Thank you for the opportunity to clarify our intent. The two codes are intended to represent two distinct concepts. In Elective Delivery, the measure evaluates care provided to the mother. As the subject is the mother, the relevant action is delivery. From a workflow perspective, estimated gestational age at delivery could and should be documented in the mother’s chart well before the delivery event, and should be considered when planning an elective delivery. In Breast Milk Feeding, the subject is the newborn and the action is birth. This information would be recorded in the infant’s record, not the mother’s. We would be interested in feedback from the field on how this information is documented in mother vs. baby records and whether the use of these codes is viewed as semantically distinct.
