Moving forward, Medicare Advantage plans with prescription drug coverage will also be subject to some of the same forces that are driving Part D costs higher, the report warns, meaning that Americans should take a long-term view when making decisions about sourcing coverage.

“For many, retirement healthcare costs will include a combination of Medicare Parts B, D and supplemental insurance premiums, and related out-of-pocket costs such as co-pays, as well as expenses for dental, vision and hearing,” the report explains.

View by State

HealthView’s analysis of publicly available Part D premium data from three large plan providers serving California, Florida, Texas, New York and Pennsylvania shows increases in plan costs across the board.

The tables in the analysis show that average Part D premiums will rise by 30% in Texas and 53% in New York, with a range of growth in plan prices across the five states between 21% and 77%. There is an average of a 42% hike for high-end plans — which are popular among advisors’ clients and represent the smallest increase in 2024 costs by percentage growth.

With key provisions of the Inflation Reduction Act set to be enacted in 2025, the analysis warns, it is possible that the increase in Part D premiums may continue for another year, even as the broader public discussion focuses on falling Medicare costs.

“Assuming a two-year 42% per annum cost increase for higher-end plans (consistent with data in this report) with a return to normalized inflation rates thereafter, Medicare Part D premiums would increase from 8.7% to 14.7% of lifetime healthcare spend for [a theoretical couple],” the report notes.

Since about 25% of retirees are expected to exceed the Part D $2,000 limit, around 75% will face higher premiums with no reduction in co-pays due to the lower catastrophic limit — although they may experience relief through capped insulin prices or drugs that are negotiated by the federal government through different components of the Inflation Reduction Act.

Implications for Advisors and Clients

According to HealthView Services, early indicators from the five states with the highest 65-plus population show that Part D coverage will be significantly more expensive for many Americans in 2024.

As the report notes, an increase in Part D premiums of several hundred dollars a year may not seem that much until it is put in the context of this year’s Social Security COLA.

“The added cost for high-end Part D premiums (among the plans detailed in this report) will on its own account for 54% of the average cost-of-living increase that retirees will receive in federal benefits,” the authors warn. “Add in Part B premiums increases, and that number jumps to 70%.”

As such, advisors and clients need to be clear about what this means in practice.

“Over the course of retirement, our data continues to show healthcare costs continuing to rise faster than CPI, driven by premium inflation, out-of-pocket cost inflation, age rating for supplemental insurance, and the greater utilization of services,” the report warns. “This means that healthcare costs will be far higher at the end of retirement than at the beginning.”

Ultimately, greater Part D premiums are a part of this overall picture and may add an additional $53,000 in lifetime premiums for the typical couple, based on the most recent two-year inflation rate of 42%.

“Ensuring funds will be available to address medical needs through retirement is a planning, investment and decumulation challenge,” the report warns.
