Every Family Member Added at Open Season Now Gets Verified: OPM’s 2027 Rule

For the past two Open Seasons, agencies had to check the paperwork on a sample of enrollments that added a spouse or child. For the coming one, the sample is everybody.

The short answer: FEHB Open Season verification becomes universal for plan year 2027. OPM has told agencies they must verify 100 percent of Open Season elections in which a family member is added, and the requirement now sits in statute rather than in agency guidance.

Status as of September 3, 2026. This post covers a developing matter and is not updated continuously.

What changed for plan year 2027?

In Benefits Administration Letter 26-202, dated July 15, 2026, OPM notified agency benefits officers that “beginning with Open Season for Plan Year 2027, employing offices must verify 100 percent of Open Season elections in which a family member is added.”

The authority is the FEHB Protection Act of 2025, enacted as Section 90101 of Public Law 119-21. OPM’s letter says the Act “codifies and elevates this standard by requiring verification of family member eligibility when an enrollee adds a family member during Open Season.”

The letter sets a second date too: beginning July 4, 2026, 100 percent of qualifying life events resulting in a family member being added must be reviewed and the QLE itself verified. All of this applies to both FEHB and the Postal Service Health Benefits Program.

How is this different from the rule that took effect in July?

It is the next rung of the same ladder, and the difference is scope and force. OPM has tightened family member verification in stages: BAL 24-201 and BAL 24-204, issued after a Government Accountability Office report, set a minimum review requirement of 10 percent of Self Plus One and Self and Family Open Season elections while recommending review of all of them. BALs 25-201 and 26-201 reinforced that.

Two things are new. The floor moves from 10 percent to 100 percent, and the requirement stops being a recommendation backed by guidance and becomes a statutory obligation. Our earlier post on the FEHB eligibility verification rule covers the underlying framework and the July 2026 effective date; this covers what the Open Season layer adds on top.

What documentation does FEHB Open Season verification require?

OPM’s instruction to employing offices is direct: they “must request and evaluate the proof-of-relationship document(s) for every Open Season election in which a family member is added.”

The proof turns on the relationship claimed. OPM’s family member reference materials describe the categories of acceptable documentation:

• Spouse — evidence of a valid marriage.
• Child under 26 — evidence of the parent-child relationship, which differs for a biological child, an adopted child, and a stepchild.
• Foster child under 26 — documentation of the caregiving relationship, including the certification OPM requires for foster children.
• Disabled child 26 or older — in OPM’s words, a medical certificate stating the child “is incapable of self-support because of a physical or mental disability that existed before he/she became age 26 and is expected to continue for more than one year.”

The last category trips people up, because it is the only one where a document must say something clinical rather than simply establish a relationship.

What happens if a family member cannot be verified?

OPM’s letter states that if a family member is determined to be ineligible, the enrollee must be notified promptly, and the enrollee must either submit a corrected election or the ineligible family member must be removed before the election is processed further.

That is the mechanism worth understanding. The consequence is not a fine — it is that the election does not complete. The addition does not take effect, and processing stops until the record is corrected. Where a determination goes against a family member, the enrollee is notified and generally has 60 days to request reconsideration from the employing office or OPM, per the framework used in earlier verification guidance. That decision is final.

When is Open Season?

FEDweek reported in August 2026 that this year’s Open Season will run November 9 through December 14. OPM has not posted official confirmation; its Open Season page still points forward to November 2026 without dates, and OPM has historically confirmed in early to mid October. Treat November 9 as reported rather than final until OPM publishes it. Whenever the window opens, FEHB Open Season verification applies to every election made inside it in which a family member is newly added.

OPM also sent agencies a readiness survey with BAL 26-202, due July 31, 2026. The letter says responses “will be used to inform any supplementary guidance OPM may issue before Open Season begins” — so further instructions are possible.

Key takeaways

• Beginning with Open Season for plan year 2027, employing offices must verify 100 percent of elections adding a family member (source: OPM BAL 26-202, July 15, 2026).
• The requirement comes from the FEHB Protection Act of 2025, Section 90101 of Public Law 119-21 (source: OPM).
• The prior standard was a 10 percent minimum review with 100 percent recommended (source: OPM BAL 24-201, 24-204).
• From July 4, 2026, all qualifying life events adding a family member must also be verified (source: OPM BAL 26-202).
• Open Season is reported as November 9 – December 14, 2026, not yet officially confirmed by OPM (source: FEDweek, August 2026).

Frequently asked questions

Does this affect family members already on my enrollment?
BAL 26-202 addresses elections in which a family member is added. Separate OPM activity on existing enrollments continues under the broader family member eligibility verification framework.

Does it apply to retirees?
The letter addresses employing offices and their Open Season election processing. Annuitant changes are handled by OPM’s Retirement Services, and OPM has not published separate instructions for annuitants under this letter.

Does switching plans without adding anyone trigger it?
The requirement is tied to elections in which a family member is added, not to plan changes generally. It also does not change the Self Plus One versus Self and Family tier decision.

Does this change the FEHB five-year rule?
No. Verification of family member eligibility and the five-year enrollment requirement for carrying FEHB into retirement are separate provisions.
