Quick answer
GEHA is a fee-for-service plan under the Federal Employees Health Benefits Program, and its 2026 plan brochure covers mental health and substance use disorder services including detoxification, inpatient care, and residential treatment centers. The catch is precertification: GEHA requires it for all inpatient stays, residential treatment centers, and intensive day treatment, with a financial penalty for skipping it.
For federal employees and retirees, the rehab question comes with an unusual amount of published detail - GEHA has to print its benefits in a public OPM brochure, and the 2026 edition says more about substance use treatment than most commercial plans ever will. The short answer: GEHA plans cover substance use disorder treatment, including detoxification, inpatient care, and residential treatment centers, but planned admissions to higher levels of care require precertification first, and skipping it triggers a financial penalty that never falls off. Here is how it works and what to check for your option.
What GEHA is, and why FEHB rules shape the benefit
GEHA - the Government Employees Health Association - administers fee-for-service plans with a preferred provider organization under contract (CS 1063) with the U.S. Office of Personnel Management, as the 2026 brochure states. OPM negotiates benefits and rates with each FEHB plan annually, and the brochure notes GEHA holds Health Plan Accreditation from the Accreditation Association for Ambulatory Health Care. Federal employees and annuitants enroll with a Standard Form 2809.
That federal framework matters for treatment coverage. OPM directed FEHB plans to provide network parity for mental health and substance abuse care back in 2001, requiring coverage for treatment of all diagnostic categories in the DSM to the extent services are in authorized treatment plans, delivered under standard protocols, and medically necessary. OPM's carrier letters require FEHB carriers to comply with the Mental Health Parity and Addiction Equity Act, including the 2021 amendments on non-quantitative treatment limitations. So the behavioral benefits you are asking about sit inside a longer federal parity story than most commercial coverage.
What the 2026 brochure covers for substance use disorder
GEHA's Section 5(e), Mental Health and Substance Use Disorder Benefits, lists the covered services that matter here:
- Diagnosis and treatment of substance use disorders, including detoxification, treatment, and counseling
- Diagnostic evaluation, crisis intervention and stabilization, and medication evaluation and management
- Individual, group, or in-home therapy visits, and professional charges for intensive outpatient treatment
- Inpatient services provided and billed by a hospital or other covered facility, limited for medically necessary treatment to a hospital and/or residential treatment center
- Partial hospitalization and other intensive day treatment programs, with preauthorization
- Behavioral health telehealth, including substance use disorder counseling, through the plan's telehealth partner
Cost sharing follows parity in the brochure's own words: for professional mental health and substance use disorder services, "your cost-sharing responsibilities are no greater than for other illnesses or conditions." Exact numbers depend on your option - the HDHP applies its calendar-year deductible first ($1,800 Self Only / $3,600 Self Plus One or Self and Family in-network for 2026), then coinsurance; other options use copays. The 2026 benefits guide advertises $0 telehealth mental health visits and, for some options, low mental health office visit copays.
The precertification rule that catches people
GEHA's brochure puts this in capital letters, and for good reason: you must get precertification for all inpatient stays, residential treatment centers, and intensive day treatment unless it is a medical emergency. Failure to precertify results in a financial penalty, and penalties are not subject to the catastrophic limit - meaning it is extra money on top of everything else.
Outpatient services need attention too: intensive day treatment (partial hospital and intensive outpatient), applied behavioral analysis, and psychological testing must be precertified as well.
Practical translation: if a treatment center is arranging your admission, confirm in writing that it has contacted GEHA and received the precertification for your level of care. If you are arranging it yourself, call GEHA Customer Care at 800-821-6136 before admission. An emergency admission is different - the brochure waives the requirement when care is due to a medical emergency - but planned rehab admissions never fall under that exception.
Exclusions worth knowing before you choose a program
Not everything that calls itself recovery care is covered. GEHA's Section 5(e) states that services rendered or billed by schools, halfway houses, sober homes, or their staff are not covered, nor are pastoral or educational counseling and services from non-covered providers. Residential treatment coverage attaches only to facilities meeting the plan's residential treatment center definition - including an individualized treatment plan, 24-hour registered nursing, and required patient records.
That matters when someone suggests sober living "while the insurance sorts itself out." It will not be a GEHA claim. Ask what the facility bills as, and confirm that billing classification is covered under your option.
Your rights if a request is denied
FEHB parity protections mean the criteria behind a medical necessity decision are not a black box. SAMHSA's Know Your Rights guide explains how to appeal, how to request the criteria used, and what your plan must disclose. GEHA's brochure also directs members to its published medical and payment policies at geha.com/Provider-Policies. Appeal timelines matter, so start quickly and keep copies of everything.
For help finding treatment and checking your GEHA benefits, call (800) 653-9376. The call is free to you, the referral service is paid for by treatment providers, and there is no judgment waiting on the line. SAMHSA's National Helpline (1-800-662-4357) is a free, confidential alternative open around the clock.
If stopping alcohol or benzodiazepines suddenly could be dangerous for you, do not stop on your own - withdrawal from these substances needs medical supervision. In an emergency, call 911. In a crisis, call or text 988.
Questions about Geha Coverage
Does GEHA cover detoxification and rehab?
Yes. GEHA's 2026 FEHB plan brochure lists diagnosis and treatment of substance use disorders - including detoxification, treatment, and counseling - among covered professional services, along with inpatient hospital stays and residential treatment centers when precertified and medically necessary.
What happens if I enter rehab without precertification?
GEHA's brochure states you must get precertification for all inpatient stays, residential treatment centers, and intensive day treatment unless it is a medical emergency - and that failure to precertify will result in a financial penalty, which is not subject to the plan's catastrophic limit. Call GEHA at 800-821-6136 before a planned admission.
How does GEHA's cost sharing compare to other illnesses?
GEHA's brochure says your cost-sharing responsibilities for mental health and substance use disorder professional services are no greater than for other illnesses or conditions. Specific figures depend on which GEHA option you hold - High, Standard, HDHP, or Elevate - and whether providers are in-network.
Is telehealth counseling for substance use covered?
Yes. GEHA's 2026 materials cover behavioral health telehealth including mental health and substance use disorder counseling through the plan's telehealth partner at no member cost, and the benefits guide advertises unlimited $0 telehealth visits including mental health with MDLIVE.
Are sober living homes covered by GEHA?
No. GEHA's brochure excludes services rendered or billed by schools, halfway houses, sober homes, or their staff, and residential treatment coverage applies only to facilities that qualify as residential treatment centers under the plan's definitions.
