Hi Tracey, thank you for reaching out to us with your question. Traditional Medicare is Medicare Part A and B, which only covers about 80% of billed costs. A Medigap plan, like the plan G you mentioned, would typically pick up the other 20%. To summarize, people choosing traditional Medicare will typically also purchase a Medigap plan to cover most of their medical costs.
