Questions worth asking before admission

• Which levels of care are available right now, and is there a waiting list?
• Which withdrawal medications are used, and who supervises them?
• How long is a typical stay, and how is the step-down plan made?
• Can family be involved, and how is aftercare arranged on Long Island?

Insurance and paying for care

Seafield Center is a New York State licensed provider, and many commercial plans, Medicaid managed care plans, and union or employee assistance programs include substance-use treatment benefits. Coverage varies by plan, by level of care, and by whether the facility is in your plan's network, so no coverage outcome can be assumed from this page.

• Ask the facility's intake staff to run a benefit check and tell you, in writing, what your plan is expected to pay.
• Ask whether the program is in network with your specific plan, not only with the insurance company.
• Ask what a prior authorization requires and how many days are typically approved at a time.
• Ask for the estimated out-of-pocket cost, including deductible, coinsurance, and any deposit.
• If you have Medicaid or a Medicaid managed care plan, ask which plans the program currently accepts.

We do not verify insurance and cannot guarantee coverage or payment. Confirm all benefit details directly with the facility and with your insurer before admission.
