Introducing PSHB for federal employees
The Postal Service Health Benefits (PSHB) Program is a newer addition designed specifically for United States Postal Service (USPS) employees, retirees, and their families. While similar in structure to FEHB, PSHB addresses the healthcare needs of postal workers, reflecting their unique requirements. Those eligible for PSHB have access to a tailored selection of plans under this program, which is replacing FEHB for most USPS retirees starting in 2025.
What Is Medicare and Who Qualifies?
Medicare parts explained
Medicare is a federal health insurance program most commonly available to people aged 65 or older. It is made up of different parts: Part A covers hospital stays, Part B covers doctor visits and outpatient care, and Part D offers prescription drug coverage. Some people also choose to add Part C (Medicare Advantage), which bundles coverage with private health plans, but Parts A, B, and D form the foundation for most retirees.
Eligibility for federal retirees
As a federal retiree, you are typically eligible for Medicare once you reach age 65, regardless of whether you’ve already retired. You usually qualify for premium-free Part A based on your work history. It’s important to know that FEHB or PSHB eligibility and Medicare eligibility do not affect each other—qualifying for one does not take away your right to enroll in the other.
Can You Keep FEHB or PSHB With Medicare?
Rules for keeping federal health benefits
In most cases, you may continue your FEHB or PSHB coverage after enrolling in Medicare. You must have been continuously enrolled in FEHB (or another qualifying plan) for the five years immediately before retiring. Meeting these rules allows you to keep your federal health benefits as a retiree.
Enrollment considerations at age 65
At age 65, you become eligible for Medicare. Federal retirees are not required to enroll in Medicare, but many choose to sign up for Part A and/or Part B to supplement existing federal coverage. If you qualify for PSHB, enrolling in both Medicare Parts A and B may be required for maximum coverage, especially as new postal retiree plan rules are implemented.
How Do FEHB, PSHB, and Medicare Work Together?
Coordination of benefits explained
When you have both FEHB or PSHB and Medicare, the two programs “coordinate benefits.” This means they share the responsibility for your healthcare expenses. Medicare usually pays first (primary), and your federal plan acts as secondary coverage, stepping in to pay certain costs that Medicare may not cover. This can create more complete protection and may reduce or eliminate many out-of-pocket expenses.
Paying premiums and out-of-pocket costs
You are responsible for the premiums of both your federal health plan and any applicable Medicare premiums. While this means an additional monthly cost, having both types of coverage may lead to fewer expenses when you visit doctors, get lab work, or are hospitalized. It’s important to review the costs of all plans each year and consider how they fit within your retirement budget.
Which Pays First: FEHB/PSHB or Medicare?
Primary versus secondary payer rules
When you are retired and eligible for Medicare, Medicare generally becomes the primary payer, while your federal health plan becomes secondary. This means Medicare pays your health providers first; then, FEHB or PSHB may help pick up additional allowed costs. There are a few exceptions—such as if you’re still employed by the federal government after age 65—so it is wise to confirm your specific situation with your benefits advisor.
Impact on healthcare coverage
With Medicare as primary and your federal plan as secondary, you could benefit from more complete healthcare protection. Many retirees find that this double layer of coverage reduces their out-of-pocket medical expenses for a range of services. However, some services may only be covered by one plan. Understanding who pays first helps you anticipate what is and isn’t covered.
Do You Need Both FEHB/PSHB and Medicare?
Common scenarios and coverage options
Some federal retirees decide to keep both their federal health plan and Medicare for broader coverage and lower out-of-pocket risk. Others, based on their unique health situation, may consider adjusting parts of their coverage after reviewing costs and coverage gaps. For USPS retirees in particular, future PSHB rules may affect options, so staying informed is key.
Factors to consider before changing coverage
Think about your overall health, regular healthcare needs, and budget. Consider how both FEHB/PSHB and Medicare premiums fit your retirement income, and whether you anticipate significant medical expenses that could be better covered with both plans. Changing coverage is an important decision, and reviewing all options annually can help you stay protected.
How Can Healthcare Expenses Affect Retirement Assets?
Planning for medical costs in retirement
Healthcare can become a significant part of your retirement budget. Medical costs, premiums, and unexpected illnesses may impact your savings. By coordinating benefits and planning in advance, you can reduce surprises and protect your assets from unexpected expenses.
Considering asset allocation alongside benefits
When deciding how to spend or invest retirement savings, factor in ongoing healthcare expenses. Consider setting aside a portion of your assets to cover premiums and out-of-pocket costs, so healthcare needs do not disrupt your broader financial goals. Reviewing your retirement plan every year is a smart step.
What Questions Should Retirees Ask?
Topics to discuss with benefits advisors
Before making any coverage changes, ask your benefits advisor about how plan rules may change when you reach Medicare age, which plan pays first, and how out-of-pocket limits work with dual coverage. Knowing what to expect can help you make better decisions.
Evaluating your health coverage annually
Every year, review your coverage, premiums, and network options. Plans can and do change, and your healthcare needs might, too. Regular check-ins ensure you are still getting the protection you need.
