UNITED STATES DISTRICT COURT DISTRICT OF MINNESOTA

United States of America and the State of Civil No. 22-602 (DWF/JFD) Minnesota, ex rel. Ashley Mothershed,

Plaintiffs,

v. MEMORANDUM OPINION AND ORDER Mayo Clinic Ambulance,

Defendant.

INTRODUCTION This matter is before the Court on Defendant Mayo Clinic Ambulance’s (“Mayo”) motion to dismiss Relator Ashley Mothershed’s second amended complaint. (Doc. No. 74.) Relator opposes the motion. (Doc. No. 83.) For the reasons set forth below, the motion is granted in part and denied in part. BACKGROUND Mothershed is an experienced professional in ambulance coding compliance. (Doc. No. 72, Second Am. Compl. (“SAC”) ¶¶ 4, 15-21.) Mayo is a Minnesota-based, non-profit organization that provides ambulance transport services in both Minnesota and Wisconsin. (Id. ¶¶ 25-26.) In November 2020, Mothershed began working remotely for Mayo’s billing department. (Id. ¶¶ 12-14.) She worked for Mayo from November 2020 through June 2021, and then again from September 2021 through May 2022. (Id. ¶¶ 12, 14.) As a biller in Mayo’s billing department, Mothershed used information from patient care reports to enter appropriate billing codes into Mayo’s RescueNet billing software. (Id. ¶¶ 40, 133.) The information from RescueNet was first reviewed by Mayo’s billing supervisors and then automatically inputted into the appropriate form for

submission to a government healthcare payor for reimbursement. (Id. ¶¶ 40, 135, 138.) During her time with Mayo, Mothershed noticed that Mayo had a practice of submitting allegedly false claims to federal and Minnesota-state healthcare payors. (Id. ¶ 2.) Mothershed frequently reported the improper billing practices to her supervisors, but they would tell her she was wrong and instruct her to continue billing in the same manner. (Id.

¶ 42.) On one occasion, Mothershed’s supervisor warned her to “drop her complaints or else.” (Id. ¶ 143.) Similarly, one of Mothershed’s coworkers also raised concerns about false billing practices and received similar push back from their supervisors. (Id. ¶ 146.) Ambulance services providers may seek reimbursement from federal or Minnesota-state healthcare payors so long as (1) the transport was medically necessary,

meaning that “the use of other methods of transportation is contraindicated by the individual’s condition,” (2) they use the Centers for Medicare and Medicaid Services’ (“CMS”) billing codes, and (3) the billing code reflects the level of service that was actually provided. 42 U.S.C. § 1395x(s)(7); 42 C.F.R. §§ 410.40(e)(1), 410.41(c); see also CMS, Pub. No. 100-02, Medicare Benefit Policy Manual, ch. 10, §§ 10.2, 10.2.2

(2018), https://www.cms.gov/regulations-and- guidance/guidance/manuals/downloads/bp102c10.pdf.1

1 Minnesota’s Medical Assistance program follows the Medicare criteria for reimbursement of ambulance services. Minn. Stat. § 256B.0625, subdiv. 17a(a). The Mothershed alleges that Mayo had three schemes for submitting false claims: (1) failing to review whether ambulance transports were medically necessary; (2) inaccurately reporting the level of services provided by upcoding non-emergency

transports to emergency transports; and (3) inaccurately reporting the level of services provided by upcoding basic life support (“BLS”) services to advanced life support (“ALS”) services. (SAC ¶ 2.) The Court describes each of these alleged schemes and the applicable regulations in further detail below. I. Alleged Scheme 1: Failure to Consider Medical Necessity

Government healthcare payors only reimburse ambulance transports that are medically necessary, meaning that “the use of other methods of transportation is contraindicated by the individual’s condition.” 42 U.S.C. § 1395x(s)(7). Other methods of transportation are not contraindicated if “some means of transportation other than an ambulance could be used without endangering the individual’s health, whether or not

such other transportation is actually available.” CMS, Pub. No. 100-02, Medicare Benefit Policy Manual, ch. 10, § 10.2.1 (2018). Medical necessity is presumed when the patient was transported in an emergent situation (such as an accident, injury, or acute illness),

TRICARE/CHAMPUS and Federal Employees’ Health Benefits programs also have similar requirements to Medicare. See 32 C.F.R. §§ 199.2, 199.4(d)(3)(v); Off. of Pers. Mgmt., Frequently Questioned Services, https://www.opm.gov/retirement- center/publications-forms/benefits-administration-letters/2017/17-401a3.pdf (last visited Jan. 13, 2025). Given the similarities, the parties have primarily referred to the Medicare requirements throughout their filings. The Court does the same for the purposes of this motion. was unconscious, required emergency treatment during transport, or was bed-confined before and after the transport. Id. § 20. If a provider submits a claim to a government healthcare payor,2 they must

determine whether the transport was medically necessary. CMS, Pub. No. 100-04, Medicare Claims Processing Manual, ch. 15, § 30.2.4 (2024), https://www.cms.gov/regulations-and- guidance/guidance/manuals/downloads/clm104c15.pdf. When a transport was not medically necessary, the provider must include a “GY” modifier with the billing code.

Id. If a GY modifier is used, the government healthcare payor will deny the claim. Id. Consequently, the ambulance entity must seek reimbursement from the patient or the patient’s private insurance. Id. Mothershed alleges that Mayo’s general practice was to not review medical necessity, instead leaving the default billing assumption that transports were medically

necessary. (SAC ¶¶ 69, 73, 76.) During training, Mothershed was told by her trainer that Mayo did not use GY modifiers. (Id. ¶ 78.) When Mothershed asked her trainer and a supervisor if they had ever determined that a transport was not medically necessary, they each said they had not. (Id. ¶ 79.) Mothershed repeatedly confronted her supervisors about this practice and each time was told that Mayo did not review medical necessity.

(Id. ¶¶ 81-84, 95.) Mothershed was once instructed to add the GY modifier to a transport

2 Providers do not have to submit claims to government healthcare payors for services that are excluded under the statute. CMS, Pub. No. 100-04, Medicare Claims Process Manual, ch. 15, § 30.2.4 (2024). When they choose to submit such claims to a government healthcare payor, they must use the GY modifier. at the instruction of her supervisor because the patient specifically requested it. (Id. ¶ 77 n.5; see also Doc. No. 78 (“Sertich Decl.”) ¶ 17, Ex. 16.) Mothershed provides four specific examples of this practice. Patient MN-2 was

transported to the hospital by Mayo after a 911 call. (Sertich Decl. ¶ 4, Ex. 3 at 2.) The patient had tripped and fallen the previous day and reported back pain. (Id. at 4.) She was alert, oriented, and able to stand and walk. (Id. at 4-5.) She was legally blind and reported that her caretaker had left for the weekend. (Id. at 4.) Mayo billed the transport without the GY modifier, indicating that it was medically necessary. (SAC ¶ 88.)

Patient MN-6 was transported to the hospital by Mayo after a 911 call. (Sertich Decl. ¶ 5, Ex. 4 at 2.) The patient had visited Mayo Clinic earlier that day, but after returning home she began experiencing weakness and confusion and was unable to leave her wheelchair. (Id.
