It seems to be the intention of CMS529v0 to capture the first set of relevant data within the measurement period, however my analysis of the measure logic doesn't seem to align with this.

When I look at the logic for the numerator, the acute care hospital Inpatient encounter doesn't seem to be restricted to the measurement period. Because of this, it is likely that the preconditions within the numerator will select events which fall outside of the measure period if such data exists for the measure to consider. This is due to the FIRST restriction. This restriction will make it impossible for patients to qualify for the numerator.

This is my understanding of the measure. It does not seem that the measure logic aligns with the intention in this case. I would like some guidance on this measure.
