Denominator exclusion

A denominator exclusion is a case that the measured entity removes from the denominator before evaluating the numerator criteria. Denominator exclusions help narrow the denominator to the appropriate population. Proportion and ratio measures use denominator exclusions for this purpose.

For example, a measure may exclude patients with bilateral lower extremity amputations from the denominator of a measure that requires foot exams.

Continuous variable measures may use denominator exclusions but may instead use the term measure population exclusion.
