Each year the Medicare premiums, deductibles, and copayment rates are adjusted according to the Social Security Act. For 2020, the Medicare Part B monthly premiums and the annual deductible are higher than the 2019 amounts. The standard monthly premium for Medicare Part B enrollees will be $144.60 for 2020, an increase of $9.10 from $135.50 in 2019. The annual deductible for all Medicare Part B beneficiaries is $198 in 2020, an increase of $13 from the annual deductible of $185 in 2019.
The increase in the Part B premiums and deductible is largely due to rising spending on physician-administered drugs. These higher costs have a ripple effect and result in higher Part B premiums and deductible.
