Outpatient mental health and substance abuse centers provide scheduled and walk-in clinical services to patients who do not require inpatient hospitalization — including individual and group therapy, psychiatric evaluation, medication management, and structured outpatient or intensive outpatient programs (IOP). Some facilities also offer medication-assisted treatment (MAT) for opioid or alcohol use disorder. Patients typically attend sessions during the day and return home, though some programs involve daily attendance for several hours.
Questions to investigate
- What specific services are offered — individual therapy, group therapy, medication management, MAT, detox observation, or partial hospitalization?
- Are any services delivered via telehealth, and if so, in which states are patients located?
- What licensed clinician types are on staff — LCSWs, LPCs, psychologists, psychiatrists, nurse practitioners?
- Does the facility dispense or administer medications on-site, including buprenorphine, methadone, or naltrexone?
