This Spreadsheet Is Only An Estimate Of Payment It Is Not

This document provides an illustrative example of how Medicare payments are calculated for a specific hospital case, emphasizing that the figures are estimates and should not be relied upon for exact payment calculation. The example focuses on a hospitalization with a Medicare-approved charge of $200,000 for a procedure classified under DRG 498 (Spinal Fusion Posterior) at a large urban hospital in the San Francisco, California CBSA, discharged on or after October 1, 2006.

To facilitate understanding of the payment process, the example details the various assumptions, standardized amounts, adjustment factors, and calculation steps used by Medicare to determine hospital reimbursements, including both operating and capital payments, as well as outlier adjustments for exceptionally costly cases.

The example highlights the importance of multiple components involved in Medicare's reimbursement methodology, including DRG relative weights, geographic wage indexes, cost of living adjustments, and various adjustment factors such as IME (Indirect Medical Education) and DSH (Disproportionate Share Hospital). Moreover, it demonstrates how Medicare calculates outlier thresholds and payments for cases where costs surpass predefined fixed loss thresholds.

Medicare's inpatient prospective payment system (IPPS) is designed to reimburse hospitals based on predetermined rates, adjusted for case severity, hospital location, and other factors. The process involves multiple detailed steps that incorporate standardized amounts, geographic adjustments, and various other modifiers, ensuring that hospitals are fairly compensated while controlling costs. This paper explores the methodology through an example of a hypothetical case, illustrating how Medicare calculations are performed from initial charges to final reimbursements.

The example revolves around a hospital at a large urban area with Medicare-approved charges of $200,000. The case involves a patient discharged after a spinal fusion procedure classified under DRG 498, which has a relative weight of 2.9896. The calculation begins with identifying the standardized amounts for labor-related and non-labor-related costs, adjusted by the San Francisco CBSA wage index and geographic cost adjustments. The labor-related component is set at $3,397.52, while the non-labor component is $1,476.97, both multiplied by their respective geographic adjustment factors.

Next, the calculation involves applying a series of multipliers for indirect medical education (IME) and DSH adjustments, which account for hospitals serving a higher proportion of Medicaid patients or having teaching programs. These adjustment factors are incorporated into the calculation of both operating and capital reimbursements, reflecting the increased costs associated with these hospitals.

The Medicare payment formula begins by calculating the Federal Rate for Operating Costs. This involves multiplying the DRG relative weight by the sum of the labor and non-labor standardized amounts, adjusted for the wage index and cost of living adjustment, then further increased by the IME and DSH factors. The resulting figure in the example is approximately $24,407.58. Similarly, the Federal Rate for Capital Costs is computed by multiplying the DRG relative weight by a federal capital rate, then adjusting for urban add-on factors, geographic cost adjustments, and the COLA, resulting in roughly $1,923.47.

Following the determination of federal rates, the hospital’s billed charges are used to estimate actual operational and capital costs based on the respective charge ratios. For example, the billed charges of $76,000 are multiplied by the operating cost to charge ratio (0.38) to derive operating costs of $28,880, while capital costs are based on an 0.04 ratio, resulting in $3,040.

Subsequently, threshold calculations are performed to determine outlier payments. The fixed loss thresholds are adjusted based on the hospital's geographic location, wage index, and urban status. The operating outlier threshold, for instance, is approximately $54,929, and the capital outlier threshold is approximately $5,153, both derived from a fixed loss amount of $24,485. These thresholds are critical because when total costs (operating plus capital) exceed the sum of the respective thresholds, the hospital becomes eligible for additional outlier payments.

The final steps involve assessing whether actual costs surpass these thresholds. If so, the hospital receives additional payments calculated as the excess costs multiplied by a marginal cost factor, typically less than 1 to contain costs. The example shows an operating outlier payment of approximately $16,857 and a capital outlier payment of about $2,277, provided the total too-costly case exceeds thresholds.

In conclusion, this example demonstrates the complexity and granularity of Medicare's payment system. It emphasizes how multiple factors—geographic adjustments, case severity, hospital characteristics—are integrated into a comprehensive formula. The detailed calculation process underscores the importance of accurate data and standardized methodologies to ensure equitable and cost-controlling reimbursement for hospitals.
