  div: This case-sensitive code system http://terminology.hl7.org/CodeSystem/measure-population defines the following codes: Code Display Definition initial-population 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 Numerator The numerator statement describes the process, condition, event, or outcome that satisfies the measure’s focus or intent. The numerator statement includes parameters such as: *the Event or events that will satisfy the numerator inclusion criteria *the Performance period or time interval in which the numerator event must occur, if it is different from that used for identifying the denominator.

Numerator exclusions are used in proportion and ratio measures to help narrow the numerator (for inverted measures). denominator 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. denominator-exclusion Denominator Exclusion Denominator exclusion criteria define patients, subjects, or events that should be excluded from the denominator.

    v: Initial Population
  definition:
    v: 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.

    v: Numerator
  definition:
    v: The numerator statement describes the process, condition, event, or outcome that satisfies the measure’s focus or intent. The numerator statement includes parameters such as: *the Event or events that will satisfy the numerator inclusion criteria *the Performance period or time interval in which the numerator event must occur, if it is different from that used for identifying the denominator.

  display:
    v: Numerator Exclusion
  definition:
    v: 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).
concept:
  code:
    v: denominator
  display:
    v: Denominator
  definition:
    v: 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.
concept:
  code:
    v: denominator-exclusion
  display:
    v: Denominator Exclusion
  definition:
    v: 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.
concept:
  code:
    v: denominator-exception
  display:
    v: Denominator Exception
  definition:
    v: 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.

  code:
    v: measure-population
  display:
    v: Measure Population
  definition:
    v: 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.
concept:
  code:
    v: measure-population-exclusion
  display:
    v: Measure Population Exclusion
  definition:
    v: 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.
concept:
  code:
    v: measure-observation
  display:
    v: Measure Observation
  definition:
    v: 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.
