Geisinger Coverage for Rehab and Addiction Treatment

If you carry a Geisinger card and you or someone you love needs drug or alcohol treatment, the good news is that Geisinger is unusual among insurers: it runs some of the treatment itself. Its health plan covers outpatient counseling, medication-assisted treatment, and inpatient and residential care, and its own Marworth Treatment Center in Waverly, Pennsylvania provides 24/7 detox and residential treatment. The rules to know are simple - most outpatient care needs no referral, inpatient admissions need prior authorization - and knowing them up front keeps a hard week from getting harder.

The plan lines, briefly

Geisinger Health Plan is part of Geisinger, an integrated health care delivery and coverage organization in central and northeastern Pennsylvania (Risant Health is its parent organization). Its consumer plan lines include:

• Geisinger Gold - Medicare Advantage HMO, PPO, and HMO D-SNP plans.
• Marketplace plans - individual ACA coverage for people who do not get insurance through work.
• GHP Family - Pennsylvania Medical Assistance (Medicaid) managed care.
• GHP Kids - Pennsylvania's CHIP program for uninsured children up to age 19.

Each line covers behavioral health, but the mechanics differ - Medicare members work through the plan's own utilization review, while GHP Family members' mental health and substance use services are provided through county behavioral health managed care organizations (BH-MCOs) overseen by the Pennsylvania Department of Human Services' Office of Mental Health and Substance Abuse Services (OMHSAS). If you are on GHP Family, Geisinger's coverage page tells you to search for the BH-MCO that serves your county.

What the Medicare Evidence of Coverage says

The 2026 Geisinger Gold Evidence of Coverage spells out the covered categories in black and white: mental health services, substance disorder services, and opioid treatment program services - the last covering FDA-approved medication-assisted treatment, dispensing, substance use counseling, individual and group therapy, toxicology testing, intake activities, and periodic assessments through an Opioid Treatment Program. The same document lists telehealth categories that matter here: individual substance use disorder telehealth services, group substance use disorder telehealth services, mental health and SUD urgent care telehealth, and telehealth for members with a substance use disorder or co-occurring mental health disorder regardless of location.

Outpatient SUD services are covered when delivered by a state-licensed psychiatrist or doctor, clinical psychologist, clinical social worker, clinical nurse specialist, nurse practitioner, physician assistant, or other Medicare-qualified SUD professional as allowed under state law. That roster matters when you are choosing a counselor - licensure type can affect what a plan covers.

The referral and prior authorization rules

Geisinger's member guidance is unusually clear on this point, and it is worth quoting the shape of it rather than paraphrasing loosely:

• Most members do not need a referral to access a participating mental health provider or facility for outpatient services, and you may seek care from a participating alcohol or other substance dependency provider for outpatient and inpatient SUD services without first seeing your primary care provider.
• Any non-routine outpatient services or any inpatient services require a prior authorization. The plan's provider-facing prior authorization list confirms behavioral health indications have carried prior auth requirements across Medicare, Medicaid, and FEHBP products for years, with a separate outpatient prior authorization form and a behavioral health services review form covering inpatient admissions of any type and partial hospitalization.
• The number to call for network status and authorization questions is the Behavioral Health Care Connector team at 888-839-7972 (TTY: 711), staffed Monday through Friday, 8 a.m. to 5 p.m.

That split - open access to routine outpatient care, authorization gate on inpatient care - is the single most useful thing to know before you call a facility.

Medication-assisted treatment and Marworth

Geisinger's own clinical policy for medication-assisted treatment (MP373) describes the plan's expectations for Opioid Use Disorder Centers of Excellence and non-COE MAT providers, aligned with Pennsylvania Department of Human Services requirements. The policy expects member engagement with care management at least monthly, a detailed substance use history, withdrawal-potential assessment (for example, the Clinical Opiate Withdrawal Scale), and an assessment of the role substance use plays in the member's life. It also defines the medical-necessity bar for inpatient levels: a member requires acute care as an inpatient when they cannot receive safe or adequate care as an outpatient.

For members who want Geisinger's own programs, the member-facing behavioral health page lists:

• Marworth Treatment Center (Waverly, PA) - 24/7 detox and residential treatment for adults 18 and older, a three-day-a-week intensive outpatient program, and in-person or telehealth outpatient counseling. Geisinger publishes 800-442-7722 as the number to start there.
• MAT at Geisinger clinic locations - Bloomsburg, Scranton, Wilkes-Barre, Williamsport, Waverly, and Lewistown.
• Other in-network options - substance use therapy, medication management, and inpatient, residential, partial hospital, and intensive outpatient programs across the network.

What to do next

If you are weighing a program, call the plan first (888-839-7972) and ask two questions: is the facility in-network, and does this admission require prior authorization. Get both answers before anyone signs admission paperwork. If you would rather have someone else make those calls, that is what we are here for - call or text (800) 653-9376 any time and we will work through the coverage questions with you.

If you are in immediate danger, call 911. If you need to talk with someone about a crisis tonight, call or text 988.
