Contingency management (CM) is a form of intervention treatment program that incentivizes patients with substance use disorders to observe certain conditions—such as non-use of drugs or alcohol confirmed via urine drug screening or breathalyzer test, or even drug therapy adherence—in exchange for something of monetary value.  Adherence is often tracked and confirmed by those that provide the incentive payment through digital health technologies—including apps that can be downloaded to the patient’s smart phone or that are already downloaded to a smart phone provided to the patient as part of a CM program.  While many contend that CM is an effective, evidence-based treatment, certain legal barriers limit, and often prevent, its widespread adoption and use.  When there is the potential for patients to receive items and services payable by Federal health care programs (FHCPs), CM incentives are subject to scrutiny under the Federal anti-kickback statute (AKS) and the Beneficiary Inducements CMP.  A recent advisory opinion issued by the United States Department of Health and Human Services (HHS), Office of Inspector General (OIG), approved a digital health company’s offer to provide cash equivalents to patients participating in a CM program.  This favorable result continues to demonstrate OIG’s flexibility notwithstanding regulatory precedent or guidance appearing to the contrary.
