The 2022-2023 MS Medicaid RSV season will begin soon. Prior authorization units are authorized to begin accepting Synagis® PA requests for consideration beginning October 11, 2022, for dates of service starting November 1, 2022. Synagis® will NOT be authorized for typical seasonal administration prior to the season start date. However, due to the atypical nature of RSV prevalence during 2022, there have been some case-by-case PA approvals during recent months. The off-season guidance to consider requests case-by-case will remain in place prior to November 1st.
