What is Medicare Supplement Plan D?

Medigap Plan D can be easy to confuse with Medicare Part D. Additionally, the names Medicare Supplement Plan D and Medicare Plan D are synonymous, however, they are not the same thing as Medicare Part D, which is a government-issued policy for prescription drug coverage. Where one is a policy offered by the government, Medicare Supplement Plan D 2021 is offered by insurance carriers, representing one of the 10 standardized Medigap Plans.

This policy assists in paying some of the expenses that Original Medicare does not cover. These expenses are generally copays, coinsurance, and deductibles. Medicare Supplement Insurance Plan D only works with Original Medicare, and you must be enrolled in both Parts A & B to enroll in the policy.
