JUSTICE IN AGING | ISSUE BRIEF | www.justiceinaging.org | 2
Enrollees with both Part A and Part B coverage
have the option to receive their benets through
managed care, called Medicare Advantage (MA). e
Centers for Medicare and Medicaid Services (CMS)
administers enrollment for both Part D and Medicare
Advantage.

Many older immigrants who immigrated
later in life have little or no work history in the United
States, which aects their Medicare costs, and, in some
cases, their eligibility.
Premium Costs for Medicare
Part A premiums, which are tied to work history,
can be a particular challenge for some immigrants.
Nearly all (99%) Medicare enrollees qualify for Part
A coverage without paying a premium (“premium-free
Part A”) based on their work credits (generally 40
quarters,approximately ten years) or on the work
credits of their spouse.
3
However, those without the
required work credits must pay high premiums for Part
A coverage, up to $505/mo. in 2024.
4
Note that work
credit requirements are dierent for people qualifying for
Medicare on the basis of disability and that there also are
unique rules for people with End Stage Renal Disease
(ESRD).
5
Regardless of work history, Medicare Part B requires a
premium payment, which for 2024 is $174.90/month.
6
To purchase Part A, an individual must also enroll in
Part B. In contrast, it is possible to enroll only in Part B
and forgo Part A coverage. Both Part A and Part B have
late enrollment penalties that may apply to individuals
who do not enroll when rst eligible.
7
Medicare Part D Prescription Drug Plans (PDPs)
also have premiums that vary depending on the
plan, as well as late enrollment penalties for delays
in enrollment.
8
Individuals can enroll in the Part D
prescription drug benet if they have either Part A or
Part B coverage.
