Brooklyn ambulance service overbilled feds by millions: audit
A Brooklyn ambulance service took taxpayers for a ride, overbilling the federal government by more than $19 million for transporting Medicare patients, according to an audit released Friday.
The inspector general of the US Department of Health and Human Services examined 100 bills from Midwood Ambulance Service during 2014-2015 for “non-emergency” transport services and rejected 89 as non-compliant.
“For 82 claims, Midwood billed for services for beneficiaries whose conditions did not meet Medicare medical necessity requirements (requiring ambulance transport for doctor’s visits),” the audit said.
For 49 claims, Midwood failed to obtain doctors’ written certification in a timely or proper manner to justify ambulance transport of patients.
Based on the sample audit, the IG disallowed most of the 114,138 claims Midwood filed — or $19.2 million of the $23.5 million in payments.
Midwood challenged the findings based on statistical sampling.
“Midwood cannot simply accept the OIGs findings and make such an exorbitant refund without the ability to further investigate individual claims … Midwood is not convinced a $19 million overpayment refund is warranted,” Midwood president Al Rapisarda said in a written response to the IG.
Rapisarda also said Midwood was sold in September and is basically broke.
“The sale was necessary because Midwood was losing money and had extensive debts. The business was sold at a loss, with barely enough to cover existing debts,” he told the feds.
Midwood Ambulance & Oxygen Service, Inc., Billed for Nonemergency Ambulance Transport Services That Did Not Comply With Medicare Requirements
Medicare covers nonemergency ambulance transportation when furnished to a beneficiary whose medical condition is such that other means of transportation could endanger the beneficiary's health. Medicare paid Midwood Ambulance & Oxygen Service, Inc. (Midwood), an ambulance company in Brooklyn, New York, $23.5 million for 114,000 claims with payments of $100 or more for nonemergency ambulance transport services provided during 2014 and 2015 (audit period).
Midwood did not comply with Medicare requirements for billing nonemergency ambulance transport services for 89 of the 100 claims we reviewed. Specifically, Midwood incorrectly billed Medicare for beneficiaries whose conditions did not meet medical necessity requirements and billed for services that did not meet documentation requirements. These errors occurred because Midwood did not have adequate controls to prevent the incorrect billing of nonemergency ambulance transport claims. On the basis of our sample results, we estimated that Midwood received overpayments of at least $19.2 million for the audit period. This amount includes claims with payment dates outside of the Medicare 4-year claim-reopening period.
We made a series of detailed recommendations to Midwood. Among them, we recommended that Midwood (1) refund to the Medicare program the portion of the estimated $19.2 million overpayment for claims incorrectly billed that are within the Medicare reopening period; (2) for the remaining portion of the estimated $19.2 million in overpayments for claims that are outside of the Medicare reopening period, exercise reasonable diligence to identify and return additional overpayments; (3) identify and return any additional similar improper payments made after our audit period; and (4) strengthen its procedures for billing nonemergency ambulance transport services.
Midwood disagreed with our first two recommendations, did not indicate concurrence or nonconcurrence with our third recommendation, and partially agreed with our fourth recommendation. Midwood stated that it could not agree with our findings without performing a detailed review of our determinations. Further, Midwood stated that it did not agree with our use of statistical sampling. Midwood also stated that the length of the Medicare reopening period cited in our recommendations was unclear. After reviewing Midwood's comments, we maintain that our recommendations are valid. Our findings were based on determinations made by a qualified independent medical review contractor. Also, Federal courts have consistently upheld statistical sampling and extrapolation as a valid means to determine overpayment amounts in Medicare and Medicaid.
