Still working at 65? Do not make the decision from age alone.
Some people can delay Part B without a penalty while covered by an employer group health plan based on current employment. Others need Medicare when they turn 65 for their job-based coverage to pay correctly. Retiree coverage and COBRA do not follow the same Part B enrollment rules as active-employment coverage.
Ask the employer or benefits administrator how the group plan coordinates with Medicare before you delay anything. When current employment or that coverage ends, Medicare generally provides an eight-month Special Enrollment Period for Part B, but the timing for joining a Medicare Advantage or drug plan is different. This is one of the situations where the dates should be checked against your exact coverage rather than remembered from a general rule.
A review can also identify what the employer plan does and does not address, without assuming you should leave it. In California, some supplemental options commonly considered as part of an Umbrella package have age-based eligibility, so it can be useful to review those choices while they are still available.
