The Centers for Medicare and Medicaid Services (CMS) recently issued Phase II of the Final Regulations to implement and enforce the federal physician self-referral law (otherwise known as the “Stark Law”). The Stark Law generally affects all business relationships between physicians and other health care providers. Physician practices should review all aspects of their business operations to ensure that they will not be subject to fines or penalties under the Stark Law for making a referral prohibited by the Stark Law.
