About Mount Sinai South Nassau Center for Primary and Behavioral Health

Mount Sinai South Nassau Center for Primary and Behavioral Health (Hempstead, NY) is a SAMHSA Behavioral Health Treatment Services Locator-registered facility. The facility offers a continuum of care across multiple levels — IOP, MAT, Dual Dx — which means it can, in principle, hold a patient across the arc of a typical treatment episode. Evaluation of this facility against current clinical standards should encompass ASAM 4e framework alignment, MAT policy, and payer-specific network status.

Care levels at Mount Sinai South Nassau Center for Primary and Behavioral Health

The facility offers a continuum of care across multiple levels — IOP, MAT, 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. ASAM Criteria 4e level-of-care matching requires clinical assessment across six dimensions (withdrawal potential, biomedical conditions, emotional/behavioral/cognitive conditions, readiness, relapse risk, recovery environment). The alignment of Mount Sinai South Nassau Center for Primary and Behavioral Health's offerings to any specific patient's clinical profile should be determined by an independent ASAM-aligned assessment prior to admission.

Insurance and payment

Payment and insurance posture: Mount Sinai South Nassau Center for Primary and Behavioral Health 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. Pre-admission Verification of Benefits (VOB) documentation should include: specific plan product and network status, deductible status at time of admission, coinsurance rate applicable, prior authorization status and turnaround, and out-of-pocket accumulation. Under MHPAEA 2024 disclosure rules, plan-specific medical-necessity criteria must be available on request.

Specialty programming

The facility's documented specialty programming includes: Young adults, Adult women, Adult men. Specialty-program verification requires review of: (a) dedicated specialty-track programming hours per week; (b) specialty-credentialed clinical staffing (e.g., LCSW with trauma specialization, perinatal-nurse certification, adolescent-development training); (c) specialty-specific clinical assessment protocols; (d) specialty-specific outcome measurement. Marketing designation alone is insufficient for clinical confidence.

Questions about this facility

Common questions about Mount Sinai South Nassau Center for Primary and Behavioral Health

Answered from public sources: SAMHSA listings, federal parity regulations, and our own admissions helpline intake notes.

Is Mount Sinai South Nassau Center for Primary and Behavioral Health listed in the SAMHSA Treatment Services Locator?

Mount Sinai South Nassau Center for Primary and Behavioral Health appears in our directory because it is sourced from the federal SAMHSA Behavioral Health Treatment Services Locator. The SAMHSA listing is the federal reference for licensed substance-use programs in the United States — inclusion requires active state licensure. If you want to verify independently, you can search by name or ZIP at findtreatment.gov.

What insurance does Mount Sinai South Nassau Center for Primary and Behavioral Health accept?

Insurance network lists change frequently, so the definitive answer is always to call the facility directly or call our helpline — we verify benefits on the line, for free. In general, most SAMHSA-listed programs in NY accept at least one commercial insurer plus Medicaid. Out-of-network coverage depends on your specific plan's behavioral-health benefits.

How do I know if this level of care is right for me?

The clinical answer comes from an ASAM assessment — a six-dimension evaluation of withdrawal risk, medical conditions, mental state, readiness to change, relapse potential, and living environment. A good intake conversation at Mount Sinai South Nassau Center for Primary and Behavioral Health (or any SAMHSA-listed program) will walk through those dimensions before recommending a level of care. If you would like help thinking through the fit first, take our 2-minute self-assessment.

Is calling confidential? Will my employer find out?

Substance-use treatment records are protected under 42 CFR Part 2 — a federal rule stricter than HIPAA. An employer cannot access your records without a court order or your written consent. Insurance claims will reflect that behavioral-health services were provided, but not the diagnosis or the content. Calls to our helpline and to Mount Sinai South Nassau Center for Primary and Behavioral Health directly are confidential.

What happens if I call the helpline instead of the facility?

Our helpline ((888) 333-RECOV) is answered 24/7 by licensed admissions counselors. They will ask about insurance, location preference, and clinical priorities, then match you against in-network verified programs. You can request Mount Sinai South Nassau Center for Primary and Behavioral Health specifically. There is no obligation to admit — the call is informational.
