Dual diagnosis means a substance use disorder and a mental health condition are present together. This page approaches that from the addiction side: you came in for alcohol, opioids, or stimulants, and a mental health condition turned out to be driving part of it.

If you are arriving from the other direction — a mental health condition first, with substance use alongside it — the same care is described from that angle on our co-occurring disorders treatment page. Both pages describe the same coordinated care; they differ only in where you started.

Treating one and referring the other out tends to fail. We treat both in the same building, with the same clinical team.

How the two tracks fit together

Golden Coast Rehab holds DHCS substance use disorder certification 370254AP for outpatient detoxification, outpatient, intensive outpatient, and medication-assisted treatment.

Golden Coast Rehab is a contracted provider of Specialty Mental Health Services (Partial Hospitalization Program and Intensive Outpatient Program) for the County of San Diego, Behavioral Health Services, under County Contract 575462.

One boundary matters here, and we state it plainly. Our Partial Hospitalization Program is a specialty mental health service only, delivered under our County of San Diego contract — there is no substance use PHP at Golden Coast Rehab. Substance use care is provided at the outpatient detox, outpatient, intensive outpatient, and medication-assisted treatment levels under our DHCS certification. The two tracks are coordinated by one clinical team, but they are separately authorized and we do not blur them.

Why the mental health side cannot wait

A long-standing convention in addiction treatment held that a person had to get clean before anything else could be addressed. In practice that ordering fails often, because the untreated depression, trauma, or anxiety is frequently what the substance was managing. Take away the substance, leave the condition, and the pressure to return is enormous.

Integrated care means both are treated at once, by one team, with a single plan — and nobody is told to come back when they have some clean time before their psychiatric symptoms are addressed.

What treatment looks like

Assessment

A single evaluation covering substance use history, withdrawal risk, psychiatric symptoms, medical history, and safety. Symptoms are tracked with standardized measures, including the PHQ-9 and the GAD-7 where clinically indicated, completed at intake and repeated during treatment so that change is measured rather than assumed.

Stabilization

Outpatient withdrawal management where it is needed, under DHCS certification 370254AP, with psychiatric symptoms monitored throughout rather than after.

Active treatment

Substance use programming at the outpatient, intensive outpatient, or medication-assisted treatment level, coordinated with specialty mental health care at the PHP or IOP level under our County of San Diego contract. Medications for opioid or alcohol use disorder and psychiatric medications are managed together.

Step-down and aftercare

A relapse plan covering both conditions, since each is a reliable trigger for the other, plus continuing outpatient care and community supports.

Questions, Answered

FAQs About Dual Diagnosis Treatment

What does dual diagnosis mean?

That a substance use disorder and a mental health condition are present at the same time. It is common rather than unusual, and it needs both conditions treated together.

Do I need clean time before you will address my depression or anxiety?

No. Both are treated concurrently by one clinical team. Waiting to treat the psychiatric condition is a common reason people relapse.

Do you have a substance use PHP?

No. Partial hospitalization at Golden Coast Rehab is a specialty mental health service under County Contract 575462. Substance use care runs at the detox, outpatient, intensive outpatient, and medication-assisted treatment levels under DHCS certification 370254AP.

Can I take medication for opioid or alcohol use disorder while on psychiatric medication?

In most cases yes, and managing them together is the point of integrated care. Our psychiatric provider reviews the full regimen rather than treating each in isolation. See <a href="/treatment-programs/medication-assisted-treatment/">medication-assisted treatment</a>.

Do you provide residential treatment?

No. Golden Coast Rehab is outpatient only in both lanes. If your assessment shows you need residential or inpatient care, we will tell you and help you find it.

Does Medi-Cal cover dual diagnosis treatment?

Yes, at no cost to you, on any Medi-Cal plan in San Diego County — both lanes are administered through San Diego County Behavioral Health Services.

How common is it to need treatment for both a mental health condition and a substance use disorder in San Diego County?

Among clients in San Diego County's public behavioral health system, 60% had a co-occurring mental illness and substance use disorder in fiscal year 2020-21, up from 54% five years before, showing the overlap has grown here. SAMHSA's 2022 national survey put the share of 18-to-25-year-olds with a mental illness or substance use disorder at 48.8% had either condition in the past year. Dual-diagnosis programming treats both at once instead of requiring one to be resolved before addressing the other.

How do you screen for a co-occurring mental health condition?

We use the PHQ-9 to screen for depression severity and the GAD-7 to screen for anxiety severity as part of your intake assessment. Those results, along with your substance use history, shape a treatment plan that addresses both together.

Which mental health conditions do you treat alongside addiction?

Depression and anxiety are the two conditions we formally screen for with the PHQ-9 and GAD-7, and treatment addresses whichever mental health symptoms are contributing to or complicating your substance use. Your assessment determines the specific focus of care.

Will my psychiatric medication be changed when I start treatment here?

Not without a clinical reason and a conversation with you first. Existing psychiatric medication is reviewed as part of your intake, and any changes are made deliberately, not automatically.

Is dual diagnosis treatment available by telehealth?

Telehealth is generally available as part of how care is delivered here. We work out which sessions make sense in person versus by telehealth based on your treatment plan.

Does treating my mental health slow down my addiction treatment?

No — the two run together rather than one waiting on the other. Trying to treat addiction while an untreated mental health condition keeps driving use tends to fail, which is exactly why they're addressed as one plan.
