A spouse or a stepchild added to a federal health plan during this year’s open season will not be enrolled on a promise. Anyone adding a family member to Federal Employees Health Benefits coverage, known as FEHB, must submit supporting documents proving that person is eligible, the Office of Personnel Management says. The requirement begins with the plan year 2027 open season, which opens November 9.
The law behind the paperwork rule
The rule traces to the FEHB Protection Act of 2025, Section 90101 of Public Law 119-21, signed July 4, 2025. OPM’s open season highlights for plan year 2027 say anyone adding a family member during Open Season 2027 “must submit supporting documentation” to verify eligibility.
The window is November 9 to December 14, 2026. The highlights apply the requirement to FEHB and to the Postal Service Health Benefits program. They also list annuitants among the groups whose open season changes take effect January 1, 2027, so retirees adding a spouse or dependent child fall under the same open season.
OPM’s pages do not describe a separate route for annuitants. They point enrollees to OPM.gov and to the benefits officer at the employing office. A retiree who plans to add someone should expect to need the same proof that active employees will.

Which family members count, and which need proof
OPM’s family member eligibility verification page names three groups that can be covered. They are a spouse, children under 26 including biological, adopted, step and foster children, and a child age 26 or older whom the employing office finds incapable of self-support because of a disability that began before age 26.
Verification applies whenever a family member is added. That includes the initial opportunity to enroll, open season and a qualifying life event such as a marriage or birth. Until now, agencies had been required to review only a minimum of 10% of open season additions, with 100% recommended, according to OPM’s guidance letters.
That has changed. Benefits Administration Letter 26-202, dated July 15, says full verification of added family members takes effect with the plan year 2027 open season. Qualifying life events that add a family member have been checked at 100% since July 4, 2026.
What happens if the proof falls short
Under the letter, employing offices must request and evaluate proof-of-relationship documents for each open season election that adds a family member. An enrollment cannot be finalized until eligibility is verified. If a relative does not qualify, the enrollee is notified and must either submit a corrected election or remove that person before the election moves forward.
Checks can also happen after coverage starts. OPM’s page says that if verification is completed later and the family member is ineligible, the employing office removes that person under federal regulation 5 CFR 890.308(f). A spouse or child dropped midyear would lose coverage.
OPM tells agencies to make every effort to verify new family members within 30 days of receiving acceptable documents. Proof accepted earlier in the same plan year generally does not have to be sent again. An employee who makes several changes during open season is checked on the final election, and earlier verification in the same open season does not need to be repeated.
Carriers carry part of the load. OPM’s page says that before adding a family member to an existing Self and Family enrollment, carriers must require proof of eligibility. Existing carrier processes continue for additions that do not change premiums.
The enrollment type matters because it moves the premium. OPM’s open season page notes that for some plans the enrollee share of premiums for Self Plus One may be higher than for Self and Family. An enrollee adding one person should compare both options before filing the form and the documents together.
Documents, deadlines and effective dates
OPM’s pages do not list which document proves which relationship. The highlights send enrollees to OPM.gov or their employing office benefits officer for that, and OPM’s open season page links to the verification section. Anyone adding a person should ask for the list before November 9.
Questions about uploading documents go to the employing office’s shared service provider, not to OPM, which does not run those enrollment systems. Verification documents become enrollment records and are filed in the employee’s official personnel folder. Existing retention rules still apply.
Dates drive the timing. Open season ends at 11:59 p.m. on December 14, 2026. Changes for annuitants and PSHB enrollees take effect January 1, 2027, and changes for most FEHB employees outside the Postal Service take effect January 10, 2027.
A document that is missing on December 14 is the real risk. Because enrollment cannot be finalized until eligibility is verified, a family member whose proof is not in hand or accepted in time may not be added in this open season. OPM’s pages do not say what happens to an election that is still pending when the window closes.
The open question for a retiree is what to gather now. The covered groups run from a spouse to a disabled adult child, and the disabled-child category depends on a finding by the employing office. Starting the paperwork in October leaves room to fix a gap before the deadline.
Nine FEHB plans are terminating for 2027, and their enrollees default to Compass Rose Standard unless they pick another plan. Anyone in that group is already making an open season election, and adding a spouse or child to the new plan at the same time means the document check applies to the same filing.
Have your documents ready before December 14?
A family member who cannot be verified by the close of open season may not be added for 2027, and a rushed upload in the last week leaves no time to fix a missing page. For households already stretched by premium increases, an uncovered spouse or child is a bill nobody planned for.
The family-document hunt is one piece of a bigger household-cost job, and The Benefits Checklist finishes the rest. It scans 11 benefit programs retirees often miss, including Medicare Savings Programs, Extra Help and SNAP, and lists the 2026 income limits and a 50-state phone directory. It does not cover FEHB enrollment itself.
