CMS Announces Historic Changes to Physician Self-Referral Regulations Today, the Centers for Medicare & Medicaid Services (CMS) finalized changes to outdated federal regulations that have burdened health care providers with added administrative costs and impeded the health care system’s move toward value-based reimbursement.
