9.15.2021 General Guideline 33: Race and Ethnicity Stratification May supplemental data be used for race and ethnicity stratifications?

Yes. Supplemental data may be used to identify race and ethnicity when stratifying the eligible population.

9.15.2021 PCS Questions Do answers from the Policy Clarification Support system have an expiration date?

We recommend that organizations not use PCS responses that are over 3 years old. If a question relates directly to a measure specification or a general guideline that was revised from a previous measurement year, we recommend resubmitting the question.

9.15.2021 Acute Hospital Utilization, Emergency Department Utilization and Hospitalization for Potentially Preventable Complications May covariance values be rounded before using them in the variance calculation?

No. Do not round covariance values for use in variance calculations. Member-level PPD and PUCD should be unrounded in covariance and variance calculations, although truncation to 10 decimal points is applied, per the previous step. NCQA intends to evaluate truncation and rounding logic throughout intermediate calculations to ensure consistency and reduce potential bias in a future publication release.

9.15.2021 Follow-Up After Emergency Department Visit for Substance Use (FUA) It appears that the medication tables for the Alcohol Use Disorder Treatment Medications List and the Opioid Use Disorder Treatment Medications List needed to identify pharmacotherapy dispensing events in the numerator are not included in the FUA measure. Where can they be found?

The medication tables for the Alcohol Use Disorder Treatment Medications List and the Opioid Use Disorder Treatment Medications List were inadvertently omitted from the measure specifications. The full medication lists are included in the MY 2022 Medication List Directory (MLD). The medication tables can also be found in the following measures: Follow-Up After High-Intensity Care for Substance Use Disorder, Identification of Alcohol and Other Drug Services, Initiation and Engagement of Alcohol and Other Drug Abuse or Dependence Treatment.

9.15.2021 Guidelines for Calculations and Sampling: Hybrid Method How should the eligible population be reported for hybrid measures if there are optional or required exclusions?

The eligible population for hybrid measures should be reported before the optional exclusions and after the required exclusions for all three hybrid method approaches (refer to Appendix 4 in HEDIS Volume 2). For example, if the eligible population is 100 members and 10 members met optional exclusion criteria, then the reported eligible population value must still be 100.

9.15.2021 Acute Hospital Utilization, Emergency Department Utilization and Hospitalization for Potentially Preventable Complications When should rounding occur for variance calculations?

The variance should not be rounded until the final step in the calculation. The final variance calculation for reporting should be rounded to four decimal places using the .5 rule. For example, the PPD and PUCD values are truncated to 10 decimal places, multiplied together at the member level and summed across members for the total. Round the total sum to four decimal places.

9.15.2021 Guidelines for Calculations and Sampling: Hybrid Measures How should exclusions be applied when found during an administrative data refresh for hybrid measures?

Per General Guideline 32, there are two ways to apply exclusions after samples have been pulled and chart review has begun. Because the sample must be reproducible, the members remain in the eligible population but are removed from the sample and reflected in the denominator. Organizations should indicate the exclusions by reporting them as valid data errors. When the population is larger than the MRSS, replace those members with members from the oversample.

Remember that the denominator is used to calculate and report the measure. All exclusions and replacements are reflected in the denominator calculation. The following are examples:

Example 1:
Eligible population = 300
MRSS = 300
Oversample Rate = 0%
Oversample Records Number = 0
Number of valid data errors = 3
Oversample Records Added = 0
Denominator = 297

Example 2:
Eligible population = 5,800
MRSS = 411
Oversample Rate = 5%
Oversample Record Number = 21
Number of valid data errors = 11
Oversample Records Added = 11
Denominator = 411

9.15.2021 Well-Child Visits in the First 30 Months of Life (W30) Does a well child visit with an OB/GYN meet criteria for the W30 measure?

Yes, if the OB/GYN is considered to be a PCP by the health plan (i.e., offers primary care medical services). Refer to Appendix 3 of HEDIS Measurement Year 2022 for the definition of “PCP.”
