A few service lines fund the hospital. Most of the others run at a loss.

Hospitals rarely lose money evenly. A handful of high-margin procedures quietly carry the rest, and almost nobody can name them with confidence. Once cost follows the patient instead of the department, the cross-subsidy becomes visible, and so does the decision it forces.

In short

In a typical hospital, 30 to 40 percent of services are delivered below cost and cross-subsidised by a smaller number of high-margin procedures. Procedure-level margins range from minus 40 to plus 60 percent within the same hospital. Because step-down allocation hides this, most providers cannot say which service lines pay. TDABC makes the cross-subsidy explicit, turning a blended average into a defensible service-line P&L.

01The cross-subsidy nobody can name

A blended average hides who pays.

Under blended accounting a service line looks like a single number, and that number averages a profitable, high-volume procedure with a complex one that runs well below cost. The mix is invisible, so the cross-subsidy is real but unmanaged: a few lines fund the institution, many sit below cost, and the people setting budgets cannot tell which is which. Fragmentation across clinical, billing and cost systems is consistently the number-one barrier to seeing it.

SERVICE LINES, RANKED BY CUMULATIVE MARGIN

Illustrative. The whale curve applies to service lines as much as to products: a few lines build margin well past 100 percent of the total, then a long tail of below-cost lines drags it back.

02How to build the line P&L

Roll up the cases, then load the line.

Aggregate the TDABC procedure costs from the case level to the service line, then load the cost-to-serve of the line itself: theatre access, imaging, ward intensity, readmissions. A line that looks profitable on charges can sit below cost once its real consumption is loaded. In one documented case, a European hospital rebuilt its management view on a balanced scorecard after a merger, precisely to see performance by line rather than by legacy department.

01

Roll up procedure costs

Sum case-level TDABC costs into each service line, measured the way reimbursement is paid.

02

Load the line's cost-to-serve

Theatre access, imaging, ward intensity, readmissions: the shared resources the line actually consumes.

03

Rank against funding

Lines sort by true margin against their tariffs and block contracts, exposing the cross-subsidy.

04

Fund, price or redesign

Fund the cross-subsidy deliberately, price it with payers, and remove cost that is waste rather than care.

The clinical answer is rarely "stop doing it." It is to fund the cross-subsidy on purpose, price it correctly, and strip the waste, not the care.

Frequently asked questions

How many hospital services lose money?
In a typical hospital, roughly 30 to 40 percent of services are delivered below cost and are cross-subsidised by a smaller number of high-margin procedures. Procedure-level margins range from minus 40 percent to plus 60 percent within the same hospital, and step-down allocation hides this, so most providers cannot say which service lines pay.
Should a hospital stop loss-making service lines?
Not automatically. These are patients, not products. The point of service-line costing is to make the cross-subsidy a conscious, funded decision, to price it correctly with payers, and to strip out cost that is waste rather than care, not to ration.
How do you build a service-line P&L?
Roll up TDABC procedure costs to the service line, then load the cost-to-serve of each line, theatre access, imaging, ward intensity and readmissions. A line that looks profitable on charges can sit below cost once its real consumption is loaded.
