  sumhttp://hl7.org/fhir/us/cqfmeasures/CodeSystem/aggregate-methodSum

The measure score is determined by adding together the observations derived from the measure population.

~SUM
  averagehttp://hl7.org/fhir/us/cqfmeasures/CodeSystem/aggregate-methodAverage

The measure score is determined by taking the average of the observations derived from the measure population.

The measure score is determined by taking the median of the observations derived from the measure population.

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
