Thank you for your inquiry regarding CMS2v11: Preventive Care and Screening: Screening for Depression and Follow-Up Plan. Per the definition section of the measure header, the measure requires use of a normalized and validated depression screening tool developed for the patient population in which it is being utilized. While a list of example depression screening tools is provided, this list is not meant to be exhaustive. Therefore, the PHQ-8 is an appropriate standardized depression screening tool that meets numerator requirements.
