Start with the verified MVBH role
Use MVBH admissions for the verified treatment-start route, then contact MVBH when the question concerns MVBH directly.
The clearest owned action in the supplied evidence is the admissions conversation. To start treatment at Merrimack Valley Behavioral Health in Amesbury, Massachusetts, call 978-233-9597 for a confidential conversation. This supports MVBH ownership of that starting contact.
It does not establish ownership of every later records decision. It also does not identify a particular record holder, requester, recipient, or disclosure purpose. Those distinctions matter when a question moves from starting treatment to handling discharge records.
For the Start with the verified MVBH role decision, separate confirmed evidence from open questions and individual circumstances. Record which detail would change the next step. Ask MVBH to confirm current access, eligibility, coverage, scheduling, credentials, and available services. Compare each answer with the cited evidence and this page's stated limits. That process supports a practical decision without turning general guidance into an MVBH promise.
