Permanent Rulemaking Hearing - March 17, 2021

The Office of Naturopathic Doctor Registration will hold a VIRTUAL Permanent Rulemaking Hearing to allow stakeholders a final opportunity to provide feedback before the Director considers adopting the proposed revisions to Rule 1.19, as required by the Office of Legislative Legal Services (OLLS). The proposed rule revisions correct language that was recently adopted, that conflict with portions of the statutes in Colorado Senate Bill 20-102 (Concerning required disclosures to patients regarding formal actions based on sexual misconduct).
