Appeal from United States District Court for the Southern District of Iowa - Central ____________ Submitted: December 13, 2023 Filed: July 5, 2024 ____________

Before SMITH,1 Chief Judge, GRUENDER and GRASZ, Circuit Judges. ____________

GRUENDER, Circuit Judge.

The False Claims Act (“FCA”) and the Iowa False Claims Act (“IFCA”) authorize private citizens, known as qui tam relators, to recover from those who make false or fraudulent claims for payment to the United States and the State of Iowa respectively. Relator, Stephen Grant, a sleep medicine practitioner, brought this qui tam action under the FCA and the IFCA against Steven Zorn, Iowa Sleep Disorders Center (“Iowa Sleep”), and Iowa CPAP. After a bench trial, the district court found that the defendants had submitted 1,050 false claims to the United States and the State of Iowa. The district court subsequently imposed a total award of $7,598,991.50. For the reasons set forth below, we affirm in part, vacate in part, and remand for further proceedings consistent with this opinion.

I.

Zorn operated and held substantial ownership interests in Iowa Sleep, a medical practice specializing in sleep medicine, and Iowa CPAP, a medical equipment company. Due to financial difficulties at Iowa Sleep, Iowa CPAP provided loans to Iowa Sleep. Iowa Sleep referred patients to Iowa CPAP for free consultations.

Iowa Sleep accepted state and federal funds for its services through government reimbursement programs like Medicare, Medicaid, and Tricare. The amount that can be billed for services rendered through government healthcare

-2- programs depends on a variety of factors, including the time spent with the patient and the complexity of the visit. The government determines the appropriate amount to be reimbursed based on the “code” billed by the provider. In sleep medicine, claims for initial patient visits are coded from 99201 to 99205, and claims for established patient visits are coded from 99211 to 99215. The last number of a code represents the complexity of the visit. Codes ending in the number “5” (e.g., “99205”) are considered the most complex and are reimbursed by the government at a higher rate than any other code.

The Centers for Medicare & Medicaid Services (“CMS”) oversees claims submitted to the federal government for reimbursement. CMS contracts with third- party administrators like AdvanceMed to handle claims and review, investigate, and audit payments made on behalf of the federal government. CMS, through AdvanceMed, advises service providers on proper billing practices and may notify service providers of suspected discrepancies between submitted claims and actual services rendered.

In September 2016, AdvanceMed sent a letter to Zorn expressing concern that Zorn was overbilling the government for his services. The letter informed Zorn that, between June 2012 and June 2016, he had billed the majority of his established patient visits at codes 99214 and 99215 and all of his initial patient visits at code 99205. AdvanceMed stated that “[m]ore variety would be expected,” and it “would like to educate [Zorn’s] office” on proper billing practices.

In January 2018, following an audit of patient records from January 2017 to September 2017, AdvanceMed sent another letter to Zorn. This letter informed Zorn that AdvanceMed had “identified overpayments made to” him. The letter suggested that Zorn “[c]onsider and implement corrections to billing procedures that could prevent such errors in the future.”

Grant practiced sleep medicine at Iowa Sleep and held 10% ownership interests in both Iowa Sleep and Iowa CPAP. Grant obtained copies of the

-3- AdvanceMed letters through Iowa Sleep’s office manager. He became concerned that “if there were any forensic ramifications from [Zorn’s overbilling], it would fall squarely on [Grant], as well as the knowledge that Dr. Zorn was doing this and [Grant] was not doing anything about it.”

In March 2018, Grant filed this qui tam action on behalf of the United States and the State of Iowa (collectively, “the government”) against Zorn, Iowa Sleep, and Iowa CPAP, alleging the defendants had violated the FCA and the IFCA by knowingly overbilling the government for initial and established patient visits. See 31 U.S.C. § 3729(a)(1); Iowa Code § 685.2. He further alleged that the defendants had violated the FCA and the IFCA by knowingly soliciting and directing referrals from Iowa Sleep to Iowa CPAP in violation of the Anti-Kickback Statute and the Stark Law. See 42 U.S.C. §§ 1320a-7b(b)(2)(A), 1395nn(a)(1)(A). The government declined to intervene in the action. See 31 U.S.C. § 3730(b)(2); Iowa Code § 685.3(2)(b).

Zorn fired Grant from Iowa Sleep in September 2018. Grant subsequently amended his complaint to include a claim for retaliation under the FCA and the IFCA against Iowa Sleep. See 31 U.S.C. § 3730(h); Iowa Code § 685.3(6). He alleged that Zorn fired him for reporting potential FCA and IFCA violations to the government.

During discovery, Grant requested 1,167 medical files from the defendants. Believing Grant’s request to be too burdensome, the defendants asked Richard Braak, a certified public accountant, to randomly select thirty-one patient files from a list of Zorn’s patient files. Braak randomly chose thirty-one files, all of which pertained to initial patient visits, and the defendants provided these thirty-one files to Grant.

Instead of asking the district court to compel the defendants to produce additional patient files, Grant retained Ted Lodden, a certified public accountant, to determine whether the thirty-one file sample size provided by the defendants was

-4- representative of Zorn’s entire billing practice. Lodden did not independently calculate the statistical validity of the thirty-one file sample size. Nevertheless, he testified that extrapolation from the thirty-one files to the entirety of Zorn’s billing practice was appropriate.

The defendants subsequently filed a motion to exclude Lodden’s testimony under Daubert and Federal Rule of Evidence 702.
