Medicare Advantage

Before you compare counties, read this Vicksburg guide

Vicksburg sits in Warren County, and as you look ahead to 2027 the number of Medicare Advantage options in the area is worth putting in context. Plan availability is set county by county, so what a neighbor in the next county over sees on Medicare.gov may look different from what you see in Vicksburg. This snapshot walks through what the local count means, how to read it, and where to look for personalized help.

What "plan availability" really means

When CMS publishes the Medicare Advantage and Part D landscape each fall, the counts are tied to counties, not cities. Vicksburg is in Warren County, where 50 Medicare Advantage plans were available for 2026, offered by 7 carriers with Medicare Advantage Prescription Drug (MA-PD) contracts serving the area. For the 2027 lineup, check each plan's ANOC and Medicare.gov's Plan Finder.

If you cross the county line — say into a neighboring Mississippi or Louisiana county — the list on Medicare.gov can look different. Some plans serve a single county. Others cover a wider footprint. That is why two people who live 15 miles apart can be shopping from two different menus.

The Warren County snapshot heading into 2027

Here is the area-level picture, straight from CMS data for 2026:

• Medicare Advantage plans available in Warren County: 50
• Stand-alone Part D plans available in the area: 0 (Note: stand-alone Part D plans are typically sold at the state/region level; check Medicare.gov for the plans available to Mississippi residents.)
• Carriers offering MA-PD in the area: 7
• Population age 65 and older: about 8,155

A count of 50 Medicare Advantage plans is a wide field. It does not mean 50 plans will fit any one person's doctors, prescriptions, or budget — it just means there is room to compare.

How to compare across nearby areas

If you have family or a second home in a nearby county, or you are thinking about a move, do not assume the plan you have travels with you. To compare:

1. Go to Medicare.gov's Plan Finder and enter each ZIP code separately. 2. Note how the plan counts and carrier lists change from county to county. 3. Look at each plan's provider network and pharmacy list — those are what actually decide whether a plan works for you.

Counts alone are just the starting point.

What is new for 2027 at the program level

A few Medicare-wide rules affect every county, including Warren:

• The Part D annual out-of-pocket cap on covered drugs is $2,100 in 2026 and $2,400 in 2027.
• The Part D deductible cannot be higher than $615.
• The old "donut hole" coverage gap is gone; Part D now has three phases.
• The Medicare Prescription Payment Plan lets you spread drug costs across the year in monthly payments if you choose.
• IRMAA (higher premium surcharges) begins above $109,000 in income for a single filer in 2026.

Dates to keep in mind

• Annual Enrollment Period: October 15 – December 7, 2026. This is when most people compare and switch Medicare Advantage or Part D plans for 2027.
• Medicare Advantage Open Enrollment Period: January 1 – March 31. If you are already in a Medicare Advantage plan, you get one chance during this window to switch to another Medicare Advantage plan or return to Original Medicare.
