About the CGS OEC Center
CGS offers many online education courses on popular topics. These presentations range from 15 to 45 minutes and provide a valuable overview of both policy-specific topics like ostomy supplies, and general topics like Advance Beneficiary Notice of Non-coverage. There's also a complete series called "Welcome to Medicare" that takes you step-by-step through the Medicare process. These are great training tools for new staff as well as opportunities for veteran suppliers to brush up on their knowledge or learn about a new policy. Best of all, these online education courses are available whenever you find it most convenient; you can even pause the course and come back later. It's another way we strive to provide information that will help your company thrive.
