The Onyx Group

The Onyx Group is a healthcare management services organization (MSO) based in Greer, South Carolina, built to give physician practices and health systems a complete administrative infrastructure without the overhead of building one internally. As a joint venture between MUSC Health and a group of independent physicians, the organization combines real clinical perspective with operational expertise, making it a distinctive back office outsourcing partner for healthcare providers across the United States. Revenue Cycle Management sits at the center of what they do. From charge entry and claims submission through denial resolution and payment reconciliation, The Onyx Group manages the full RCM workflow so practices can focus on care delivery rather than billing operations. Information Technology and EMR Support helps clients implement and maintain their electronic medical record systems, while Credentialing and Licensing services take the administrative weight off providers who need to stay current with payer enrollment and state requirements. On the business operations side, they provide Finance and Accounting, Human Resources, Payroll Processing, and Purchasing and Procurement, effectively functioning as a full back office outsourcing team for practices that want enterprise-level support at a manageable cost. Their Clinical Informatics and Business Intelligence and Analytics services help practices turn their own data into better operational decisions, something that smaller independent groups often lack the internal capacity to do on their own. For practices at an earlier stage, the organization also offers Practice Start-Up services, helping new physician groups get up and running with the right administrative foundations in place. Practice Management Consulting and Strategic Planning round out the portfolio for organizations navigating growth, restructuring, or competitive market pressures. This breadth is what positions The Onyx Group as a single-source solution rather than a niche BPO company that USA healthcare providers would need to supplement with additional vendors. The clients they serve are primarily independent physician practices, specialty groups, and healthcare organizations across Upstate South Carolina, with a model designed to scale across different practice sizes and specialties.
