Medicare, explained in plain language
Understand your choices and compare plans from the carriers we represent in your area.

Medicare is the federal health insurance program for people age 65 and older and for some younger people with disabilities. It has several parts, and you can add coverage to fill gaps. Bridgemont Life is an independent insurance agency. We help you understand your options and compare plans.
Your Medicare choices
You can keep Original Medicare and add other coverage, or you can join a Medicare Advantage plan. Here is how each piece works.
Original Medicare (Part A and Part B)
Original Medicare is run by the federal government. Part A helps cover hospital stays. Part B helps cover doctor visits, outpatient care and preventive services.
- You can see any doctor or hospital in the country that accepts Medicare.
- You pay deductibles, copayments or coinsurance, and a monthly Part B premium.
- There is no yearly limit on what you pay out of pocket.
- It does not cover most prescription drugs or routine dental, vision and hearing care.
Medicare Advantage (Part C)
Medicare Advantage plans are offered by private insurance companies that contract with Medicare. They provide your Part A and Part B coverage. Most also include prescription drug coverage, and many add benefits such as dental, vision and hearing.
- Most plans use a network of doctors and hospitals. Costs can be higher outside the network, and some plans do not cover out-of-network care.
- Plans have a yearly limit on what you pay out of pocket for covered services.
- You still pay your Part B premium, and some plans charge a monthly premium too.
- Plans, costs and benefits vary by county and can change each year.
Medicare Supplement (Medigap)
Medicare Supplement plans are sold by private insurance companies. They help pay costs that Original Medicare leaves, such as deductibles, copayments and coinsurance.
- They work only with Original Medicare. You cannot use a Medigap plan with a Medicare Advantage plan.
- Plans are standardized and labeled with letters, such as Plan G or Plan N. In most states, the same letter means the same basic benefits no matter which company sells it. Prices differ by company.
- You pay a monthly Medigap premium on top of your Part B premium.
- Medigap does not include prescription drug coverage. You add a separate Part D plan.
- The key time to buy is the Medigap Open Enrollment Period. It lasts six months, starting the month you are 65 or older and have Part B. During this time, companies cannot turn you down or charge you more because of your health. After it ends, they may.
Prescription drug plans (Part D)
Part D plans are sold by private insurance companies. You can add one to Original Medicare or to a Medigap plan. Many Medicare Advantage plans already include drug coverage.
- Each plan has a list of covered drugs and a network of pharmacies. Check your medicines before you join.
- Plans differ in premiums, deductibles and copays.
- If you go 63 days or more in a row without drug coverage that counts as creditable after you first qualify, you may pay a late penalty.

Medicare has set windows for joining and changing coverage. Missing one can mean waiting or paying more. Here are the main ones.

It starts three months before the month you turn 65 and ends three months after that month. | Sign up for Part A and Part B. Join a Medicare Advantage plan or a Part D plan.

Turning 65 checklist
Start about three months before your birthday month. Use this list to stay on track.
- Mark your dates. Your Initial Enrollment Period starts three months before the month you turn 65.
- Check Social Security. If you already get Social Security benefits, you are usually signed up for Part A and Part B automatically. If you do not, you sign up through Social Security.
- Review coverage from work. If you or your spouse still work, ask your benefits office how your plan works with Medicare before you delay Part B.
- Gather your information. List your doctors, your medicines and the pharmacies you use.
- Pick a path. Decide between Original Medicare with a Medigap plan and a Part D plan, or a Medicare Advantage plan. We can talk it through with you.
- Compare and enroll. Compare premiums, deductibles, copays, yearly out-of-pocket limits, networks and drug lists. Then sign up during your window.
- Review every fall. Plans change each year. Read your plan's yearly notice and review your options during the Annual Enrollment Period.
