Do retired federal employees need to enroll in Medicare if they already have FEHB coverage?

Question

Short answer: no, you're not required to enroll in Medicare if you have FEHB. Your FEHB coverage continues into retirement, and you won't lose it by skipping Medicare. But before you close this tab, there are a few things you really need to know, because this decision is a bigger deal than most federal retirees realize.

First, most people take Part A regardless. If you worked and paid Medicare taxes, Part A doesn't cost you a monthly premium, so there's usually no downside to having it.

Part B is where the real decision lives. Here's the catch that trips people up: once you're retired, FEHB doesn't count as coverage from active employment. That matters because if you skip Part B at 65 and change your mind years later, you'll pay a late enrollment penalty for the rest of your life, and you may have to wait for a general enrollment window to sign up. The flexibility you had while working goes away when you retire.

Why would you pay for Part B if FEHB already covers you? Because the two can work together, and many FEHB plans reduce your out-of-pocket costs when Medicare pays first. Some even help offset the Part B premium. For plenty of retirees the math works out in their favor, but it depends on your specific plan and situation, so it's worth sitting down and running the numbers before your window closes.

One piece of good news: FEHB drug coverage is considered creditable, so most federal retirees don't need to add separate drug coverage, and there's no penalty if you skip it.

The bottom line: you don't have to enroll, but the choice you make around your 65th birthday can follow you for life. This is one of those decisions worth talking through with someone before the deadline, not after.

Id like to answer. Medicare can really compliment FEHB IF you have a need for diverse coverage. Below is a short explanation for the types of Medicare available. Hope this helps.

Most retired federal employees who qualify for premium-free Part A choose to enroll when they become eligible. Since it usually doesn't require a monthly premium, it can provide additional coverage alongside FEHB.

Medicare Part B (Medical Insurance): Enrollment is optional. Part B has a monthly premium, so the decision depends on whether the additional coverage is worth the cost for you. Many retirees enroll because FEHB and Part B together often reduce or eliminate many out-of-pocket costs. Others decline Part B and rely solely on FEHB.

Medicare Part D (Prescription Drug Coverage): Most FEHB plans provide prescription drug coverage that's considered at least as good as standard Medicare Part D, so many federal retirees don't need a separate Part D plan.

Retired federal employees are generally not required to enroll in Medicare if they already have Federal Employees Health Benefits (FEHB) coverage. However, many choose to enroll in Medicare Part B because it can reduce out-of-pocket costs and work alongside their FEHB plan. Others keep only Medicare Part A, which is usually premium-free, and rely on FEHB for the rest of their coverage. The best choice depends on factors such as premiums, expected health care needs, and the specific FEHB plan benefits.

Melanie Blackston · Answer

No, civilian retired federal employees are not required to enroll in Medicare Parts A or B to keep their Federal Employees Health Benefits (FEHB) coverage. FEHB can remain your primary health insurance in retirement without Medicare. However, most people get premium-free Part A at age 65, while Part B requires a monthly premium.

Great question...... retired federal employees do not have to enroll in Medicare. However, Federal Employees are encourage to at least Enroll in Original Medicare- Part A (Hospital/Skilled Nursing Care) when they turn 65  because it will act as a supplement to their FEHB. 

FEHB retirees that elect to enroll in 
Medicare Part A (Premium Free If Earned Through Working Credits) and 
Part B (There is a Premium) 
are very wise. 

Why? It' s like having a Medicare Supplement Plan (the FEHB serve the purpose when added to Original Medicare) to cover cost shares/expenses not covered by Original Medicare. The two programs work well together to reduce out of pocket expenses for the beneficiary. 

Again, a federal employee (FEHB) retiree it is not required to enroll in Medicare, but it is certainly a wise option.

Justin Lester · Answer

It depends. Most retired federal employees keep their FEHB coverage, but many still enroll in Medicare Part A because it's usually premium-free. Whether to enroll in Part B depends on their health needs, costs, and how they want FEHB and Medicare to work together. It's worth reviewing your options before deciding.

FEHB coverage refers to Federal Employees Health Benefits coverage. Typically, Medicare is optional. BUT there are exceptions to this. I would recommend getting together and going over all of your options before deciding to add or not to add Medicare Health benefits.
