Upon successful completion of this module, the student will be able to understand and calculate Medicare payments for hospital and physician services, discuss the characteristics of major hospital and physician payment systems, compare prospective and retrospective payment mechanisms, analyze major payment reform initiatives in the Patient Protection and Affordable Care Act, and reflect on course concepts related to healthcare reimbursement systems.

The module provides an overview of hospital payment systems, focusing on the Medicare prospective payment system (PPS) based on diagnosis-related groups (DRGs). Private payers often emulate Medicare’s DRG-based approach, which classifies hospital inpatient cases into approximately 500 categories based on diagnoses, procedures, age, sex, discharge status, and comorbidities. For example, DRGs include categories such as craniotomy, pancreatic and liver shunt procedures, kidney transplants, and post-operative infections, each assigned a case weight that influences reimbursement.

The Medicare PPS comprises three main elements: operating payment, capital payment, and outlier payment. The operating payment is computed by multiplying the DRG relative weight by a standardized amount adjusted for labor and non-labor costs, with additional adjustments for indirect medical education and disproportionate share hospital (DSH) payments. Outlier payments are extra reimbursements for cases requiring extraordinary resources, based on specific criteria and calculations.

Capital payments began in 1992 to reimburse hospitals prospectively for capital costs, calculated by multiplying the DRG relative rate with the federal capital rate, adjusted for geographic and cost-of-living factors, and considering hospital-specific factors. Outlier payments in this context serve as supplementary compensation for unusual cases with high resource utilization.

Turning to physician services, Medicare utilizes the resource-based relative value scale (RBRVS) to determine reimbursement rates. Each procedure code (CPT code) is assigned three types of relative value units (RVUs): work RVU, practice expense RVU, and malpractice RVU. These RVUs quantify the physician’s effort, non-physician costs, and malpractice insurance expenses, respectively. The total RVU for a procedure is obtained by summing these components and multiplying by regional geographic cost indexes and a conversion factor, which results in the final payment amount.

For example, if a procedure’s RVUs are combined to total a certain value, the application of the regional cost indexes and the conversion factor yields a Medicare-approved payment rate—illustrated here as approximately $5,847.42. Physicians are classified as participating or non-participating, affecting their billing and reimbursement processes. Participating physicians agree to accept assignment on all cases, bill Medicare directly, and receive 80% of the approved fee from Medicare, with patients responsible for the remaining 20%. Non-participating physicians may bill patients directly on a case-by-case basis, sometimes up to 115% of the Medicare-approved fee (limiting charge), and the reimbursement process involves Medicare reimbursing either the patient or paying 80% of the fee depending on the physician’s participation status.

Healthcare reimbursement systems play a crucial role in managing the economics of medical services, impacting providers, payers, and patients alike. The Medicare program, as the largest public insurer in the United States, exemplifies a structured approach to hospital and physician payment systems designed to promote efficiency, control costs, and ensure access to necessary services. Understanding these systems is vital for healthcare professionals, policymakers, and administrators striving to navigate and reform the complex landscape of healthcare financing.

The hospital prospective payment system (PPS), introduced by Medicare, utilizes diagnosis-related groups (DRGs) to classify inpatient hospital cases based on anticipated resource use. This classification system aims to create predictable, fixed payments for services, encouraging hospitals to optimize resource utilization while maintaining quality care. Each DRG encompasses numerous diagnoses and procedures, with case weights reflecting the relative costs associated with each category. For example, complex procedures like craniotomies or organ transplants have higher case weights, resulting in higher reimbursements. The foundation of Medicare’s hospital PPS involves calculating the operating payment, which multiplies the DRG relative weight by a standardized amount, adjusted for labor and non-labor costs, regional wage differences, and hospital-specific factors such as indirect medical education and DSH payments. Capital costs, reimbursed prospectively since 1992, consider the hospital’s investments in infrastructure and equipment, calculated through a similar formula integrating geographic and economic adjustments.

Outlier payments serve as critical supplements to base payments, providing additional funds for cases with extraordinary resource demands. These adjustments are essential for protecting hospitals against financial risk from unpredictable, high-cost cases, thereby maintaining access to care, especially for vulnerable populations. The overall payment methodologies aim to balance cost control with equitable compensation, addressing the diverse needs of hospitals across various regions and specialties.

In the domain of physician services, Medicare’s adoption of the Resource-Based Relative Value Scale (RBRVS) has revolutionized how physicians are reimbursed. Unlike the DRG system, RBRVS assigns relative value units (RVUs) to each CPT code, reflecting the effort, skill, practice expenses, and malpractice costs associated with individual procedures. The total RVU count for a procedure is then multiplied by regional cost indexes and a national conversion factor, resulting in the final payment amount. This approach ensures that reimbursement levels are sensitive to regional economic variations and the complexity of medical procedures.

Physicians’ participation status influences billing and reimbursement. Participating physicians accept assignment, bill Medicare directly, and receive 80% of the approved fee from Medicare, with the patient responsible for the remainder. Non-participating physicians may choose to accept assignment or not, altering their billing practices and reimbursement rates. Accepting assignment means billing Medicare directly, which then reimburses 80% of the fee, while not accepting means billing the patient directly, with Medicare reimbursing the patient for 80% of the fee initially billed. These distinctions impact the financial transactions and the level of patient responsibility.

Overall, the evolution of healthcare payment systems reflects a continuous effort to balance cost containment with quality assurance. Medicare’s systematic approaches—PPS for hospitals and RBRVS for physicians—serve as models and benchmarks for private insurers and health policy reforms. As healthcare costs escalate, understanding and refining these mechanisms remain essential to implement future reforms that enhance efficiency, reduce disparities, and improve patient outcomes.

The Affordable Care Act (ACA) introduced numerous initiatives to reform healthcare payments, emphasizing value-based care, accountable care organizations (ACOs), and bundled payments. These reforms aim to shift focus from volume-based to value-driven reimbursement, encouraging providers to deliver high-quality, cost-effective care. The ACA also promotes transparency and patient engagement, integral to modern healthcare financing strategies.
