Questions people ask about McLean Fernside
Is McLean Fernside residential or day treatment?
They provide inpatient residential. Whichever one you start at the usual pattern is to step down through the levels rather than stop at once, and Westminster is the closest place to carry that on if you move.
Is detox part of what McLean Fernside offers?
No detox here. A center can still take someone after a detox elsewhere, which is the common order of events, and the nearest one is 5.2 miles away in Westminster.
Who is McLean Fernside for?
They treat adults from 26 to 64 and young adults from 18 to 25, alongside programs for adult men and adult women, which is more than most places around Princeton name.
Can McLean Fernside treat anxiety alongside addiction?
They treat both. A diagnosis left untreated while the substance use is treated is the usual reason a first attempt does not hold, and Westminster is the nearest place to try instead if this one does not fit.
Is there an interpreter at McLean Fernside?
They work in 1 language beyond English: Sign language. Ask whether the group sessions in Princeton are in it too, or only the one to one ones.
How do I choose between two centers?
Compare the specifics, because almost every center describes itself in the same words. Paying a marketing company for referrals is common in this field, so who answers the phone is not always who treats you. Ask every place the same four questions and compare the answers side by side.
What if I have no insurance?
Addiction treatment sits alongside other medical benefits on most plans, so some coverage is the normal case. Approval can arrive in stages, with the detox cleared while the level of care after it is still under review. Call (844) 822-5800 and someone can look at the plan with you before you commit to anything.
Is what I say in a session confidential?
Privacy rules on this are tighter than most people expect, and they apply from the first phone call. There are narrow exceptions, including a medical emergency and a court order, and they are narrower than people assume. Ask who the center is allowed to speak to, and make sure the answer matches what you want.
