Short answer: Your enrollment window is 7 months around your 65th birthday — enroll in the first 3 months so coverage starts on time and you avoid lifelong penalties. Below: the Tennessee-specific piece most guides skip.
Turning 65 in Tennessee means the same federal deadline as everywhere — plus state specifics worth knowing before you choose. Here's the plain-English version.
Your 7-month Initial Enrollment Period
The window: 3 months before your birthday month, the month itself, and 3 months after. Enroll early for coverage that starts the first of your birthday month. Miss it without other creditable coverage and the Part B penalty (10% per full year delayed, for life) and the Part D drug-coverage penalty apply.
Tennessee: metro depth, rural caution
Tennessee's Advantage market is strong in Nashville, Memphis, Knoxville, and Chattanooga — but plan counts and networks thin out fast in rural counties, where hospital access itself has tightened. If you're rural, confirm your hospital and specialists are genuinely in-network before choosing Advantage; Original Medicare + a Supplement often serves rural Tennesseans better.
