Advocate says it has operated since 2002 and serves individuals, families, employers, and payer organizations. For web-direct bill negotiation, its official process page lists no upfront fee, a 35% share of savings, and no negotiation fee when it finds no savings; that page does not state a dollar cap. Verified July 27, 2026. A solid, established option if longevity matters to you.
Dollar For, best free option (charity care only)
Dollar For is a nonprofit that helps patients check eligibility and apply for hospital charity care at no cost. It is not a general bill-negotiation service: eligibility and the available discount depend on the hospital's own financial-assistance policy, household size, income, and other policy requirements. Verified July 27, 2026.If charity care may apply, start there before paying for negotiation; we've mapped exactly where that line sits in mediloop vs Dollar For.
The next step is a phone call, a hold queue, and a supervisor who has heard it before. That part we do for you, and only charge if the bill comes down.
Let us make the callFlat fee vs. percentage of savings
This is the single biggest decision, so it's worth understanding the trade-off clearly.
- Percentage of savings means you pay nothing if nothing is saved, but your cost rises with your reduction. A 25% fee on a $10,000 savings is $2,500. A cap (like $1,000) limits the downside, but not every service has one, and some require a deposit.
- Flat fee means you know your cost before anyone starts. You keep all savings above the fee, which is most valuable on large reductions. The trade-off is that on a small saving the flat fee could be a higher share, which is why a money-back guarantee matters: if the bill isn't reduced, you shouldn't pay.
Rule of thumb: the larger your expected reduction, the more a flat fee works in your favor. For a deeper look at fees and when professional help pays off, see Is a medical bill advocate worth it?
How to choose the right one
- Tiny or simple bill (under ~$500)? Try it yourself first with our hospital bill negotiation guide.
- Hospital bill and possible financial-assistance eligibility? Check the hospital's policy or use Dollar For's free eligibility and application help.
- Large bill and you want a known cost? A flat-fee service like mediloop.
- Comfortable with a percentage-based fee? Compare the linked terms for Goodbill, Resolve, and CareRoute, including deposits, minimums, and caps.
- Bill already in collections or highly complex? Resolve accepts high-dollar cases and describes collections support; CareRoute also says it accepts collections bills.
Whatever you choose, confirm three things before signing: the exact fee, whether there's a cap or deposit, and what happens if they can't reduce the bill.
Frequently asked questions
What is the best medical bill negotiation service?
There's no single winner for everyone. Choose a flat-fee service when you want a predictable, capped cost; choose a percentage service when you'd rather pay nothing unless they win; and start with a free charity-care nonprofit if you may qualify based on income.
Is there a service that negotiates medical bills for you?
Yes. Several companies negotiate medical bills on your behalf, and they fall into three camps. mediloop negotiates hospital, ER, surgery, ambulance, and out-of-network bills for a flat fee with a money-back guarantee. Goodbill, Resolve, and CareRoute do the same work for a percentage of what they save you, under the terms linked in the table above. And Dollar For is a free nonprofit that handles hospital charity-care applications rather than negotiation. Whichever camp fits, confirm the fee, the eligibility rules, and what you owe if no savings are found before you hand over the bill.
Are these services worth it?
For bills over about $1,000, especially hospital, surgery, ER, and out-of-network bills, they usually pay for themselves, because roughly 80% of bills contain errors and trained negotiators know where to look.
Will using a service hurt my credit?
No. Negotiating or disputing a bill doesn't affect your credit. (Medical debt reporting rules also changed in 2025, see does medical debt affect your credit score.)
