Common Questions About Care at Saint Johns Riverside Hospital
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.
The young-adult track focuses on the challenges specific to this stage of life — peer dynamics, identity formation, and the move into independent living. Programming usually pairs traditional addiction therapy with career counseling and practical life-skills work.
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.
Trauma-informed practice runs through the program. Qualifying clients can access EMDR, somatic experiencing, and trauma-focused CBT alongside the standard clinical track. Staff are trained to recognize trauma responses and to keep the therapeutic environment physically and emotionally safe.
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.
Family counseling runs alongside the primary clinical program. Relatives are invited into education sessions, communication-skills practice, and discharge planning so the family system actively supports recovery rather than undermining it. CRAFT principles can inform how loved ones engage with the person in treatment.
Yes, this program addresses behavioral or process addictions in addition to substance use disorders. The clinical model targets the shared mechanisms — craving, reward dysregulation, avoidance — and then tailors the relapse-prevention work to the specific behavior the client is working to change.
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.
Transportation assistance is part of the program — appointments, group sessions, and admissions logistics can be supported. Eligibility and service radius depend on the track: outpatient ride support, residential intake pickups, and aftercare appointment transport are typically handled through separate pathways. Admissions can confirm what fits your situation when you call.
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.
