FEHB Self Only vs Self Plus One in Retirement: Choosing the Right Enrollment Type

The Three FEHB Enrollment Types

FEHB offers three enrollment categories: Self Only (covers only the enrollee), Self Plus One (covers the enrollee plus one eligible family member), and Self and Family (covers the enrollee plus all eligible family members).

For active employees with multiple dependents, Self and Family is the default. But in retirement, family circumstances change. Children age out of eligibility. Spouses may gain their own coverage through Medicare, TRICARE, or a second career. The enrollment type that made sense at 45 may be costing you hundreds of dollars per month that you no longer need to spend.

Why Enrollment Type Matters More in Retirement

In retirement, every dollar of FEHB premium comes directly out of your annuity. The gap between enrollment types is substantial:

For a typical BCBS Standard plan in 2026, the biweekly retiree premium for Self and Family runs roughly $230–260, while Self Plus One costs approximately $195–230, and Self Only runs $90–110. Over a year, dropping from Self and Family to Self Only saves roughly $3,000–4,000 in premiums.

You can change enrollment types during any Open Season (mid-November through mid-December each year, effective January 1). You can also change due to a qualifying life event — a child aging out, a divorce, or a spouse gaining other coverage.

Self Plus One: The Sweet Spot for Most Retiree Couples

OPM added Self Plus One in 2016, and it filled a gap that retirees had complained about for decades. Before that, a retiree covering only a spouse had to pay the full Self and Family rate — the same as someone covering a spouse and four children.

Self Plus One typically costs 15–20% less than Self and Family. For a couple in retirement with no dependent children, switching to Self Plus One during Open Season is straightforward and saves real money with no loss of coverage.

The "Plus One" can be your spouse, an adult child under 26, or a former spouse who qualifies under Spouse Equity provisions. You designate who the Plus One is at enrollment — and if that person loses eligibility (through divorce, for example), you revert to Self Only or designate a different eligible family member.

When Self Only Makes Sense

Self Only is the cheapest option, and it works in two scenarios:

Your spouse has their own coverage. If your spouse has employer health insurance, Medicare with a Medigap supplement, TRICARE for Life, or VA coverage, doubling up with FEHB may not be worth the premium difference. Run the math: compare the Self Only premium plus your spouse's separate coverage costs against the Self Plus One premium covering both of you.

You are single, divorced, or widowed. If no eligible family members need coverage, Self Only is the obvious choice. Retirees who remain on Self and Family after children age out and a spouse passes away are paying several thousand dollars per year for coverage that covers no one besides themselves.

Survivor Annuity and Enrollment Type Are Linked

Here is the critical connection: your enrollment type at the time of death determines whether your surviving spouse can continue FEHB coverage.

If you die while enrolled in Self Only, your spouse has no FEHB coverage to continue — regardless of whether you elected a survivor annuity. The survivor annuity provides the recurring monthly payment that makes the spouse eligible for FEHB, but the enrollment itself must include the spouse at the time of death.

This means a retiree who drops to Self Only to save money and then dies unexpectedly leaves their spouse without FEHB, even if a full 50% survivor annuity was elected. The spouse would receive the annuity payment but could not use it to enroll in FEHB.

The safe approach: if your spouse needs FEHB as a survivor benefit, stay on Self Plus One or Self and Family for the duration of retirement. The premium savings of Self Only are not worth the risk if FEHB survivor coverage is part of your planning.

Medicare and Enrollment Type

When both spouses reach 65 and enroll in Medicare, the question of whether to keep FEHB at all — and at what tier — becomes more nuanced. Medicare becomes the primary payer, and FEHB shifts to secondary. Many major plans waive deductibles and copays entirely when Medicare Part B is primary, which means the FEHB plan costs you premiums but provides near-zero additional out-of-pocket savings on covered services.

Some couples keep Self Plus One for the prescription drug coordination (FEHB plans now integrate Medicare Part D via EGWPs with an approximately $2,100 annual out-of-pocket cap in 2026) and the safety net of secondary coverage for anything Medicare does not cover. Others drop to Self Only for one spouse and let the other spouse rely on Medicare plus a Medigap supplement.

The FEHB & Medicare Coordination Guide breaks down these scenarios by plan type, showing which FEHB carriers provide the best wrap-around value once Medicare is primary — so you can make the enrollment tier decision with actual cost data instead of guesswork.
