Important Tip for Searching Medicare Advantage Plan Eligibility Information in myCGS

Using the Eligibility search in myCGS to find current date Medicare Advantage Plan (MAP) information requires adjusting the date of service from the default setting. Carefully read the instructions below.

The Beneficiary Eligibility Request in myCGS defaults the date of service field to today's date, but you can change the field by entering a specific date.

Beneficiary Eligibility Request

myCGS searches for eligibility information within a 16-month span—one year prior to and four months after—of the date of service entered. Since the date of service field defaults to today's date, any known future information (within the four-month future span from today's date) will display in the default search.

It's important to note that the MAP information in myCGS is based on the four-month future date, rather than the current date (or date entered in the search). For instance, if you enter 2/15/2023 as the date of service in your eligibility search, the MAP information displayed in myCGS will be for 6/15/2023. Therefore, if you need to find MAP information that is current for today, you need to subtract four months from today's date when entering the date of service. (If today is 2/15/2023, then you would search for date of service 10/15/2022).

The following chart illustrates the date of service and MAP information displayed in myCGS.
