Frequently asked questions

How do I confirm a Ontario provider is still in the Sedgwick network?

Call the practice and ask the front desk to verify active Sedgwick participation for workers' compensation. Cross-check with your claims adjuster before the appointment. Sedgwick updates its CA roster periodically; a provider listed today may exit the network before your visit.

What if no Sedgwick provider in Ontario has my specialty?

Sedgwick is required to provide reasonable access to specialty care. If no in-Sedgwick specialist is available within reasonable distance of Ontario, your claims adjuster must authorize an out-of-network referral. Get the authorization in writing before the visit.

Can I switch Sedgwick providers in Ontario after my first visit?

Yes. Sedgwick typically allows you to switch to any other in-network provider once without prior approval, in most California cases. Subsequent switches may require justification. Notify your claims adjuster in writing whenever you change providers.

Is there a cost to see a Sedgwick Ontario provider?

No — the insurance carrier (or self-insured employer) pays the provider directly under the California workers' compensation fee schedule. If a Sedgwick provider tries to bill you for a covered WC visit, contact the claims adjuster immediately before paying.
