Cornerstone Adminisystems Inc

Cornerstone Adminisystems has spent more than three decades doing one thing: getting EMS agencies and ambulance services paid. Based in New Cumberland, PA, this employee-owned medical billing company delivers end-to-end revenue cycle management built exclusively for the EMS and medical transport community. Clients consistently report stronger cash flow, higher collection rates, and a billing process that frees up their staff instead of creating more administrative burden. The company's outsourcing model covers the entire billing lifecycle, from claim submission and coding through payer follow-up and collections. Cornerstone employs NAAC Certified Ambulance Coders, a credential specific to emergency medical services billing, which means claims are coded accurately against the distinct reimbursement rules governing ambulance transport. The process is designed to be exhaustive and persistent, working every account through each payer's requirements rather than writing off difficult claims. Clients also receive customized financial reporting and access to a free financial forecast tool that projects cash flow based on their own data. Cornerstone serves the full spectrum of EMS organizations: rural volunteer departments, busy career agencies, commercial transport providers, and complex hospital-based systems. Their back-office billing services handle the administrative weight of the revenue cycle so that EMS leadership can focus on operations and patient care. Client testimonials point to concrete results, including annual revenue increases and meaningfully better visibility into financial performance. One client reported an increase of over $25,000 per year after switching, while others cited more predictable cash flow and a clearer picture of their bottom line. As an Employee Stock Ownership Plan company, Cornerstone operates with a different kind of accountability than a typical outsourcing vendor. The people processing your claims have a direct stake in the quality of their work. Many staff members come from EMS backgrounds, including EMTs, former EMS managers, certified coders, and documentation specialists. That domain experience reduces the friction that commonly comes with outsourced billing relationships and means client relations staff can speak the same language as the agencies they serve. If you are evaluating ambulance billing companies or looking to improve collection rates on medical transport claims, Cornerstone offers a free financial forecast to show what your revenue cycle could look like under their management.
