Richard -- what I find interesting about cases like these are that they are usually flagged b/c the doc is stepping far out of bounds of statistical norms, so their behavior is easy to pick up and scrutinize.
How much fraud/abuse/improper billing do you think is being hidden by docs sticking inside the fat part of the bell curve, and thus harder to see? Is the overall impact greater than those outliers?
I believe (my personal opinion only!) that in today's statistical analytical program, there is rarely a situation that any particular provider's billing patterns are not known. Of course, it is also well known that the time it takes to prosecute someone for low transaction rate/amount is the same for someone who has a high transaction rate/amount in their claims. I think you can see who will be evaluated further for deeper analysis.
I also believe that an analysis can occur over an aggregate of providers in a partiuclar state or even within the provider's self for variations in billing patterns.
A good example is the prevalence of keratoconus. If the prevalence in the general popuilation of keratoconus is "1 in 2000" (Rabinowitz,1998), then it is variance from the norm that a provider is billing for keratoconus contact lens care (non-elective, or medically necessary) at a prevalence rate that exceeds 1 in 1000. Let's' also suppose that the aggregate optometrists is submitting claims for testing AMD at an estimated prevalence rate of 75% where the commonly accepted prevalence rate is 15% (Friedman et al., 2004).
if the provder has the appropriate documentation to support such care, then the provider could survive whatever audit that may occur. In summary, any particular provider cannot "hide" amongst the aggregate.
