Can you have both employer insurance and Medicare?

The number of employees your company has will be a good telltale indicator for this. But, you must always speak with your company’s benefits administrator to get confirmation before acting. The general rule of thumb previously was if your company had less than 20 employees, the two coverages could work in conjunction with each other, one acting as your primary insurance provider and the other operating as the secondary coverage provider paying for what might be billable under that specific policy.
