Brief description of measure CMS646: Intravesical Bacillus-Calmette-Guerin for non-muscle invasive bladder cancer: Percentage of patients initially diagnosed with non-muscle invasive bladder cancer and who received intravesical Bacillus-Calmette-Guerin (BCG) within 6 months of bladder cancer staging. CMS771: Urinary Symptom Score Change 6-12 Months After Diagnosis of Benign Prostatic Hyperplasia: Percentage of patients with an office visit within the measurement period and with a new diagnosis of clinically significant Benign Prostatic Hyperplasia who have International Prostate Symptoms Score (IPSS) or American Urological Association (AUA) Symptom Index (SI) documented at time of diagnosis and again 6-12 months later with an improvement of 3 points. Description of issue Measurement Period should be updated to "day of Measurement Period" to harmonize with other measures and as a consideration for the transition to FHIR. Goal of review Obtain technical feedback

Proposed solution ​Revise logic to include "day of Measurement Period" instead of "Measurement Period". CMS646 CURRENT LOGIC: define "Has Qualifying Encounter"   exists ["Encounter, Performed": "Office Visit"] ValidEncounter     where ValidEncounter.relevantPeriod during "Measurement Period"       and ValidEncounter.class !~ "virtual" PROPOSED LOGIC: define "Has Qualifying Encounter"   exists ["Encounter, Performed": "Office Visit"] ValidEncounter      where ValidEncounter.relevantPeriod during day of "Measurement Period"        and ValidEncounter.class !~ "virtual" CMS771: CURRENT LOGIC: define "BMI Exam Result Greater Than or Equal To 40 During Measurement Period and On or Before Follow Up USS Assessment"    exists[...]            and Global.EarliestOf(BMIExam.relevantDatetime, BMIExam.relevantPeriod)during "Measurement Period"            and Global.EarliestOf(BMIExam.relevantDatetime, BMIExam.relevantPeriod)on or before FollowUpUSSAssessment.assessmentDatetime        return Global.EarliestOf(BMIExam.relevantDatetime, BMIExam.relevantPeriod)) define "Has Qualifying Encounter"   exists ["Encounter, Performed": "Office Visit"] ValidEncounter     where ValidEncounter.relevantPeriod during "Measurement Period"       and ValidEncounter.class !~ "virtual" PROPOSED LOGIC:   define "BMI Exam Result Greater Than or Equal To 40 During Measurement Period and On or Before Follow Up USS Assessment"    exists[...]         and Global.EarliestOf(BMIExam.relevantDatetime, BMIExam.relevantPeriod)during day of "Measurement Period"         and Global.EarliestOf(BMIExam.relevantDatetime, BMIExam.relevantPeriod)on or before FollowUpUSSAssessment.assessmentDatetime     return Global.EarliestOf(BMIExam.relevantDatetime, BMIExam.relevantPeriod)) define "Has Qualifying Encounter"    exists ["Encounter, Performed": "Office Visit"] ValidEncounter        where ValidEncounter.relevantPeriod during day of "Measurement Period"          and ValidEncounter.class !~ "virtual" Rationale for change ​Revising the timing harmonizes with the approach across measures, and aligns with the measure intent.
