MODULE 1: MEDICARE BASICS (PARTS A, B, C, D)
QUESTION 1
Mrs. Chen is 67 years old and has been enrolled in Original Medicare Parts A
and B.
She asks you whether she needs to enroll in Part D prescription drug coverage.
Which of the following is the MOST accurate response?
A) Part D enrollment is optional for all Medicare beneficiaries with no penalties.
B) Part D enrollment is mandatory for all Medicare beneficiaries.
C) Part D enrollment is optional, but if she does not enroll when first eligible
and does not have creditable coverage, she may face a late enrollment
penalty.
D) Part D enrollment is only available to those enrolled in Medicare Advantage
plans.
Correct Answer: C
EXPANDED RATIONALE:
Choice C is correct because Medicare Part D prescription drug coverage is
explicitly voluntary, not mandatory. However, the Medicare Modernization Act
establishes a strict "creditable coverage" rule. If a beneficiary declines Part D
when first eligible (during their Initial Enrollment Period) and goes 63 or more
consecutive days without other creditable coverage (coverage that is actuarially
equivalent to standard Part D), they will incur a Late Enrollment Penalty (LEP).
This penalty is calculated as 1% of the national base beneficiary premium for
every full month they went without coverage, and it is added permanently to
their monthly premium. Choice A is incorrect because it falsely states there are
"no penalties"—the LEP is a significant financial consequence. Choice B is
incorrect
1
,because enrollment is not mandatory; beneficiaries can opt out entirely,
though
it is generally unwise to do so without other coverage. Choice D is incorrect
because Part D is available as a standalone Prescription Drug Plan (PDP) to
beneficiaries in Original Medicare, not exclusively to Medicare Advantage
enrollees.
QUESTION 2
Mr. Kowalski is turning 65 next month and is currently covered under his
employer's group health plan through his job at a large corporation with over
20 employees. He asks if he must enroll in Medicare Part A immediately. What
should you tell him?
A) He must enroll in Part A immediately to avoid lifelong penalties.
B) He can delay Part A without penalty as long as he has employer coverage
from a large employer (20+ employees).
C) Part A is always free, so he should enroll regardless of other coverage.
D) He cannot delay Part A under any circumstances, even with employer
coverage.
Correct Answer: B
EXPANDED RATIONALE:
Choice B is correct because the Medicare Secondary Payer (MSP) rules
explicitly allow beneficiaries who have group health plan coverage through their
own current employment (or a spouse's employment) with an employer of 20 or
more employees to delay enrolling in Part A without facing any late enrollment
penalty. This is because the large employer plan pays primary, and Medicare
pays secondary. Choice A is incorrect because there is no "immediate"
mandate in this scenario; he has a Special Enrollment Period (SEP) to enroll
later without penalty when the employer coverage ends. Choice C is incorrect
because Part A is not always
free—it is premium-free only for those who have accumulated 40 quarters
(about 10 years) of Medicare-covered employment. If Mr. Kowalski does not
have 40
2
,quarters, he would have to pay a premium for Part A, making it unwise to enroll
if he already has good employer coverage. Choice D is flatly false because
delays are explicitly permitted under these specific employment circumstances.
QUESTION 3
Which of the following services is covered under Medicare Part A (Hospital
Insurance)?
A) Annual wellness visit.
B) Outpatient surgery.
C) Inpatient hospital stay.
D) Routine eye exam.
Correct Answer: C
EXPANDED RATIONALE:
Choice C is correct because Medicare Part A specifically covers inpatient
hospital care, including semi-private rooms, meals, general nursing, and other
hospital services and supplies. It also covers skilled nursing facility care
(after a qualifying hospital stay), hospice care, and some home health care.
Choice A is incorrect because the annual wellness visit is covered under Part B
(Medical Insurance), not Part A; it is a preventive service designed to develop
or update a personalized prevention plan. Choice B is incorrect because
outpatient surgery is generally covered under Part B, as it does not involve
an overnight hospital admission (it falls under ambulatory surgical center
services). Choice D is incorrect because routine eye exams for prescribing
glasses or contact lenses are explicitly excluded from Original Medicare
coverage (Part B only covers limited eye care for diabetic retinopathy or
after cataract surgery with an intraocular lens).
QUESTION 4
Medicare Part B covers which of the following services?
A) Prescription drugs taken at home.
3
, B) Inpatient psychiatric care.
C) Physician services and outpatient care.
D) Long-term custodial care in a nursing home.
Correct Answer: C
EXPANDED RATIONALE:
Choice C is correct because Medicare Part B is the medical insurance
component
of Original Medicare, covering physician services, outpatient hospital care,
durable medical equipment (DME), laboratory tests, mental health outpatient
services, and a wide range of preventive services. Choice A is incorrect
because
prescription drugs taken at home are covered under Medicare Part D (or a
Medicare Advantage plan with drug coverage), not Part B (Part B only covers
very limited drugs, such as those administered in a physician's office or
infusion drugs). Choice B is incorrect because inpatient psychiatric care is
covered under Part A, which includes up to 190 days of inpatient psychiatric
hospital services over a lifetime. Choice D is incorrect because Medicare does
not cover long-term custodial care (help with activities of daily living like
bathing, dressing, or eating) in a nursing home; it only covers skilled nursing
or rehabilitation care on a short-term basis after a qualifying hospital stay.
QUESTION 5
What is the primary difference between Medicare Part A and Part B regarding
beneficiary premiums?
A) Part A always has a monthly premium, while Part B is free.
B) Part B always requires a monthly premium, while Part A may be premium-
free if the beneficiary has 40 or more quarters of Medicare-covered
employment.
C) Both Part A and Part B have the exact same monthly premium amount.
D) Neither Part A nor Part B requires a premium for beneficiaries with low
incomes.
