Revenue cycle work remains one of the most labor-intensive parts of healthcare. Physical therapy practices face an average claim denial rate of roughly 13%, and nearly three-quarters of those denials must be appealed. Front-desk teams spend ten minutes or more per patient on prior authorization alone, and most practices have had to add administrative staff simply to keep up. Industry analyses estimate that AI and automation in the revenue cycle represent up to $360 billion in potential annual savings. By putting genuinely agentic AI voice to work on this manual burden, Raintree and Spike aim to return that time to care. <\/p>\n
Unlike scripted phone trees, rules engines, or chatbots layered on top of legacy workflows, the technology is genuinely agentic: AI voice agents that understand context, make decisions, and complete multi-step work, not a fixed menu of options. Because the capability is native to Raintree’s EMR rather than a bolted-on third-party layer, the agents act with full clinical, scheduling, and financial context. It is the foundational piece of a broader vision: fully integrated, agentic orchestration across the entire revenue cycle and patient engagement. <\/p>\n
“Getting paid is the hardest, most manual part of running a therapy practice, and voice is where that burden is heaviest. We chose to take on the hardest piece first,” explained Nick Hedges, Raintree CEO. “We are not just optimizing operational efficiency for our clients, we are launching a seismic shift that will slash RCM\u00a0expenses to an estimated 1%.” <\/p>\n
For Raintree’s customers, the change is designed to be additive, not disruptive. Because the AI voice capability is built into the EMR they already use, there is no separate system to buy, integrate, or rip and replace. Practices can expect less manual phone and follow-up work, fewer touches per claim, faster cash, and more time for clinicians and staff to focus on patients. <\/p>\n
“The industry has been flooded with ‘AI’ that is really just rule-based automation or a chatbot. We built something different: voice agents that genuinely reason and execute complex work, end to end,” said Povilas Gudzius, co-founder and CEO of Spike. “Doing that inside the EMR, with full context, is what makes this problem solvable at scale. Joining forces with Raintree allows us to bring autonomous RCM to the therapy market faster and have an impact on millions of patients with our technology.” <\/p>\n
The combined team will continue to expand the capabilities across revenue cycle and patient engagement over time, building toward fully integrated agentic orchestration. Additional details on availability and roadmap will be unveiled at this summer’s TherapyCon in Austin, TX, August 19\u201321. The keynote presentation, “The Dawn of the Autonomous EMR,” will offer attendees an objective look at how AI-enabled operations have real-world impact on efficiency and administrative burden in rehab physical therapy.
