Frequently Asked Questions

What Medicaid plans do you accept?
We accept Medicaid managed care plans including Fidelis Care, Healthfirst, Molina Healthcare, Anthem HealthPlus, and UHC Community Plan. We do not accept MetroPlus due to limited Long Island network, but we offer free help to switch plans.
Are there copays for Medicaid addiction treatment?
Many services, like outpatient counseling and medication-assisted treatment (MAT), have no copays under NY Medicaid guidelines. Essential Plan members may have low copays ($0-$15) based on income.
Does Medicaid require prior authorization for rehab?
No prior authorization is required for key SUD treatments, including certain medications, to ensure timely access to care. This applies to both Medicaid and Essential Plan members.
What is the difference between Medicaid and Essential Plan?
Medicaid provides full coverage for eligible low-income individuals with typically $0 copays. The Essential Plan is a state-subsidized option for those who don't qualify for Medicaid, with $0 premiums, low copays (often $0-$15 based on income), and no deductibles, covering similar SUD services.
Can I switch my Medicaid managed care plan?
Yes. New York Medicaid allows you to switch managed care plans at any time for certain reasons, including lack of access to in-network providers in your area. We can help you switch to a plan we accept—at no cost to you.
Does Medicaid cover medication-assisted treatment (MAT)?
Yes, fully. Medicaid covers FDA-approved medications for addiction treatment including Suboxone, Vivitrol, Sublocade, and other MAT options when prescribed as part of a comprehensive treatment program.
What are the in-network benefits for Long Island residents?
As an in-network provider, Integrity Treatment Partners offers seamless access to intensive outpatient programs (IOP) and group therapy with minimal out-of-pocket costs. Most Medicaid members pay $0 for covered services.
