Code  System  Display  Definition 
initialpopulation  http://terminology.hl7.org/CodeSystem/measurepopulation  Initial Population  The initial population criteria refers to all patients, subjects, or events to be evaluated by a quality measure involving patients or subjects who share a common set of specified characterstics. All patients, subjects, or events counted (for example, as numerator, as denominator) are drawn from the initial population. 
numerator  http://terminology.hl7.org/CodeSystem/measurepopulation  Numerator  Numerator criteria define the patients, subjects, or events that should be included in the upper portion of a fraction used to calculate a rate, proportion, or ratio. Also called the measure focus, it is the target process, condition, event, or outcome. Numerator criteria are the processes or outcomes expected for each patient, subject, or event defined in the denominator. A numerator statement describes the clinical action that satisfies the conditions of the measure. 
numeratorexclusion  http://terminology.hl7.org/CodeSystem/measurepopulation  Numerator Exclusion  Numerator exclusion criteria define patients, subjects, or events to be excluded from the numerator. Numerator exclusions are used in proportion and ratio measures to help narrow the numerator (for inverted measures). 
denominator  http://terminology.hl7.org/CodeSystem/measurepopulation  Denominator  Denominator criteria define the patients, subjects, or events that should be included in the lower portion of a fraction used to calculate a rate, proportion, or ratio. The denominator can be the same as the initial population, or a subset of the initial population to further constrain the population for the purpose of the measure. 
denominatorexclusion  http://terminology.hl7.org/CodeSystem/measurepopulation  Denominator Exclusion  Denominator exclusion criteria define patients, subjects, or events that should be excluded from the denominator. Denominator exclusions are used in proportion and ratio measures to help narrow the denominator. For example, patients with bilateral lower extremity amputations would be listed as a denominator exclusion for a measure requiring foot exams. 
denominatorexception  http://terminology.hl7.org/CodeSystem/measurepopulation  Denominator Exception  Denominator exceptions are conditions that should remove a patient, subject, or event from the denominator of a measure only if the numerator criteria are not met. Denominator exception allows for adjustment of the calculated score for those providers with higher risk populations. Denominator exception criteria are only used in proportion measures. 
measurepopulation  http://terminology.hl7.org/CodeSystem/measurepopulation  Measure Population  Measure population criteria define the patients, subjects, or events for which the individual observation for the measure should be taken. Measure populations are used for continuous variable measures rather than numerator and denominator criteria. 
measurepopulationexclusion  http://terminology.hl7.org/CodeSystem/measurepopulation  Measure Population Exclusion  Measure population exclusion criteria define the patients or events that should be excluded from the measure population before determining the outcome of one or more continuous variables defined for the measure observation. Measure population exclusion criteria are used within continuous variable measures to help narrow the measure population. 
measureobservation  http://terminology.hl7.org/CodeSystem/measurepopulation  Measure Observation  Measure observation criteria are used to define an individual observation to be performed for each patient, subject, or event in the measure population. Measure observations for each case in the population are aggregated to determine the overall measure score for the population.

Explanation of the columns that may appear on this page:
Lvl  A few code lists that FHIR defines are hierarchical  each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy  see Code System for further information 
Source  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). If the code is in italics, this indicates that the code is not selectable ('Abstract') 
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
