Enhancements Needed in the Tracking and Collection of Medicare Overpayments Identified by ZPICs and PSCs September 29, 2017 Medicare 0 This study continues OIG's body of work examining overpayments made by Medicare. Overpayments can be identified by a number of key players including providers and Medicare contractors. Recovering overpayments is critical to reducing improper payments in the Medicare program.
