Aetna’s TMS policy
Aetna covers TMS under Clinical Policy Bulletin (CPB) 0612. They consider it “medically necessary” for treatment-resistant depression — when you meet their criteria.
And Aetna’s criteria are stricter than most.
Requirements
Aetna needs all of the following:
- Diagnosis: Major Depressive Disorder (MDD), unipolar, non-psychotic
- Failed medications: At least 4 adequate antidepressant trials from at least 2 different classes
- Each trial: Adequate dose for at least 6 weeks
- Current episode: Moderate to severe depression (PHQ-9 score of 10+)
- Device: Must be FDA-cleared
That 4-medication requirement is the big one. Most insurers only ask for 2. If you have Aetna, make sure your psychiatrist documents every single trial thoroughly — including augmentation agents like lithium, Abilify, or thyroid. Aetna may count those.
Authorization process
- Your TMS clinic submits a precertification request
- They’ll include your psychiatric evaluation, full medication history with dates/doses/outcomes, and your PHQ-9 score
- Aetna typically responds in 5-10 business days
- Approval covers up to 36 sessions
Cost
- In-network: Copay or coinsurance after your deductible. Typical total: $500-$3,000
- Out-of-network: Much higher. Check your out-of-network benefits before going this route
Common issues
The 4-med requirement catches people off guard. Count everything. Every antidepressant you’ve tried, every augmentation strategy your doctor used. The more you document, the better your chances.
The Aetna-CVS Health merger hasn’t changed the TMS policy as of 2026.
One bright spot: Aetna Medicare Advantage follows standard Medicare TMS coverage, which typically requires only 2 failed medications. That’s half the hurdle of commercial Aetna.

How to Get TMS Approved
Call the number on the back of your insurance card and ask specifically about TMS therapy coverage. Get a reference number.
Gather records of your MDD diagnosis, all medication trials (names, doses, durations, outcomes), current PHQ-9 score, and therapy history.
Find an in-network TMS provider using our clinic directory. In-network clinics handle prior auth and know your insurer's requirements.
Your TMS clinic submits the prior auth request. Typical approval takes 5-15 business days. If denied, appeal — overturn rates are 60-70%.
What If You’re Denied?
Don't give up after a denial
TMS denial overturn rates are 60-70% on appeal. Steps to take:
- Request a peer-to-peer review — your psychiatrist talks directly to the insurer's medical director
- Submit additional documentation addressing the specific denial reason
- File a formal appeal with your state insurance department if internal appeals fail
- External review — most states allow independent external review of coverage denials

TMS for conditions beyond depression
Aetna’s CPB 0612 covers TMS primarily for treatment-resistant MDD. However, coverage is evaluated for:
- OCD: Aetna may cover BrainsWay Deep TMS (FDA-cleared for OCD) with strong documentation
- Anxiety with depression: Case-by-case basis
- Bipolar depression: Generally not covered — TMS for bipolar carries additional risk considerations
Deep TMS (BrainsWay H-coil)
Aetna covers deep TMS (BrainsWay) for OCD under FDA clearance. Your TMS clinic will need to submit documentation specifically referencing BrainsWay’s OCD indication.
Aetna vs other insurers
Aetna’s 4-medication requirement is stricter than most. If you’ve been through comprehensive medication trials under Aetna’s pharmacy management, you’re in a better position for approval. If you switched from another insurer, make sure your psychiatrist includes records from prior treatments — those count toward the 4-trial requirement even if they were with a different plan.
