Key Factors to Evaluate

1. Accreditation and Licensing

Look for facilities certified by:

  • OASAS (NYS Office of Addiction Services and Supports)
  • CARF International (Commission on Accreditation of Rehabilitation Facilities)
  • The Joint Commission

All OASAS-certified facilities meet New York State's rigorous standards for care.

2. Treatment Approaches

Evidence-based treatments should include:

  • Individual and group therapy
  • Family counseling
  • Medication-Assisted Treatment (MAT) when appropriate
  • Dual diagnosis treatment for co-occurring mental health conditions
  • Trauma-informed care

3. Location Considerations

Nassau County Options:

  • Closer to western Long Island communities
  • Easy access via LIRR and major highways
  • Multiple facilities in Hempstead, Garden City, and surrounding areas

Suffolk County Options:

  • Serving eastern Long Island
  • Facilities in Hauppauge, Smithtown, and Brookhaven
  • More residential settings available

4. Level of Care

Match your needs to the appropriate level:

  • Detox: Medical withdrawal management (3-7 days)
  • Inpatient/Residential: 24/7 structured environment (30-90 days)
  • Partial Hospitalization (PHP): Intensive day programs
  • Intensive Outpatient (IOP): Evening/weekend programs
  • Outpatient: Weekly individual and group sessions

5. Insurance Coverage

Most Long Island facilities accept:

  • New York State Medicaid
  • Medicare
  • Commercial insurance (Aetna, UnitedHealthcare, BCBS, etc.)
  • Self-pay with sliding scale options

Questions to Ask Facilities

  1. What is your staff-to-client ratio?
  2. Do you offer medication-assisted treatment?
  3. What is your approach to family involvement?
  4. Do you provide aftercare planning?
  5. What are your success rates and outcome measures?

Red Flags to Watch For

  • Promises of "guaranteed" recovery
  • High-pressure sales tactics
  • Lack of medical oversight
