Coverage
What TMS costs in California and how insurers approve it
Nearly every major California plan covers TMS for depression. The hold-up is almost never coverage — it is documentation.
California's largest insurers cover TMS for major depressive disorder, but all require documented failure of prior treatment. Blue Shield of California, Anthem Blue Cross, Kaiser Permanente, UnitedHealthcare, Aetna and Cigna typically require trials of two or more antidepressants — and often a course of psychotherapy — before approving TMS, with prior authorization handled through each plan's behavioral health team. Medi-Cal covers TMS through county managed care plans, with coverage criteria that vary by plan and county. Medicare covers TMS statewide under the Noridian local coverage determination. Always confirm benefits with the clinic before beginning treatment; coverage details and required documentation change plan to plan.
Plan by plan
Blue Shield of California
One of California's largest insurers. Covers TMS for treatment-resistant depression with prior authorization, usually requiring documented trials of two or more antidepressants.
Anthem Blue Cross of California
Covers TMS for treatment-resistant depression with prior authorization and medication-trial documentation.
Kaiser Permanente
Covers TMS for major depressive disorder that has not responded to medication and therapy; referrals go through your Kaiser care team.
UnitedHealthcare
Covers TMS under the behavioral health benefit; authorization is typically handled by Optum rather than the medical plan.
Aetna

Health Net
Covers TMS on many commercial and Medi-Cal managed care plans; authorization criteria vary by plan.
Medi-Cal (Medicaid managed care)
Coverage runs through county managed care plans — confirm with both the plan and the clinic, as criteria vary.
Medicare (Noridian Jurisdiction E)
Covers TMS for major depressive disorder under the Noridian local coverage determination, including many California Advantage plans with their own authorization step.
TRICARE West
Covers TMS for eligible service members and families with referral and authorization through TriWest.
Criteria change. Treat this as a starting point and confirm with your plan and clinic.

Getting approved faster
- Bring a list of every antidepressant you have tried, with doses and how long you took them.
- Ask your prescriber to note the reason each medication was stopped — side effects count.
- Have a recent PHQ-9 or similar score on file; most insurers want a current measure.
- Let the clinic submit the authorization — their staff do this daily and know the templates.
- If you are denied, appeal. Denials for incomplete documentation are routinely overturned.
