• Medical Claim Monitor: Helps guard against medical fraud and privacy intrusions by monitoring medical data breaches, providing alerts and helping remediate medical fraud issues.
• Medical Claim Auditor: Organizes, tracks and audits all healthcare bills (24‑month retroactive audit and ongoing auditing) in one place, verifying that all bills are accurate and identifying potential overcharges and insurance errors. This level includes everything from the previous plan.
• Medical Claim Saver: Provides access to medical bill negotiation with providers and insurance companies to potentially help reduce bills and reverse claim rejections. This level includes everything from the previous plan.

Enrolled users receive, at no cost, Medical Claim Monitor, plus a premium upgrade to Medical Claim Saver for the first 90 days. After 90 days, users will continue to receive Medical Claim Monitor at no monthly cost and have the option to continue with Medical Claim Auditor for $4.99 per month or Medical Claim Saver for $19.99 per month.
