Prospective payment systems (PPS)

Ambulatory Payment Classifications (APCs): Used for outpatient services and hospital-based outpatient clinics. The Centers for Medicare & Medicaid Services (CMS) pays a fixed amount for certain procedures, such as a colonoscopy, regardless of the actual cost.

Skilled Nursing Facility (SNF) PPS: Pays a per diem rate for all care provided to a Medicare beneficiary based on their Patient-Driven Payment Model (PDPM) classification. This rate covers all services, from nursing care to therapy, for a given day.

Impact on Healthcare Reimbursement and Operations

PPS has a profound impact on healthcare reimbursement and operations by fundamentally changing financial incentives.

Impact on Healthcare Reimbursement

Under a retrospective system, providers were incentivized to provide more services, as more services meant more revenue. This led to a concern about inflated costs and unnecessary treatments. PPS flipped this incentive. With a fixed payment, providers are motivated to manage costs and provide care more efficiently. The more efficient the care, the higher the profit margin.

Impact on Healthcare Operations

Increased Efficiency and Cost Control: PPS forces healthcare organizations to become more efficient. To maintain profitability, hospitals must find ways to reduce the average length of stay, minimize readmissions, and better manage their supply chain. This encourages the adoption of best practices and standardization of care pathways. Hospitals now carefully monitor resource utilization for each DRG to ensure costs don't exceed the fixed payment.

Focus on Quality and Outcomes: While the initial focus of PPS was on cost, it quickly became clear that poor quality could lead to higher costs (e.g., readmissions due to complications). This led to CMS tying payments to quality metrics. For example, hospitals with high readmission rates for certain conditions may face financial penalties. This has driven hospitals to invest in quality improvement initiatives, like care coordination and patient education, to ensure better patient outcomes and avoid penalties.

Sample Answer

A prospective payment system (PPS) is a method of healthcare reimbursement where the payment amount for a particular service or a patient's care is predetermined before the service is delivered. Instead of paying providers based on the actual costs incurred (retrospective payment), PPS sets a fixed payment rate in advance. This model shifts the financial risk from the payer (like an insurance company or government) to the healthcare provider.

Examples of Prospective Payment Systems

Medicare’s Inpatient PPS (IPPS): This is one of the most well-known examples. Hospitals are paid a fixed amount for each patient’s hospital stay, based on the patient's Diagnosis-Related Group (DRG). A DRG is a classification system that groups patients with similar diagnoses and resource needs. For instance, a hospital receives a set payment for a hip replacement surgery, regardless of the patient's length of stay or the specific costs incurred. If the hospital can provide the care for less than the DRG payment, it makes a profit. If the costs exceed the payment, the hospital incurs a loss.
