Understanding Changes in Medigap Coverage from January 1, 2020 Starting January 1, 2020, Medigap plans offered to new Medicare supplement insurance Texas beneficiaries were restricted from covering the Part B deductible. Consequently, both Plans C and F became unavailable to individuals new to Medicare from that date. However, if you were already enrolled in either of these plans, including the high deductible version of Plan F, or had coverage from these plans before January 1, 2020, you can retain your existing plan. For those eligible for Medicare before January 1, 2020, but not yet enrolled, the option to purchase Plans C and F or the high-deductible version of Plan F remains open. In addition to filling coverage gaps like the Part B deductible, certain Medigap policies provide coverage for services not covered by Original medicare supplements insurance New York, such as healthcare services when traveling outside the United States. If you opt to stay with Original Medicare and acquire a Medigap policy, Medicare will be the primary payer, and your Medigap policy will cover its share of the healthcare costs.
