Rivia Health brings easeful efficiency to healthcare patient payments. We work with healthcare provider organizations to complement their revenue cycle operations and get them paid more while doing less. Rivia Health alleviates staff overwhelm by reducing manual tasks related to outstanding patient responsibility. Our communication and payment platform integrates with the practice management or RCM system to automate billing workflows like appointment and billing reminders, copay or pre-service payments, and payment plan setup. In addition to saving staff time, Rivia Health also improves financial results by communicating more dynamically to patients about balances across text and email and by making it easier for patients to pay across multiple payment methods with a 3-step, no login required process. Our existing customers have described our results as "Outstanding!" with a 90% reduction in outstanding accounts receivable and 75% of payments are made by day 2, before a paper statement would even arrive.
