2018 MA and PDP premium, bid amount, related information released

Important 2018 Medicare Part D prescription drug plan (PDP) and Part C Medicare Advantage (MA) information for MA organizations and PDP sponsors has been announced by CMS. The information includes the average basic premium for a PDP, the Part D national average monthly bid amount, the Part D base beneficiary premium, the income-related monthly adjustment amount (IRMAA) for enrollees in PDPs who have incomes above certain threshold amounts, the Part D regional low-income premium subsidy amounts, the MA regional preferred provider organization (PPO) benchmarks, and the MA employer group waiver plan (EGWP) regional payment rates.

Average basic PDP premium

The average premium for 2018 is based on bids submitted by drug plans for basic drug coverage for the 2018 benefit year and calculated by the independent CMS Office of the Actuary. The average basic premium for a PDP in 2018 is projected to decline to an estimated $33.50 per month. This represents a decrease of approximately $1.20 below the actual average premium of $34.70 in 2017. The decline comes despite the fact that spending for the Part D program continues to increase faster than spending for other parts of Medicare, largely driven by spending on high-cost specialty drugs.

Part D national average monthly bid amount

CMS computes the national average monthly bid amount from the applicable Part D plan bid submissions in order to calculate the base beneficiary premium. The national average monthly bid amount is a weighted average of the standardized bid amounts for each stand-alone PDP and MA prescription drug plan (MA-PD). The calculation does not include bids submitted by Medicare medical saving account plans, MA private fee-for-service plans, specialized MA plans for special needs individuals, Program of All-Inclusive Care of the Elderly (PACE) programs, any “fallback” PDPs, and plans established through reasonable cost reimbursement contracts. The reference month for the 2018 calculation was June 2017. The national average monthly bid amount for 2018 is $57.93.

Part D base beneficiary premium

The base beneficiary premium is equal to the product of the beneficiary premium percentage and the national average monthly bid amount. Part D beneficiary premiums are calculated as the base beneficiary premium adjusted by the following factors: (1) the difference between the plan’s standardized bid amount and the national average monthly bid amount; (2) an increase for any supplemental premium; (3) an increase for any late enrollment penalty; (4) a decrease for MA-PDs that apply MA A/B rebates to buy down the Part D premium; and (5) elimination or decrease with the application of the low-income premium subsidy. The Part D base beneficiary premium for 2018 is $35.02. In practice, actual premiums vary significantly from one Part D plan to another and seldom equal the base beneficiary premium.

Income-related monthly adjustment amount (IRMAA)

If a beneficiary’s “modified adjusted gross income” is greater than the specified threshold amounts ($85,000 in 2018 for a beneficiary filing an individual income tax return or married and filing a separate return, and $170,000 for a beneficiary filing a joint tax return), then the beneficiary is responsible for a larger portion of the total cost of Part D benefit coverage. Therefore, in addition to the normal Part D premium paid to a plan, such beneficiaries must pay an IRMAA to the standard base beneficiary premium of $35.02 for 2018. Beneficiaries do not pay the IRMAA to the Part D plan; instead, IRMAAs are collected by the federal government.

Part D regional low-income premium subsidy amounts

Full low-income subsidy (LIS) individuals are entitled to a premium subsidy equal to 100 percent of the premium subsidy amount. A Part D plan’s premium subsidy amount is the lesser of the plan’s premium for basic coverage or the regional low-income premium subsidy amount (LIPSA). The 2018 regional LIPSAs are available through the CMS website.

MA regional PPO benchmarks

The standardized PPO benchmark for each MA region is a blend of: (1) a statutory component consisting of the weighted average of the county capitation rates across the region for each appropriate level of star rating; and (2) a competitive, or plan-bid, component consisting of the weighted average of all of the standardized A/B bids for regional MA PPO plans in the region. For 2018, the national weights applied to the statutory and plan-bid components are 66.5 percent and 33.5 percent, respectively.

Beginning in 2017, these benchmarks reflect the average bid component of the regional benchmark excluding EGWPs. The statutory and plan-bid components of the MA regional standardized benchmarks for 19 of the 26 MA regions are available from CMS. In the remaining seven MA regions, there are no regional MA plans.

MA regional EGWP payment rates

For detailed descriptions of the payment policy finalized for 2018 MA regional EGWP payment rates see the 2018 Advance Notice and Rate Announcement. The payment rates for Regional EGWPs are in the file Regional Rates and Benchmarks 2018 which can be accessed on the CMS website.

Medicare Advantage looks forward to a stable new year

The Medicare Advantage (MA) market appears that it will remain relatively stable in 2017, undergoing limited changes in average premiums, plan offerings, and insurer participation, according to a Kaiser Family Foundation (KFF) Issue Brief. While KFF determined that factors like plan availability, premiums, out-of-pocket limits, and other plan features, suggest a stable market, the Issue Brief warns that lawmakers’ plans proposing to transform Medicare into a “premium support system” could have uncertain consequences for both plans and beneficiaries.

Plans

The Issue Brief points to the following highlights for MA plans in 2017:

  • with a total of 2,034 MA plans offered in 2017, the average MA beneficiary will be able to choose between 19 plans (a number which has remained stable since 2012);
  • the average MA beneficiary will have a choice of plans offered by six firms;
  • enrollees in MA prescription drug plans (MA-PDs) who stay in the same plan between 2016 and 2017, will experience, on average, a premiums increase of 4 percent;
  • premiums remain relatively flat while out-of-pocket costs for Part A and B benefits have increased by 25 percent, since 2011, to $5,332 in 2017; and
  • about 41 percent of MA plans are rated as 4 stars or higher in 2017.

Shortcomings

The Issue Brief notes that it remains difficult for consumers and researchers to obtain the information necessary to allow plan comparisons. Specifically, it is difficult to find data to compare plan networks, cost sharing, extra benefits, or the performance of individual plans on quality and efficiency metrics. Access to such material could be helpful in strengthening program oversight and assisting consumers with making appropriate plan choices.

Medicare Transformation

KFF acknowledges that some lawmakers are planning to build off of the MA model to transform Medicare into a “premium support system.” The Issue Brief warns that such a transformation would constitute a significant departure from the status quo, in terms of altering federal payments to plans and plans’ financial incentives—changes with unknown impact for Medicare and its beneficiaries.
