According to The Wall Street Journal (4/23/19) the cost of Medicare part B premiums for 2020 will likely increase $8.80/month from $135.50 to $144.30. The previous increase was from $134 in 2018.
While Medicare part A that covers hospitalization is usually free for most Americnas 65 and older, Part B charges a monthly premium that ranges from $135.50 to $460.50 depending on income.
Most retirees also purchase private supplemental policies or Medicare Advantage Plans (that charge premiums, co-payments and deductibles) to cover expenses not included in Medicare.
So retirees and soon-to-be retired persons need to plan for rapidly increasing health care costs in retirement.
