This is actually regarding CMS 165v4, but that is not an option in the EP measure selector.
The numerator definition has been changed to the following:
AND: Most recent: ◾"Occurrence A of Encounter, Performed: Adult Outpatient Visit" satisfies all ◾overlaps "Occurrence A of Diagnosis, Active: Essential Hypertension"
◾during "Measurement Period"
◾overlaps "Physical Exam, Performed: Diastolic Blood Pressure (result)"
◾overlaps "Physical Exam, Performed: Systolic Blood Pressure (result)"
◦ AND: "Physical Exam, Performed: Diastolic Blood Pressure" satisfies all ◾Most recent: during "Occurrence A of Encounter, Performed: Adult Outpatient Visit"
◾ (result < 90 mmHg)
◦ AND: "Physical Exam, Performed: Systolic Blood Pressure" satisfies all ◾Most recent: during "Occurrence A of Encounter, Performed: Adult Outpatient Visit"
◾ (result < 140 mmHg)
If we are interpreting the HQMF correctly, the algorithm can be restated as:
Take the most recent encounter during MP during which the patient had bp recorded and diagnosis of hypertention.
Take the last bp sys and dias reading from that encounter.
Include patient if sys < 140 and dias < 90.
This represents a change since version 3 in the following aspects:
1. The hypertension diagnosis must overlap with the encounter, when in version 3 it only had to overlap the measurement period.
2. Version 3 evaluated the latest encounter for bp below a threshold. Version 4 evaluates the latest encounter with a bp recorded for bp below the threshold. Meaning version 3 would count the last encounter even if no bp was recorded.
Our questions are:
1. Are we interpreting the new language correctly?
2. Were the changes intentional?
3. If the changes are intentional, why don't they appear in the guidance?
