(CMS) updates cost-sharing requirements for the various parts of Medicare


On October 12, 2023, CMS released the updated figures for 2024. Here’s what beneficiaries need to know.


MEDICARE PART A COST-SHARING INCREASED

99% of Medicare beneficiaries pay no Part A premium, due to them having paid FICA taxes for over 40 quarters. For those who have not met that requirement, they will see modest increases in their monthly premium payments. See the table below.

2024

Enrollees over age 65, contributed to FICA for 40+ quarters

Enrollees over age 65, contribute to FICA for 30-39 quarters

$278

$278

Enrollees over age 65, contributed to FICA for fewer than 30 quarters

Regardless of what they pay (or not!) in premium, all Part A beneficiaries are subject to cost-sharing for any inpatient care they receive – whether that care occurs in a hospital or a skilled nursing facility. Cost sharing for Part A is based on benefit periods. The table below details what beneficiaries can expect to pay for each type of service.

INCREASE IN PART B PREMIUM, DEDUCTIBLE; IRMAA BRACKETS ADJUSTED

The base premium for full Part B will increase from $164.90 per month to $174.70 per month. The change is a result of a projected increase in healthcare spending.

Since 2007, a beneficiary’s monthly part B premium has been dependent on income and tax filing status. Income-related monthly adjustment amounts impact about 8% of enrollees. Total premiums for a variety of income brackets and filing statuses are shown in the tables below. Note these brackets have shifted some, as a result of inflationary pressures.
