For provider organizations that lose revenue and create financial distress by billing high out-of-pocket costs to patients with expensive diseases like cancer, Vivor offers PayRx, financial workflow technology that reduces patient responsibility by maximizing the use of assistance programs. PayRx automatically checks patient eligibility for generous but underused financial assistance programs, significantly increasing enrollments. When providers enroll more patients in assistance programs, write-offs/charity decline and patients experience less financial distress. PayRx has helped over 25 hospitals and private practices to secure an average of nearly $5,000 in financial assistance across hundreds of patients. In an IRB-approved pilot study completed at the Duke Cancer Institute, we demonstrated that information about assistance programs improves patient financial knowledge and addresses treatment-related financial concerns. Our API-enabled offering integrates into pre-service and patient collection workflows through partnerships with leading revenue cycle and EHR technology vendors, enabling turnkey financial assistance search
