Poehling Medical Center has a single operating room that is used by local physicians to perform surgical procedures. The cost of using the operating room is accumulated by each patient procedure and includes the direct materials costs (drugs and medical devices), physician surgical time, and operating room overhead. On January 1 of the current year, the annual operating room overhead is estimated to be: Disposable supplies $375,800 Depreciation expense 67,800 Utilities 39,400 Nurse salaries 564,300 Technician wages 184,700 Total operating room overhead $1,232,000 The overhead costs will be assigned to procedures based on the number of surgical room hours. Poehling Medical Center expects to use the operating room an average of eight hours per day, seven days per week. In addition, the operating room will be shut down two weeks per year for general repairs. a. Calculate the estimated number of operating room hours for the year. hours b.

The actual overhead costs incurred for January were $80,000. Determine the overapplied operating overhead or underapplied operating overhead for the period. Enter your answer as a positive number. $

Answer 1

Solution

Poehling Medical Center

1. Estimated number of operating room hours for the year:

Estimated number of annual surgical hours of the operating room = 8 hours x 7 days x 50 weeks =2,800 hours

(The operating room will be shut down for two weeks for general repairs, so number of estimated weeks in the year = total number of weeks in a year minus two weeks for general repairs

So, 52-2 = 50 weeks)                                                                                                                              

2. Determination of predetermined operating room overhead rate for the year:

Calculation of predetermined rate = estimated annual overhead/estimated number of hours

Total estimated operating room overhead for the year =$1,232,000

Thus, the predetermined operating room overhead rate =$1,232,000/2,800 =$440 per surgical hour

3. Calculation of the operating room overhead charged to the 7-hour procedure conducted by Bill Harris:

= predetermined overhead rate x actual number of hours used

$440 x 7 hours =$3,080

4. Determination of over or under applied overhead rate in the month of January:

Number of hours the operating room was used in January is 186

Actual overhead cost =$80,000

Applied overhead cost for 186 hours =186 x $440 = $81,840

Overapplied operating overhead = applied overhead – actual overhead = 81,840 – 80,000 = $1,840

Thus, overapplied operating overhead cost for the month of January =$1,840
