Revolist

Revolist (the Revolt Health Network) connects patients with professional advocates who specialize in hospital billing disputes and unfair charges. The advocates review bills for errors, challenge excessive markups, and negotiate directly with hospital finance departments. They work on contingency, taking a percentage of savings rather than upfront fees.

This is strongest for significant hospital bills or complex billing situations where you need expert advocacy with institutional weight. Revolist's contingency model means they're motivated to get results, and their experience with hospitals gives them credibility in negotiations. It's less suitable for small charges or disputes you feel confident handling yourself.
