The Stark Law (42 U.S.C. § 1395nn) targets the financial incentive created when a referring physician stands to profit from the services the physician orders. It applies to a defined list of designated health services — such as clinical laboratory services, imaging, physical therapy, and durable medical equipment — billed to Medicare, and it prohibits both the referral and the entity's billing for the resulting service unless a statutory or regulatory exception is met.

What makes Stark distinctive is that it is a strict-liability statute: unlike the Anti-Kickback Statute, no proof of intent to induce referrals is required. A technical compliance failure in a compensation arrangement — a missed signature, an expired agreement, compensation that drifts from fair market value — can trigger liability even where nobody intended wrongdoing. Common exceptions used to structure compliant arrangements include the in-office ancillary services exception and the bona fide employment exception, and CMS maintains a voluntary self-disclosure protocol for entities that discover a violation.

Because Stark removes intent from the equation, a simulation of exposure should treat the compliance-failure branch as close to deterministic once the underlying facts are fixed, rather than blending in a scienter-based probability. Juricratic models this by letting a user separate the strict-liability Stark exposure from any parallel Anti-Kickback Statute branch, which does carry an intent dial, so the two theories don't get collapsed into one blended probability that misstates either.

Health system compliance counsel uses the Stark framework to audit physician compensation arrangements against the applicable exceptions before a referral pattern is challenged, and litigators defending a False Claims Act suit predicated on a Stark violation focus fact discovery on the mechanical exception elements rather than intent, since intent is not a defense.
