Ametros Regulatory Council

Our Mission

The mission of the Regulatory Advisory Council is to continually be aware and informed on regulatory changes and best practices that could impact our clients, partners and members. Given the important interaction that professional administration, workers’ compensation, and Medicare Secondary Payer industries have with healthcare, data security, banking, insurance and other regulatory sectors, Ametros believes that there should be considerable oversight and resources for our company as well as the broader industry.

The Council will monitor and analyze proposed changes and advancements to the Medicare Secondary Payer statute, as well as worker’s compensation and healthcare regulations. It will also examine consumer protection, data security, privacy compliance, patient advocacy, and broader personal injury issues and regulations.
