    Benchmarks

    • No scoring benchmark currently exists for this QCDR measure.
    • If 19 or fewer physicians each report the measure or 20 physicians do not report the measure on at least 60 percent of qualifying patients, and a minimum of 20 patients, you will earn 3 out of 10 points toward your total quality score. Choose measures assuming you’ll only earn 3 points per QCDR measure.
    • If at least 20 physicians report the measure on at least 60 percent of qualifying patients and at least 20 patients, CMS will develop a scoring benchmark using data collected during the 2018 reporting year.
