About GateHouse
If you are looking at GateHouse in Nashua, NH, the basics worth knowing up front: The facility offers a continuum of care across multiple levels — PHP, IOP, Dual Dx — which means it can, in principle, hold a patient across the arc of a typical treatment episode. This page walks through the questions that tend to matter most to families weighing a specific program.
Care levels at GateHouse
The facility offers a continuum of care across multiple levels — PHP, IOP, Dual Dx — which means it can, in principle, hold a patient across the arc of a typical treatment episode. The practical question is whether it is genuinely strong at each level, or whether one level is the core business and the others are secondary. The useful move is to have an ASAM-aligned assessment done before admission — ideally by someone outside the facility's admissions team — to confirm that the level of care offered here is what the clinical picture calls for.
Insurance and payment
On insurance specifically: GateHouse accepts both Medicaid and commercial insurance, which is the broadest payer profile and typically correlates with programs that operate at scale across the economic spectrum. The facility also accepts TRICARE or military benefits. Before admission, ask the facility's utilization-review team for a written Verification of Benefits — not verbal assurance, which is where most post-treatment financial surprises come from. Also ask for specific plan-level confirmation, not carrier-level (e.g., "your Aetna PPO plan" not just "Aetna").
Specialty programming
The facility's documented specialty programming includes: Adult women, Adult men, Seniors or older adults. Specialty programming varies substantially by facility — some facilities offer "dual diagnosis" as a marketing category but not a clinical differentiator. Ask for the specific clinical-team credentials and the actual hours of specialty-specific content per week.
Before you call
The three questions that consistently separate programs worth considering from programs worth skipping: ASAM level of care match; written VOB for your plan; MAT policy. If the clinical situation involves opioid use disorder, confirm explicitly whether GateHouse offers medication-assisted treatment — buprenorphine, methadone, or naltrexone. Programs that do not are operating outside the current standard of care. Programs that cannot answer all three quickly are programs worth approaching with caution.
