I have never heard of anyone billing for a negative control and would
highly recommend against doing so. As mentioned, it is a cost of doing
business--which is why when CAP clarified that polymer detection systems

Controls are never billable, a control test does not produce a usable result
based on the patient's specimen. The results of control tests - positive or
negative only tell you that your reagents, stains, antibodies etc. are
performing as expected.

We try to run 1/2 of the required cases with known negative cases and the other
1/2 with known positive cases. In addition, all cases are run with a negative
