QUESTION 1
Maria is turning 65 on September 15, 2026. She is currently covered under her
employer's group health plan through her job at a large company with 150 employees.
When is Maria's Initial Enrollment Period (IEP) for Medicare Part B?
A) September 15, 2026 only
B) June 1, 2026 through November 30, 2026
C) September 1, 2026 through November 30, 2026
D) June 15, 2026 through December 15, 2026
CORRECT ANSWER: B) June 1, 2026 through November 30, 2026
,RATIONALE: The Initial Enrollment Period (IEP) for Medicare begins 3 months before the
month of the individual's 65th birthday and ends 3 months after the month they turn 65.
Since Maria turns 65 in September 2026, her IEP runs from June 1, 2026 (3 months before
September) through November 30, 2026 (3 months after September). The 7-month
window is fixed by law and does not change based on employment status. Even though
Maria has employer coverage, she can choose to delay Part B without penalty if she has
credible coverage through her employer. However, the IEP dates themselves remain
unchanged. This is a common area of confusion for beneficiaries who assume employment
status affects enrollment period timing.
QUESTION 2
Robert, age 67, is currently enrolled in Medicare Part A only. He has been covered under
his wife's employer group health plan from a company with 25 employees. He wants to
enroll in Medicare Part B now. What enrollment period applies to Robert?
A) Initial Enrollment Period
B) General Enrollment Period
C) Special Enrollment Period
D) Annual Enrollment Period
CORRECT ANSWER: C) Special Enrollment Period
RATIONALE: Robert qualifies for a Special Enrollment Period (SEP) because he is still
covered under a group health plan based on current employment (his wife's employment).
The SEP allows individuals to enroll in Part B without penalty while they have employer
coverage, or within 8 months after the employment or coverage ends. However, there is a
critical distinction: the employer must have 20 or more employees for the SEP to apply
without penalty. Since his wife's company has 25 employees, the SEP applies. If the
employer had fewer than 20 employees, the SEP might not be available and he could face
a late enrollment penalty. The General Enrollment Period (B) runs January 1-March 31
,each year for those who missed their IEP. The Annual Enrollment Period (D) is October 15-
December 7 for Medicare Advantage and Part D changes, not for initial Part B enrollment.
QUESTION 3
During which of the following Medicare enrollment periods can a beneficiary enroll in a
Medicare Advantage plan for the first time?
A) Initial Enrollment Period only
B) Annual Enrollment Period only
C) Both Initial Enrollment Period and Annual Enrollment Period
D) Special Enrollment Period only
CORRECT ANSWER: C) Both Initial Enrollment Period and Annual Enrollment
Period
RATIONALE: Beneficiaries can enroll in a Medicare Advantage (MA) plan during multiple
enrollment periods. The Initial Enrollment Period (IEP) allows first-time enrollment when a
beneficiary turns 65 or qualifies due to disability. The Annual Enrollment Period (AEP),
which runs from October 15 to December 7 each year, also allows enrollment in MA plans,
including first-time enrollment. Additionally, Special Enrollment Periods (SEPs) may be
available for qualifying life events. Therefore, the correct answer is both the IEP and AEP. It
is important to note that the Medicare Advantage Open Enrollment Period (MA OEP) from
January 1 to March 31 is for switching between MA plans or disenrolling from MA to
Original Medicare, not for first-time enrollment.
QUESTION 4
, Susan turned 65 in January 2026 but did not enroll in Medicare Part B because she was
covered under her employer's plan. Her employer coverage ended on June 30, 2026. By
what date must Susan enroll in Part B to avoid a late enrollment penalty?
A) September 30, 2026
B) December 31, 2026
C) February 28, 2027
D) March 31, 2027
CORRECT ANSWER: C) February 28, 2027
RATIONALE: When employer coverage ends, the beneficiary has an 8-month Special
Enrollment Period (SEP) to enroll in Part B without penalty. The 8-month period begins
when the employer coverage ends OR when employment ends, whichever is earlier. Since
Susan's coverage ended on June 30, 2026, her 8-month SEP runs from July 1, 2026
through February 28, 2027. If she misses this deadline, she would have to wait for the
General Enrollment Period (January 1-March 31) and may face a late enrollment penalty
of 10% for each full 12-month period she was eligible but not enrolled. The penalty is
calculated based on the number of months without coverage multiplied by 10% of the
standard Part B premium.
QUESTION 5
James is currently enrolled in Medicare Part A and Part B. He wants to switch from
Original Medicare to a Medicare Advantage plan. What is the primary enrollment period
for this change?
A) January 1 - March 31 (MA OEP)
B) October 15 - December 7 (AEP)
C) April 1 - June 30
D) Any time during the year with no restrictions
