Finding Success in Value-based Payment
Value-based payment (VBP) ties physician payment more closely to improving patient outcomes and reducing costs when compared to the volume-based, fee-for-service (FFS) system. Success in a VBP model relies on identifying and prioritizing patients at risk for poorer health outcomes and directing preventive and other health care services to those patients.
There are two mechanisms to assign patients to a physician or practice during the course of the year: attribution and empanelment.
Commercial and government payers assign patients to physicians or practices who are held accountable for their care and associated costs. This process is known as attribution.1 As VBP models evolve, attribution will continue to determine payment to primary care physicians in these models. Identifying which payers have attributed which patients to your practice, and the impact of each VBP program your practice participates in will help your practice effectively allocate resources to improve care and reduce costs.1 Payers use two types of attribution: prospective and retrospective. Prospective attribution allows physicians to know which patients are assigned to them at the beginning of the measurement year for the next 12-24 months.1 However, this attribution list may only be updated annually or quarterly, based on the payer contract. Retrospective attribution alerts physicians of their assigned patients at the end of the year, and payers measure performance based on a look-back period—typically the previous 12-24 months.1 Attribution methodologies differ by payer and contract. However, some combination of patient choice and/or a claims-based algorithm is typically used to assign patients to physicians. These include:
• Voluntary attribution: Process in which patients select their primary care physician
• Claims-based attribution: Methodologies differ for this type of attribution, but some payers assign patients based on which physician
