Kaiser FEHB Plans: Tiers, Premiums, and Drug Coverage

Kaiser Permanente’s FEHB plans give federal employees, retirees, and their families HMO coverage through Kaiser’s integrated care network, with three tiers available in most regions for the 2026 plan year: High Option, Standard Option, and the newer Prosper Option. Premiums sit toward the lower end of the FEHB marketplace, but you can only enroll if you live or work inside one of Kaiser’s geographic service areas.

Where You Can Enroll

Kaiser FEHB coverage is regional, not nationwide. Plans are offered in:

California — Northern California (including a Fresno-area market) and Southern California
Colorado — metropolitan Denver/Boulder, northern Colorado, and southern Colorado
Georgia
Hawaii
Maryland, Virginia, and Washington, D.C., including metropolitan Baltimore, Montgomery County, Prince George’s County, and portions of Calvert, Charles, and Frederick counties
Oregon and Washington
Washington State, including parts of northern Idaho under the Washington Core plan

You have to live or work in the designated service area for the specific plan you pick. Kaiser’s FEHB site has a zip code tool to confirm your address falls inside a covered area before you enroll.¹

The Three Plan Tiers

The tiers differ enough that picking the right one can mean hundreds or thousands of dollars a year depending on how much care you actually use.

High Option

No annual deductible. Copays are the lowest of the three: $15 for a primary care visit, $25 for a specialist, $15 for urgent care, and $100 for the ER. The out-of-pocket maximum is $3,000 per person, with a family cap of twice that. Prescriptions run $10 generic, $40 preferred brand, and $100 specialty.²

Standard Option

Lower premiums, higher point-of-care costs. There’s a $100 annual deductible and a $4,100 out-of-pocket maximum. Primary care visits are $30, specialists $40. ER care is $150 with the deductible applied. Inpatient hospital stays run $500 versus $250 under the High Option. Drugs are $15 generic, $50 brand, $150 specialty.²

Prosper Option

Prosper is the newest and lowest-premium tier, expanded to several regions for 2026, including Fresno, California, for the first time.³ It trades lower premiums for higher out-of-pocket exposure. In Northern California, Prosper has a $500 individual deductible ($1,000 family) and an out-of-pocket maximum of $6,600 per person ($13,200 per family). Primary care is $25, specialists $35, and many hospital and diagnostic services carry 20% coinsurance instead of flat copays. Generics stay at $15, but preferred brand and specialty drugs jump to $60 and $200.⁴

What You’ll Pay Per Paycheck in 2026

Premium rates vary by region. Two of the larger markets show the range.

Northern California, biweekly enrollee share:

High Option: $198.93 (Self Only), $538.93 (Self Plus One), $472.07 (Self and Family)
Standard Option: $110.42 (Self Only), $307.18 (Self Plus One), $254.59 (Self and Family)
Prosper: $81.77 (Self Only), $191.34 (Self Plus One), $191.34 (Self and Family)

⁵

Mid-Atlantic and D.C. area, biweekly enrollee share:

High Option: $144.27 (Self Only), $367.58 (Self Plus One), $300.72 (Self and Family)
Standard Option: $94.31 (Self Only), $216.93 (Self Plus One), $216.93 (Self and Family)
Prosper: $57.83 (Self Only), $138.16 (Self Plus One), $162.70 (Self and Family)

⁶

The government contribution covers the lesser of 75% of the total premium or 72% of the weighted average across all FEHB plans. In 2026, 66 of 132 FEHB plans receive the full 75% government share.⁷

Services Covered at No Cost

All three Kaiser FEHB tiers cover certain care with no copay or coinsurance. That includes telehealth visits (video, phone, or email), preventive care, routine prenatal and postpartum visits, and birthing doula services covering one initial visit and up to eight prenatal or postpartum visits.² Tobacco cessation medications, women’s contraceptives, and other drugs classified as preventive under the Affordable Care Act are also generally covered at no cost.⁸

Prescription Drugs

Kaiser manages prescriptions through a formulary, a tiered list of approved drugs maintained by its Pharmacy and Therapeutics Committee. The list changes throughout the year and is posted at kp.org/formulary.⁸

Copays vary by plan tier and by whether a drug is generic, preferred brand, non-preferred, or specialty. In Colorado, a 30-day supply of a generic drug costs $15 across all three tiers, while specialty drugs range from $150 under the High Option to $325 under Prosper.⁸ In the Mid-Atlantic region, filling a prescription at a Kaiser plan pharmacy costs less than at an affiliated network pharmacy, and mail order is the cheapest path: two copays for up to a 90-day supply of maintenance drugs.⁹

Some drugs require prior authorization, step therapy (trying a first-line drug before a costlier alternative is covered), or come with quantity limits. Drugs off the formulary are classified as non-preferred and carry higher cost-sharing, or may need a medical-necessity exception.¹⁰

GLP-1 Weight-Loss Drugs

Kaiser FEHB plans cover GLP-1 medications like semaglutide and tirzepatide for weight management, but the rules are strict. You pay 50% coinsurance. Prior authorization requires a baseline BMI of at least 27 with a weight-related comorbidity, documented failure of other weight-management medications over at least three months, and enrollment in a lifestyle and behavioral intervention program. You have to attend monthly in-office weigh-ins and attest to following a reduced-calorie diet and exercise regimen. Initial approval lasts three to six months, with reassessment after three months.¹¹

Care When You Travel or Move

Because Kaiser is an HMO, out-of-area care is limited. Emergency and urgent care are covered anywhere in the world without prior approval. Call 911 or go to the nearest ER, then call Kaiser’s Away from Home Travel Line at 951-268-3900 once you’re stable. Any care after your emergency condition is stabilized needs Kaiser’s approval to remain covered.¹²

For non-emergencies, Kaiser’s visiting member program lets you receive care in other Kaiser service areas after calling the travel line for a temporary medical record number. Routine care outside Kaiser service areas is not covered, and outpatient follow-up generally isn’t either unless it’s authorized or treated as urgent. FEHB members get a somewhat wider travel benefit: up to $1,200 per calendar year for outpatient follow-up and continuing care when you’re more than 100 miles from home.¹²

If you pay out of pocket for emergency or urgent care while traveling, you can submit for reimbursement. International care typically means paying the provider directly and filing after you get home, because Kaiser generally does not pay foreign providers directly.¹³

Retiree and Medicare Options

Kaiser offers a separate Medicare Advantage plan for FEHB-eligible retirees called Senior Advantage for Federal Members (HMO). To enroll, you need Medicare Part A and/or Part B and you have to live in a Kaiser Medicare plan service area.¹⁴

The most distinctive feature is a Medicare Part B premium reimbursement. Members enrolled in the High or Standard Option Senior Advantage 2 plans receive up to $250 per month, $3,000 per year, toward their Part B premium, paid from a health reimbursement account and not taxable. Spouses are eligible for the same reimbursement. It also covers late enrollment penalties and the income-related monthly adjustment amount higher-income retirees pay.¹⁵

Senior Advantage plans have no annual deductible, lower copays for most services and prescriptions, and an out-of-pocket maximum as low as $2,000 per person. They bundle hospital, medical, and prescription drug coverage into one plan and add hearing aids, eyewear, dental, a quarterly over-the-counter wellness product benefit of $70, the One Pass fitness program, non-emergency transportation, and meal delivery services.¹⁵

Retirees who don’t enroll in Senior Advantage are automatically placed in a Kaiser FEHB Medicare Prescription Drug Plan (PDP) at no additional premium. It keeps existing medical benefits in place while potentially lowering drug copays, and you can opt out during a designated notice period.¹⁴ OPM has determined Kaiser’s FEHB prescription drug coverage qualifies as creditable, so retirees who keep it will not face late enrollment penalties if they later join Medicare Part D.¹⁶

If a Claim Is Denied

Start with Kaiser. You have six months from an adverse determination to request internal reconsideration, submitted online at kp.org, by phone, or by mail. Include a copy of the denial, an explanation of why the decision was wrong based on the FEHB plan brochure, and any supporting medical documentation.¹⁷

If Kaiser upholds the denial, you can escalate to the Office of Personnel Management. The filing deadline is 90 days after Kaiser’s letter upholding the denial, or 120 days if Kaiser failed to respond within 30 days or asked for more information. OPM aims to decide within 60 days. If OPM’s ruling still leaves you unsatisfied, the last option is a lawsuit in federal court, which must be filed by December 31 of the third year after the disputed services were provided or the pre-authorization was denied.¹⁷

2026 Premium Trends and Open Season

The 2026 plan year is the second consecutive year of double-digit FEHB premium increases. Across the program, the average enrollee premium contribution rose 12.3%, a little below the prior year’s 13.5%. OPM attributed the continued increases to an aging federal workforce, higher rates of chronic conditions, and surging demand for prescription drugs, particularly GLP-1 weight-loss medications.³

Kaiser bucked the trend in some regions. The Kaiser High Option plan in Georgia (enrollment code F81) had the largest enrollee-share decrease of any FEHB plan for 2026, dropping 18% and saving enrollees roughly $727 over the year.⁷ The FEHB program overall shrank slightly, with 14 fewer plans available than the prior year.³

Open Season for 2026 ran from November 10 to December 8, 2025, with coverage changes taking effect January 25, 2026.⁷¹⁸ Outside Open Season, you can change enrollment within 60 days of a qualifying life event, such as becoming newly eligible or moving outside a plan’s service area.
