Medicare Part C (Medicare Advantage)

Medicare Part C, also known as Medicare Advantage, is an all-in-one private alternative to Original Medicare. These plans bundle Part A, Part B, and usually Part D into a single package. While provided by private insurers, they are strictly regulated and approved by Medicare.

Key Aspects

  • Bundled Coverage: Combines hospital, medical, and often prescription drug coverage.
  • Extra Benefits: Most plans include services not covered by Original Medicare, such as routine dental, vision, hearing, and fitness memberships.
  • Spending Limit: Unlike Original Medicare, these plans have a mandatory Maximum Out-of-Pocket (MOOP) limit. Once reached, the plan pays 100% of covered medical services for the rest of the year.
  • Network-Based: Beneficiaries typically use a specific network of doctors and hospitals (HMO or PPO).
  • To enroll in Part C, an individual must already have Medicare Part A and Part B.

Common Plan Types

  • HMO (Health Maintenance Organization): Usually requires using in-network providers and obtaining referrals for specialists.
  • PPO (Preferred Provider Organization): Offers more flexibility to see out-of-network providers at a higher cost; referrals are typically not required.
  • SNP (Special Needs Plans): Tailored for individuals with specific chronic conditions or those eligible for both Medicare and Medicaid.

Costs & Limits (2026)

  • Monthly Premium: Many plans are $0 premium. Beneficiaries must pay the standard Part B premium ($202.90).
  • Out-of-Pocket Cap: Federal maximum limit for in-network services: $9,250/year
  • Copays: A fixed copay is usually set for doctor visits or specialist services.
