Thank you for your inquiry for CMS147v10, Preventive Care and Screening: Influenza Immunization. Please refer to the statement below from the 2021 eCQM Telehealth Guidance. eCQMs listed in Table 1 in the document, including CMS147v10, contain Medicare telehealth-eligible codes found in encounter value sets, which can be used for in-person or telehealth encounters. For example, CPT code 99347 found in the "Encounter-Influenza" value set (2.16.840.1.113883.3.526.3.1252) is appropriate to use. "For the 2021 performance period, the majority of the eligible professional/eligible clinician eCQMs include Current Procedural Terminology (CPT) and Healthcare Common Procedure Coding System (HCPCS) encounter codes that are appropriate to use for either in-person or telehealth encounters based on the list of services payable under the Medicare Physician Fee Schedule (see https://www.cms.gov/Medicare/Medicare-General-Information/Telehealth/Telehealth-Codes).1 The current eCQM logic and value sets do not differentiate between in-person encounters or telehealth encounters when these “telehealth-eligible” CPT and HCPCS codes are used. Unless otherwise stated in this document, encounters identified with CMS telehealth-eligible codes are eligible for inclusion within the eligible professional/eligible clinician eCQMs for the 2021 performance period, whether the encounter was provided in person or via telehealth." 1 The Centers for Medicare & Medicaid Services may update this Medicare Telehealth Service list. The information provided in this guidance document is based on an analysis done using the April 30, 2020, publication titled, “Telehealth Services for PHE for the COVID-19 pandemic effective March 1 2020-updated April 30 2020.xlsx.” Reference: Telehealth Guidance for Electronic Clinical Quality Measures (eCQMs) for Eligible Professional/Eligible Clinician 2021 Quality Reporting. https://ecqi.healthit.gov/sites/default/files/2021-eCQM-Telehealth-Guidance-Document-With-QRDA-Update-508.pdf
