Why is Cost Accounting Important? - correct answer-Because reimbursement is
predetermined, management must focus primarily on finding way to manage
costs, so cost accounting is critical. Cost information is useful to a variety of key
decision-makers in a healthcare organization.
Incremental or Marginal Cost - correct answer-This is when costing decisions are
being made with the understanding that there is a difference in cost at two
different activity or volume levels.
Contribution Margin - correct answer-This is the difference between marginal
revenue and marginal cost. The contribution margin equals the revenue received
for one unit of service less the marginal expenses incurred for one unit of service.
The contribution margin is the amount of revenues remaining after meeting
marginal costs; this remaining margin goes toward supporting fixed costs.
Whatever is left goes to profit.
Break-Even Point (BEP) - correct answer-Break-even point is the level of sales
volume of a certain product (or service) producing the exact amount of
contribution margin needed to cover fixed costs.
Break-Even Equation - correct answer-BE= Fixed Cost/ Contribution margin per
unit
,Break-Even Point Calculation Example - correct answer-Revenue: $100,000.
Volume: 10,000. Revenue per Unit: $10.
Less: Variable Cost: $50,000. Volume: 10,000. Variable Cost per Unit: $5.
Contribution Margin: $50,000. Volume: 10,000. Contribution Margin per Unit: $5.
Less: Fixed Cost: $40,000. Volume: 10,000. Fixed Cost per Unit: $4.
Net Profit: $10,000. Volume: 10,000. Net Profit per Unit: $1.
Break-Even Point Calculation per Volumes of Unit Example - correct answer-
Revenue: $100,000. Volume: 10,000. Revenue per Unit: $10.
Less: Variable Cost: $50,000. Volume: 10,000. Variable Cost per Unit: $5.
Contribution Margin: $50,000. Volume: 10,000. Contribution Margin per Unit: $5.
Less: Fixed Cost: $40,000. Volume: 10,000. Fixed Cost per Unit: $4.
Net Profit: $10,000. Volume: 10,000. Net Profit per Unit: $1.
BEP = $40,000 (total fixed costs) / $5 (contribution margin per unit)
BEP = 8,000 units.
Full Absorption Costing - correct answer-Full absorption costing attempts to
allocate all overhead costs to all activities supported by those costs. Overhead, or
indirect costs, are allocated down to the revenue-producing activities based on an
objective methodology.
Differential Costing - correct answer-Differential costing ignores the overhead
costs and only looks at incremental costs that are directly related to the product.
Decision-Making Example - correct answer-The decision to use full absorption
costing or differential cost is made based on how the information will be used.
For example, when management is assessing the profitability of all hospital
,programs relative to one another, then it may be appropriate to consider
departmental costs on a full absorption basis. This may be an effective way to
identify marginally performing departments for further action.
If, however, the analysis was conducted to price a contract that would bring
incremental volume, but would require no additional investment of equipment or
indirect labor, then it would be appropriate to consider only marginal direct
(differential) costs.
Direct Costs - correct answer-These may be fixed or variable, but they are clearly
and directly associated with the activity that is being costed. Direct costs include
direct salaries and supplies.
Indirect Costs - correct answer-These may be fixed or variable, but they are NOT
clearly nor directly associated with the activity being costed. Overhead is a
common term for indirect costs. These costs are assigned to a service using some
acceptable allocation method. An example would include administration provided
in a hospital setting.
Activity-Based Costing (ABC) - correct answer-A method of determining product
costs using cost drivers or activity measures that cause indirect costs to be
incurred. Ideal cost drivers are activities that pertain to each procedure in varying
amounts. ABC provides an overview of developing and analyzing cost information
by service line.
Activity-based costing is generally considered a more accurate costing method
than the proportionate allocation method. It is, however, often more expensive
to determine due to the necessary data collection. ABC provides the foundation
for clinical improvement efforts by a more accurate identification of payment risk.
, Activity-Based Costing (ABC) Example - correct answer-An example of ABC would
be using the level of a specific equipment use to determine the allocation of
depreciation and repair expense.
Activity-Based and Service-Line Costing (ABC) Example - correct answer-For
example, the resources consumed by a cardiac patient in an imaging department
are considerably more than the resources consumed by a patient with
pneumonia.
Activity-Based and Service-Line Costing - correct answer-Healthcare
organizations have developed service lines based on major diagnostic categories
(for example, diseases of the digestive system or obstetric procedures).
The advantage of analyzing results by diagnostic category is that it develops an
estimate of total resources consumed, including resources consumed in shared
departments.
Service-Line Costing (Profitability Analysis) - correct answer-There are several
objectives of analyzing profitability according to service lines.
Shift financial analysis toward the major lines.
Determine the advantages or disadvantages of being in that product line.
Emphasize or de-emphasize certain services.
Determine data for use in benchmarking among clinical specialties.
Service-line costing can also be useful in assessing the profitability of a proposed
managed care contract and in developing carve-out rates for specific types of
cases (for example, open-heart surgeries and bone marrow transplants).
Responsibility Accounting - correct answer-The assignment or allocation of cost
to the individual manager who is primarily responsible for making decisions about
those costs. Once the primary responsibility for incurring a specific cost has been
