Thank you for your inquiry on CMS2v14: Preventive Care and Screening: Screening for Depression and Follow-Up Plan. The measure considers any qualifying encounter during the measurement period for consideration in the denominator. However, the qualifying encounter must be documented using a code included in "Encounter to Screen for Depression” (2.16.840.1.113883.3.600.1916), "Physical Therapy Evaluation" (2.16.840.1.113883.3.526.3.1022), or "Telephone Visits" (2.16.840.1.113883.3.464.1003.101.12.1080) value set. The eCQMs rely on the associated codes listed in the values on Value Set Authority Center (VSAC) to drive the measurement results. If one of the codes in the qualifying encounter value sets is documented, that meets the definition of a qualifying (eligible) encounter. Clinically equivalent services may be mapped to the codes used in a measure's value sets to satisfy the denominator requirement.   These value sets are located on The National Library of Medicine's Value Set Authority Center (VSAC), https://vsac.nlm.nih.gov/ . The VSAC provides downloadable access to all official versions of value set content contained in the eCQM specifications. The value sets are lists of unique coded identifiers with names (called descriptors) for groupings of clinical and administrative concepts selected from standard vocabularies.
