You can enroll in supplemental plans directly in BenTek. To begin click on the pen and paper icon to the left of the plan's name (indicated by the red arrow below).
Depending on the requirements for the plan, you may be asked several enrollment questions. You will then be shown a list of enrollment options to select from, as well as any dependents that may be covered. Use the radio buttons to select the options you want and click Next. You can also click Back if you need to go back to the previous step or cancel.
You may be asked to Agree to any terms and click the Submit button to finalize your selection. You will then be brought back to the original display, which will now show your updated enrollment, as demonstrated in the image below.
