The Centers for Medicare & Medicaid Services (CMS) released updated interpretive guidance on its Omnibus COVID-19 Health Care Staff Vaccination Interim Final Rule for states affected by yesterday’s Supreme Court’s decision on the rule. The guidance does not apply to Texas, where the Interim Final Rule is still subject to a preliminary injunction in a separate legal action that was not before the Supreme Court. Under the guidance, the first dose compliance date for those states is Feb. 14, 2022, with full compliance expected from providers by March 15, 2022. For states not impacted by the Supreme Court decision, the previously announced compliance dates of Jan. 28 and Feb. 27 remain in effect. For both groups, the underlying interpretive guidance released on Dec. 28 applies and all members can still refer to the previously released Frequently Asked Questions for additional information.
