This represents the first enforcement action under the Rule since it went into effect on January 1, 2021. In a December 2020 Medicare Learning Network update, CMS stated that it planned to audit a sample of hospitals for compliance with the Rule staring in January and that it would also investigate any complaints it received regarding hospitals not in full compliance with the Rule. CMS previously indicated that enforcement of the Rule would generally occur in the following order: 1) written warning; 2) corrective action plan; and 3) civil monetary penalty.
