Cornerstone Services

Cornerstone Services is a medical billing company based in Northglenn, Colorado, with 21 years of specialization in physical therapy billing and revenue cycle management. The company was built to give healthcare providers a reliable outsourcing option for the billing side of their practice, so clinical staff can concentrate on patient care while a dedicated back-office team handles the paperwork, follow-ups, and insurance negotiations. The service covers the entire billing cycle. Charges go through scrubbing before being filed electronically each day, which catches errors at the source rather than after a denial arrives. When payers do deny claims, the team follows up daily to resolve them quickly. Aging accounts receive dedicated attention because unresolved claims have a way of quietly disappearing. Patient billing support is also included. Staff explain statements directly to patients, walk them through terms like deductibles and out-of-pocket limits, and handle inquiries that would otherwise burden a practice's front desk. Cornerstone works with physical therapy clinics and healthcare organizations of all sizes, from solo independent practitioners to large, multi-location corporate groups. The company has built long-term client relationships over its two-decade history. Michael Biba, CEO of PEAK Physical Therapy and Wellness, has relied on Cornerstone for revenue cycle management for more than ten years, citing the team's "knowledge, professionalism, and superior results." Communication and transparency are central to how the company operates. Clients receive routine reports reflecting their financial performance at whatever level of detail they need, from a high-level summary to a granular breakdown of claim activity. Monthly or quarterly review meetings give practices a structured place to raise questions, surface concerns, and identify opportunities to improve collections. The team stays current on coding changes, payer policy updates, and regulatory requirements so practices remain compliant without having to track every industry development themselves. For physical therapy providers and healthcare organizations ready to outsource medical billing to a U. S.-based specialist, Cornerstone Services offers a full-cycle, hands-on approach built over two decades in the field. Reach out through their website to discuss your practice's revenue cycle needs.
