About Regional Health Systems
Regional Health Systems is a Joint Commission-accredited substance use treatment facility located at 8555 Taft Street in Merrillville, Indiana, serving the Lake County region of Northwest Indiana. Operated under the mission of being a family’s partner in health, the center provides comprehensive addiction treatment as part of a broader behavioral and primary health care organization — one of the few in the area combining addictions treatment with mental health care under a single accredited system.
The facility’s levels of care span the full treatment continuum, beginning with medical detox for individuals who require supervised withdrawal management before transitioning to longer-term care. Following detox, patients can step into residential treatment for structured, round-the-clock support, or access outpatient and intensive outpatient (IOP) programming as their clinical needs dictate. This range of levels of care means patients can move through treatment within a single system rather than being handed off to an unrelated provider.
Clinical care at Regional Health Systems incorporates Cognitive Behavioral Therapy (CBT) and addresses co-occurring disorders and dual diagnosis — a critical capability for individuals whose substance use is intertwined with mental health conditions. The facility operates Monday through Thursday from 8:30 a.m. to 8:00 p.m. and Friday from 8:30 a.m. to 5:00 p.m., providing extended weekday access that many outpatient-only programs do not offer.
Regional Health Systems serves a notably broad population, with dedicated programming for pregnant women and accommodations for individuals who are deaf or hard of hearing — specialized access points that set it apart from most local treatment providers. Financially, the center accepts Medicaid, Medicare, TRICARE, private insurance, self-pay, and offers sliding scale fees and financial assistance, removing common barriers to entering medically supervised detox and addiction treatment.
