This report appeared in late December 2022 here.
Since PAMA 2014, the OIG has been tasked with producing an annual report on lab industry spending in Medicare (both Part B labs and hospital outpatient labs).
I noticed today, the CY2021 report, which normally would appear in Fall 2022, is calendared to appear in 2023 this time. So it's later than typical years.
See my October 29 report on the horrifyingly abnormal Part B spending on literally bizarre genetic test patterns in CY2021, based on my analysis of newly released CMS raw data for CY2021. Here.
