Key Takeaways
- Medigap covers costs like coinsurance and deductibles.
- Plans are standardized by letter.
- You can see any provider who accepts Medicare.
Medigap, also called Medicare Supplement insurance, is private coverage that pays for many of the out-of-pocket costs Original Medicare leaves behind — such as coinsurance, copays and deductibles.
Because Medigap plans are standardized by letter, a Plan G from one carrier offers the same benefits as a Plan G from another, so it pays to compare price and service.
