Hi team,

We would require some clarity regarding the calculation of performance rate of measure CMS871v2- Severe Hyperglycemia.

In the measure guidance it is mentioned that to determine the measure outcome, the total number of hyperglycemic days during the inpatient hospitalization is divided by the total number of eligible hospital days of the inpatient hospitalization.

Our question here is, should we consider multiple inpatient hospitalization encounters in a measurement period while evaluating the measure to achieve total number of hyperglycemic events or it is just the hyperglycemic events which has occurred in one specific encounter.

Incase hyperglycemic events are considered for each inpatient hospitalization encounter, we have further questions as below.

If the patient has multiple hospitalizations, for example 3 encounters and each encounter has respective associated numerator and denominator measure observations as per the screen shot below.

We would like to understand how the ultimate measure outcome is calculated here?
