2018 Plan and Premium Information for Medicare Plans Offering Part D Coverage
8 Increased Initial Coverage Limit:  The Increased Initial Coverage Limit column specifies (with a "Yes") any plans that have increased the initial coverage limit applicable to Part D drugs (from the standard $3,750).
7 Tiers Not Subject to Deductible:  In 2018, plans can indicate tiers where the deductible does not apply. This is a flag to capture instances where the plan has some tiers that are exempt from the deductible.
6 Part D Premium Obligation with Full Premium Assistance:  This column indicates the total Part D premium a beneficiary receiving a full low-income subsidy would pay for a plan.  If column M, with the header "Part D Basic Premium Below Regional Benchmark?" in the states tabs, is listed as "Below Regional Benchmark" and the Part D Premium Obligation with Full Premium Assistance is <$2.00, then that portion is waived by the plan.
5 Part D Total Premium: The Part D Total Premium is the sum of the Basic and Supplemental Premiums.  Note: the Part D Total Premium is net of any Part A/B rebates applied to "buy down" the drug premium for Medicare Advantage plans; for some plans the total premium may be lower than the sum of the basic and supplemental premiums due to negative basic or supplemental premiums.
4 Part D Supplemental Premium:  The Part D Supplemental Premium covers any enhanced benefits that may be offered by a plan above and beyond the basic (standard) Part D benefit.  These benefits may include extra coverage in the coverage gap, lower copayments than the standard benefit, coverage of non-Part D drugs.  Note: the Part D Supplemental Premium is net of any Part A/B rebates applied to "buy down" the drug premium for Medicare Advantage plans.
3 Part D Basic Premium:  The Part D Basic Premium covers the basic prescription benefit only and does not cover enhanced drug benefits, medical benefits, or hospital benefits.  Note: the Part D Basic Premium is net of any Part A/B rebates applied to "buy down" the drug premium for Medicare Advantage plans.  Beneficiaries are also responsible for their Part B premium and any premiums for Medigap coverage to meet their individual needs.
2 Part C Premium:  The Part C premium for Medicare Advantage Plans, Cost Plans, and Demonstrations covers Medicare medical and hospital benefits, and supplemental benefits, where offered.  Beneficiaries generally are also responsible for the Part B premium.
