viaMD is a surgical supply chain "software as a service" company. We streamline today's paper based, disconnected surgical supply chain by connecting surgeon office, hospital, payer, and medical device company stakeholders online in a collaborative workflow with shared, actionable information at each process step. We start with collaborative surgery planning including surgery scheduling, physician's admitting order, payer prior authorization, and material selection. We integrate surgery planning with OR supply chain management including inventory and order management, procure to pay, and vendor managed invoice incentives based on hospital performance. As a result, users are more productive, stakeholders can bill accurately and eliminate hard costs, and patients enjoy a better coordinated surgical experience.
