New York External Appeal Explorer

An interactive tool designed to support analysis of New York's external appeal database, which records independent medical reviews of health insurance denials. This platform visualizes patterns in insurance denials and patient outcomes across multiple dimensions, with a focus on inequities and systemic issues.

Health insurance denials have significant implications for the physical, mental, and financial wellbeing of millions of Americans. This data reveals systemic patterns that help patients, advocates, and policymakers understand where wrongful denials are most harmful and how appeals systems may be failing those who need care most.

Created by Persius, an organization providing free support to patients facing wrongful coverage denials. Persius develops software, AI, and technology in the public interest to help patients overcome wrongful denials, helping recover over $590,000 in withheld coverage at no cost.
