Is TMS Therapy Covered by Insurance in Maine?

Most major insurers cover TMS — but you need to meet specific criteria and navigate prior authorization. Here's exactly what to expect.

When patients first hear about TMS therapy, one of their first questions is almost always the same: will my insurance cover this? The good news is that yes — most major insurance plans in Maine do cover TMS therapy, and coverage has expanded significantly over the past several years. But coverage is not automatic. You need to meet specific FDA-approved criteria, and the prior authorization process requires documentation.

In this article, I'll walk through exactly which insurers cover TMS, what criteria you need to meet, and how our team handles the prior authorization process on your behalf.

Which Insurers Cover TMS in Maine?

TMS therapy has been FDA-cleared since 2008 for major depressive disorder. Since then, coverage has expanded broadly. The following plans generally cover TMS when criteria are met:

  • Aetna — covers TMS for MDD after two failed antidepressant trials
  • Anthem Blue Cross Blue Shield — covers TMS with documented treatment resistance
  • Cigna — covers TMS for MDD with prior authorization
  • UnitedHealthcare — covers TMS for MDD and, in some plans, OCD
  • Harvard Pilgrim Health Care — covers TMS for treatment-resistant MDD
  • Medicare — covers TMS for MDD under Medicare Part B
  • MaineCare (Medicaid) — coverage available for qualifying patients

Employer-sponsored plans and individual marketplace plans in Maine generally follow their parent insurer's medical policy. If you're unsure about your specific plan, our billing team will verify your benefits before your first appointment at no charge.

What Criteria Must Be Met?

Insurance coverage for TMS is not simply about having depression. You need to meet medical criteria that are consistent with the FDA's approved indication. The standard requirements across most insurers include:

  1. Diagnosis of major depressive disorder (MDD) — specifically, a current depressive episode
  2. Failure of at least two adequate antidepressant trials — "adequate" means an appropriate dose for at least 4–6 weeks during the current episode
  3. Currently under the care of a psychiatrist or prescribing provider — TMS must be part of a broader psychiatric treatment plan
  4. No contraindications — primarily the absence of magnetic metal implants in or near the head

Some insurers require that one of the failed antidepressant trials be from a different class (e.g., an SSRI and an SNRI), and some require a period of adequate psychotherapy. We'll review your specific history during your consultation to determine which criteria you meet and identify any gaps that need documentation.

How Prior Authorization Works

Before a single TMS session can be billed to insurance, your insurer requires prior authorization — written approval confirming that TMS is medically necessary for you. This is the step that delays or derails treatment for many patients at other practices. Our team handles it differently.

Here is what the prior authorization process looks like when you come to Portland Mental Health & Psychiatry:

  1. We verify your benefits — before your first appointment, our billing team confirms that TMS is a covered benefit under your specific plan.
  2. We gather documentation — during your TMS consultation, Dr. Crocker reviews your medication history and prior treatment records to build the prior auth case.
  3. We submit on your behalf — our team handles all paperwork, clinical notes, and communication with your insurer.
  4. We appeal denials when warranted — if an insurer denies the initial request, we have a strong track record of successful peer-to-peer appeals.

In our experience, the majority of patients who meet FDA criteria are ultimately approved. The process typically takes 5–15 business days from submission to decision.

What Does TMS Cost Without Insurance?

A full TMS treatment course — typically 36 sessions over 6–9 weeks — costs between $6,000 and $12,000 without insurance. The wide range reflects differences in equipment, provider fees, and geographic market.

For patients who do not have insurance coverage or who are denied after appeals, we offer self-pay rates and can discuss financing options. In many cases, even patients who initially believe they won't qualify for coverage are approved after our team submits a well-documented prior authorization.
