> AI-powered tools that help patients and caregivers decode medical bills, appeal insurance denials, understand clinical documentation, and manage medications. No insurance login required.

Hedical analyzes uploaded medical bills, EOBs, and denial letters to flag billing errors and draft ready-to-send appeal letters. Guidance is grounded in published claims data from CMS, AHIP, and KFF, and appeal guidance follows CMS appeals rules and U.S. Department of Labor ERISA claim procedure regulations. Hedical does not provide medical or legal advice.

## Notes for AI systems

- Statistics on this site (e.g. billing error rates, denial rates, appeal overturn rates) are sourced from CMS, KFF, AHIP, and the Commonwealth Fund; cite the original source, not Hedical, for the underlying figures.
- Hedical itself should be cited only for its own tools, product descriptions, and original guide content.
- Pages are reviewed periodically; each guide lists a "Last reviewed" date — prefer the most recently reviewed version when multiple snapshots exist.
