The continuous rise in national healthcare expenditures has prompted a widespread search for alternative payment methods. This led to value-based care, which links provider reimbursement to the quality and outcome of patient care rather than the quantity of services delivered. The Global Payment Model is a comprehensive alternative payment system designed to transform how providers are compensated. It aligns financial incentives with the overall health of a defined patient population.
Defining Global Payment as a Healthcare Model
A Global Payment Model is a prospective reimbursement arrangement where a provider organization receives a single, fixed budget to cover all or most medical services for a specific group of patients over a set period, typically one year. This method shifts from paying for individual services to paying for the total care of a population. The payment is usually calculated on a per-member, per-month basis (global capitation), regardless of patient utilization within that period.
This structure requires the provider organization to manage all associated costs within the established budget. If the provider delivers high-quality care efficiently and costs are lower than the budget, the organization keeps the surplus, often called shared savings. Conversely, the provider assumes financial risk if the total cost of care exceeds the global budget. This financial accountability incentivizes careful resource management and the prevention of costly medical events.
How Global Payment Differs from Fee-for-Service
The difference between the Global Payment Model and the traditional Fee-for-Service (FFS) model lies in what they reward. FFS pays a separate fee for every service rendered (e.g., an office visit or a procedure), structurally rewarding a higher volume of services. The Global Payment Model rewards efficiency and effectiveness by incentivizing providers to manage the health of their population within a fixed financial boundary.
The timing of payment also differs. FFS is retrospective: the provider delivers the service first and is paid after the fact based on submitted claims. The Global Payment Model is prospective, with the budget paid to the provider organization before services are delivered. This upfront payment gives the provider flexibility to invest in non-traditional services, such as care coordination, without needing to bill for them.
A further distinction is the placement of financial risk. Under FFS, the financial risk for high utilization and excessive spending rests almost entirely with the payer (e.g., the insurance company or government program). The Global Payment Model shifts a significant portion of that financial risk onto the provider organization, such as an Accountable Care Organization (ACO). This transfer of risk drives providers to focus on population health management to remain financially solvent.
Structural Components of Implementation
The implementation of a Global Payment Model hinges on structural components that ensure equitable payment and quality outcomes. A preliminary step involves accurately defining and attributing a patient panel to the participating provider group. In many models, such as those utilized in Centers for Medicare & Medicaid Services (CMS) initiatives like ACOs, patient attribution is determined based on where patients receive the plurality of their primary care services.
Once the population is defined, the global budget is set by establishing a benchmark, often based on the historical spending data of that patient population, adjusted and trended forward. This historical cost base is refined through risk adjustment, a mechanism for ensuring fairness. Risk adjustment uses specific patient information (e.g., diagnosis codes and demographic factors) to accurately gauge the overall sickness or complexity (acuity) of the provider’s attributed patient panel.
This adjustment mechanism increases the per-member-per-month payment for organizations caring for sicker patients, removing the incentive for providers to avoid high-need individuals. Payment is also contingent on the provider meeting specific quality metrics, ensuring that cost control does not lead to withholding necessary care. These quality benchmarks often include measures for preventative screenings, chronic disease management, and hospital readmission rates, balancing financial accountability and patient well-being.
Primary Systemic Goals of the Model
The shift to a Global Payment Model is intended to achieve systemic transformations in healthcare delivery. A primary goal is to foster coordinated care by financially motivating providers across different specialties and settings to communicate effectively. Because the provider holds the budget for the entire episode of care, they are incentivized to manage the patient’s journey efficiently, reducing fragmentation and redundant testing.
Another intended outcome is the reduction of unnecessary utilization of medical services. By eliminating the FFS incentive to perform more services, the model removes the financial reward for marginal or low-value tests and procedures. This encourages clinical decision-making based on patient need rather than volume targets.
Since the provider organization assumes the financial risk, there is an incentive to invest more heavily in preventative care and primary services. Keeping the patient population healthy and out of the hospital is the most effective strategy for staying within budget. This directs resources toward early intervention, chronic disease management programs, and wellness initiatives, shifting the focus from sickness treatment to health maintenance. Finally, the model provides payers and providers with a fixed, predictable cost structure, allowing for more reliable financial planning and budgeting.
