FAQs
How much does Medigap Plan G cost in Tennessee?
Plan G premiums in Tennessee run around $133 a month for most new enrollees, though your exact rate depends on your age, sex, tobacco use and the insurer you choose.
What happens if I apply for Medigap in Tennessee after my enrollment window closes?
Outside the 6 month Open Enrollment period, insurers in Tennessee can ask health questions and use medical underwriting, which can mean a higher premium or a denied application.
What drives the price difference in Tennessee
Tennessee follows the standard federal Medigap framework, so the coverage inside every Plan G is identical across all carriers. The benefits do not change. What does change is the premium, and the spread between the lowest and highest quotes for the same plan can be significant. Carriers are allowed to use attained-age pricing, which means your premium can rise as you get older, or issue-age pricing, which locks in your rate tier at the age you first enroll. It is worth asking which method a carrier uses before you sign.

Things to Know Before You Enroll in Tennessee
Federal law gives you a 6-month Open Enrollment Period that starts when you are both 65 or older and enrolled in Part B. During that window insurers cannot turn you down or charge you more based on your health history. Once the window closes, they can. The open enrollment calculator shows you exactly when your window opens and closes.
