“Patients are increasingly turning to artificial
intelligence to combat excessive medical charges. One patient, faced with a
$14,017 bill for her newborn's hospital stay, used AI to analyze her charges
and discovered many were above state and national averages. This led to
negotiations that significantly reduced her costs.” — New York Post,
March 8, 2025
Imagine receiving a medical bill that seems inflated or
includes charges for services you didn't receive. You're not alone. In 2025,
many patients face similar challenges with medical billing errors.
Understanding how to dispute these charges effectively can save you time,
money, and stress.
Understanding Medical Billing Errors
Medical billing errors can range from simple mistakes to
complex issues involving insurance miscommunications. Common errors include:
- Duplicate
Charges: Being billed more than once for the same service.
- Incorrect
Coding: Procedures or diagnoses being billed under the wrong codes.
- Out-of-Network
Charges: Receiving bills for out-of-network services when you believed
the provider was in-network.
- Balance
Billing: Being charged the difference between what your insurance paid
and what the provider billed, especially in emergency situations.
Statistics & Data Insights on Medical Billing
Disputes
Understanding the scope and scale of medical billing
issues is crucial for patients, providers, and policymakers. Here are key
statistics and insights:
- Prevalence
of Billing Errors
- Studies
show that up to 80% of medical bills contain errors, ranging from
minor clerical mistakes to significant overcharges.
- Common
errors include duplicate charges, incorrect coding, and out-of-network
billing. (CMS, 2025)
- Patient
Financial Impact
- Americans
spent over $100 billion in 2024 on unexpected medical bills, with
a significant portion arising from billing errors or surprise
out-of-network charges.
- On
average, patients spend $400–$600 per error correction due to
dispute resolution processes. (AMA, 2025)
- Dispute
Success Rates
- Roughly
60–70% of formal billing disputes result in partial or full
corrections when patients provide detailed documentation.
- Patients
who escalate disputes to insurance companies or state regulators see higher
success rates (~80%). (Patient Rights Advocate, 2025)
- Insurance
Coverage Confusion
- A
2025 survey revealed that 55% of patients did not fully understand
their Explanation of Benefits (EOB), which contributes to delays in
identifying billing errors.
- Impact
of the No Surprises Act
- Since
implementation, the No Surprises Act has reduced out-of-network
surprise billing by approximately 25%, but gaps in enforcement still
leave millions of dollars in disputed charges unresolved.
- Complaint
Trends
- Consumer
complaints to regulators show a 40% increase in billing disputes from
2023 to 2025, reflecting greater patient awareness but persistent
systemic issues.
Tracking these statistics can help providers identify
common billing issues, and empower patients to understand their rights
and prioritize disputes that could save them significant amounts.
Expert Opinions on Medical Billing Disputes
To provide a well-rounded perspective, we've gathered
insights from three experts in the field:
- Dr.
Sarah Thompson, Health Policy Expert
"Patients should always request an itemized bill. It's a fundamental step in identifying errors and ensuring transparency in healthcare costs." - John
Davis, Medical Billing Specialist
"Understanding your Explanation of Benefits is crucial. It helps patients differentiate between what they owe and what their insurance has already paid." - Emily
Roberts, Consumer Rights Advocate
"Don't hesitate to escalate the issue. If you're not getting the answers you need, filing a formal appeal or seeking external assistance can make a significant difference."
Common Myths About Medical Billing Disputes
- Myth:
"If I don't pay the bill, my credit will automatically be
affected."
Fact: While unpaid bills can impact your credit, disputing a bill doesn't mean you won't have to pay. It means you're questioning the charges and seeking clarification. - Myth:
"Medical billing errors are rare."
Fact: Studies show that a significant percentage of medical bills contain errors, ranging from minor mistakes to substantial overcharges. - Myth:
"Once a bill is sent to collections, it's too late to
dispute."
Fact: You still have rights to dispute a bill even if it's in collections. It's important to act promptly and seek assistance.
Recent News: Navigating the Evolving Landscape of Medical
Billing Disputes
Recent developments in healthcare policy and enforcement
underscore the complexities patients and providers face in medical billing
disputes. While the No Surprises Act aimed to protect patients from unexpected
out-of-network charges, its implementation has revealed significant challenges.
1. Enforcement Gaps in the No Surprises Act
Despite the No Surprises Act's intent to shield patients
from surprise medical bills, many health plans have failed to comply with
statutory timelines for payment after an independent dispute resolution (IDR)
entity has made a final and binding determination. This non-compliance has
prompted the introduction of the No Surprises Act Enforcement Act (H.R. 4710;
S. 2420), bipartisan legislation aimed at imposing penalties on parties that do
not adhere to statutory timelines for payment after an IDR entity has made a
final and binding determination. The bill seeks to reinforce the original
intent of the No Surprises Act by closing enforcement gaps through increased
penalties. U.S. Senator Michael Bennet+1
2. Surge in Billing Complaints
In 2025, approximately 90% of the 2,058 complaints received
by the West Bengal Clinical Establishment Regulatory Commission (WBCERC)
against private hospitals and nursing homes were related to billing issues. In
response, the West Bengal government introduced The West Bengal Clinical
Establishments (Registration, Regulation and Transparency) (Amendment) Bill
2025 to enforce billing transparency. The bill mandates hospitals to display
treatment rates, including OPD, doctor fees, and package costs, both physically
and on websites. It also requires the disclosure of additional charges within
24 hours to patients. The Times of India
3. Legal Actions Against Improper Billing
The U.S. Justice Department has initiated a civil fraud
investigation into UnitedHealth's Medicare billing practices, creating concerns
over how the company records diagnoses to secure additional payments for its
Medicare Advantage plans. The probe has caused UnitedHealth's shares to drop
nearly 10% in premarket trading. Reuters
4. State-Level Legislative Actions
In New York, a coalition is supporting legislation known as
the "Fair Pricing Act," aimed at capping medical bills at
hospital-owned outpatient clinics to a maximum of 150% of Medicare rates. The
act is a response to the substantial price disparities patients face for the
same medical procedures, depending on whether they go to a private practice or
a hospital-run clinic. The legislation garners backing from unions such as
Local 32 BJ, the Real Estate Board of New York, and various advocacy groups
like the NAACP. Key proponents argue that the act would make healthcare more
affordable by preventing price hikes driven by hospital ownership. Conversely,
the Greater New York Hospital Association opposes the bill, citing financial
challenges and regulatory burdens exclusive to hospitals, and suggests the
legislation could drive patients to seek care outside the state. New York Post
These developments highlight the ongoing challenges and
efforts to address medical billing disputes. Patients, providers, and
policymakers must remain vigilant and proactive in navigating this complex
landscape.

Common Pitfalls to Avoid When Disputing Medical Bills
Disputing a medical bill can be challenging, and certain
missteps can delay resolution or reduce your chances of success.
Awareness of these pitfalls will help you navigate the process more
efficiently:
- Ignoring
the Bill
- Waiting
too long to address a questionable charge can lead to collections,
credit impact, or missed deadlines for disputes.
- Tip:
Act promptly and keep detailed records from the first notice.
- Failing
to Request an Itemized Bill
- Without
an itemized breakdown, it’s nearly impossible to identify duplicate
charges, coding errors, or incorrect service dates.
- Not
Comparing to Your Explanation of Benefits (EOB)
- Many
patients overlook their EOB, which is essential for identifying
discrepancies between what the provider billed and what the insurance
covered.
- Skipping
Documentation
- Phone
calls, emails, and notes about conversations with billing departments
should always be recorded and saved. Missing documentation weakens
your dispute.
- Assuming
the Provider or Insurer Will Automatically Correct Errors
- Billing
departments and insurers may require you to formally request
corrections. Always follow up in writing.
- Not
Knowing Your Rights
- Patients
unaware of state laws, federal protections like the No Surprises Act,
and insurance policies are at a disadvantage. Knowing your rights
strengthens your position.
- Overlooking
Negotiation Opportunities
- Even
if the bill is technically correct, you may still qualify for financial
assistance, payment plans, or discounts. Don’t assume negotiation
isn’t possible.
- Neglecting
External Resources
- Sometimes
you need patient advocacy groups, state insurance agencies, or
consumer protection organizations to intervene. Failing to use these
resources can prolong or complicate disputes.
Avoid these pitfalls by staying organized, informed, and
proactive. Keep all documents, review bills carefully, and escalate issues
strategically.
Legal Implications of Medical Billing Disputes
Disputing a medical bill is not just a financial matter—it
can have legal consequences and protections:
- Patient
Rights Under Federal and State Law
- Laws
like the No Surprises Act protect patients from unexpected
out-of-network charges.
- States
may have additional consumer protection statutes giving patients
the right to dispute billing errors.
- Timelines
and Deadlines
- Legal
frameworks often define time limits for filing disputes or appeals.
Missing deadlines may weaken your case.
- Impact
on Collections and Credit Reports
- Unresolved
disputes that enter collections can affect credit scores. Documenting and
communicating your dispute formally can help protect your credit.
- Potential
Liability for Misrepresentation
- Providing
false information, whether intentional or accidental, may have legal
consequences. Always ensure accuracy in your documentation.
Practical Considerations When Disputing a Bill
Handling medical billing disputes effectively requires practical
strategies:
- Organize
All Documentation

action can prevent escalation to collections or legal issues. Follow up
regularly and keep a log of communications.
- Leverage
Available Resources
- Use
billing portals, advocacy services, and patient support groups to
help navigate the dispute process.
- Know
When to Escalate
- If
initial discussions fail, consider formal appeals, state insurance
regulators, or patient advocacy agencies.
- Financial
Planning
- Plan
for potential out-of-pocket payments during the dispute. Some
providers offer payment plans or partial payment options while
disputes are ongoing.
Ethical Considerations in Medical Billing
Medical billing is not just a financial or administrative
task—it has ethical implications for both patients and providers:
- Transparency
and Honesty
- Providers
are ethically obligated to bill accurately and transparently.
Patients should also provide truthful information when disputing
charges.

errors can disproportionately affect vulnerable populations.
Ensuring disputes are handled fairly supports equitable access to
healthcare.
- Professional
Responsibility

advocates, and third-party services should act ethically, avoiding
coercion or misinformation while assisting patients in disputes.
Balancing legal, practical, and ethical considerations
ensures that disputes are resolved effectively while maintaining trust,
compliance, and fairness in healthcare.

Future Outlook: What’s Next in Medical Billing Disputes
As healthcare evolves in 2025 and beyond, the landscape of medical
billing and dispute resolution is poised for significant change. Several
trends are shaping the future:
- Digital
Billing Platforms & Automation
Hospitals and insurers are increasingly adopting automated billing systems. While this can reduce human errors, it may also introduce new coding or algorithm-based mistakes. Patients and providers will need digital literacy and proactive monitoring to catch discrepancies early. - Stronger
Consumer Protections
With laws like the No Surprises Act becoming more entrenched, patients will have enhanced legal and financial protections. We can expect streamlined dispute processes and clearer transparency standards from providers and insurers. - AI-Powered
Billing Reviews
Artificial intelligence will play a growing role in detecting fraudulent, duplicate, or inaccurate charges. Future AI tools could alert patients in real-time about potential billing issues before statements are finalized. - Patient
Advocacy Growth
Organizations and advocacy groups are likely to expand services to educate patients, mediate disputes, and push for fair billing practices. Empowered patients will increasingly have the tools and knowledge to challenge errors effectively. - Integration
with Value-Based Care
As the healthcare system shifts toward value-based care, billing may become more transparent and outcome-driven, reducing unnecessary charges and aligning costs with actual services delivered.
The future promises a healthcare billing system that is more
transparent, digital, and patient-centered, but it will still require vigilance,
advocacy, and knowledge to navigate effectively. Staying informed now will
make disputes easier to manage tomorrow.
