I am trying to understand how patients fall into the numerator for PC-07 eCQM.  For the month of May I have 4 cases that met the numerator and 2 additional who have met the Stratum 1 for the numerator.  The 4 who met the numerator all show procedure 30233N1 performed (blood transfusion).  The 2 that met Stratum 1 also had this procedure performed.  I have downloaded the diagnosis and procedure files from VSAC for Severe Maternal Morbidity.  There are no codes in this file for blood transfusion.  There are also no codes for "other immediate postpartum hemorrhage", which is the reason for the blood transfusion.  So, I do not understand how these 4 are pulling into the numerator and others are not.  Per instructions on the eCQI Resource Center webpage I am using 2.16.840.1.113762.1.4.1029.255 and 2.16.840.1.113762.1.4.1029.256.  Can you please help me to understand this?  Thank you.
