Common Questions About Care at University Hospital/Stony Brook ELIH
Records on file indicate this program accepts both Medicaid and Medicare. Specific eligibility rules, covered services, and authorization steps differ by state and plan tier. The admissions team can run a benefits check and walk through any cost-share before you schedule.
Medication-assisted treatment (MAT) is offered with Buprenorphine used in Treatment, Naltrexone used in Treatment. These FDA-approved medications ease withdrawal and reduce craving while clients begin therapy. The treating physician sets dosing and the long-term plan based on an individual clinical assessment.
Outpatient care is designed around real life. Sessions are scheduled in evenings, mornings, or partial-day blocks so clients can keep up with work, school, or caregiving while building recovery skills they can apply the same week.
Yes, this site treats adolescents in an age-appropriate program. Teen tracks typically weave in family sessions, academic continuity supports, and developmentally tailored therapy. Admissions can walk parents and guardians through consent requirements and what a typical week of programming covers.
Gender-responsive programming gives women space to work on trauma, relationships, and parenting in a setting tailored to their needs. Some sites coordinate childcare or family housing alongside treatment. If pregnancy or postpartum care is part of the picture, ask admissions about pregnancy-safe protocols.
Aftercare planning starts well before discharge. Typical paths include step-down to outpatient services, referrals to sober-living homes, alumni group meetings, and warm hand-offs to community recovery resources. Many programs maintain alumni networks so peer support and accountability continue once formal treatment is complete.
Yes — both family counseling and marital or couples counseling are offered. Sessions are sequenced through the program and continue into aftercare. Working with relatives helps rebuild trust, name healthy boundaries, and prepare the home environment so it can hold up the recovery work after discharge.
Yes, this program is hosted inside a general hospital, so medical complications tied to withdrawal or co-existing conditions can be managed in-house. That matters most for clients detoxing from alcohol, benzodiazepines, or opioids who also need medical oversight for other diagnoses during the acute phase of care.
Total cost depends on program length, level of care, and the specific services involved. Most sites can set up payment plans or point to outside financing partners. A confidential call to admissions gets you a tailored cost estimate for your situation rather than a guess based on a generic price sheet.
This site offers general information about addiction treatment centers. It is not a substitute for professional medical advice, diagnosis, or treatment.
