FEHB GLP-1 Coverage 2027: What the New IBT Rule Means
FEHB GLP-1 coverage in 2027 requires documented intensive behavioral therapy before and during treatment. What benefits offices should tell employees.
By Shawn McCoy7 min read
FEHB GLP-1 coverage in 2027 comes with a new condition. Every FEHB and PSHB carrier will require documented participation in an evidence-based intensive behavioral therapy (IBT) program, both before and during treatment with anti-obesity medications. Plans will still cover at least one GLP-1 anti-obesity medication and at least two oral options. Employees who take, or plan to start, these medications should read their 2027 plan brochure during open season, November 9 through December 14, 2026. Benefits offices should expect questions.
What OPM announced about FEHB GLP-1 coverage 2027
The source is OPM's 2026 Federal Benefits Open Season Highlights for Plan Year 2027. Under the heading "Prevention and Treatment of Obesity," OPM says:
- Plans will continue to cover at least one GLP-1 anti-obesity medication and at least two oral anti-obesity medications.
- For 2027, all FEHB and PSHB carriers will require documented participation in an evidence-based IBT program before and during treatment with anti-obesity medications.
- Plans are expected to cover specified individual and group IBT and medical nutrition therapy services, including 12 to 22 IBT sessions per year depending on progress.
- Carriers must coordinate these services with any medication and metabolic surgery criteria.
- Plans must cover qualifying IBT programs for children and adolescents ages six and older with a BMI above the 95th percentile.
- Qualifying programs provide 26 or more contact hours over three to 12 months and track participation, completion, weight change and specified cardiometabolic outcomes.
Why OPM is adding the requirement
OPM ties 2027 premium growth partly to prescription drug costs. The highlights name higher spending on GLP-1s, specialty drugs and other high-cost therapies as one of the main drivers. The average FEHB premium is rising 9.3%, and the average enrollee share is rising 10.9%.
The IBT requirement pairs medication with structured lifestyle support. For enrollees, the practical effect is an extra step: they must show participation in a qualifying program to start or continue treatment.
Who is affected
Employees already on an anti-obesity medication
OPM's language covers participation "prior to and during" treatment. Employees already using an anti-obesity medication should not assume their 2027 coverage will continue unchanged. They should check their plan's 2027 brochure, or call the plan, to learn how it will document IBT participation for current users.
Employees thinking about starting treatment
New users will need to complete or enroll in a qualifying IBT program before treatment. Plans will describe which programs qualify and how sessions are covered.
Families with children or teens
The children's coverage rule is new for many families. Plans must cover qualifying IBT programs for children and adolescents ages six and older with a BMI above the 95th percentile.
Postal employees and annuitants
The rule applies to PSHB as well as FEHB, so postal enrollees face the same requirement.
What benefits offices should, and should not, say
Benefits staff are not clinicians, and plan rules differ. A good message explains the change and points people to the plan.
Do say:
- Every FEHB and PSHB plan will require documented IBT participation before and during anti-obesity medication treatment in 2027.
- Plans must still cover at least one GLP-1 and two oral anti-obesity medications.
- Check your plan's 2027 brochure and formulary during open season.
- If your plan's approach does not work for you, open season is the time to compare.
Do not:
- Recommend a specific medication or plan.
- Promise that a particular drug will be covered.
- Interpret medical criteria such as BMI thresholds for an individual.
Questions employees are likely to ask
"Will my GLP-1 be covered next year?" Every plan must cover at least one GLP-1 anti-obesity medication, but not necessarily every brand. Check the 2027 formulary for your plan, and compare formularies if your medication is not listed.
"What counts as intensive behavioral therapy?" OPM describes evidence-based programs that may be individual or group sessions, along with medical nutrition therapy. Your plan defines which programs qualify and how to document participation.
"How many sessions will I need?" OPM expects plans to cover 12 to 22 IBT sessions per year depending on progress. The exact number for an individual depends on the plan's criteria.
"Is this only for weight loss medications?" OPM's language refers to treatment with anti-obesity medications. People who take a GLP-1 for another condition, such as diabetes, should ask their plan how the rule applies to them.
"Will I pay for the sessions?" Plans are expected to cover specified IBT services. Cost sharing, network rules and any visit limits will be in the plan brochure.
"What about surgery?" OPM says carriers must coordinate IBT with medication and metabolic surgery criteria, so people considering bariatric surgery should also read the 2027 brochure.
Other 2027 health benefit changes to mention
The IBT rule is one of several plan year 2027 changes in OPM's highlights. Plans have been encouraged to include preconception screening and education for those seeking fertility care. All FEHB and PSHB enrollees will receive in-network coverage, without cost sharing, for perinatal depression preventive interventions recommended by the U.S. Preventive Services Task Force. Plans have also expanded participatory wellness incentives to all members. Coverage of digital therapeutics varies by plan. A short "what's new" summary that lists these changes, with a pointer to plan brochures, helps employees see why reading the brochure is worth the time.
A timeline for employees on treatment
Employees who use an anti-obesity medication have a few weeks to get ready. A simple sequence helps:
- Now through early December: Read your plan's 2027 brochure section on obesity treatment and the formulary entry for your medication.
- Before December 14: If the plan's approach or formulary does not fit, compare other plans during open season. After open season closes, most people cannot change plans until next year unless they have a qualifying life event.
- December: Ask your prescriber about qualifying IBT programs and how participation will be documented.
- January: Confirm with your plan, under your 2027 coverage, that any prior authorization is in place before your next refill.
Non-postal employees who change plans should remember that their new FEHB coverage begins January 10, 2027. Refills before that date run through the current plan.
A sample note for employees
For 2027, all FEHB and PSHB plans will require documented participation in an intensive behavioral therapy program before and during treatment with anti-obesity medications, including GLP-1s. Plans will cover 12 to 22 therapy sessions a year depending on progress. If you take or plan to start one of these medications, review your plan's 2027 brochure and formulary before Open Season ends on December 14, 2026, and call your plan with questions.
How this fits into open season comparisons
The IBT rule applies across all plans, so switching plans will not avoid it. What differs is the detail: which GLP-1 is on the formulary, the drug tier and copay, prior authorization criteria, and which IBT programs are in network. Employees should compare those details using plan brochures, available through OPM's open season page.
Other 2027 changes also deserve a look, including family member documentation and terminating plans. Our guide to FEHB terminating plans for 2027 and our open season communications checklist can help you plan the rest of the season.
Supporting employees beyond enrollment
Health decisions and money decisions are connected. A 10.9% average increase in the enrollee share of premium affects take-home pay, and so do prescription copays. FEBA's financial wellness programs help employees see the whole picture, and our agency briefings explain plan year changes in plain language.
