Gerard J. Criner, MD, FACP, FACCP, Chair and Professor of Thoracic Medicine and Surgery at the Lewis Katz School of Medicine at Temple University and Director of the Temple Lung Center, provided perspective for a Medscape article on the decision by the Centers for Medicare & Medicaid Services (CMS) to cover respiratory assist devices (RADs) and home mechanical ventilators for patients who meet certain criteria specified in the decision memo. The decision was based in part on the latest version of a document created by the COPD Technical Expert Panel working group. The report was published online in Chest in 2021, and Dr. Criner was a co-author.
