We received HITRUST CSF certification demonstrating our technology meets key healthcare regulations and requirements for protecting and securing sensitive protected healthcare information. These third-party audits ensure that healthcare controls, finance, and IT processes meet industry standards and translate into superior quality services.

Peer Reviews are paper-based evaluations prepared by credentialed, independent physicians to establish an informed expert opinion about the appropriateness of care, medical necessity, experimental/investigational, and related issues. With access to a broad nationwide network of board-certified physicians and licensed allied professionals from all major specialties and sub-specialties, we are able to provide our clients the appropriate expertise for a range of review types: prospective, medical-legal, appeal, and peer-to-peer reviews. Final reports are tailored to meet state-specific content and turnaround time requirements, with reports available on the MES or respective client portal.
