Guide to Medicare Part C: Medicare Advantage Plans
Considering a Medicare Part C plan? Our guide will explain what Medicare Part C is, how these plans work, what they cover, and the pros and cons compared to Original Medicare.
If you have recently begun exploring your Medicare coverage options, you are likely already familiar with Medicare Part A and Part B. These two components form Original Medicare, covering inpatient services (Part A) and outpatient services (Part B). While these plans cover many medical expenses, they also leave gaps that beneficiaries often choose to fill with a Supplemental Plan or a Medicare Part C plan.
This guide will provide a detailed explanation of what Medicare Part C is, what it covers, and its costs, helping you decide whether it is the right Medicare plan for you.
What is Medicare Part C?
Medicare Part C, commonly referred to as Medicare Advantage, is an alternative to Original Medicare (Parts A and B). Introduced in 2003, Medicare Advantage plans offer another option besides supplemental plans. When you enroll in a Medicare Part C plan, you transition out of the Original Medicare system and into a private network established by your insurance provider.
Since this private network replaces Original Medicare coverage, Medicare Advantage plans are often called replacement plans. With a Medicare Part C plan, a private health insurance company becomes your primary coverage provider, consolidating all services into a single card instead of multiple ones.
Why Do I Need Medicare Part C?
Medicare Part A and Part B cover preventive care, medically necessary services, and skilled nursing facility stays. They also include hospital insurance for inpatient care. While this might seem extensive, these plans do not cover many essential medical expenses.
For example, outside of an annual wellness exam, any additional doctor’s visits throughout the year require out-of-pocket payments. Elective procedures are typically not covered, potentially leading to substantial medical bills.
Unlike Original Medicare, Medicare Advantage plans can help cover both preventive and elective health services, offering enhanced financial protection and additional benefits.
What Does Medicare Part C Cover?
A key advantage of Medicare Part C is that it functions as a comprehensive plan covering services that Medicare Part A and Part B do not. These additional services often include:
Vision care
Dental services
Hearing aids
Prescription medications
Many Medicare Advantage plans feature low monthly premiums, and some even have $0 premiums. However, it is important to note that Medicare Advantage operates on a pay-as-you-go model, meaning costs are based on service usage.

How Does Medicare Advantage Part C Work?
Although Medicare Advantage plans are often called replacement plans, enrollees must still be enrolled in Medicare Part A and Part B. Additionally, beneficiaries are responsible for paying the monthly Part B premium ($202.90 for most individuals, though higher-income earners may pay more based on their Modified Adjusted Gross Income (MAGI)).
Medicare Part C providers establish HMO or PPO networks to offer medical services to their members. Whether the plan is an HMO or PPO, Medicare Advantage follows a pay-as-you-go system, requiring enrollees to make copayments for various services.
Examples of Copayments in Medicare Advantage Part C Plans:
Hospital Visit: $350 per day
Outpatient Surgery: $250 copay
CT Scan or MRI: $200 copay
Specialist Appointment: $50 copay
Additionally, enrollees may face deductibles and coinsurance costs for specific services. Some Medicare Part C plans require pre-authorization for certain treatments, meaning the insurance company must approve the service before coverage applies.
