Navigating health insurance for a specialized treatment like Transcranial Magnetic Stimulation can raise questions about eligibility, coverage, and what you may owe. Shasta Administrative Services works with self-funded employer health plans and specialized benefit programs, so the benefits available to you depend on the specific plan your employer provides.
At Shanti TMS, located at 3769 SE Milwaukie Ave in Portland, Oregon, we provide physician-led outpatient TMS and help patients navigate the insurance process. Our team works to clarify how your Shasta-administered benefits apply to treatment, including coverage verification, prior authorization requirements, and potential cost-sharing, so you can make informed decisions about your care.

Understanding Your Shasta Health Benefits
Shasta Administrative Services acts as a third-party administrator (TPA) for health plans, including self-funded employer plans. Rather than offering one standard insurance policy to every member, Shasta helps administer benefits established by individual employers. As a result, coverage for behavioral health services can differ from one plan to another.
Your plan documents outline the services your benefits include and the requirements you must meet to access them. Reviewing those details helps establish whether your plan includes TMS and what conditions you must meet before treatment begins.
Does Shasta Administrative Services Cover TMS?
Shasta-administered health plans may cover TMS when the treatment meets the plan’s behavioral health benefits and medical-necessity criteria. Coverage depends on your specific plan, the condition being treated, and any applicable authorization requirements. A plan that covers TMS for one diagnosis may apply different criteria to another.
TMS uses magnetic pulses to stimulate targeted areas of the brain involved in mood and other symptoms. Clinicians commonly use it to treat depression, including depression that has not improved enough with medication. TMS also has specific applications for conditions such as obsessive-compulsive disorder (OCD). Your diagnosis and treatment history help determine which clinical criteria apply to your care.
How Medical Necessity Affects TMS Coverage
Insurance plans often require evidence that TMS meets their medical-necessity criteria before they authorize treatment. These criteria help the plan determine whether the treatment is appropriate for your diagnosis and clinical history.
Depending on your plan and diagnosis, the review may consider:
- Your diagnosis and current symptoms.
- The severity and duration of your symptoms.
- Previous treatments, including medications you have tried.
- Medication dosages, treatment duration, and response.
- Clinical records supporting the recommendation for TMS.
Your provider can assess your symptoms and treatment history to determine whether TMS may be appropriate. Shanti TMS can also help identify the clinical information your plan requires for its coverage review.
Conditions Shanti TMS Treats
TMS targets specific brain circuits involved in mental health symptoms. Clinicians use different protocols depending on the condition, and insurance criteria may differ by diagnosis. Understanding how TMS treats your condition can help clarify the clinical information your plan may need to review.
Major Depressive Disorder
Major depressive disorder (MDD) can cause persistent sadness, loss of interest, low energy, difficulty concentrating, and changes in sleep or appetite that interfere with daily life. TMS delivers magnetic pulses to targeted brain regions involved in mood regulation, helping modulate activity in these circuits. Clinicians use TMS as an established treatment for depression, particularly when antidepressant medication has not provided enough relief. During the insurance review, your plan may require documentation of your diagnosis, symptoms, and previous treatment.
Treatment-Resistant Depression
Treatment-resistant depression describes depression that has not responded adequately to appropriate treatment attempts, often including antidepressant medications. TMS offers a different approach by directly stimulating targeted brain regions involved in mood regulation rather than relying on medication alone. Because treatment history often plays a central role in coverage criteria for treatment-resistant depression, your plan may request details about medications you have tried, how long you took them, and how well they worked.
Obsessive-Compulsive Disorder
Obsessive-compulsive disorder (OCD) involves recurring, unwanted thoughts or urges and repetitive behaviors or mental rituals that can be difficult to control. TMS for OCD uses a specific treatment protocol to target brain circuits associated with obsessive thoughts and compulsive behaviors. Because the protocol and clinical criteria differ from those used for depression, insurance requirements may also differ.
Other Conditions
Shanti TMS also offers treatment for conditions such as postpartum depression, panic disorder, post-traumatic stress disorder (PTSD), chronic pain, and addiction. The evidence supporting TMS, established treatment protocols, and regulatory indications vary across these conditions. Insurance coverage also depends on the diagnosis and the specific plan. Your provider can evaluate whether TMS fits your clinical needs, and our team can verify the applicable benefits and coverage requirements.

Prior Authorization and Other Coverage Requirements
Some health plans require prior authorization before they cover TMS. Prior authorization means the insurer or plan administrator reviews clinical information before treatment begins to determine whether the requested service meets its coverage criteria. The process may involve submitting a diagnosis, treatment history, and supporting records.
Your Shasta-administered plan determines whether prior authorization applies and what documentation it requires. Shanti TMS can check those requirements, explain the information your plan needs, and help coordinate the insurance verification process before you begin treatment.
How Shanti TMS Helps With Insurance Verification
Understanding your benefits involves more than confirming whether your plan includes TMS. You also need to know which clinical criteria apply, whether the plan requires prior authorization, and what costs you may owe.
Shanti TMS helps you clarify those details by:
- Verifying your benefits: We check whether your Shasta-administered plan includes TMS coverage for your diagnosis.
- Identifying coverage requirements: We help clarify the medical-necessity criteria and clinical documentation your plan may request.
- Checking prior authorization: We determine whether your plan requires authorization before treatment.
- Reviewing potential costs: We help you understand applicable deductibles, copays, coinsurance, and other out-of-pocket expenses.
Start with our insurance verification process so our team can review your benefits and explain the next steps.
Understanding Your Potential TMS Costs
Even when a health plan covers TMS, your out-of-pocket costs depend on the details of your benefits. These common insurance terms can help you understand what you may owe:
- Deductible: The amount you pay for covered services before your plan begins paying according to its benefits.
- Copay: A fixed amount you pay for a covered service, such as a treatment visit.
- Coinsurance: The percentage of a covered service’s cost you pay after meeting your deductible, when applicable.
- Out-of-pocket maximum: The most you pay for covered, in-network services during your plan year for benefits subject to that limit. After you reach it, your plan pays 100% of eligible covered costs for the remainder of the plan year.
Your specific plan determines how these costs apply to TMS. Shanti TMS can help you review your benefits and understand your potential financial responsibility before treatment begins. For an accurate estimate, confirm the details of your plan and any applicable cost-sharing with our team.
