Thank you for your question regarding CMS22v11 Preventive Care and Screening: Screening for High Blood Pressure and Follow-Up Documented . 'Active' is a logic term that refers to a diagnosis that has not been 'resolved.' To answer your question, one would need to know the time the hypertension diagnosis (active, not resolved) was entered and the time the qualifying encounter began. As an example, if the hypertension diagnosis is entered on 11/30/23 at 11:00 AM but the qualifying encounter began 11/30/23 at 10:59 AM and ended at 11:28 AM, then the case would not meet the requirements for the denominator exclusion. If the diagnosis is entered any time before the start of the qualifying encounter and is active in your system, then the case would meet the measure's denominator exclusion criteria. Using your example, a diagnosis with 'occur date' 11/25/23 would meet denominator exclusion criteria. Please let us know if you need additional clarification. Thank you.
