If a person does not enroll in Medicare Part B (out-patient care and doctor visits) when first
eligible, and they do not have health coverage from an employer group health plan,
they will incur a late-enrollment penalty if they later choose to enroll in Medicare Part B.
This is also true if someone has Medicare Part B, but then drops their Part B coverage, and then later decides to sign up again for coverage.
Remember, if a person does not enroll in Medicare Part A and/or Medicare Part B when they were first eligible, and they were not eligible for a
Special Enrollment Period, they can only elect Medicare Part A or Medicare Part B during the
General Enrollment Period
that starts January 1st and continues through March 31 of each year.
The Medicare Part B late-enrollment penalty is 10% of the current Medicare Part B premium for every 12-month
period that the person delayed enrolling in Medicare Part B after they were first eligible or dropped Part B and were without Medicare Part B coverage when they were eligible.
For example, the 2019 standard Medicare Part B premium is $144.60
(for most people), so if a person delays enrolling in Medicare Part B (and has no employer coverage) for 12 months, they will have a 10% penalty of $14.40 in 2020.

The Medicare Part B penalty is permanent
and will be paid for as long as the person has Medicare Part B coverage.

and/or Medicare Part B starting the month after the employment ends or the

The Medicare Part B Initial Enrollment Period
A person can enroll in Medicare Part B during their 7-month Initial
Enrollment Period when they first become eligible for Medicare (3 months
before the Medicare eligibility month, plus the month a person turns
65, and including the 3 months after the month a person turns 65). During the 7-month Initial Enrollment Period a person can also enroll in
Medicare Part A, if they were not already automatically enrolled.
