Sheridan Orthopedics specializes in hip, knee, and shoulder replacement surgery. In addition to the actual surgery, the company provides its patients with preoperative and postoperative inpatient care in a fully equipped hospital. Sheridan pays its surgeons a fixed fee for each surgical procedure they perform. The company provides doctors and patients a variety of support services during treatment and allocates the cost of these activities through the company's costing system, which uses a single overhead rate. Currently, the company uses an allocation rate of 48% of the surgical fee charged to the patient. Managers have expressed concern that the current system is producing inaccurate costs and profitability for the joint replacement procedures. As a result, Bree Sheridan, the company's controller, initiated a study to explore the potential for implementing an activity-based costing system. She has collected the following data on each of the procedures. Fee charged to patient Number of procedures per year Average time per procedure Number of procedures per operating room session Inpatient days per procedure Surgeon's fee per procedure Medical supplies per procedure Hip Knee Shoulder $11,000 $15,000 $7,000 1,000 500 600 4.0 hours 1.0 hours 2.0 hours 2 1 4 4 3 2 $1,200 $1,800 $1,500 $400 $200 $300
