Value-based care (VBC) is a payment model in which providers are reimbursed based on patient health outcomes and cost efficiency rather than the volume of services delivered. Under the traditional fee-for-service model, a provider is paid a set rate for each procedure or visit regardless of whether the patient’s condition improves. Under value-based reimbursement, payment […]

In-house credentialing costs a medical practice $75,000 to $100,000 per year once salary, benefits, payroll taxes, software, and management oversight are fully accounted for. That figure surprises most practice administrators who assume handling credentialing internally is the lower-cost option. Outsourced credentialing services typically run $100 to $300 per application. That’s also per provider, per payer […]
