On May 4, 2011, CMS published a proposed rule that would require certain Medicare and Medicaid providers and suppliers to offer all patients an annual influenza vaccination, unless medically contraindicated or unless the patient (or patient’s representative or surrogate) declines vaccination. The requirement would apply to the following entities: hospitals (all types that participate in Medicare); CAHs; rural health clinics; Federally Qualified Health Centers, and end-stage renal disease facilities. These providers and suppliers have been proposed because: (1) in each setting, the patient presents before health care providers with staff licensed to provide vaccination at the time and location of the encounter; and (2) all have ready access to equipment and storage appropriate for handling, controlling, and administering vaccines. The proposed rule also would require the specified providers and suppliers to develop policies and procedures that would allow them to offer vaccinations for pandemic influenza, in case of a future pandemic influenza event for which a vaccine may be developed. CMS will accept comments on the proposal until July 5, 2011. CMS expects to adopt a final rule in the early fall of 2011 that would be in effect during the 2011-2012 influenza season.
