What to expect from rehab in Columbia
- Medical detox (3–7 days) — 24/7 medically supervised withdrawal for alcohol, opioids, benzodiazepines. Vital in Columbia for severe physical dependence.
- Inpatient/residential (28–90 days) — immersive live-in programs, usually the highest success rates for severe addiction.
- Partial hospitalization (PHP) — structured daytime treatment (20+ hours/week) with evenings at home or sober living.
- Intensive outpatient (IOP) — 3–5 sessions per week (9–12 hours) while maintaining work or family obligations.
- Medication-assisted treatment (MAT) — FDA-approved medications (buprenorphine, methadone, naltrexone) combined with counseling. Evidence-based gold standard for opioid use disorder.
Paying for treatment in Columbia
Under the Mental Health Parity and Addiction Equity Act, most private insurance plans must cover addiction treatment at the same level as medical care. Maryland has expanded Medicaid under the ACA, so low-income adults can access treatment through the state Medicaid program. For uninsured residents of Columbia, options include SAMHSA block-grant-funded centers, sliding-scale fees, payment plans, and state-funded programs. Call SAMHSA's National Helpline at 1-800-662-HELP (free, 24/7) for local referrals.
