What Optum covers at Mugen

Under Optum, 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

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 under Optum-administered plans. Care is provided by our board-certified psychiatrists and psychiatric nurse practitioners, both in network under this plan.

What Optum members should know

Optum does not issue its own member cards, yet millions of people hold Optum behavioral health benefits. Optum is UnitedHealth Group’s health services company, and it administers mental health coverage for United Healthcare plans and for many employer programs. If a provider directory, an employer assistance letter, or liveandworkwell.com directed you here, this page is the right one.

Mugen participates in the Optum Behavioral Health network, which covers psychiatric care here for the plans Optum administers: evaluation, medication management, and ongoing visits, in person in Oak Brook or by video across Illinois. If you are uncertain whether your plan routes through Optum, send us what appears on your card and our office traces where your behavioral health benefits are held, or sign in at liveandworkwell.com with the group number from your card to view your behavioral health benefits directly.

/ˈfaqs/

Optum

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 Optum?

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

Can I see an Optum 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.

My card says United Healthcare but I was told I have Optum. Which is correct?

Both. United Healthcare is the insurer; Optum administers the behavioral health side. The benefits check here treats them as the single plan they are.

An employer assistance letter mentioned Optum. Does that cover psychiatry at Mugen?

Employer assistance programs vary in scope and session limits. Send us the details and we will verify what your program includes before anything is scheduled.
/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.
