included in the numerator data.

XXXIII. DENOMINATOR EXCEPTIONS
Enter a description of the denominator exceptions for the eMeasure.
Denominator exceptions are those conditions that should remove a patient, procedure or unit of
measurement from the denominator only if the numerator criteria are not met. Denominator
exceptions allow for adjustment of the calculated score for those providers with higher risk populations.
Denominator exceptions are used only in proportion eMeasures. They are not appropriate for ratio,
continuous variable, or cohort eMeasures.
Denominator exceptions allow for the exercise of clinical judgment and should be specifically defined
where capturing the information in a structured manner fits the clinical workflow. Generic denominator
exception reasons used in proportion eMeasures fall into three general categories: medical reasons,
patients’ reasons, and system reasons.
For proportion measures that do not have denominator exceptions, enter ’None’.
