Final answer:
GI refers to Gastrointestinal in a medical context or to the Montgomery GI Bill for veterans. Medigap is a Medicare Supplement Insurance, and during the Medigap open enrollment period, veterans have guaranteed issue rights to sign up for various plans without medical underwriting.
Step-by-step explanation:
When we refer to GI in a medical context, it typically stands for Gastrointestinal, which is related to the stomach and intestine. However, when talking about insurance and benefits for veterans, GI stands for the Montgomery GI Bill, which is designed to help veterans by providing funds for college or a trade school after their military service.
If you are a veteran looking to benefit from the GI Bill, you may also hear about Medigap plans during your GI window. The term Medigap refers to Medicare Supplement Insurance plans, which help cover some of the healthcare costs that Original Medicare doesn't cover.
To qualify for a Medigap plan without medical underwriting, you must apply during your Medigap open enrollment period, which starts the first month you have Medicare Part B and are 65 or older. During this period, you have a guaranteed issue right, meaning Medigap policy issuers can't deny you coverage due to pre-existing conditions. Among the standardized Medigap plans available, which one you can sign up for may differ by state, but could include Plan A, B, C, D, F, G, K, L, M, or N.
