Oxford Physical Therapy replaced its homegrown EHR and billing platform with the AI-enabled Athelas practice management system across its 11 locations in February 2026, and the move has produced a 0.5% end denial rate and more than $250,000 in recovered revenue. The therapy provider made the switch after concluding its legacy system couldn't keep pace as AI became increasingly central to both clinical documentation and revenue cycle management.
"We foresaw that AI was going to be a big piece of future advancement, both for documentation but also for RCM/billing," said Matt Ernst, partner and physical therapist at Oxford Physical Therapy. "We knew that payers were using those systems, and we were getting burdened with more paperwork, authorizations and mounting requests to get paid."
Oxford evaluated several vendors before choosing a staged rollout, first implementing AI scribing and revenue cycle management, then moving to the full practice management platform. Ernst credited extensive testing, workflow validation and on-site support with making the transition smoother than previous EHR changes.
"We have been through EHR changes several times before, but the pre-planning here made a huge difference," he said, pointing to training materials, videos and validation testing.
Revenue recovery and denial reduction
Oxford reports faster claims submission and reimbursement, fewer prior authorization denials, and the $250,000-plus in recovered revenue. For Ernst, that last figure matters most.
"The recovered revenue is the most significant, as that is cash in the door," he said. "As a smaller company, that definitely is noticeable and impactful."
He attributes the gains to better visibility into claims, stronger documentation from the AI scribe, and the ability to spot denial trends quickly. "One denial can be leveraged to avoid future ones," he said. Professionals working in revenue cycle management can see how this pattern applies beyond physical therapy in this AI for Medical Billers course.
Clinicians get time back
The AI scribe has changed daily work for clinicians, Ernst said, allowing them to focus on patients rather than keyboards. Documentation happens "in the background" while therapists interact with patients "uninterrupted by pointing/clicking/typing."
"Our clinicians are happier no doubt," he said. "I have had physical therapists with over 15 years of experience tell me that they now remember why they wanted to be a PT again."
Therapists are finishing workdays earlier instead of completing stacks of notes during lunch breaks or after hours. Documentation quality and timeliness have improved while the practice has maintained its 4.9-star Google rating.

Recruiting and retention benefits
The technology has also become a recruiting tool. Ernst said students who completed internships at Oxford saw AI-assisted documentation firsthand and later returned seeking full-time jobs.
"Most recently we hired three previous students who sought us out after completing school," he said. Demonstrations at career fairs and presentations to PT and PTA programs also generated interest in the practice's technology-enabled workflow.
Outside the clinic, AI-supported front-desk workflows, patient kiosks and the patient portal reduced administrative burden and contributed to improved retention among front-office staff.
Why this matters for managers
For practice managers weighing an EHR replacement, the Oxford experience offers a concrete reference point. The transition showed that a staged rollout with dedicated training time can cut friction, and the measurable results - a 0.5% denial rate and six-figure revenue recovery - give a baseline for setting expectations with leadership. Managers should request vendor-run validation testing and on-site support as negotiating terms, since that preparation was central to avoiding disruption across 11 locations.
