CMS9 measure was 100% passing with 100% coverage early last week. Today, it shows 100% passing with 96% coverage. We have not update any test cases nor measure upload. We notice the reason of 4% not covered is in the following logic with words of "start during" and "exist" (see highlighted ones below).

define "Single Live Birth Encounter Without Galactosemia or Parenteral Nutrition":
"Single Live Birth Encounter" SingleLiveBirthEncounter
without ["Diagnosis": "Galactosemia"] Galactosemia
such that Galactosemia.prevalencePeriod starts during SingleLiveBirthEncounter.relevantPeriod
without ["Procedure, Performed": "Parenteral Nutrition"] ParenteralNutrition
such that ParenteralNutrition.relevantPeriod starts during SingleLiveBirthEncounter.relevantPeriod
where not exists ( SingleLiveBirthEncounter.diagnoses EncounterDiagnoses
where EncounterDiagnoses in "Galactosemia"
)
