Using Medicare for the 1st time - But my doc says I'm still on Group Insurance.  But I'm NOT!

Many times when an enroller at the Social Security office enters in a new application for Part B, they forget to push the button that says Medicare Primary - No longer on Group Insurance.  This happens when a person is leaving Group Employer coverage.  When the doctor runs the bill through Medicare, Medicare tells them that the Group policy is primary.
