Losing Money on Paper, Carrying the Hospital in Fact: An Orthopedic Service Line Margin Analysis

Question

Alder Bend's quarterly service line report shows orthopedics losing about $1.26 million a year after overhead. A board member has asked whether the hospital should scale the service back. This analysis rebuilds the orthopedic margin in layers, from net revenue by payer through direct variable costs, direct fixed costs and allocated overhead, and finds that, before any overhead is assigned, orthopedics leaves about $7.4 million each year to help pay for the departments every service relies on. Closing or shrinking it would make the hospital's finances worse, not better. All figures are illustrative and cover one fiscal year.

The Layered Margin

Table 1 builds the margin one layer at a time. The service line includes inpatient joint replacement and spine surgery and outpatient orthopedic procedures performed in the hospital's operating rooms: 2,100 cases in all.

Table 1

Orthopedic Service Line Margin by Layer

Per-case net revenue for the total is a weighted average and is rounded.

Reading Each Layer

Revenue varies sharply by payer. A commercial case brings in $24,500 on average, a Medicare case $15,800 and a Medicaid case $9,600. Because implants and variable labor cost about $12,000 per case regardless of payer, the contribution per case ranges from about $12,500 for commercial patients to $3,800 for Medicare and negative $2,400 for Medicaid. Every payer except Medicaid and self-pay covers its variable costs, and commercial cases cover them several times over.

The contribution margin of $13.3 million is the money orthopedics produces after the costs that would disappear if the cases disappeared. Direct fixed costs of $5.9 million, including the navigation system's depreciation, the orthopedic unit's manager and the physician assistants who staff the service, would also mostly disappear if the line closed. After them, orthopedics still contributes $7.4 million.

The final layer is overhead from departments that serve the whole hospital, such as housekeeping, administration, information technology, finance and facilities. The hospital allocates these costs with the step-down method used in the Medicare Cost Report: each overhead department's cost is assigned to the departments it serves in sequence, using statistics such as square feet, hours or full-time equivalents (Reiter & Song, 2021). Orthopedics occupies a large share of operating room hours and inpatient days, so it absorbs $8.65 million. That allocation turns a positive $7.4 million into a loss of $1.26 million.

Why the Fully Loaded Loss Does Not Mean Closing Would Help

Allocated overhead is a way of sharing costs, not a measure of costs that orthopedics causes. If the service line closed, most of the $8.65 million would remain: the hospital would still need its administrators, its information systems, its finance office and its buildings. Only part of it, such as some housekeeping and supply chain work tied to operating room volume, would shrink. If, generously, $1.3 million of overhead went away with the service, closing orthopedics would remove $7.4 million of contribution after direct costs while saving $1.3 million of overhead, leaving the hospital about $6.1 million worse off. The remaining $7.35 million of overhead would then be allocated to the other service lines, and several of them would suddenly show losses too (Cleverley & Cleverley, 2018).

The right question for a service line is whether it covers its own direct costs and contributes to shared costs, and whether that contribution could be increased. By that test, orthopedics is one of the hospital's strongest lines. The service line report should therefore show contribution margin and margin after direct costs on its first page, with the fully loaded figure below them and a note explaining the allocation, so that board members reading the report are not led to the wrong conclusion by its last line.

Where Improvement Would Come From

Two levers would improve the line's results. The first is cost per case. Implants and supplies average $7,900 per case, and orthopedic programs that standardize implant selection across surgeons and negotiate price ceilings with vendors commonly reduce implant costs. A 10% reduction would add about $1.66 million a year to contribution. Variable labor per case can also fall if length of stay for joint replacement continues to shorten and more eligible cases move to the outpatient setting.

The second lever is payment, and it is concentrated. The Medicaid margin is negative, but at 140 cases its effect is modest. The larger exposure is Medicare: at 820 cases, each contributing $3,800, Medicare makes up 39% of cases but only about 23% of contribution. Medicare's payment for joint replacement is fixed by the DRG, so improving that margin means reducing cost per case rather than negotiating price. MedPAC has reported that Medicare margins for many hospitals are negative across all services combined (Medicare Payment Advisory Commission, 2023), which makes cost discipline on Medicare cases a hospital-wide concern.

The Contract That Shapes the Result

One commercial insurer covers about 60% of Alder Bend's commercial orthopedic cases, roughly 490 a year, and pays the highest rates. Its contract expires in 18 months. If that insurer were to negotiate a 10% rate reduction, orthopedic contribution would fall by about $1.2 million a year, more than any cost initiative is likely to recover in the same period. The hospital's managed care team should begin preparing for that negotiation now, using quality and cost data from this analysis to show the value of the program, and the board should track the line on its contribution margin, not its fully loaded result.
