Medicare: What determines payments for physicians’ services?
The Physician Fee Schedule, which is based on the Resource-Based Relative-Value Scale.
Medicare: Examples of “unbundling” of laboratory services.
Billing separately for tests in a panel.
Billing separately for the cervix and corpus of a uterus.
Medicare: Direct-billing law as it applies to laboratories.
Medicare must be billed directly by the laboratory that provides the service.
Medicare: Stark law:
A. Synonym.
B. Intent.
A. Physician-self-referral law.
B. To prevent the use of “shell laboratories” that only refer testing to real laboratories but bill Medicare directly.
Medicare: Components of the anti-kickback law.
A laboratory may not use items of value to induce clinicians to use their services.
When trying to attract non-Medicare patients, the laboratory may not charge less than the cost of the testing.
Fixed vs. variable costs: Definitions.
Fixed costs are unaffected by the total number of tests performed. However, the fixed cost per test decreases as more tests are performed.
Variable costs are affected by the total number of tests performed. However, the variable cost per test does not change.
Fixed costs: Examples.
Purchase of instruments, utilities, rent, wages.
Direct vs. indirect costs: Definitions.
Direct costs are incurred directly from the performance of tests; indirect costs are not.
Direct vs. indirect costs: Examples.
Direct costs: Purchase of instruments, reagents.
Indirect costs: Rent, utilities, custodial services, depreciation.
Over which costs does a laboratory director have the greatest control?
Over direct costs and variable costs.
Unit cost:
A. Definition.
B. Derivation.
A. The total cost per test.
B. The sum of the variable costs and fixed costs per test.
Break-even point:
A. Definition.
B. Relevance.
A. The number of tests to be performed in order for costs to balance revenue, i.e. where net income equals zero.
B. Can help determine whether to offer a test or send it out.
Break-even point: Formula.
N = FC ÷ (R − VC).
N is the number of tests performed.

VC is the variable cost (per test).
