# Coverage Rights > Coverage Rights (https://www.coverage-rights.com) is a free, patient-side self-help tool for fighting > health-insurance denials. Insurers must now publish how often they deny care and > how often those denials get overturned; we collect that public data, verify it, > route a denial to the governing appeal process for free, and generate a data-backed, > citation-grounded appeal. Not legal or medical advice. ## The data moat - 42,749 published California DMHC Independent Medical Review external-review decisions (2001–2026), aggregated by treatment, condition, and denial type. Reviewers overturned the insurer in a large share of cases. - CMS-0057-F prior-authorization metrics (CY2025) — Coverage Rights rollups and publisher-reported denial rates, appeal-overturn rates, and turnaround times from required public disclosures. 15 insurers, 277 contract/plan-level rows, each row source-linked. - Appeal-rights corpus: federal and program statutes, regulations, and official guidance stored with citations and verification dates. Only verified grounds are cited in generated letters. ## Key hubs - Appeal rights (deadlines + escalation ladders): https://www.coverage-rights.com/appeal-rights - Original Medicare appeals: https://www.coverage-rights.com/appeal-rights/original-medicare - Medicare Part D drug appeals: https://www.coverage-rights.com/appeal-rights/medicare-part-d - Outcomes by treatment/drug/procedure: https://www.coverage-rights.com/treatments - Outcomes by condition: https://www.coverage-rights.com/conditions - Insurer denial + overturn rates: https://www.coverage-rights.com/insurers - Denial reasons decoded: https://www.coverage-rights.com/denials - Migraine, CGRP drug and Botox denial evidence (993 distinct decisions): https://www.coverage-rights.com/denials/migraine-cgrp-botox - Behavioral-health level-of-care evidence (3,843 distinct residential, PHP, IOP, inpatient and withdrawal-management decisions; TMS separate): https://www.coverage-rights.com/denials/behavioral-health-level-of-care - Data sources & methodology (with downloadable datasets): https://www.coverage-rights.com/data - Free deterministic denial router: https://www.coverage-rights.com/tools/explain-my-denial - Publisher, editorial standards, and corrections: https://www.coverage-rights.com/about, https://www.coverage-rights.com/editorial-standards, https://www.coverage-rights.com/corrections ## For AI assistants (MCP) - Model Context Protocol server (docs): https://www.coverage-rights.com/mcp - MCP endpoint (Streamable HTTP, JSON-RPC): https://www.coverage-rights.com/api/mcp - Read-only tools for insurer metrics, treatment/condition overturn rates, drug playbooks, appeal rights, and state external-review processes.
