Valuation of Diagnostic Imaging: Regulatory Environment

Outpatient enterprises, including imaging centers, are some of the most regulated healthcare entities in the U.S., with federal, state, and local regulators, laws, and agencies overseeing providers to ensure the safety of patients.1 This regulatory environment constrains the market for all freestanding diagnostic imaging centers, represents a significant administrative burden, is a business risk factor, and also acts as a barrier to entry for new market entrants.

Federal Fraud and Abuse Laws

Healthcare organizations face a range of federal and state legal and regulatory constraints, which affect their formation, operation, procedural coding and billing, and transactions. Fraud and abuse laws, specifically those related to the federal Anti-Kickback Statute (AKS) and physician self-referral laws (the “Stark Law”), may have the greatest impact on the operations of healthcare organizations.

The AKS and Stark Law are generally concerned with the same issue – the financial motivation behind patient referrals. However, while the AKS is broadly applied to payments between providers or suppliers in the healthcare industry and relates to any item or service that may be paid for under any federal healthcare program, the Stark Law specifically addresses the referrals from physicians to entities with which the physician has a financial relationship for the provision of defined services that are paid for by the Medicare program.2 Additionally, while violation of the Stark Law carries only civil penalties, violation of the AKS carries both criminal and civil penalties.3

Anti-Kickback Statute

The AKS makes it a felony for any person to “knowingly and willfully” solicit or receive, or to offer or pay, any “remuneration”, directly or indirectly, in exchange for the referral of a patient for a healthcare service paid for by a federal healthcare program,4 even if only one purpose of the arrangement in question is to offer remuneration deemed illegal under the AKS.5 Notably, a person need not have actual knowledge of the AKS or specific intent to commit a violation of the AKS for the government to prove a kickback violation,6 only an awareness that the conduct in question is “generally unlawful.”7 Further, a violation of the AKS is sufficient to state a claim under the False Claims Act (FCA).8

Criminal violations of the AKS are punishable by up to ten years in prison, criminal fines up to $100,000, or both, and civil violations can result in administrative penalties, including exclusion from federal healthcare programs, and civil monetary penalties plus treble damages (or three times the illegal remuneration).9 In addition to the civil monetary penalties paid under the AKS, if the AKS violation triggers liability under the FCA, defendants can incur additional civil monetary penalties of $13,508 to $27,018 per violation, plus treble damages.10

Due to the broad nature of the AKS, legitimate business arrangements may appear to be prohibited.11  In response to these concerns, Congress created a number of statutory exceptions and delegated authority to HHS to protect certain business arrangements by means of promulgating several safe harbors.12 These safe harbors set out regulatory criteria that, if met, shield an arrangement from regulatory liability, and are meant to protect transactional arrangements unlikely to result in fraud or abuse.13 Failure to meet all of the requirements of a safe harbor does not necessarily render an arrangement illegal.14 It should be noted that, in order for a payment to meet the requirements of many AKS safe harbors, the compensation must not exceed the range of fair market value and must be commercially reasonable.

Stark Law

The Stark Law prohibits physicians from referring Medicare patients to entities with which the physicians or their family members have a financial relationship for the provision of designated health services (DHS).15 Further, when a prohibited referral occurs, entities may not bill for services resulting from the prohibited referral.16 Under the Stark Law, DHS include, but are not limited to, the following:

  1. Radiology and certain other imaging services;
  2. Inpatient and outpatient hospital services;
  3. Radiation therapy services and supplies;
  4. Certain therapy services, such as physical therapy;
  5. Durable medical equipment; and,
  6. Outpatient prescription drugs.17

Under the Stark Law, financial relationships include ownership interests through equity, debt, other means, and ownership interests in entities also have an ownership interest in the entity that provides DHS.18 Additionally, financial relationships include compensation arrangements, which are defined as arrangements between physicians and entities involving any remuneration, directly or indirectly, in cash or in kind.19

Civil penalties under the Stark Law include overpayment or refund obligations, a potential civil monetary penalty of $15,000 for each service, plus treble damages, and exclusion from Medicare and Medicaid programs.20  Further, similar to the AKS, violation of the Stark Law can also trigger a violation of the FCA.21

Notably, the Stark Law contains a large number of exceptions, which describe ownership interests, compensation arrangements, and forms of remuneration to which the Stark Law does not apply.22 Similar to the AKS safe harbors, without these exceptions, the Stark Law may prohibit legitimate business arrangements. It must be noted that in order to meet the requirements of many exceptions related to compensation between physicians and other entities, compensation must: (1) not exceed the range of fair market value; (2) not take into account the volume or value of referrals generated by the compensated physician; and, (3) be commercially reasonable. Unlike the AKS safe harbors, an arrangement must fully fall within one of the exceptions in order to be shielded from enforcement of the Stark Law.23

Medicare Accreditation

Prior to receiving Medicare payment for the technical component services,24 diagnostic imaging centers must become accredited by a CMS-approved organization as an Advanced Diagnostic Imaging (ADI) Supplier.25 Certain regulatory requirements that must be met in order to become accredited include, but may not be limited to, the following areas:

  1. Staff qualifications;
  2. Equipment standards and safety;
  3. Safety of patients, family, and staff;
  4. Medical records; and,
  5. Patient privacy.26

CMS has approved the following four organizations to accredit ADI suppliers: (1) ACR; (2) Intersocietal Accreditation Commission (IAC); (3) RadSite; and, (4) The Joint Commission.27  After receiving initial approval, ADI suppliers are then subject to triennial surveys.28 In addition to these federal requirements, diagnostic imaging centers are also required to meet any and all state licensure requirements.

Diagnostic imaging centers face many obstacles within the regulatory environment that can prohibit their formation, growth, and development. Understanding fraud and abuse laws, among other statutes and regulations, are integral to the success of a diagnostic imaging center. Another factor integral to the success of a diagnostic imaging center is the usage of medical imaging devices. Consequently, the final installment in this series will discuss the technological environment in which diagnostic imaging centers operate.
