I am testing CMS 160 using cypress test with cypress 2.7.0 and reporting year 2014 (2015 measures).
This test expects 4 patients in denominator for CMS160 in duration Sep-Dec. As per our calculations we are getting only 2 patients.
After looking at data, I found out, that cypress expects Depression Diagnosis from previous year Oct 2013 (out of measurement period) to be considered as valid while specification states that "Depression Diagnosis" must overlap an encounter which occurs during measurement period (in this case Sep-Dec 2014)
