Hi,

For CMS55, a patient named"3 N SCIP" has encounter 1 as 

  <high value='20140512050000'/>

and another encounter 2 as

  <high value='20140520100000'/>

So, the second encounter is only considered for measure calculation wherein Cypress says all visits should fall under measure calculation (atleast IPP) PFA the patients file 31_3_N SCIP.txt

Hi-

You may be having an issue with how you are evaluating specific occurrences. This statement is from section 2.8.5 of the Quality Data Model version 4.2, "Conditions applied to specific occurrences carry forward from one population to the next, in the order in which they are calculated. See the eCQM Logic and Implementation Guidance5 for details on the calculation order of the measures."

The Patient "3 N SCIP" has three encounters with code 32485007 from the Encounter Inpatient valueset (2.16.840.1.113883.3.666.5.307). All three of these encounters satisfy the ("length of stay <= 120 day(s)" and "ends during Measurement Period") conditions.

Encounter 1 - January 29-31 Encounter 2 - May 8-12 Encounter 3 - May 12-20

As a result, this patient has a count of 3 visits for the IPP.

None of the encounters are within an hour of an Emergency Department visit, and therefore are not in the Measure Population.
