What Medicare Advantage actually is

Medicare Advantage, often called Part C, is a private plan that delivers your Part A and Part B benefits through a single plan rather than through Original Medicare directly. Most Medicare Advantage plans also build in prescription drug coverage, so one plan handles hospital, medical and pharmacy. You stay in the Medicare program the whole time, and you keep paying your Part B premium — $202.90 a month in 2026, and more for higher earners once modified adjusted gross income passes $109,000 for one person or $218,000 for a couple filing jointly, where the first bracket brings the Part B total to $284.10 a month.

Two structural differences separate it from Original Medicare paired with a Medicare Supplement. First, a Medicare Advantage plan has an annual out-of-pocket maximum, which Original Medicare on its own does not. Second, it works through a provider network, which a Medigap policy does not. Those two facts drive almost every real decision people make here, and neither path is better in the abstract. The right one depends on your doctors, your medications and how you want your year to work.

In Nashville, the network question is the whole question

This is where a Tennessee page stops being a formality. Nashville is served widely by three large health systems — Vanderbilt, Ascension Saint Thomas and TriStar — and they overlap across the city rather than dividing it into territories. A household here can easily be using two of the three without ever having thought of it as a choice: a primary care doctor in one system, a cardiologist or an orthopedic surgeon in another, and the nearest hospital belonging to a third.

That is exactly the arrangement a network can interrupt. When people say a Medicare Advantage plan “covers Nashville,” what matters is not the city — it is whether your specific doctors, at their specific locations, are in that plan's network this year. Specialists deserve the same check as primary care, and so do the facilities where procedures actually happen. Networks are also reviewed annually, so a plan that fit your household in one year can shift under you in the next. We check each provider by name rather than by system, and we check again every fall.

Where you live decides what is on the menu

Medicare Advantage and Part D availability can vary by county and ZIP code. This is the most practical fact on this page. The plans offered in Davidson County are not automatically the plans offered in Williamson, Sumner, Wilson or Rutherford. Someone in Franklin, Brentwood, Spring Hill or Nolensville may see a different list than someone in Gallatin or Hendersonville, and different again from Lebanon, Mount Juliet, Murfreesboro, Smyrna or La Vergne — even though they all drive into Nashville for the same specialist.

It follows that a recommendation from a neighbour, a brother-in-law or a television advertisement is not evidence about your options. It is evidence about theirs. Our Medicare page for Nashville covers how we work across these counties.

What these plans include, and what we will not claim

Medicare Advantage plans commonly bundle extras beyond Parts A and B. What any particular plan includes, what it costs and whether it is offered where you live varies from plan to plan and year to year, so we do not describe benefits in general terms and we never name a carrier on a page like this. We look up the specific plans available in your county and read the actual terms with you. What we can say about the structure is that the out-of-pocket maximum is real protection, that copays replace the open-ended 20% coinsurance of Original Medicare, and that referral and prior-authorization rules differ by plan and are worth understanding before you need them rather than after.

Prescription coverage is usually built in — check anyway

Most Medicare Advantage plans include drug coverage, which is convenient but does not make the formulary less important. Each plan still has its own covered-drug list, its own tiers and its own pharmacy network, and the same medication can cost very differently from one plan to the next. In 2026 no Part D deductible may exceed $615 and your spending on covered drugs is capped at $2,100; in 2027 those figures are $700 and $2,400. Our guide to how Medicare Part D works in Tennessee explains what to check. If a plan does not include drug coverage and you have none elsewhere, a lasting surcharge can follow — see the Medicare late enrollment penalty.

Tennessee has six dual-eligible plans, integrated with TennCare

Some Medicare Advantage plans are built specifically for people who have both Medicare and Medicaid. These are called dual eligible special needs plans, or D-SNPs. On the 2026 CMS list, Tennessee has six, and all six are fully integrated with TennCare — meaning the Medicare side and the state side are coordinated through one plan rather than operating as two separate programs that leave the member to referee between them. For a household managing both, that integration is a genuine practical difference, and it is not something every state offers.

To be clear about our role: The Jordan Insurance Agency helps on the Medicare side. We do not sell or advise on TennCare and we are not a TennCare resource. Whether someone has both forms of coverage is something that gets verified, never assumed, and we will not tell you across a desk that you do or do not fit a program.

Changing your mind later

You are not locked in forever, but the doors are not all open at the same time either. The Annual Enrollment Period, October 15 to December 7, lets anyone with Medicare switch plans, with changes taking effect January 1. A separate window, January 1 to March 31, lets people already in a Medicare Advantage plan make one change. Moving between counties can open a window of its own, which matters here given how much availability shifts across Middle Tennessee. Our guide to when you can enroll in Medicare in Tennessee lays the windows out in order. One caution worth hearing early: moving from Medicare Advantage to a Medigap policy later can involve health questions, which is not true of moving the other direction. If you are still working and weighing all of this, start with how Medicare works with employer coverage in Tennessee.

How The Jordan Insurance Agency helps

We pull the plans actually offered in your county, check every doctor you see by name and location, run your medication list against each formulary, and show you what a normal year and a bad year would each cost. Then we do it again the following fall, because networks and drug lists are rewritten every year whether or not anything changed on your end.

The Jordan Insurance Agency is an independent, licensed insurance agency with a Tennessee office at 159 4th Avenue N, Suite 100, Nashville, TN 37219. You can reach us at (615) 558-6082, Monday through Friday, 8:00 AM to 4:00 PM Central. Because we are independent we represent multiple carriers rather than one, so we can lay your real options side by side instead of steering you toward a single company. A consultation with a licensed agent is free, and your premium is the same whether you enroll on your own or with our help.
