2027 FEHB Changes: GLP-1 Drug Coverage Rules and OPM’s Well Care Shift
2027 FEHB Changes: GLP-1 Drug Coverage Rules and OPM’s “Well Care” Shift
The Office of Personnel Management has issued its annual call letter to Federal Employees Health Benefits carriers for plan year 2027, and it is one of the most consequential pieces of FEHB guidance in years. The headline changes — new prerequisites for GLP-1 weight-loss drugs, an end to cash incentives for childhood vaccines, and a broad pivot toward “well care” and preventive medicine — are going to show up in your plan brochure during this fall’s Open Season.
If you are a federal employee approaching retirement, here is what is changing, what it means for your wallet, and the decisions you should be ready to make when Open Season opens this November.
What the OPM Call Letter Actually Does
Each spring, OPM sends a “call letter” to every FEHB carrier laying out its priorities for the upcoming plan year. Carriers then file their proposed benefits and premiums in response. The 2027 call letter signals a clear shift in how OPM wants federal health plans to handle obesity treatment, preventive care, mental health, and chronic disease management.
Federal retirees keep their FEHB coverage for life if they meet the five-year enrollment rule, so changes to FEHB plans affect both current employees and the more than 2 million federal annuitants enrolled in the program.
GLP-1 Drugs: Therapy Before the Prescription
The most talked-about provision in the 2027 call letter concerns GLP-1 medications — drugs like Wegovy, Zepbound, Ozempic, and Mounjaro that have rapidly become the most common weight-loss prescriptions in the country. OPM’s guidance asks carriers to require a course of behavioral therapy or lifestyle intervention before approving GLP-1 prescriptions for obesity.
The reasoning: these medications are extraordinarily expensive and a major driver of recent FEHB premium increases. OPM is also concerned that prescribing GLP-1s without addressing underlying behaviors creates lifetime dependence — the weight typically returns when the medication stops.
What This Means for You
If you are currently taking a GLP-1 for diabetes, your coverage is unlikely to change — diabetes indications are different from weight-loss indications. If you are taking one for weight loss, expect prior-authorization rules in 2027 that will require documented enrollment in an approved behavioral or nutritional program before the prescription is renewed.
If you are considering starting a GLP-1 in retirement, factor the new prerequisite into your planning. Federal retirees who are also enrolled in Medicare may have different coverage paths — see our guide to how Medicare and FEHB work together.
End of Cash Incentives for Childhood Vaccines
Several FEHB carriers have offered cash incentives or gift cards to families who keep their children up to date on the recommended vaccine schedule. The 2027 call letter ends that practice.
For most federal retirees this is a non-event — your covered children are likely past pediatric vaccination age. For employees still raising school-age children, it means the small bonus payments tied to well-child visits will disappear in 2027.
The “Well Care” Pivot
OPM is asking carriers to lean harder into preventive medicine, screening, and whole-person care. Expect to see expanded coverage for primary care visits, more aggressive coverage of chronic disease management programs, and stronger incentives to choose plans that emphasize prevention over reactive specialty care.
This is broadly good news for federal retirees. Preventive care visits are already covered with no copay under FEHB and Medicare’s preventive benefit, but the 2027 changes push carriers to actively design plans around primary care and screening rather than treating those services as cost centers.
Mental Health and Substance Use Coverage
The call letter continues a multi-year push to strengthen mental health parity in FEHB plans. Carriers are being asked to expand telehealth options for behavioral health, ensure adequate networks for psychiatry and therapy, and remove administrative barriers that have historically made mental health coverage harder to use than physical health coverage.
Federal retirees have used these benefits at rising rates over the past five years, and the trend in OPM guidance is to make access easier rather than harder.
What Will Premiums Do in 2027?
Honest answer: probably go up. FEHB premiums have risen every year for more than a decade, and prescription drug costs — particularly GLP-1s and specialty drugs — are the single biggest driver. The 2027 changes are partly aimed at slowing those increases by managing utilization. Whether they actually do is going to be the big question heading into Open Season.
The 2026 enrollee share for the standard option Self Plus One in the most popular FEHB plans ranges roughly from $300 to $450 per pay period. Federal retirees should plan for at least mid-single-digit percentage increases in 2027 as a working assumption until OPM publishes final premium data in late September or October.
Open Season Strategy for 2027
Open Season for 2027 plans will run mid-November through mid-December 2026. Federal employees and retirees who want to make a change should approach it as a real decision rather than a renewal default.
1. Compare GLP-1 Coverage Carefully
If anyone in your household uses or might use a GLP-1 medication, read the 2027 plan brochures carefully for prior-authorization language, behavioral-therapy requirements, and pharmacy tiers. Coverage details will vary substantially between carriers.
2. Look at Out-of-Pocket Maximums, Not Just Premiums
Federal retirees often default to whatever plan they had during their working years. The math frequently changes once you stop paying through pre-tax payroll deduction and start paying premiums in retired-from-payroll dollars. Our guide to FEHB premiums in retirement covers the math.
3. Decide on Your Medicare Strategy
If you are 65 or approaching 65, your FEHB and Medicare strategy may matter more than which FEHB plan you pick. Some FEHB plans offer Medicare reimbursement, reduced cost-sharing, or Part B premium subsidies for enrollees who also have Medicare. The combinations can be confusing — but they are worth getting right because the difference can be thousands of dollars per year.
4. Consider Whether You Still Need Self & Family
Many federal retirees stay on a Self & Family plan after their dependents are no longer covered. Switching to Self Plus One or Self Only at the right time can save several thousand dollars annually.
What to Do Right Now
You do not need to make any decisions today. The 2027 changes do not take effect until January 1, 2027, and the actual plan brochures will not be published until October 2026. But this is the right moment to:
- Make a list of any prescription drugs you take regularly, particularly GLP-1s, specialty drugs, and brand-name medications without generic alternatives.
- Review your 2026 medical and pharmacy claims to see what you actually used.
- If you are within five years of retirement, confirm you will meet the five-year FEHB enrollment requirement so you can carry your coverage into retirement.
- If you are 64 or older, start thinking about your Medicare Part A and Part B enrollment timing.
The Bigger Picture
The 2027 call letter is part of a broader OPM effort to reshape FEHB into a more value-driven, prevention-focused program. Whether the changes save the program money in the long run is debatable, but the direction is unmistakable. Federal employees who plan ahead for these shifts — particularly the GLP-1 changes and the continued push for Medicare integration — will navigate Open Season far more effectively than those who renew on autopilot.
FEHB is one of the most valuable benefits federal employees earn. It is also one of the most complex, especially as you transition from working coverage to retired coverage to Medicare-coordinated coverage. We walk through the full FEHB-to-Medicare transition at every Fed Pilot workshop because it is the single area where federal retirees most often leave money on the table.
