Managerial/Cost Accounting | University of Texas at Austin
Difficulty: Intermediate | Prerequisites: Introductory cost accounting concepts (cost pools, cost drivers, overhead allocation). Familiarity with healthcare reimbursement basics is helpful but not required.
This case sits at the intersection of healthcare economics and managerial accounting. Boston Children's Hospital (BCH) is a top-ranked paediatric hospital that found itself losing contracts and volume because its prices were significantly higher than competitors. The case forces you to evaluate two costing systems, Ratio-of-Cost-to-Charges (RCC) and Time-Driven Activity-Based Costing (TDABC), and decide which gives managers the information they need to price services, cut waste and survive in a market shifting from fee-for-service to fixed-payment models. If your course covers cost allocation, activity-based costing or healthcare management accounting, this is the applied version of those concepts.
BCH is a world-class children's hospital whose high costs made it uncompetitive against rivals like Tufts Floating Hospital. The traditional RCC costing method treats all procedures as equally costly per charge dollar, hiding the true resource consumption of complex versus simple cases. TDABC offers a more accurate alternative by tracking the actual time each resource spends on each activity across a full care cycle.
Ratio-of-Cost-to-Charges (RCC)
The standard hospital costing method that assumes costs are proportional to charges. It applies a single ratio (total costs / total charges) to every department's charges to estimate the cost of any procedure. In simple terms, it spreads overhead evenly across all services based on what they bill, regardless of how many resources each service actually uses.
Time-Driven Activity-Based Costing (TDABC)
A costing method that maps every administrative and clinical step in a care cycle, then assigns costs based on two inputs: the cost per minute of each resource and the number of minutes each resource spends on each activity. Think of it as a stopwatch-and-payroll approach to costing: you time each step, then multiply by the cost rate of whoever is doing it.
Cost driver
The factor that causes a cost to increase or decrease. In TDABC, time is the primary cost driver. In simple terms, a cost driver answers the question: "What makes this more or less expensive?"
Alternative Quality Contract (AQC)
A contract model used by Blue Cross Blue Shield that sets fixed (global) payments for a provider, with bonuses tied to savings and quality targets. It replaces traditional fee-for-service billing with a budget-style arrangement.
Global payment / risk-adjusted global payment
A fixed lump-sum payment to a provider for all care delivered to a patient population over a period, adjusted for the health risk profile of that population. In simple terms, the insurer pays the hospital a set amount per patient, and the hospital must manage costs within that budget.
Fee-for-service
The traditional reimbursement model in which providers bill separately for each service, test or procedure performed. Each line item generates revenue, so there is little incentive to reduce the number of services delivered.
Care cycle
The full sequence of activities a patient goes through for a medical condition, from initial consultation through treatment to follow-up. TDABC maps costs across this entire cycle rather than pricing individual procedures in isolation.
Capacity cost rate
The cost per unit of time (usually per minute) for a given resource, calculated by dividing the total annual cost of that resource by the number of minutes available for clinical work per year. This is one of the two core inputs for TDABC.
Value framework (outcomes / cost frontier)
A conceptual model that plots healthcare providers on two axes: patient outcomes (vertical) and cost (horizontal). The efficient frontier is the curve where maximum outcomes are achieved for a given cost. Providers above or on the curve deliver good value; those below it do not.
Largest independent paediatric hospital in the US, ranked No. 1 by U.S. News & World Report in 2011
Over 500,000 patients and 26,000 surgical procedures annually (2011 figures)
One of the largest paediatric hospital-based research centres, with 1,100+ scientists
Serves as the "last resort" for children with rare diseases (e.g. Bubble Boy Syndrome)
Physicians employed by 15 independent foundations, not by the hospital directly
Foundations rent clinical space from BCH
Patients are billed separately for physician expenses and hospital expenses
This dual-billing structure complicates cost accounting
2006: Massachusetts enacted universal coverage through mandates and subsidies
2008: State formed the Commission on the Health Care Payment to address rising costs
Commission recommended a shift to risk-adjusted global payments for all providers
This pushed hospitals away from fee-for-service and toward fixed-budget reimbursement
BCH reported the highest costs of any paediatric hospital in Boston
Tufts' Floating Hospital for Children charged prices roughly 50% lower than BCH
Tufts saw growing volume and revenue; BCH saw declining profits and exclusion from insurance networks
BCH's high costs stem partly from its large research operation, not purely from clinical care
Signed the Alternative Quality Contract (AQC) with Blue Cross Blue Shield
AQC structure: fixed payments plus bonuses for hitting savings and quality targets
No rate increases in 2012, with sub-inflation increases thereafter
The contract forced BCH to understand its true cost structure, because overspending now comes out of the hospital's pocket rather than being passed to the insurer
Collect all charges from each revenue-producing department
Aggregate traceable expenses for each department
Add allocated shared costs (overhead) to each department
Calculate the RCC rate: Total Department Costs / Total Department Charges
Multiply any procedure's charge by the RCC rate to estimate its cost
Costs are proportional to charges (a procedure that charges twice as much is assumed to cost twice as much)
Charges reflect underlying resource consumption
All procedures within a department consume resources at the same rate per charge dollar
The RCC table from the case makes the problem visible. Three very different procedures in BCH's plastic and oral surgery department, plagiocephaly, neoplasm skin excision and craniosynotosis, all show the same charge ($350), the same average reimbursement ($224), the same RCC cost ($210) and the same RCC profit ($14).
In reality, these procedures are vastly different in complexity. A neoplasm skin excision is a relatively straightforward removal. Craniosynotosis surgery involves reshaping the bones of an infant's skull and requires a multi-hour operation with a large surgical team. RCC treats them as identical because their charges happen to be the same. This is the core flaw: RCC cannot distinguish between a simple and a complex procedure if both carry the same charge.
Simple to implement and maintain
Data inputs (charges and total costs) are readily available from existing billing and financial systems
No need for detailed process mapping or time studies
Historically adequate when fee-for-service reimbursement covered costs regardless of accuracy
Under global payments, this simplicity becomes a liability because the hospital bears the risk of mispriced services
\text{RCC Rate} = \frac{\text{Total Department Costs}}{\text{Total Department Charges}}\text{Estimated Procedure Cost} = \text{Procedure Charge} \times \text{RCC Rate}In the BCH case, the department-level RCC rate is 210/350 = 0.60, so every dollar of charge is assumed to carry 60 cents of cost. A $350 procedure therefore has an estimated cost of $210 regardless of actual resource use.
The RCC versus TDABC debate is not unique to hospitals. Any service organisation with high overhead, diverse products and indirect cost allocation faces the same problem. Law firms, consulting firms and universities all use variants of these methods. The shift from fee-for-service to global payments in healthcare mirrors the broader trend in professional services toward fixed-fee and value-based pricing, where knowing your true cost per engagement is the difference between profit and loss.
Students often assume RCC is "wrong" and TDABC is "right." RCC is not wrong in principle; it is a simplification that works tolerably when procedures within a department are similar. It breaks down when procedures vary widely in complexity, which is exactly the situation at BCH.
Students sometimes confuse charges with costs. A charge is the list price the hospital sets. A cost is the actual resource consumption. RCC assumes these move together, but hospitals frequently set charges based on market positioning, historical convention or regulatory rules rather than resource use.
Students often overlook why BCH's costs are high in the first place. The research operation is a major driver. The case is asking about costing methods, but the underlying strategic question is whether BCH can separate its research costs from its clinical pricing so it can compete on clinical work alone.
Students sometimes think the AQC contract is simply a cost-cutting measure. It is a risk-transfer mechanism: under fee-for-service, the insurer bears the cost risk; under global payments, the hospital does. That shift is what makes accurate costing suddenly urgent.
⚠️ Be prepared to explain why RCC produces identical cost and profit figures for different procedures. The answer is the proportionality assumption: same charge = same estimated cost.
⚠️ Know the difference between fee-for-service and global payment models, and explain why the shift between them makes costing accuracy matter more.
⚠️ Be ready to discuss why BCH's physician foundation structure complicates cost measurement. Dual billing (physician costs + hospital costs) means some costs are outside the hospital's direct accounting.
⚠️ Expect a question on when RCC is "good enough" versus when a hospital needs TDABC. The answer turns on product diversity and cost structure complexity.
True or False: Under RCC, a simple skin excision and a complex craniosynotosis repair that carry the same charge will show the same estimated cost. (True)
Fill in the blank: The RCC rate is calculated by dividing total department ______ by total department ______. (costs; charges)
True or False: Under the AQC with Blue Cross Blue Shield, BCH receives additional revenue for every procedure it performs. (False, the AQC uses fixed payments with bonuses for savings and quality, not per-procedure billing)
Fill in the blank: BCH's high costs relative to competitors stem partly from its large ______ operation. (research)
True or False: RCC requires detailed process mapping and time studies to implement. (False, that describes TDABC)
Q: What is the fundamental assumption of the RCC costing method, and why does it fail in BCH's plastic and oral surgery department?
A: RCC assumes that costs are proportional to charges. It fails at BCH because procedures of vastly different complexity (e.g. a skin excision versus a craniosynotosis repair) can carry the same charge, making their estimated costs identical even though their actual resource consumption differs enormously.
Q: Why did BCH sign the Alternative Quality Contract with Blue Cross Blue Shield, and what does this imply for the hospital's costing needs?
A: BCH signed the AQC to address its declining competitiveness and exclusion from insurer networks. The AQC provides fixed payments with bonuses for savings and quality. Under this model, BCH bears the financial risk of cost overruns, so accurate cost information becomes essential for strategic decisions about which services to offer and how to price them.
Q: Explain why the shift from fee-for-service to global payments increases the urgency of accurate cost measurement for a hospital.
A: Under fee-for-service, the insurer reimburses each service at or above cost, so the hospital can absorb inaccurate costing. Under global payments, the hospital receives a fixed budget per patient. If it underestimates the cost of certain procedures, it will lose money on those cases without knowing why. Accurate costing is the only way to identify which services are profitable and which are not.
Q: BCH's physicians are employed by independent foundations rather than by the hospital. How does this structure affect cost accounting?
A: Patients receive two separate bills: one for physician-related expenses (from the foundation) and one for hospital expenses. This means hospital-level cost accounting captures only part of the total cost of care. Any attempt to measure true per-procedure costs must account for both streams, which complicates data collection and allocation.
Q: Tufts' Floating Hospital charges prices 50% lower than BCH. Does this necessarily mean Tufts is more efficient? What other explanation is possible?
A: Not necessarily. BCH's higher prices may reflect the cost of its large research operation, which is bundled into its overall cost structure. BCH may be quite efficient in clinical care delivery but appear expensive because research costs are spread across all services. The case highlights that without accurate costing, BCH cannot isolate clinical costs from research costs to answer this question.
This material connects directly to activity-based costing (ABC) and the critique of traditional overhead allocation, which you will likely have covered earlier in the course. The RCC method is a real-world example of a single-rate, volume-based allocation system and its limitations.
The healthcare reform context connects to broader topics in strategic management accounting: how external market pressures (regulation, competition, payment reform) drive changes in internal cost systems.
The value framework (outcomes versus cost) also ties into operations management and the concept of the efficient frontier, where organisations compete by delivering more outcome per unit of cost.
