Artificial intelligence is becoming a powerful resource for patients and healthcare providers who are challenging insurance claim denials. Major insurers have faced growing criticism for using AI tools that automatically reject medical claims, often without human involvement. These systems are designed to reduce costs and increase efficiency, but they have raised serious concerns about fairness, patient harm, and lack of oversight.
According to official data, health insurance companies process more than five billion payment claims each year. According to KFF, a healthcare policy organization, over 850 million are refused. Less than 1% of patients file appeals. The process can be confusing, slow, and emotionally draining. As a result, patients often accept the denial and forgo treatment or pay out of pocket.
With the rise of accessible AI tools, that is beginning to change. AI is now helping people generate effective appeals quickly and at little or no cost. One of the leading tools in this industry is Counterforce Health. Founded by Dr. Neal K. Shah, the platform allows users to upload denial letters and medical records. Within minutes, it produces a professionally written appeal letter. The company reports a success rate of about 70 percent. Counterforce is funded by grants and is remain free for public use. Its creators hope to reach underserved communities, especially in rural areas where access to
legal or medical advocates may be limited.
Other platforms are also contributing to this shift. Fight Health Insurance, developed by engineer Holden Karau, enables patients to generate several appeal letters based on the specifics of their case. Karau also built Fight Paperwork, a version designed for doctors. Physicians using the tool have reported that they can now challenge many more denials than before without increasing their workload.
A company called Claimable offers a similar service for a flat fee. Its AI creates customized letters across medical conditions including migraines, autoimmune diseases, and pediatric disorders. Claimable says about 80% of the appeals submitted through its platform are successful.
Many are resolved in less than two weeks. Some startups are integrating these features directly into the administrative systems of hospitals. Waystar, a healthcare technology company, has developed a tool that drafts appeal letters within its billing platform. This innovation is meant to reduce the cost and time associated with appealing denials, which currently costs American providers billions of dollars each year. These tools have already made a difference.
Patients have reported receiving thousands of dollars in reimbursement after submitting AI-generated appeals. Doctors and clinics have found ways to process more appeals in less time. The accessibility of these services is helping to close the gap between large insurance companies and individuals who previously had little chance of successfully challenging a claim denial.
However, challenges remain. Lawmakers in states like California and Connecticut are proposing new laws that would require human review of any AI-generated denial. Some bills also aim to fine insurers if a large number of their denials are later overturned. Advocates argue that these reforms are necessary to protect patients from unfair or careless decision-making by algorithms. AI cannot solve every problem in the healthcare system, but it is already providing critical support to people who might otherwise be ignored. By making the appeals process faster, cheaper, and more accessible, AI is helping restore balance to a system that has long felt one-sided.
