Activity-Based Costing in Healthcare: How It Actually Works

This is a lesson from from our CPE course on Cost Accounting For Healthcare.

Ever wondered why some hospital departments, like orthopedics or cardiology, seem to generate higher profits than others? The answer often lies in how costs are tracked and allocated. Activity-Based Costing (ABC) is a powerful method that brings clarity to healthcare financials by tying costs to specific activities. In our latest free lesson video, we break down ABC through a real-world hospital case study. Read on to discover how ABC works in healthcare and why it’s a game-changer for financial management.

What Is Activity-Based Costing?

Unlike traditional costing methods that evenly distribute overhead costs across all hospital services, ABC assigns costs based on the actual activities involved in patient care. This approach reveals the true cost of each service line, helping hospitals make smarter decisions about pricing, resource allocation, and profitability. Our free lesson video walks through a hospital scenario where ABC uncovers why orthopedic surgeries and cardiology procedures outperform other departments.

Benefits of Activity-Based Costing

ABC isn’t just a buzzword—it delivers real advantages for healthcare organizations:

• Pinpoint Accuracy: Costs are tied to specific activities, revealing the true financial performance of each department.
• Smarter Decisions: Managers can identify high-cost activities, optimize resources, and set competitive prices.
• Transparency: ABC clarifies cost drivers, making it easier to justify budgets and strategic plans to stakeholders.
• Adaptability: The method adjusts to variations in patient care, ensuring precise cost estimates for complex cases.

These benefits make ABC a must-have tool for hospitals aiming to boost efficiency and profitability.

How Activity-Based Costing Works: A Hospital Case Study

Let’s dive into how ABC is applied in a healthcare setting, using a hospital case study from our course. The hospital’s leadership noticed that orthopedic and cardiology services were more profitable but didn’t know why. By implementing ABC, the accounting team followed these four steps:

1. Identify Key Activities

The first step is to pinpoint the activities driving costs. The hospital categorized activities into three cost centers:

• Pre-procedure: Patient registration and pre-op consultations.
• In-procedure: Operating room usage, surgical staff time, and anesthesia.
• Post-procedure: Follow-up visits and physical therapy.

Each activity is labeled as a direct or indirect cost, setting the stage for precise allocation to service lines.

2. Calculate Resource Costs

Next, the hospital determines the cost of each activity and its cost driver. For example:

• Operating room: $15 million annually, driven by 50,000 hours of usage.
• Anesthesia: $5 million, based on procedures performed.
• Physical therapy: $1 million, tied to therapy sessions.

These figures help link costs to the specific activities that generate them.

3. Assign Costs to Departments

Activities are then mapped to relevant departments. In this case, all three activities (operating room, anesthesia, and physical therapy) apply to both orthopedic surgeries and cardiology procedures. Depending on the hospital, some activities might only relate to specific departments, making ABC highly customizable.

4. Determine Cost Per Patient

Finally, costs are calculated per patient by dividing total costs by usage. For instance:

• Operating room: $15 million ÷ 50,000 hours = $300 per hour.
• For an open-heart surgery patient (1 hour in the OR, standard anesthesia, one physical therapy session), the cost is $850.
• If the patient needs five therapy sessions instead, ABC quickly adjusts to provide an updated cost.

This level of detail empowers hospitals to understand and manage costs with precision.

Why ABC Matters for Healthcare

ABC provides insights that traditional costing can’t match. By revealing the true cost of each patient interaction, hospitals can optimize high-performing departments, address inefficiencies, and plan strategically. Our case study shows how ABC helped a hospital understand why orthopedics and cardiology were thriving, paving the way for data-driven decisions.
