Defending your “Arbitrary and Capricious” Samples Bradley M. Casselman, M.S. Senior Statistician
As we become more and more adept at identifying Fraud, Waste, and Abuse, we are seeing estimated overpayments from statistical sampling rise Large $$ overpayments are leading to more and more aggressive defense from appellants ALJ hearings and court appearances are becoming more and more common… The ALJ, Court and other fun ways to spend an afternoon
Providers have the right to appeal decisions made by either the MAC (AC) or the PSC to a first level review, then on to fair hearings, and if necessary, on to an Administrative Law (ALJ) hearing. PSC’s usually become involved (if notified) at the ALJ level. The Appeals Process
This has become the “catchphrase” of recent challenges to Statistical Sampling for Overpayment Estimation (SSOE) Appellants have added due process challenges in addition to standard statistical challenges …arbitrary and capricious…
1: depending on individual discretion (as of a judge) and not fixed by law 2 a: not restrained or limited in the exercise of power : ruling by absolute authority b: marked by or resulting from the unrestrained and often tyrannical exercise of power 3 a: based on or determined by individual preference or convenience rather than by necessity or the intrinsic nature of something b: existing or coming about seemingly at random or by chance or as a capricious and unreasonable act of will
"name": "1: depending on individual discretion (as of a judge) and not fixed by law 2 a: not restrained or limited in the exercise of power : ruling by absolute authority b: marked by or resulting from the unrestrained and often tyrannical exercise of power 3 a: based on or determined by individual preference or convenience rather than by necessity or the intrinsic nature of something b: existing or coming about seemingly at random or by chance or as a capricious and unreasonable act of will
governed or characterized by caprice –1 a: a sudden, impulsive, and seemingly unmotivated notion or action b: a sudden usually unpredictable condition, change, or series of changes –2: a disposition to do things impulsively
The Guidelines The CMS Program Integrity Manual (PIM), Chapter 3, Section 10 outlines use of Statistical Sampling for Overpayment Estimation for MAC’s (AC’s) and PSC’s Additionally, there are criteria under HCFA Ruling 86-1 that apply to conducting an SSOE
Lines of Defense There are a few things that we can do as contractors to provide the best chance of prevailing at ALJ hearings: –Fully document your process –Conduct a full analysis of appellant statistical expertise –Retain a Ph.D., even if you have to subcontract for one –Make sure lines of communication are open with the ALJ office, the MAC/AC, and the QIC
Documentation Documentation is critical for a successful defense of SSOEs A list of necessary items can be found in the PIM, Chapter 22.214.171.124 This is an area of debate, however…
Documentation PIM 126.96.36.199.1 states: –A record shall be kept of the random numbers actually used in the sample and how they were selected. Sufficient documentation shall be kept so that the sampling frame can be re-created, should the methodology be challenged. Note that the PIM only states that documentation shall be kept so that the sampling frame can be re-created. It does not state that a contractor must “teach” the appellant the computer programming language so that they can re-create the sampling frame
Documentation Your documentation should include: –A concise definition of how the universe of claims was selected –A clear definition of the sampling unit –The random number seed –A listing of the sampling frame with the associated random numbers –Listing of software/programs used to accomplish the random sample –A summary of Universe and Sample statistics –Your credentials and contact information –Date that the sample was selected
Documentation Additional areas of documentation that should be kept, include, but are not limited to: –Documentation from the Investigations unit as to why the SSOE is being conducted in the first place –Documentation from Medical Review if there are workload considerations that may limit the amount of claims reviewed –A worksheet of review decisions from Medical Review along with the associated overpayment amount per sampling unit
Analyze the Appellant’s Documentation If the appellant challenges a SSOE, then there is usually an accompanying document explaining why you are wrong and they are right… This document should be analyzed thoroughly for any errors, stretched truths, and irrelevancies.
Analyze the Appellant’s Documentation Also, use prior case law to counteract arguments made by the appellant’s expert Some especially useful cases to look at are: –Pruchniewski v. Leavitt –Ratanasen v. State of California Department of Health Services –Department of Education v. United States Department of Education
Analyze the Appellant’s Documentation Pruchniewski v. Leavitt –This case is intriguing on a few issues The ALJ, then later the U.S. District Court in FL upheld a sample of size 30 The retained expert for the appellant, Dr. Michael Intrilligator, is rebuffed in many of his standard arguments, such as: –The fact that there is no such thing as “Generally Accepted Statistical Standards” and this is a term invented by Dr. Intrilligator –The prior sampling appendix numbers are non-binding –OAS and OIG sampling guidelines are not binding to CMS –The fact that the use of the lower limit of a 90% one-sided CI is reasonable and is a valid remedy for larger COV’s –A sample of size 30 was deemed statistically acceptable
Analyze the Appellant’s Documentation Ratanasen v. State of California Department of Health Services –The United States Court of Appeals, Ninth Circuit found that “the cases addressing sampling cited above make no mention of a statistical ‘floor’ which auditors must exceed in order to guarantee providers due process” when addressing a challenge that a sample was too small.
Analyze the Appellant’s Documentation Michigan Department of Education v. United States Department of Education –The United States Court of Appeals, Sixth Circuit found that: “There is no case law that states how large a percentage of an entire universe must be sampled.”
Retaining a Ph.D. One useful tool in SSOE defense is retaining a Ph.D. Statistician Regardless of whether your argument is correct, some will judge based on a M.S. argument vs. a Ph.D. It is therefore very helpful to have a Ph.D. on your side at a hearing
Lines of Communication This may be the most important aspect of your SSOE defense ALJs and QICs often communicate results to the AC/MAC if a PSC is involved. It is imperative to maintain open lines of communication to ensure that you are notified of any hearings. Your chance of success is much greater when you are allowed to present your side!
