Instructions

This measure is to be submitted a minimum of once per performance period for all patients with a diagnosis of schizophrenia or schizoaffective disorder seen during the performance period. This measure may be submitted by eligible clinicians who perform the quality actions described in the measure for the primary management of patients with schizophrenia or schizoaffective disorder based on the services provided and the measure-specific denominator coding.

Numerator

Individuals in the denominator who have a Proportion of Days Covered (PDC) of at least 0.8 for antipsychotic medications

NUMERATOR NOTE: The PDC is calculated as follows:

PDC NUMERATOR:

The PDC numerator is the sum of the days covered by the days’ supply of all antipsychotic prescriptions. The period covered by the PDC starts on the day the first prescription is filled (index date) and lasts through the end of the measurement period, or death, whichever comes first. For prescriptions with a days’ supply that extends beyond the end of the measurement period, count only the days for which the drug was available to the individual during the measurement period. If there are prescriptions for the same drug (generic name) on the same date of service, keep the prescription with the largest days’ supply. If prescriptions for the same drug (generic name) overlap, then adjust the prescription start date to be the day after the previous fill has ended.

PDC DENOMINATOR: The PDC denominator is the number of days from the first prescription date through the end of the measurement period, or death date, whichever comes first

Numerator Options:

Performance Met: Individual had a PDC of 0.8 or greater (G9512)

OR

Performance Not Met: Individual did not have a PDC of 0.8 or greater (G9513)
