Lock-In Program

The Texas health care community plays a critical role in preventing prescription misuse through participation in the Medicaid Lock-In Program, administered by the OIG. Through the MLIP, the OIG reviews referrals and data to determine if a Medicaid client meets the criteria for lock-in to a single designated pharmacy or prescriber.
