Medicare Advantage plans are an alternative to Original Medicare, offered by Medicare-approved private insurance companies. These plans include Medicare Part A (hospital) and Part B (medical), and most also include Part D (prescription drug coverage). Many plans offer added benefits like routine dental, vision, hearing, and fitness programs.
Medicare Eligibility
To enroll in a Medicare Advantage plan, you must first sign up for Original Medicare (Parts A and B). Most people become eligible for Medicare enrollment at age 65, but some qualify earlier due to disability or conditions like ALS or ESRD. The article outlines key enrollment periods—Initial, General, and Special Enrollment—and highlights potential penalties for late enrollment or not qualifying for premium-free coverage.

Other Medicare Plan Options to Help with Out-of-Pocket Costs
Medicare Supplement plans, or Medigap, are standardized policies sold by private insurers to cover out-of-pocket costs from Original Medicare, such as deductibles, copayments, and coinsurance.
- You must be enrolled in Medicare Parts A and B to purchase a plan.
- The best time to enroll is during the six-month Medigap Open Enrollment Period, which starts when you enroll in Medicare Part B. During this time, coverage is guaranteed regardless of health. After that, you may need to pass medical underwriting.
- Medigap plans don’t cover prescription drugs, so you’ll need a separate Part D plan.
- There are 10 standardized plans, with Plans F, G, and N being the most popular. Medicare Supplement Plan G had the highest enrollment in 2023, and Plans G and N are the fastest-growing.
- Due to Medicare changes in 2020, Plan F is no longer available to newly eligible beneficiaries. Premiums vary by plan and location, but all offer predictable costs, no referrals, and nationwide
