Average Medicare prescription drug plan premiums continue to fall

Medicare Part D plans are sold by private insurers and provide coverage for prescription medications. It is one of two ways for Medicare beneficiaries to obtain Medicare drug coverage, along with enrolling in a Medicare Advantage (Medicare Part C) plan that includes prescription drug coverage.

Part D premiums have been on the downswing in recent years, thanks in part to increasing enrollment and plan competition. Since 2017, Part D plan premiums have decreased by 12 percent.

“In short, Part D premiums continue to stay at their lowest levels in years even as beneficiaries enjoy a more robust set of options from which to choose a plan that meets their needs,” - CMS Administrator Seema Verma

The 12 percent decrease in premiums since 2017 has saved Medicare beneficiaries nearly $1.9 billion. Plan D enrollment has increased by 16.7 percent during that time, as around 200 new standalone Part D plans and 1,500 additional Medicare Advantage plans with drug coverage were introduced to the market.

Part D Senior Savings Model

Earlier in the year, CMS introduced the Part D Senior Savings Model, which allows Medicare beneficiaries to choose a Part D plan that provides access to insulin with a maximum copay of $35 for a one month’s supply.

The Senior Savings Model will be implemented on January 1, 2021.

Low-cost drug plan premiums announcement comes in time for Open Enrollment

Many Medicare beneficiaries will have their opportunity to enroll in a new Medicare Part D plan or Medicare Advantage plan with prescription drug coverage during the upcoming fall Medicare Annual Enrollment Period, also called AEP or the Medicare Open Enrollment Period for Medicare Advantage and prescription drug plans.

The fall Medicare Open Enrollment Period lasts from October 15 to December 7 and allows current beneficiaries the chance to sign up for, drop or change a Medicare Advantage plan or Medicare Part D plan. Any enrollment or disenrollment actions that beneficiaries take during AEP will become effective January 1, 2021.
