Healthfirst Medicaid for Long Island Addiction Treatment

Does Healthfirst Medicaid cover out-of-state inpatient rehab?

Sometimes. Healthfirst Medicaid generally requires that inpatient SUD treatment be provided in-network — usually within New York State. Out-of-state inpatient rehab may still be covered under the right circumstances.

• No in-network bed available for the medically necessary level of care
• The out-of-state facility is enrolled with NY Medicaid
• Prior authorization is approved on a single-case agreement
• The stay is for crisis stabilization or medically necessary care unavailable in-state

Does Healthfirst Medicaid require prior authorization for inpatient rehab?

Yes for most inpatient stays. Healthfirst Medicaid typically requires prior authorization (PA) for inpatient SUD treatment, including 28-day rehab and detox. Outpatient services like IOP and MAT usually do not require PA under NYS Medicaid rules.

• Inpatient rehab — PA required (clinical packet sent by admitting facility)
• Detox — PA required, often expedited (same-day decision)
• IOP — no PA required for in-network outpatient
• MAT (Suboxone, Sublocade, Vivitrol) — PA waived for most agents under NYS rules

Does Healthfirst Medicaid cover 28-day inpatient rehab?

Yes. Healthfirst Medicaid covers 28-day inpatient drug and alcohol rehab at Healthfirst-Medicaid-approved facilities, subject to medical-necessity criteria. New York State Medicaid plans must by law authorize at least 4 weeks of inpatient SUD treatment when medically necessary.

• First 4 weeks must be authorized when medically necessary (NY State law)
• Continued stay reviews based on the LOCADTR or ASAM criteria
• We coordinate referrals to in-network 28-day programs
• We send the clinical packet to admissions on your behalf

Does Healthfirst Medicaid cover residential treatment?

Yes, when medically necessary. Healthfirst Medicaid covers residential substance use treatment at in-network facilities with prior authorization. Residential is typically reserved for guests who need 24/7 supervision but do not require medical detox.
