AI-Powered Appeals Reverse Insurance Denials at Scale
A new class of startups is automating healthcare insurance appeals, generating letters and filing cases on behalf of patients at speeds and costs that manual work cannot match. The tools sit in a gap between insurers and patients-a space that has traditionally been a two-party transaction.
The opportunity is substantial. Fewer than 1% of patients appeal denied claims. When they do, insurers uphold the original decision more than half the time.
How the Tools Work
Claimable, founded in 2023 by physician Warris Bokhari alongside Alicia Graham and Zach Veigulis (former chief data scientist at the Department of Veterans Affairs), uses a large language model trained on insurance laws, legal precedents and medical literature to generate appeal letters.
The company confined the model to a curated knowledge set to prevent hallucinations. The tradeoff is scope: Claimable currently automates appeals for 28 conditions and 90 treatments. Adding a new condition now takes days instead of months.
The economics favor patients. At $50 per case, the filing fee is negligible against treatments worth thousands. The company reports that roughly 3 in 4 users see their denials reversed.
Counterforce Health operates a similar service at no cost. Its model generates customized appeal letters based on a patient's policy and successful appeals history, and copies state insurance regulators on filings to surface denial patterns. A clinical coordinator at a North Carolina rheumatology practice told NBC News she began receiving same-day and next-day approvals after switching from manual to automated appeals.
Enterprise Deals Drive Scale
The consumer model alone cannot sustain the business. Claimable has begun negotiating deals with pharmaceutical manufacturers and hospital systems to appeal on behalf of denied patients, with four drugmaker agreements already signed.
For drugmakers, the incentive is direct: a denied claim for a branded drug is lost revenue. A successful appeal is a filled prescription. Claimable helped patients in a class action against CVS Health file appeals after the insurer denied prescriptions for the weight-loss drug Zepbound in favor of a competitor.
The company is also exploring a litigation arm to pursue class-action suits when it identifies patterns of wrongful denials across payers.
A Shifting Claims Landscape
Insurers have deployed AI for insurance claims processing to deny coverage faster and defend against fraud. The speed of automated denials has widened the gap between what patients are owed and what they successfully claim.
As denial processes accelerate, the appeal tools entering the market are filling the space insurers and health systems have left open. The revenue cycle that once involved two parties now has three.
