Anti-Kickback Statute

A federal criminal law (42 U.S.C. 1320a-7b(b)) that prohibits knowingly offering, paying, soliciting, or receiving any remuneration, directly or indirectly, in exchange for referring patients or arranging services covered by federal health programs including Medicare and Medicaid. Unlike Stark Law, the Anti-Kickback Statute is an intent-based statute and applies to any type of healthcare provider, not just physicians. Violations are criminal offenses that can result in imprisonment, exclusion from federal programs, and civil monetary penalties.

Why this matters for your clinic

The Anti-Kickback Statute covers a broad range of business relationships: consulting arrangements, management service agreements, medical director contracts, marketing agreements, and joint ventures. Any arrangement where something of value flows between parties who have a referral relationship requires scrutiny under AKS. The OIG's safe harbor regulations define categories of arrangements that are protected from AKS prosecution if they satisfy specific criteria.

Safe harbors are key. Common safe harbors include personal services and management contracts (with a written agreement, set in advance, for fair market value services), employment arrangements (for bona fide employees at fair market value), and investment interests in large publicly traded entities. Each safe harbor has technical requirements. An arrangement that almost fits a safe harbor but fails one criterion is not protected.

The OIG annually updates its Work Plan to identify business arrangements it intends to scrutinize. Clinic owners entering into contracts with vendors, management companies, or physician groups that have a referral relationship should have healthcare counsel review those contracts against both Stark and AKS before executing them.

What good looks like

HHS OIG publishes comprehensive AKS safe harbor regulations and advisory opinions that address specific arrangements. The 2021 AKS regulatory update created new safe harbors for value-based care arrangements and cybersecurity technology donations. OIG advisory opinions are binding on the parties requesting them and serve as persuasive precedent for similar arrangements.

Example

A home health agency offers to pay a physician group a $500 per referral fee for every patient referred to their home health services. This is a straightforward AKS violation. A subtler version: the same agency offers below-market office space to the physician group as part of a co-location arrangement that was negotiated after a referral relationship was established. If the below-market rent is intended to reward referrals, it is also an AKS violation even though it is structured as a rental payment.

From Sorso

Our role is financial, not legal, but every engagement that involves a management agreement, medical directorship, or vendor relationship with a referral dimension gets flagged for healthcare legal review. The cost of a legal review is trivial relative to the financial and criminal exposure of an unreviewed arrangement.
