ACRONYMS
o
- OEOpen enrollment is a designated, usually annual, time-limited period when individuals can sign up for, change, or cancel insurance plans—commonly employer-sponsored health, dental, or vision coverage. It acts as a set window, often in the fall, allowing enrollment without proof of insurability, meaning pre-existing conditions are covered.
- OEPIThe Medicare Open Enrollment Period for Institutionalized Individuals (OEPI) is a special, continuous enrollment period for Medicare beneficiaries living in institutions (like nursing homes) or receiving skilled nursing care. It allows them to change, join, or drop Medicare Advantage (MA) plans, including MAPD plans, at any time while institutionalized, plus two months after leaving.
- OSBOptional Supplemental Benefits (OSB) are additional, non-Original Medicare benefits offered by Medicare Advantage plans for an extra monthly premium. They allow members to purchase coverage for services like comprehensive dental, vision, hearing, and wellness programs. These differ from mandatory benefits by requiring separate enrollment.
