What TriWest covers at Mugen

Under TriWest, care with us typically includes a thorough psychiatric evaluation, ongoing medication management, and follow-up visits for veterans and military families, 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

Most care can be delivered by secure video anywhere in Illinois, with in-person visits at our Oak Brook office.

We treat ADHD, anxiety, depression, bipolar disorder, PTSD, and OCD for Veterans with VA authorization. Care is provided by our board-certified psychiatrists and psychiatric nurse practitioners, both in network under this plan.

/ˈtriwest, specifically/

What Veterans using TriWest should know

TriWest coverage operates in a different sequence from every other plan on this list, and understanding that sequence protects you financially. TriWest administers VA Community Care, the program through which Veterans receive care from community providers such as Mugen when the VA refers them. The referral comes first: the VA authorizes care with a specific provider before that care begins. With an authorization in place, care is typically provided at no cost to you, and the VA manages the billing directly. Without one, a Veteran can be left responsible for the cost and required to pursue reimbursement afterward.

The path, in order: speak with your VA facility’s community care office or your VA provider about a psychiatry referral; request Mugen Psychiatry in Oak Brook by name if you would like to be seen here; and once your referral is in place, we can book your first appointment. If you already hold an authorization and are unsure whether it covers care at Mugen, contact us and we can confirm it for you.

Once your referral is in place, accepting new patients describes what your first visit involves.

Because this plan is referral-first, do you need a referral to see a psychiatrist in Illinois explains how referral rules differ across plans.

/ˈfaqs/

TriWest

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 TriWest?

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

Can I see a TriWest 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.

Can I call Mugen directly and book with TriWest coverage?

You are welcome to call, and if a VA referral is not yet in place, our first step will be directing you to your VA community care office, because the program requires authorization before care begins. That order protects you from unexpected cost.

I already have an authorization. What now?

Contact us with the details. We can confirm whether it covers care at Mugen. We are accepting new adult patients.
/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.
