Medicare Supplement help in St. Mary's County, Maryland
Original Medicare pays a large share of your care, but it leaves deductibles, coinsurance and copays behind. A Medicare Supplement, also called Medigap, can pay part of that gap. Here is how it works for people who live and get care here, from Leonardtown and California to Lexington Park and Charlotte Hall.
The first question
What does a Supplement actually pay for?
Start with what Original Medicare leaves to you. In 2026, Part A has a deductible of $1,736 for each inpatient hospital benefit period. Part B has a yearly deductible of $283, and after that you usually owe 20% of the Medicare-approved amount for covered services. The standard Part B premium is $202.90 a month in 2026, and it is higher for people with higher incomes.
A Medicare Supplement is private insurance that works alongside Original Medicare. Medicare pays its share first. Your Supplement then pays some or all of what is left, depending on the plan letter you choose. The letters, from A through N, are standardized, so a Plan G from one company has the same benefits as a Plan G from another. The price is what differs.
Two practical points are worth knowing early. A Supplement covers one person, so spouses each need their own policy. And you must keep paying your Part B premium on top of the Supplement premium, because Medicare does not pay Supplement premiums.
Where you live matters
Why this question comes up in St. Mary's County
St. Mary's County was established in 1637 and sits on a peninsula with the Patuxent River, the Chesapeake Bay, the Potomac River and the Wicomico River around it. More than half of its 764 square miles is water. The 2020 census counted 113,777 residents, and about 13.5% of them were 65 or older. Leonardtown is the county seat, and California is the largest community.
The county is also home to Naval Air Station Patuxent River and a sizable defense contractor presence, along with St. Mary's College of Maryland. That mix means many households here carry federal, military or contractor retirement benefits into Medicare, and some have retiree coverage that interacts with it. We are not affiliated with the base or with any military program, and we do not represent TRICARE. If you have TRICARE For Life or retiree coverage, talk with us before you buy a Supplement, because it may or may not add value for you.
Getting care often means a drive. MedStar St. Mary's Hospital is in Leonardtown, and anyone who sees a specialist in another county has a longer trip. Because a standard Supplement has no provider network, it follows you to any doctor or hospital that accepts Medicare. That flexibility is a real reason people choose one. Our local care page lists the hospital and urgent care locations we reviewed.
Plan letters in plain words
The three plans people ask about most
- Plan G
- Covers nearly everything Original Medicare leaves behind, except the yearly Part B deductible ($283 in 2026). After you pay that deductible, you generally owe nothing more for Medicare-covered services for the rest of the year.
- Plan N
- Usually has a lower premium than Plan G. It covers Part B coinsurance but asks for a copay of up to $20 for some office visits and up to $50 for emergency room visits when you are not admitted. It does not cover Part B excess charges.
- High Deductible Plan G
- Has benefits like Plan G once you pay a deductible, which is $2,950 in 2026. The premium is typically lower, and you take on more cost before the plan pays.
These are descriptions, not recommendations. The right fit depends on your health, your budget and how you like to handle costs. We set the three side by side on our Plan G, Plan N and High Deductible G comparison.
Timing
The enrollment window is the part people miss
In Maryland, the most important window is the six-month Medigap open enrollment period that begins when you are 65 or older and enrolled in Part B. During those six months, you can buy any Supplement the companies sell in your area without answering health questions. After that window, carriers may use medical underwriting, which means they can ask about your health and may decline or charge more. Maryland does not have a yearly open enrollment for Supplements.
That is why we encourage clever 64-year-olds to start looking a few months before their birthday month. Details, including what changes if you are still working, are on our enrollment window page.

Questions we hear
Quick answers
Do I need a provider network to use a Medicare Supplement?
Original Medicare with a Supplement has no provider network, so you can see any doctor or hospital that accepts Medicare. Plans sold as Medicare SELECT are an exception and may ask you to use certain providers. Network participation varies by plan. Call us to check whether a facility is in yours.
Does a Medicare Supplement cover prescription drugs?
No. A Supplement helps with Part A and Part B costs. Drug coverage comes from a separate Part D plan, which we explain on our Supplement and Part D page.
Can my spouse and I share one Supplement policy?
No. A Supplement policy covers one person, so each spouse or partner needs a separate policy.
What does a Medicare Supplement cost?
The monthly premium depends on the insurance company, the plan letter and your personal details, and it changes over time. We compare several companies for you at no cost. Rates can change without notice.
