Talking and tackling Risk-Based QC Plans

The clock is ticking down for EQC. CMS stated in an initial memo on EP23 that Risk-based QC would replace EQC protocols at the end of 2013, and that by 2014, EQC would no longer be an acceptable laboratory procedure. While the CLSI EP23 protocol has been out for more than a year, though, CMS has yet to issue any regulations or guidelines on how to implement, comply, or inspect Risk QC. What's going on?
