What it means
What is dual diagnosis treatment?
Dual diagnosis treatment is care for a mental health condition and a substance use disorder together, in one plan.
Our clinical team treats both at once, rather than treating one first and leaving the other for later.
We offer it at every level of care we provide, from detox and inpatient care to outpatient and virtual programs.
Integrated treatment
One team treats both conditions in one plan, and your therapy looks at how each affects the other. This is how we treat dual diagnosis at Enhance.
Treating one at a time
One condition is treated first and the other is left for later, often with a different provider. Symptoms of the untreated condition raise the risk of relapse in the one that was treated.
SAMHSA recommends treating both conditions together, rather than one after the other.
Common pairings
Conditions we treat alongside substance use
Our dual diagnosis treatment programs treat mental illness alongside substance use disorders, including these common pairings.
What dual diagnosis treatment includes
Your plan combines these evidence-based therapies, and each one looks at how your mental health and substance use affect each other.
Individual therapy
One-to-one sessions with a licensed therapist, where you work on both conditions and how they feed each other.
Group therapy
Groups led by a licensed therapist, where you practice coping skills with other people in the program.
Family therapy
Sessions that include family members when involving them would help, so they understand both conditions.
Medication management
A licensed psychiatrist prescribes medication when it is part of your plan and reviews how it is working.
CBT, DBT and REBT
Cognitive behavioral therapy and other skills-based therapies help you notice the thoughts and urges behind substance use and respond differently.
EMDR and trauma-informed care
Therapy for trauma and post-traumatic stress disorder, for people whose trauma is part of both their mental health and their substance use.
When to consider it
Signs dual diagnosis care may be needed
Dual diagnosis care may be needed when mental health and substance use affect each other.
- Drinking or drug use gets worse when anxiety, low mood or memories flare up.
- You use alcohol or drugs to sleep, calm down or get through the day.
- Mental health treatment has not worked because the drinking or drug use returns.
- Addiction treatment has not worked because of depression, anxiety or trauma.
- You have a diagnosis such as bipolar disorder or PTSD as well as substance use.
- Family members notice that mood changes and substance use make each other worse.
Get help right away if
- Someone is thinking about ending their life.
- You think someone has overdosed.
- Someone cannot stay safe tonight.

Common questions about dual diagnosis
If your question is not answered here, call admissions at (714) 862-1907.
What is dual diagnosis called now?
Many clinicians now say co-occurring disorders, which means the same thing: a mental health condition and a substance use disorder at the same time.
How is dual diagnosis assessed?
Clinicians look at your mental health and your substance use together, and at how each affects the other, before a plan is set.
Can I join if I only have a mental health condition?
Yes. Our mental health programs treat people with or without substance use, and admissions will point you to the right one.
What is the difference between sequential, parallel and integrated treatment?
Sequential care treats one condition and then the other. Parallel care treats both at once with separate providers. Integrated care treats both with one team in one plan.
Why do mental health conditions and addiction so often occur together?
Some people use alcohol or drugs to cope with symptoms, and substance use can also make mood, anxiety and sleep worse over time.
How do clinicians tell substance-induced symptoms apart from a separate condition?
They look at when symptoms started and whether they continue once substances stop, which often becomes clearer as treatment goes on.
What happens if mental health symptoms return after substance use stops?
This can happen, and it is one reason we treat both together. Your team adjusts your therapy or medication as your symptoms change.
How is medication managed alongside addiction treatment?
When medication is part of your plan, a licensed psychiatrist prescribes it and reviews it with your therapists, so both conditions are considered.
Can treatment begin with detox and continue into outpatient care?
Yes. Detox is a first step, not a cure, so admissions plans the level of care you move into once it ends.
Can family members be involved in dual diagnosis treatment?
Yes. Family therapy can be part of your plan when involving family would help, and your team talks it through with you first.
How long does dual diagnosis treatment last?
It depends on your needs and the level of care your insurer approves. Your team reviews your progress and plans each step down with you.
Can dual diagnosis treatment happen online?
Virtual IOP and outpatient care can treat both conditions for people who are safe at home, and admissions can tell you whether that fits.
Does insurance cover dual diagnosis treatment?
Coverage depends on your plan: your deductible, your copay and what your insurer approves. Admissions checks your benefits with the insurer before you decide anything.
