Some insurance companies may elect to sell Medigap (Supplemental) policies to individuals under age 65, even in states that do not require this policy. If you do not have prescription drug coverage from another source, it is important to enroll in a Medicare Part D (PDP) Plan. Alternatively, you can explore when to sign up for Medicare Advantage Plans offered by private insurance companies, which encompass your Medicare-covered benefits, including prescription drugs. These include options like HMOs or PPOs; however, keep in mind that access to providers may be more limited. Importantly, Medicare Advantage Plans cannot deny coverage to people with Medicare based on their health status or pre-existing conditions.
