As a result of these changes and other administrative choices by Centers for Medicare and Medicaid Services (CMS, per-person expenditures for beneficiaries on Parts A/B/C and those not on A/B/C reached effective parity). One such choice ended the out-of-balance PFFS plan program except for grandfathered beneficiaries. The out-of-balance Employer Group plan program was cut back beginning in 2017.
When you apply for Medicare, you can sign up for Part A (Hospital Insurance) and Part B (Medical Insurance). Because you must pay a premium for Part B coverage, you can turn it down. However, if you decide to enroll in Part B later on, you may have to pay a late enrollment penalty for as long as you have Part B coverage. Your monthly premium will go up 10 percent for each 12-month period you were eligible for Part B, but didn’t sign up for it, unless you qualify for a special enrollment period.
