Colorado House Bill 1300 was introduced, which could enact major changes to rules on medical treatment and physician selection in workers' compensation. Highlights of the bill include:

• Shifting the burden of proof to insurers in medical treatment disputes
• Mandating adherence to utilization standards. Non-compliance may result in authorized treatment
• Requiring employers to notify workers of their right to select a doctor within 7 business days of an injury
• Giving injured workers 7 days to choose a doctor from an approved list before the employer/insurer selects one
• Allowing one doctor change within 120 days or before reaching maximum medical improvement
