While reviewing NQF 0405 for configuration, we have noticed a discrepancy in the specification.
The top descriptive part says:
Denominator Exception:
Numerator 1: Patient did not receive PCP prophylaxis because there was a CD4 count above 200 cells/mm3 during the three months after a CD4 count below 200 cells/mm3
Numerator 2: Patient did not receive PCP prophylaxis because there was a CD4 count above 500 cells/mm3 or CD4 percentage above 15% during the three months after a CD4 count below 500 cells/mm3 or CD4 percentage below 15%
Numerator 3: None
eMeasure logic says:
Denominator Exceptions 1 =
AND: "Occurrence B of Laboratory Test, Result: CD4+ Count (result >= 200 per mm3)" <= 3 month(s) ends after end of "Occurrence A of Laboratory Test, Result: CD4+ Count"

Denominator Exceptions 2 =
AND:
OR: "Occurrence B of Laboratory Test, Result: CD4+ Count (result >= 500 per mm3)" <= 3 month(s) ends after end of "Occurrence A of Laboratory Test, Result: CD4+ Count"
OR: "Occurrence B of Laboratory Test, Result: CD4+ Percentage (result >= 15 %)" <= 3 month(s) ends after end of "Occurrence A of Laboratory Test, Result: CD4+ Percentage"
Two problems:
1. Description refers them as numerator 1, 2, 3... not a big deal
2. Description suggests Occurrence A result to be bellow 200 or bellow 500 or bellow 15% while eMeasure logic looks for any result no matter what is the result as long as it is under 3 month before > result.

Please let us know what is expected for Occurrence A.
