How to Fight Health Insurance Denials Using AI: A Complete Guide from Mayo Clinic Experts
Health insurance denials can feel like a devastating blow when you're already dealing with a serious medical condition. But according to groundbreaking research from Dr. Nancy Wei and Lauren Rhodess at the Mayo Clinic, artificial intelligence is revolutionizing how patients can fight back and win.
In a comprehensive presentation for the Prostate Cancer Research Institute (PCRI), these healthcare professionals revealed a shocking statistic: less than 1% of denied health insurance claims are actually appealed by consumers in the general marketplace. Yet when appeals are filed properly, success rates can reach 50% or higher.

Patients Feel Powerless
"We understand that unfortunately these denials can be intimidating and make you feel powerless," Dr. Wei explained at the beginning of the presentation. "That inspired Nancy and I to make this talk so that patients like you are familiar with the tools you can use to help write appeals for your insurance denials."
The statistics are sobering. Insurance companies spend approximately $20 billion annually fighting denials. Meanwhile, the vast majority of patients simply give up when they receive that dreaded denial letter, assuming there's nothing they can do.
But there is something you can do and it doesn't require legal expertise or thousands of dollars in professional fees.
Enter AI: Your Personal Appeal Assistant
The Mayo Clinic team focused on three major AI chatbots that are completely free to use: ChatGPT, Google Gemini, and Claude. These aren't simple customer service bots—they're sophisticated large language models (LLMs) that can understand complex medical situations and craft compelling, professional appeal letters.
"Think of them as highly advanced research assistants that you can access through your computer or smartphone," Rhodess explained.
ChatGPT: The Recommended Starting Point
Available at chat.openai.com, ChatGPT is the most accessible option because you don't even need an account to begin using it. Just navigate to the website and start asking questions.
Key advantages include:
- Internet connectivity with source citations
- Ability to remember past conversations
- Most widely recognized with abundant support resources
- Can handle iterative requests (you can ask it to modify or add to your letter)
"I would personally recommend starting with ChatGPT," Rhodess advised. "Since it's the most well-known model, even if you get really confused, there are a lot of resources out and available."

Google Gemini: The Integration Specialist
Found at gemini.google.com, Gemini excels at integrating with other Google services like Gmail and Google Docs. This means you won't have to worry about copying and pasting your final document into a Word file.
The newest Gemini models are connected to the internet and can provide source links, though some older versions may only have information current through January 2025.
Claude: The User-Friendly Alternative
Available at claude.ai, Claude offers an approachable interface with physical buttons that let you adjust writing style with a single click. You can choose a more creative, human-like approach or a research-heavy, straightforward tone.
While Claude isn't connected to the internet (meaning it can't link sources directly), it can process larger amounts of text than other models—useful when dealing with lengthy medical records.
Understanding Your Denial Letter: The Critical First Step
Before you can write an effective appeal, you need to thoroughly understand why your claim was denied. Every denial letter contains three essential components that you must identify:
1. The Denial Statement
This typically appears early in the letter in plain, unmistakable language: "Your coverage for your requested service has been denied" or "Your claim for a medical service has been denied."
2. The Reasons for Denial
This is absolutely critical, your appeal must directly address every specific reason given. Dr. Wei emphasized: "This is the most critical part of the letter because your appeal must directly address this specific reason."
Common reasons for prostate cancer treatment denials include:
Medical Necessity Issues: The insurance company claims your PSA isn't high enough, or that conventional imaging should be tried first before approving advanced PET scans.
Unapproved or Experimental Treatments: Newer therapies like certain genetic tests or cutting-edge medications that the insurance policy hasn't caught up with yet.
Prior Authorization Failures: Your doctor's office may have forgotten to submit required paperwork, or insufficient clinical information was provided.
"The reasons for denial might not be as clear-cut as in the denial statement," Dr. Wei warned. "They can come in many different forms. The reasons might be presented in a list format or they might be hidden within other technical language within the denial letter."

3. Appeal Rights Information
This section outlines how to appeal the decision, including crucial deadlines. Most insurers require appeals within 1 to 6 months of the denial date.
"Always read the entire letter carefully," Dr. Wei stressed. "The real reason for your denial might be buried in the middle of a paragraph or within some confusing and complicated language. Sometimes there are multiple reasons given and you'll need to address each one in your appeal letter."
Preparing Your Documentation
The quality of your appeal depends entirely on the quality of information you provide to the AI. Dr. Wei recommends gathering these materials before you begin:
Diagnostic Information:
- Initial diagnosis date
- Cancer stage and Gleason score (for prostate cancer)
- Complete PSA history over time
Treatment and Imaging History:
- Chronological list of all treatments, surgeries, radiation therapy, hormone therapy, or other interventions
- Reports from all previous scans (MRIs, CT scans, bone scans, PET scans)
- Your doctor's clinical notes
Supporting Evidence:
- Peer-reviewed medical journal articles showing the requested service is standard care
- Medical association guidelines, especially from the National Comprehensive Cancer Network (nccn.org)
- Studies demonstrating why the denied service is the appropriate next step
"Think of your health records a lot like your tax returns," the presentation advised. "Having to collect years of records in a short amount of time might be overwhelming, but preventatively keeping well organized records for yourself or with the help of a loved one will make this entire process much easier."
The Two Approaches: Full Letter vs. Template
AI chatbots offer two distinct methods for creating your appeal, depending on your comfort level with sharing personal information:
The Full Appeal Letter Approach
With this method, you provide all your personal medical details directly to the AI, which then generates a complete, customized letter specific to your situation. This is the fastest approach and produces the most tailored result.
The Template Letter Approach
If you're uncomfortable sharing personal health information with an AI (remember, real people may review conversations for training purposes), you can request a generic template with blanks to fill in yourself.
"We totally get it if you're a bit hesitant to share personal details with an AI device," Rhodess acknowledged. "You can still use AI to help you out when you are denied coverage, regardless of if you want to share your personal health details with an AI chatbot."

"There's no right or wrong answer when using AI chatbots as long as you are careful in double-checking the letter," she continued. "You can always find whatever method works best for you and run with it."
Crafting Your Prompt: What to Tell the AI
The presentation provided a structured format for creating an effective prompt. The key principles are:
Be Specific: Talk to the AI like it's a person. Use full sentences and be as detailed as possible. Instead of "appeal letter prostate cancer," write something like: "I am diagnosed with prostate cancer. Here are some exact details. Please write an appeal letter for my insurance denial."
Provide Context: Include all the documentation you've gathered—diagnostic information, treatment history, imaging results, and supporting medical literature.
Specify Format: Request a formal letter format with your information at the top, the insurance company's address, proper subject lines, and your doctor's information.
Indicate Tone: Appeals should be professional, fact-based, and respectful, but still assertive. You can directly ask the AI for this tone.
"Quality in, quality out," Rhodess emphasized. "Your appeal letter rests on the information that you can get and tell the AI. By compiling important information and presenting that clearly to your AI, you are setting yourself up for success."
Real Results in Under One Minute
During the presentation, Rhodess demonstrated the process in real-time using ChatGPT. After pasting in a completed prompt with sample patient information, the AI immediately began generating a professional appeal letter.
The result included:
- Proper formal letter formatting with addresses and subject lines
- Clear paragraphs detailing medical history, treatments, and responses to therapy
- Specific sections on imaging history and current medical status
- Medical literature references and evidence-based arguments
- Footnotes citing NCCN guidelines and peer-reviewed studies
When Rhodess requested additional details about chemotherapy treatment, ChatGPT instantly updated the letter while maintaining the same professional format—demonstrating the "iterative capabilities" that allow you to refine your letter through conversation.
"ChatGPT will usually offer some helpful services after fulfilling your original prompt," Rhodess noted. "When you generate your own letters, you can absolutely make use of these services."
The entire process—from initial prompt to fully cited, professionally formatted appeal letter—took less than one minute.

Protecting Your Privacy and Verifying Information
While AI tools are powerful, the Mayo Clinic team emphasized several important safety considerations:
Privacy First
"You should always only share information that you are comfortable sharing with the AI," Rhodess cautioned. "Real people might read and review the conversations that you have with the AI for training and refining purposes."
Never share information you're uncomfortable with, including:
- Your full name and address
- Insurance ID numbers
- Social security numbers
- Any other personally identifiable information
"You can always edit and add more information to your appeal letter after the AI has generated the letter," she added.
Verify Everything
"AI chatbots can hallucinate information that does not exist and is not true at all," Rhodess warned. "Sometimes this means that they make up false sources or present false conclusions in a very convincing tone."
Always:
- Carefully read through everything the AI tells you
- Click on source links to verify they're real
- Research the studies and arguments provided
- Confirm that cited guidelines actually support your case
"We want to stress that you should always carefully read through everything your AI chatbot tells you and do your own research on the sources and arguments that it provides."
Beyond AI: Building Your Support Team
While AI is a powerful tool, the Mayo Clinic experts emphasized that it shouldn't be your only resource. Multiple sources of help can work together:
Your Medical Team: Physicians, nurses, and clinic staff can provide supporting documentation and may be willing to write their own letters or participate in peer-to-peer reviews with the insurance company.
Patient Advocate Foundation: This nonprofit organization offers free assistance with appeals Monday through Friday.
American Cancer Society: Provides comprehensive appeal information and can offer guidance through their helpline.
HR Departments and Unions: If your insurance is through your employer, these resources can often intervene on your behalf.
Social Workers: Many hospitals and clinics have social workers who specialize in helping patients navigate insurance issues.
Peer-to-Peer Reviews: Some physicians will get on the phone directly with insurance company medical directors for 5-10 minute conversations that frequently result in reversed denials.
"Writing an appeal letter with AI won't hurt your chances of getting help from other sources like your physician, HR department, union, social workers, or nonprofits," Dr. Wei explained. "Writing your own appeal letter with AI can be a useful tool for sources of help to use as a jumping off point for their own supporting appeal letters."

Understanding the Types of Appeals
The presentation clarified that there are two main types of insurance denials you might face:
Prior Authorization Denials: The insurance company refuses to approve a treatment or test before you receive it. For example, they won't approve a PSMA PET scan your doctor has ordered.
Claim Denials: You've already received the service, but the insurance company refuses to pay for it, leaving you with a potentially enormous bill.
Both types can be appealed using the same AI-assisted approach. The key is addressing the specific reasons for denial with evidence-based arguments supported by medical literature and clinical guidelines.
The Power of Guidelines and Evidence
One of the most effective strategies highlighted in the presentation was referencing established medical guidelines, particularly from the National Comprehensive Cancer Network (NCCN).
"If you tell the insurance company that this is what these guidelines say, a lot of times they can't do anything about it," the moderator noted. "They've got to follow it. That's enough evidence."
The NCCN website (nccn.org) offers free access to:
- Comprehensive patient resources
- Clinical practice guidelines for various cancer types
- Evidence-based treatment protocols
Creating a free account takes about 30 seconds and provides access to authoritative information that insurance companies generally must respect.
"I can't tell you how many clinicians I've talked to who said the moment I put NCCN guidelines or the patient does in the appeal letter, it's immediately reversed," the moderator shared.
Real World Success Rates
While the overall appeal rate is shockingly low (less than 1% in the general marketplace, rising to 9-11% for Medicare), the success rate for those who do appeal is encouraging.
"When people appealed it regardless of the method, I was looking at 50% in a lot of cases get reversed," the moderator reported. "When someone actually decided to be the squeaky wheel, they won the appeal."
This data reveals a critical insight: insurance companies are counting on patients not to appeal. When patients do push back with well-crafted, evidence-based arguments, they frequently succeed.

Key Principles for Success
Dr. Wei and Rhodess concluded their presentation with essential guidelines for effective appeals:
Move with Organized Speed: Don't miss deadlines, but take time to compile thorough documentation.
Move with Absolute Confidence: You have the right to appeal, and evidence-based medicine supports your case.
Work with Your Entire Medical Team: Coordinate with doctors, nurses, social workers, and other professionals.
Use All Available Free Resources: From AI chatbots to patient advocacy organizations to medical association guidelines.
Be Kind, Polite, and Evidence-Based: Professional, respectful communication combined with solid medical evidence is most effective.
Follow Procedures and Keep Records: Document everything you submit and maintain copies of all correspondence.
"The squeaky wheel wins the appeal—as long as you're kind and polite," the moderator emphasized. "We're not saying you should be a pain. We're saying you should stick up for your rights, use all your avenues, but remain professional and respectful."
A Message of Hope
Perhaps the most important message from this groundbreaking presentation is one of empowerment.
"If you are denied insurance coverage, we want you to know that there are options available to appeal," Dr. Wei concluded. "While denials are very difficult to receive and can be very challenging to navigate, they do not spell the end of your care."
The combination of AI tools, proper documentation, medical evidence, and persistence creates a powerful formula for overturning unjust denials.
"We believe that you all as patients or loved ones are powerful forces in the care that you all receive," Dr. Wei said. "Making appeal tools more accessible and personalized to your needs is a great way to amplify your voice in the healthcare process."
