What to verify before calling Hamilton Treatment Services

• NJ DMHAS licensure — confirm current status via the NJ DMHAS licensure lookup.
• Insurance network status — call your insurance carrier and verify that Hamilton Treatment Services is currently in-network for your specific plan. Self-reported payer acceptance in the SAMHSA directory is a starting point, not proof of current in-network contract.
• Current level of care availability — ask specifically about bed or slot availability at the level of care you need. SAMHSA-listed services do not guarantee current open admissions.
• Medications policy — if you’re on prescribed buprenorphine, methadone, or other psychiatric medication, confirm the facility’s policy on maintaining your medication during treatment.
• Length-of-stay expectations — ask what a typical length of stay looks like for patients with your clinical presentation.
• MAT specifics — which specific medication(s), induction/transition protocol, and continuation plan post-discharge.
• CARF accreditation — verify current status at carf.org.
