What Evernorth covers at Mugen

Under Evernorth, care with us typically includes a thorough psychiatric evaluation, ongoing medication management, and follow-up visits, in person at our Oak Brook office in DuPage County or by secure video anywhere in Illinois, including Chicago and Cook County. Our team verifies your benefits by phone before your first visit.

Psychiatric evaluation

A thorough first visit to understand your history, what you're experiencing now, and your goals, then a plan built together.

Medication management

Individualized medication management reviewed and adjusted with you over time to align with your goals.

Telehealth across Illinois

What Evernorth members should know

If you have been told your behavioral health benefits are administered by Evernorth and you have never purchased an Evernorth plan, nothing is amiss. Evernorth is Cigna’s health services division; it operates the behavioral health network behind Cigna coverage. Most people who have Evernorth benefits carry a Cigna card.

Mugen participates in the Evernorth Behavioral Health network, which is what makes psychiatric care here covered for Cigna members: evaluation, medication management, and follow-up visits, in person in Oak Brook or by video across Illinois. Send us the details from your card, under whichever name appears on it; our office verifies your coverage before your first visit, and your own benefit specifics are available through your myCigna account at mycigna.com or the behavioral health number on your card.

/ˈfaqs/

Evernorth

questions, answered.

We know starting psychiatric care often comes with questions. Below are answers to some of the things people ask us most before scheduling a consultation.

Do you accept Evernorth?

Yes. Mugen Psychiatry is in-network with Evernorth for adult psychiatric care in Illinois. Reach out and we will confirm your benefits for free before your first visit.

Can I see an Evernorth psychiatric provider by telehealth?

Yes. Most care, including evaluations and medication management, can be delivered by secure video anywhere in Illinois, with in-person visits available at our Oak Brook office.

Will my care be consistent at every visit?

Yes. We follow standardized psychiatric clinical practice, so you receive the same standard of care at every visit.

Where is your office located?

Our office is at 600 W 22nd St, Suite 260, Oak Brook, IL 60523, in DuPage County. We serve Chicago and Cook County in person and all of Illinois by secure telehealth.

Is Evernorth the same as Cigna?

They are one family: Cigna is the insurer, and Evernorth is its health services division, operating the behavioral health network. If either name appears on your paperwork, the same benefits check applies here.

Why does my card say one name and my approval another?

The medical and behavioral sides of a Cigna plan are administered under different names. It is a common source of confusion, and it has no effect on booking care at Mugen once your benefits are verified.
/ˈimportant/

If you're in crisis, call or text 988 (Suicide & Crisis Lifeline) or call 911. Mugen Psychiatry provides outpatient care and is not a 24/7 crisis service.
