A Tennessee ambulance company and the U.S. Department of Health and Human Services (DHHS) announced a settlement in a case over a post payment audit for more than two million dollars in May 2012. Back in March of 2010, the Nashville ambulance company sued the DHHS after being sent a $2.65 million overpayment demand, according to the Nashville Business Journal.

Mammoth Fine Came from Error Rate Extrapolation Formula.

According to the lawsuit, the ambulance company claimed that the fine was based on incorrect accounting by a Medicare Administrative Contractor (MAC) for the DHHS. The contractor reviewed “a small sample of claims and determined that many did not meet Medicare coverage criteria.”

The actual overpayment on those claims was $10,764, which was determined to be an error rate of fifty-one percent (51%). The error rate was then used to extrapolate and obtain the $2.65 million figure which was demanded from the ambulance company.

Ambulance Company Cried Foul.

Upon administrative appeal, the ambulance company said most of its claims were determined to be appropriate, yet the error rate was never recalculated and the company was still stuck with a large bill.

Disputes of payments included bills for transporting dialysis patients by ambulance. The DHHS said those trips were not valid because they were not emergencies. The ambulance company refuted this contending that the trips did not have to be emergencies because they were ordered by a doctor.

Use of Statistical Sampling and Extrapolation Formulas to Multiply Repayment Amounts.

In both state Medicaid audits and in Medicare audits, we have experienced increased reliance by the auditing agency on use of mathematical extrapolation formulas to estimate the amount that should be repaid. The formula used usually takes the overpayment that has actually been found and, based on several factors, multiplies it out to many times the actual overpayment amount, as is the example in this case. We have seen ratios of as high as 1 to 150 (or 150 times the actual disallowed claims amount) calculated.

Things you should know about this are as follows:

1.  Neither the Medicare program nor the state Medicaid programs should use an extrapolation formula, unless:
  a. There is a “high” error rate in the claims that have been submitted; or
  b. There have been prior educational efforts or prior audits of the provider, and the provider
  has failed to correct the problems in claims submission previously found.

2.  The states each have different guidelines, rules or regulations on when they will apply the statistical formula. Some do not use it at all. Some use a higher percentage error rate to prompt use of the formula and some lower. For example, North Carolina uses one of the lowest percentage error rates we have encountered; an error rate of more than five percent (5%) will prompt its Medicaid agency to apply the statistical extrapolation to the recovery amount.

Two Parties Come to a Compromise.

On May 25, 2012, the United State District Court announced the ambulance company and the DHHS had settled and compromised. The lawsuit was dismissed against the DHHS without prejudice for a period of ninety (90) days.
