About

About Three Rivers Behavioral Health

Three Rivers Behavioral Health is a behavioral health hospital located at 2900 Sunset Blvd in West Columbia, South Carolina, serving individuals across the state who need structured, medically supervised care for substance use disorders, chemical dependency, psychiatric disorders, and trauma. The facility operates 24 hours a day and maintains an admissions line — (803) 796-9911 — staffed around the clock, which matters when families or individuals are making same-day decisions about care. Its position in Lexington County places it within reach of the broader Columbia metro area and surrounding South Carolina communities.

The facility’s levels of care span a wide clinical range. Medical detoxification is available for adults managing withdrawal from chemical dependency, supported within a hospital setting that also offers adult inpatient rehabilitation and acute psychiatric services. Beyond those higher-acuity programs, Three Rivers provides a Partial Hospitalization Program, an Intensive Outpatient Program, and a Virtual Intensive Outpatient Program for those who require structured treatment without full inpatient admission. Both inpatient and outpatient tracks exist for adolescents ages 11 through 17, as well as for adults — making it one of the few behavioral health hospitals in South Carolina offering that full a continuum under one roof.

Three Rivers Behavioral Health treats substance use disorders and chemical dependency alongside psychiatric disorders and trauma, reflecting a dual-focus model grounded in the confirmed scope of the hospital’s clinical programs. The facility’s behavioral health hospital designation — rather than a standalone detox clinic or freestanding rehab — means medical detox occurs within an environment that can also address co-occurring psychiatric conditions. That structural distinction is relevant for individuals whose withdrawal picture is complicated by mental health symptoms.

Three Rivers serves adults, adolescents between the ages of 11 and 17, and military personnel and first responders — and it accepts TRICARE, the federal insurance program covering active-duty service members, veterans, and their dependents. For military families in South Carolina navigating substance use or psychiatric crises, that combination of TRICARE acceptance and 24-hour availability is a practical differentiator. The facility’s breadth of programming — from medical detox through virtual outpatient — means that patients may be able to step down through levels of care without transferring to an entirely different provider.

  • Medical detoxification available within a full behavioral health hospital — not a standalone detox clinic — supporting cases where withdrawal intersects with psychiatric conditions
  • 24-hour admissions and operations, enabling same-day intake decisions for individuals and families in crisis
  • TRICARE accepted, directly serving military personnel, veterans, and first responders across South Carolina
  • One of the few South Carolina facilities offering both adolescent (ages 11–17) and adult inpatient and outpatient tracks under the same roof
  • Virtual Intensive Outpatient Program available alongside in-person PHP and IOP, providing step-down flexibility after inpatient detox or rehab

Medical Detoxification at Three Rivers Behavioral Health

Three Rivers Behavioral Health offers medical detoxification as a core level of care within its behavioral health hospital in West Columbia, SC. For individuals dependent on substances, withdrawal can carry serious medical risks, and detox within a hospital setting provides a level of clinical oversight that freestanding detox clinics may not match. The facility operates 24 hours a day, meaning the intake process is not limited to business hours — a critical factor when withdrawal onset doesn't follow a schedule.

Following medical detox, the continuum at Three Rivers includes inpatient rehabilitation and acute psychiatric care for patients who need continued structured support. For those who stabilize and are ready for a lower level of care, the Partial Hospitalization Program and Intensive Outpatient Program offer structured programming without requiring an overnight stay. A Virtual Intensive Outpatient Program is also available, extending access for South Carolina residents who face geographic or logistical barriers to daily in-person attendance.

Levels of Care: From Inpatient Detox to Virtual Outpatient

The range of programs at Three Rivers Behavioral Health allows patients to move through a clinical continuum without changing providers. The facility's confirmed levels of care include Medical Detoxification, Adult Inpatient, Inpatient Rehabilitation, Acute Psychiatric, Partial Hospitalization Program, Intensive Outpatient Program, and Virtual Intensive Outpatient Program — all for adults. Adolescents between 11 and 17 have access to both inpatient and outpatient tracks designed for their age group.

That breadth is relevant for families coordinating care. A teenager in crisis, an adult managing chemical dependency, and a veteran navigating substance use and psychiatric symptoms can each find an appropriate level of care at the same West Columbia location. Three Rivers accepts TRICARE, the insurance plan covering military families, which reduces a common barrier for active-duty personnel and veterans seeking detox or inpatient rehab in South Carolina.

Who Three Rivers Serves

Three Rivers Behavioral Health treats adults and adolescents ages 11 through 17 across South Carolina. The conditions addressed include substance use disorders, chemical dependency, psychiatric disorders, and trauma — a scope that reflects the clinical reality that these issues frequently co-occur. For individuals whose detox or withdrawal management is complicated by underlying mental health conditions, being in a behavioral health hospital rather than a specialty-only detox facility can be a meaningful clinical advantage.

Military personnel, veterans, and first responders represent a specific population the facility is equipped to serve. Three Rivers accepts TRICARE and is open 24 hours, which aligns with the unpredictable schedules and acute-onset crises common in that population. Families or individuals in South Carolina who need to reach someone immediately can call (803) 796-9911 at any hour.
