Is Your Pay Plan Stark Compliant?

Is Your Pay Plan Stark Compliant?

Generally, the physician’s self-referral law (often referred to as “Stark”) prohibits a physician from referring a patient whose services may be reimbursed by a government payor (e.g., Medicare) for certain “Designated Health Services” (“DHS”) to an entity in which the physician or immediate family member of the physician has a financial relationship, unless an exception applies. “Designated Health Services” is defined to be ancillary goods or services reimbursed by Medicare, and include (i) clinical laboratory services, (ii) physical and occupational therapy services, (iii) radiology and other imaging services, and (iv) durable medical equipment. Stark defines DHS by reference to certain CPT codes, a list of which is published each year and can be found at

Physician practices that provide DHS implicate the Stark prohibitions because the physicians in the practice order tests, goods or services to be performed or provided by the practice. For example, if a physician orders lab tests to be performed by a laboratory that is owned by the practice, the Stark law is implicated. Same would be true for a cardiologist ordering imaging services to be done in-house, or an orthopedist ordering physical therapy services. In these examples, physicians would be referring tests to an entity (i.e., their practice) in which the physician owns an interest.

Like many regulatory paradigms, the prohibition is broadly defined, but exceptions carve out behavior that the government does not want to prohibit. While a deep dive into each exception is beyond the scope of this article, a prevalent exception for referrals within the same practice is the In-Office Ancillary Services Exception (IOASE). In order to rely on IOASE, a practice must meet the definition of a “group practice” under Stark. IOASE protects the in-office provision of certain DHS that are ancillary to the medical services provided by the physician practice. IOASE requires services to be personally provided by the referring physician, a physician-member of the same group practice as the referring physician, an individual who is supervised by the referring physician, or if the referring physician is a group practice, by another physician in the group practice, provided the supervision complies with all Medicare care payment/coverage rules for the services.

Second, IOASE requires that services be furnished in the same or centralized building. There are three alternative tests for this location requirement, but only one must be met. All three tests require the referring physician to have offices in the building that are open to patients a minimum number of hours per week and the physician must regularly practice medicine and furnish physician services for a minimum number of hours per week in that office. Additionally, IOASE requires the DHS to be billed by the physician group practice performing and supervising the services, or by an entity fully owned by the physician or the physician’s group practice (or by an independent third-party billing company acting as an agent for the group practice).

Compensation Arrangements
Regulations promulgated under Stark prohibit physicians from being paid based on the “volume or value” of their referrals of DHS. This has generally prohibited group practices from paying physicians based upon the specific orders or prescriptions for DHS provided by the group practice. Additionally, Stark regulations allow practices to split profits from DHS either on a share and share-alike basis, or based on the physician’s production excluding DHS compared to the production (excluding DHS) of other participating physicians in the practice.

New Regulations Clarify Physician Compensation
New regulations promulgated effective January 1, 2022 require compensation arrangements to meet certain criteria in order for the practice to enjoy the designation of a “group practice” under Stark.

The requirements for a group practice can be summarized as follows:

Notably, the oft-used method of carving out government payer business does not work. In order to enjoy the designation of a “group practice” under Stark, the services on which the productivity bonus is based cannot be DHS nor can they be DHS if they were payable under Medicare. Thus, pay plans that may once have been compliant may have fallen out of compliance.
