CMSThe Centers for Medicare and Medicaid Services (CMS) is ramping up efforts to limit patients’ access to pain medication without giving affected parties sufficient notice or opportunity for comment.  Since the start of 2017, CMS has released three separate guidance documents on how insurers and payers should impose new limits on the use of opioids.  While opioid abuse undoubtedly presents a serious public health issue, CMS should take steps to foster transparency and avoid harming patients and providers alike by offering them a meaningful opportunity to participate in the development of policies that could limit pain management.  CMS also must do more to ensure that it adheres to statutes requiring complete openness whenever it solicits advice from advisory committees that include members who are not federal government employees.
