Open Enrollment Period

Open Enrollment Period refers to the one-time Medicare Supplement enrollment window during which eligible beneficiaries may purchase Medigap coverage without medical underwriting.

🧠 Full Definition

Open Enrollment Period is a one-time six-month Medicare Supplement enrollment window that begins when an individual is both age 65 or older and enrolled in Medicare Part B coverage.

During this period, eligible beneficiaries may purchase any Medigap policy available in their state without being denied coverage or charged higher premiums because of past or current health conditions.

The Open Enrollment Period provides important guaranteed issue protections that help beneficiaries obtain Medicare Supplement coverage without medical underwriting restrictions.

📌 Key Characteristics
