Dual Diagnosis Treatment: What to Expect, Who It's For & How It Works

Maybe you drink to cope with anxiety, or depression gets worse when you're not using. Treating just one usually doesn't work long-term. Dual diagnosis programs have both addiction specialists and mental health professionals working together on your care.

Dual Diagnosis Treatment(Dual Diagnosis)

Residential Setting

If you're dealing with both a mental health condition and a substance use disorder, dual diagnosis treatment addresses both at the same time—because they're usually connected. Maybe you drink to cope with anxiety, or depression gets worse when you're not using. Treating just one usually doesn't work long-term. Dual diagnosis programs have both addiction specialists and mental health professionals working together on your care.

Typical Duration

30-90 days (residential) or 8-12 weeks (outpatient)

Hours Per Week

Varies by setting

This level may be appropriate for:
  • People struggling with both addiction and a mental health condition
  • Those whose substance use and mental health symptoms are intertwined
  • Individuals who've tried treatment that only addressed one issue
  • People who need coordinated psychiatric and addiction care

Who decides what level of care is right?

When you call a treatment facility, they'll do an assessment to understand your situation— things like what substances you're using, how long, medical history, mental health, and your support system. Based on that, they'll recommend a level of care. Your insurance company also has a say—they use clinical criteria (like ASAM for substance use) to decide what they'll cover. Sometimes there's back-and-forth between the facility and insurance to find the right fit.

Does Insurance Cover Dual Diagnosis?

Most insurance plans cover dual diagnosis treatment when it's deemed medically necessary—but what "medically necessary" means varies by insurer. Your coverage depends on your specific plan: your deductible, copays, and whether the facility is in-network. The facility's admissions team can usually help you verify benefits before you commit.

What to Ask When Contacting a Program

Be prepared with the right questions

That first phone call to a treatment facility can feel intimidating. Here's the thing: the people answering are usually experienced at helping nervous callers navigate this process. You don't need to have all the answers—just your insurance card and a basic idea of what's going on. But it helps to know what questions to ask them:

  • 1Are you currently in-network with my specific insurance plan? (Give them your insurance ID and group number)
  • 2Can you verify my benefits and tell me roughly what my out-of-pocket costs would be?
  • 3Do you handle the prior authorization process, or do I need to call my insurance first?
  • 4Do you have availability right now? How long is the wait for admission?
  • 5What does a typical day look like in your program?
  • 6What credentials do your therapists and counselors have?
  • 7Do you offer medication-assisted treatment (like Suboxone or Vivitrol) if that's appropriate for me?
  • 8What happens after I complete your program? Do you help with aftercare planning?
  • 9Can my family be involved in my treatment?
  • 10What happens if my insurance stops approving coverage before I'm clinically ready to leave?
  • 11Do you treat people with both addiction and mental health issues at the same time?
  • 12How do you customize treatment plans for each person?

Before You Call

  • Have your insurance card ready
  • Know your policy number and group number
  • Be ready to briefly describe the situation
  • Have pen and paper for notes

What Intake May Ask You

  • What substances or symptoms are involved
  • History of prior treatment attempts
  • Current medications
  • Timeline for when help is needed

Here's something important to remember: calling a facility doesn't commit you to anything. You can (and should) call multiple places to compare options. The intake team is there to help you figure out if their program is right for your situation. If it's not the right fit, a good facility will tell you honestly and may even suggest alternatives.
