Massachusetts-based DUSA Pharmaceuticals, Inc. (DUSA), a subsidiary of Sun Pharmaceutical Industries, Inc. (Sun Pharma), has agreed to pay the United States $20.75 million to resolve allegations that DUSA caused physicians to submit false claims to Medicare and the Federal Employee Health Benefit Program by knowingly promoting an administration process for the drug Levulan Kerastick that contradicted the product instructions approved by the U.S. Food and Drug Administration (FDA) and was unsupported by sufficient clinical evidence.
