TDABC in Healthcare: Measuring the True Cost of Patient Care

Healthcare is one of the sectors where Time-Driven Activity-Based Costing has had the most transformative impact. With rising costs and increasing pressure to deliver value-based care, healthcare organizations need accurate cost information more than ever.

The Challenge of Healthcare Costing

Traditional costing in healthcare typically uses ratio of costs to charges (RCC) or relative value units (RVUs) to allocate costs. These methods treat all patients within a diagnosis group as if they consume the same resources, which is far from reality. A routine appendectomy and a complex one with complications consume vastly different resources, yet traditional methods may assign them similar costs.

How TDABC Transforms Healthcare Costing

TDABC maps the entire care delivery value chain for a medical condition. It identifies every resource involved in treating a patient, from the initial consultation through treatment, recovery, and follow-up. Time equations capture the actual time each resource spends on each step of the care cycle.

This approach reveals several critical insights. It shows the true cost of treating specific conditions across different patient profiles. It identifies process inefficiencies where clinical staff spend time on non-value-adding activities. It highlights opportunities for care pathway redesign. And it provides the foundation for meaningful bundled payment negotiations.

Real-World Results

Healthcare organizations that have implemented TDABC typically discover significant variation in the cost of treating similar conditions. This variation is not random; it correlates with specific patient characteristics, provider practices, and process differences that can be measured and managed.

At Cost and Profitability Consulting, we work with healthcare institutions to implement TDABC models that provide actionable cost transparency, enabling better clinical and financial decisions.
