Understanding Your Treatment Options

Choosing the right treatment facility is one of the most important decisions in the recovery journey. Research published by the National Institute on Drug Abuse (NIDA) shows that treatment duration, therapeutic approach, and aftercare planning are the three strongest predictors of long-term sobriety.

Chestnut Health Systems offers 3 distinct levels of care, allowing patients to step through treatment intensities as they progress. This continuum-of-care model — moving from higher to lower intensity — is recommended by SAMHSA as the gold standard for addiction treatment.

The facility utilizes 9 evidence-based therapeutic modalities. According to NIDA research, combination therapy approaches that integrate behavioral interventions (such as 1-on-1 Counseling and Cognitive Behavioral Therapy) with holistic support show significantly improved outcomes compared to single-modality programs.

Under the Mental Health Parity and Addiction Equity Act, most commercial insurance plans are required to cover substance abuse treatment. Chestnut Health Systems works with 24 insurance providers.
