Understanding Medicare Supplement Plan C
Medicare Supplement Plan C, also known as Medigap Plan C, was designed to work alongside Original Medicare (Parts A and B) to cover many of the gaps that Original Medicare doesn’t address. This supplemental insurance helps pay for deductibles, coinsurance, and copayments that would otherwise come out of your pocket.
What Plan C Covers
Plan C provides comprehensive coverage that includes:
- Part A deductible: Covers the annual hospital deductible, which is $1,632 in 2024
- Part A coinsurance: Pays for hospital coinsurance costs for extended stays
- Part B deductible: Covers the annual medical deductible of $240 in 2024
- Part B coinsurance: Handles the 20% coinsurance for doctor visits and outpatient services
- Part B excess charges: Protects against charges above Medicare’s approved amounts
- Foreign travel emergency: Provides coverage for emergency care while traveling abroad
- Skilled nursing facility coinsurance: Covers coinsurance costs for skilled nursing care
This comprehensive coverage means that once you have Plan C, you typically won’t pay anything out-of-pocket for Medicare-approved services, except for your monthly premium.
Current Availability and Important Changes
Who Can Enroll
Plan C is no longer available to new Medicare beneficiaries who became eligible on or after January 1, 2020. This change occurred due to the Medicare Access and CHIP Reauthorization Act of 2015, which eliminated Medigap plans that cover the Part B deductible for new enrollees.
However, if you were already enrolled in Plan C before January 1, 2020, or if you became eligible for Medicare before that date, you may still be able to purchase Plan C during certain enrollment periods.
Enrollment Periods
You can enroll in Plan C during:
- Open Enrollment Period: Six months after you turn 65 and enroll in Medicare Part B
- Guaranteed Issue Rights: Specific circumstances that guarantee your right to buy certain Medigap policies
- State-specific enrollment opportunities: Some states offer additional enrollment periods
For detailed information about enrollment periods and eligibility requirements, visit the official Medicare website at Medicare.gov.
Comparing Plan C to Other Options
Plan C vs. Plan F
Both Plan C and Plan F offer comprehensive coverage, but Plan F doesn’t include coverage for Part A and Part B deductibles that Plan C provides. Plan F is also subject to the same availability restrictions as Plan C for new Medicare beneficiaries.
Plan C vs. Plan G
Plan G has become increasingly popular as an alternative to Plan C. While Plan G doesn’t cover the Part B deductible, it offers all other benefits that Plan C provides. Plan G remains available to all Medicare beneficiaries and often has lower monthly premiums.
High-Deductible Options
Some insurers offer a high-deductible version of Plan C, which requires you to pay a higher deductible ($2,700 in 2024) before coverage begins, but typically comes with lower monthly premiums.

Frequently Asked Questions
Can I switch from Plan C to another Medigap plan?
You can switch plans during certain periods, but you may need to undergo medical underwriting unless you have guaranteed issue rights. The best time to make changes is during your Open Enrollment Period when you first become eligible for Medicare.
Will Plan C premiums increase over time?
Yes, like all Medigap plans, Plan C premiums typically increase annually. The rate of increase depends on your insurance company’s pricing method and can vary by location and age.
Does Plan C cover prescription drugs?
No, Plan C does not include prescription drug coverage. You’ll need to enroll in a separate Medicare Part D plan for prescription drug coverage, and it’s important to do so to avoid late enrollment penalties.
