Quick Answer: As of 2026, the top medical bill negotiation services include Goodbill (20% fee, $1,000 cap), Resolve Medical Bills (10-25% tiered, 70% success rate), and Dollar For (free, charity care only). The CoveredUSA Bill Analyzer is a free, instant alternative that compares every charge on your bill to the 2026 Medicare rate and surfaces charity care eligibility before you pay anyone a percentage.
About 80% of U.S. hospital bills contain at least one error, according to research compiled by the Medical Billing Advocates of America. The average overcharge on a bill exceeding $10,000 runs roughly $1,300. Before you pay a negotiation service 20-40% of your savings, it helps to know exactly what you are dealing with. The CoveredUSA Bill Analyzer scans your itemized hospital bill, compares each CPT-coded charge to the 2026 Medicare reimbursement rate, and flags specific line items to dispute, all at no cost. Once you know what errors exist, you can decide whether to handle the dispute yourself or hire a service.
This guide compares 10 medical bill negotiation services side by side, including fees, what each service does and does not cover, and when each one makes sense for your situation.
What Medical Bill Negotiation Services Actually Do
Medical bill negotiation services review your hospital or medical bills for errors, duplicate charges, and upcoding. They then negotiate directly with the provider on your behalf to reduce the balance. Some also screen for hospital charity care programs, also called financial assistance, that can eliminate bills entirely for patients below certain income thresholds.
There are three general categories:
- Full-service negotiators. They audit your bill, negotiate, appeal denials, and handle paperwork. You pay a percentage of savings if they succeed.
- Charity care specialists. They identify and apply for hospital financial assistance programs on your behalf. Most are free or nonprofit.
- DIY-assist tools. They analyze your bill and give you a dispute roadmap, but you do the actual negotiating.
Understanding which category fits your situation saves you money on the service itself.

CoveredUSA Bill Analyzer
Best for: Anyone who wants to understand their bill before paying a negotiation fee.
The CoveredUSA Bill Analyzer is a free tool at coveredusa.org/medical-bill-analyzer that compares each line on your itemized bill to the Medicare reimbursement rate for that procedure code. It identifies upcoding, duplicate charges, and unbundling errors, then tells you which specific charges to dispute and why. It also checks your income against hospital charity care thresholds to see if you qualify for a full or partial write-off.
Unlike the services below, the CoveredUSA Bill Analyzer does not negotiate for you. It gives you the data to negotiate yourself or to know exactly what to hand off to a professional advocate. Most people find that once they have a line-by-line comparison showing their hospital charged $4,200 for a procedure Medicare reimburses at $900, the conversation with the billing department becomes much shorter.
Fee: Free
Works with collections: N/A (analysis tool)
Charity care screen: Yes
Goodbill
Best for: Hospital bills where you suspect overcharges and want someone to handle the paperwork.
Goodbill reviews your hospital bill for errors and negotiates directly with the hospital on your behalf. It also screens your eligibility for 501(r) charity care programs, which can result in a larger reduction than negotiation alone. Goodbill does not work with bills that have gone to collections, and it focuses exclusively on hospital bills rather than physician, lab, or imaging bills.
Fee: 20% of savings, capped at $1,000
Minimum bill size: None published
Works with collections: No
Charity care screen: Yes
Success rate: Not publicly published
The $1,000 cap makes Goodbill particularly attractive on very large bills. If Goodbill negotiates a $30,000 bill down by $15,000, you pay $1,000 instead of $3,000 (20% uncapped). On smaller bills the cap is irrelevant.
Resolve Medical Bills
Best for: Bills that have gone to collections, or large bills where you want a dedicated human advocate.
Resolve assigns a dedicated advocate who handles negotiation, appeals, and financial assistance applications. Resolve's tiered fee structure means larger savings carry a lower percentage rate. The service requires a $249-$499 upfront deposit that is applied to the final success fee or refunded if Resolve cannot lower your bill.
Resolve's published average savings rate is 60%, with a 70% success rate across cases, meaning roughly 3 in 10 cases result in no reduction. The service accepts bills that have gone to collections, which Goodbill does not, making it an option when the debt is already in a collection agency's hands.
Fee: 10-25% tiered (no cap)
Minimum bill size: $5,000
Upfront deposit: $249 (bills $5K-$15K), $499 (bills over $15K)
Works with collections: Yes
Charity care screen: Yes
Success rate: 70%, average 60% savings when successful
The lack of a fee cap means a very large successful negotiation costs more in absolute dollars than Goodbill. On a $50,000 bill reduced by $30,000, you could owe $3,000-$7,500 depending on the tier versus $1,000 with Goodbill.
Dollar For
Best for: Patients whose income qualifies for hospital charity care but who do not know how to apply.
Dollar For is a national nonprofit that focuses exclusively on hospital charity care applications. It does not negotiate bills or dispute charges. It identifies whether your hospital has a financial assistance program and handles the paperwork to apply. In 2025, Dollar For helped patients eliminate $55 million in hospital bills, per KFF Health News reporting.
Under Section 501(r) of the Internal Revenue Code, all nonprofit hospitals (roughly 60% of U.S. hospitals) are required to offer charity care to qualifying patients. Most set full write-offs at incomes up to 200% of the Federal Poverty Level (FPL) and partial discounts up to 400% FPL. For 2026, 200% FPL is $31,920 for a single person and $66,000 for a family of four.
| Household Size | 200% FPL (2026) | 400% FPL (2026) |
|---|
| 1 | $31,920 | $63,840 |
| 2 | $43,280 | $86,560 |
| 3 | $54,640 | $109,280 |
| 4 | $66,000 | $132,000 |
| 5 | $77,360 | $154,720 |
| 6 | $88,720 | $177,440 |
| 7 | $100,080 | $200,160 |
| 8 | $111,440 | $222,880 |
| Each additional | +$11,360 | +$22,720 |

Service type: Nonprofit
CoPatient
Best for: Patients who want a lower-cost audit before paying a full negotiation service.
CoPatient reviews medical bills and negotiates with providers when it identifies savings opportunities. The average savings reported is about 20%, and the fee is 35% of savings. CoPatient handles various bill types beyond hospital bills, including physician and specialist invoices.
Fee: 35% of savings
Average savings: ~20%
Works with collections: Not published

BillShark
Best for: Recurring bills and non-medical service bills, though the service handles medical bills as well.
BillShark gained prominence through a Shark Tank appearance and reports an 85-90% success rate. The 40% commission is the highest of any major service on this list, making it more expensive relative to savings than Goodbill or Resolve on large medical bills. BillShark works well for patients who want a single service to handle medical and non-medical bills (utilities, subscriptions, cable) simultaneously.
Fee: 40% of savings
Success rate: 85-90%
Minimum bill size: None published
Works with collections: Not published
Charity care screen: No
CareRoute
Best for: Patients who want a multi-strategy approach covering hospital, physician, imaging, and lab bills under one roof.
CareRoute applies every available reduction strategy to each case: billing error correction, financial assistance applications, insurer dispute resolution, and direct provider settlement. The fee is 25% of savings capped at $1,000. CareRoute reports average savings of 30% and up to 80% in resolved cases.
Fee: 25% of savings, capped at $1,000
Average savings: 30%
Minimum bill size: None

PatientAdvocate Foundation
Best for: Patients dealing with chronic illness, insurance appeals, or systemic coverage problems alongside billing issues.
The PatientAdvocate Foundation is a nonprofit that provides case management services for patients with serious illness. Its services extend beyond bill negotiation into insurance appeals, access to treatment, and co-pay relief funds. The foundation does not charge patients for its services.
Fee: Free (nonprofit)
Works with collections: No
Charity care screen: Partial
Scope: Broader than bill negotiation
How to Choose the Right Service
The right service depends on three factors: your income level, the size of your bill, and whether the bill is already in collections.
If your income is below 200-400% FPL: Start with Dollar For or the CoveredUSA Bill Analyzer to check charity care eligibility first. A full forgiveness through charity care costs you nothing and beats any negotiated reduction.
If your bill is under $5,000 and you want professional help: Goodbill or CareRoute offer no-minimum options with fee caps.
If your bill is over $5,000 and in collections: Resolve is the primary option that works with collections accounts and bills in that size range.
If you want to negotiate yourself: Use the CoveredUSA Bill Analyzer to get a line-by-line comparison against Medicare rates, then call the hospital billing department directly with that data.
If you want maximum savings with the lowest fee cap: Goodbill's $1,000 cap makes it the strongest option for bills where negotiations are expected to exceed $5,000 in savings.
How to Apply for Hospital Charity Care (Step-by-Step)
Most patients are unaware that nonprofit hospitals are legally required to offer financial assistance. Here is the process to apply directly, without hiring a service.
Enrollment window: You can apply for charity care at most hospitals before, during, or after receiving care. Many hospitals retroactively apply charity care to bills already issued. Submit as early as possible, since some hospitals require applications within 240 days of the billing statement date per IRS Section 501(r) rules.
Application steps:
- Request the hospital's Financial Assistance Policy (FAP) and application form from the billing department. Under IRS Section 501(r), nonprofit hospitals are required to provide this on request.
- Look up the hospital's specific income thresholds. Many exceed the 200% FPL minimum required by law.
- Gather your documents (list below).
- Submit the completed application with supporting documents to the billing department or financial assistance office.
- Follow up in writing within 2 weeks if you have not received a decision.
- If denied, appeal in writing citing the hospital's published FAP and your documented income.
- If the hospital does not respond or denies without cause, file a complaint with the Consumer Financial Protection Bureau or your state attorney general.
Documents needed:
- Most recent federal tax return (Form 1040)
- Two to three recent pay stubs or proof of income
- Bank statements (last 1-3 months)
- Proof of public benefits received (Medicaid, SNAP, SSI)
- Photo ID
- Hospital account number or billing statement
Common reasons charity care applications get denied:
- Incomplete documentation (missing income proof or tax return)
- Application submitted after the hospital's deadline
- Hospital is for-profit and not subject to 501(r) requirements
- Household income slightly above the threshold (ask about partial discount tiers)
- Wrong application form submitted (some hospitals have separate forms for uninsured vs. insured patients)
Frequently Asked Questions
What is a medical bill negotiation service?
A medical bill negotiation service reviews your medical bills for errors, overcharges, and duplicate charges, then negotiates with the provider or insurer on your behalf. Most charge a percentage of whatever savings they achieve. Some also apply for hospital charity care programs, which can reduce or eliminate bills entirely for qualifying patients.
How much can I expect to save with a medical bill negotiation service?
Savings vary by service and case. Resolve reports an average 60% reduction when successful. CareRoute reports 30% on average. BillShark clients reportedly save an average of $300 per year across all bill types. A 2026 study cited by aptarro.com found that the average hospital bill over $10,000 contains roughly $1,300 in overcharges, though some bills contain far more.
Are medical bill negotiation services worth the fee?
They can be, particularly on large bills. If Goodbill negotiates $10,000 off a $25,000 hospital bill, you pay $1,000 (the cap) and net $9,000 in savings. However, if your income qualifies for charity care, you may be able to eliminate the entire bill through Dollar For or the hospital's own financial assistance program at no cost. Always check charity care eligibility before hiring a fee-based service.
What is the difference between medical bill negotiation and charity care?
Negotiation reduces what you owe through error correction or direct bargaining with the provider. Charity care (financial assistance) is a separate program that nonprofit hospitals are legally required to offer patients below certain income thresholds, often resulting in a complete bill write-off. Charity care is income-based; negotiation is not. Some services, including Goodbill and Resolve, screen for both.
Can I negotiate my own medical bill without a service?
Yes. Call the hospital billing department, ask for an itemized bill, and request a comparison to the hospital's chargemaster rates and Medicare rates for each procedure. The CoveredUSA Bill Analyzer automates this comparison for you. Upload your bill and it identifies specific overcharges with the supporting Medicare rate data, giving you the exact information you need to make the call.
What is the free CoveredUSA Bill Analyzer and how does it work?
The CoveredUSA Bill Analyzer is a free tool at coveredusa.org/medical-bill-analyzer that accepts your itemized hospital bill and compares each CPT-coded charge to the 2026 Medicare reimbursement rate. It flags upcoding, duplicate charges, and unbundling errors by line item, and checks whether your income qualifies for charity care at that hospital. The analysis takes approximately 30 seconds.
Does medical bill negotiation hurt my credit?
Using a negotiation service does not itself affect credit. However, if a bill is already in collections, the collection account may already be on your credit report. Settling a collections account through negotiation typically results in the account being marked "settled" rather than "paid in full," which can still affect your score. Review the specific credit implications with the service before proceeding on collections accounts.
What income qualifies for hospital charity care in 2026?
Most nonprofit hospitals provide full write-offs for patients with household income at or below 200% of the Federal Poverty Level. For 2026, that is $31,920 for a single person and $66,000 for a family of four, per aspe.hhs.gov. Partial discounts typically extend to 400% FPL. Some hospitals are more generous. Eligibility thresholds range from 41% to 600% FPL depending on the institution, according to a Health Affairs study.
Do I need to hire someone to get charity care?
No. Dollar For helps patients apply for free. You can also apply directly to the hospital's billing department without any third-party service. Having your income documentation ready and submitting before the deadline (often 240 days from first billing statement) are the two most important factors.
Upload your hospital bill to the free CoveredUSA Bill Analyzer to find errors, overcharges, and charity care options in 30 seconds.
