A co-occurring disorder means a mental health condition and a substance use disorder are present at the same time. This page approaches that from the mental health side: you came in for depression, anxiety, bipolar disorder, or trauma, and substance use turned out to be part of the picture.

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

How the two tracks fit together

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.

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

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 treating one and referring out the other tends to fail

The two conditions interact. Drinking to quiet anxiety works for an evening and raises anxiety for the following two days. Depression lowers the resources you need to stop using; withdrawal deepens depression. Treat either one in isolation and the untreated condition keeps pulling the other back down, which is why people cycle through programs and conclude that treatment does not work for them.

Integrated care means one clinical team holds both pictures at once — one assessment, one treatment plan, medication decisions that account for both, and no requirement to get sober before your mental health condition is taken seriously.

What treatment looks like

Assessment

One evaluation covering psychiatric symptoms, substance use, medical history, medication, and safety. We do not try to settle which condition came first before starting treatment — that question is often unanswerable and rarely changes what needs to happen next. 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

If withdrawal management is needed, that comes first, through our outpatient detox under DHCS certification 370254AP. Alongside it, sleep, routine, and psychiatric stabilization. When housing is part of the instability, addiction and mental health housing options are part of the plan.

Active treatment

Mental health programming at the PHP or IOP level under the County contract, coordinated with substance use programming at the outpatient, intensive outpatient, or medication-assisted treatment level. Where medication for opioid or alcohol use disorder is indicated, it is managed alongside psychiatric medication rather than in a separate silo.

Step-down

Care steps down as stability holds, with a plan that names both sets of warning signs — because a return of depression and a return to using are each capable of setting off the other.

Questions, Answered

Frequently asked questions

Do I have to be sober before you will treat my mental health condition?
No. Both conditions are treated at the same time by one clinical team. Requiring sobriety first is the ordering that most often fails people with co-occurring conditions.
Is there a PHP for substance use?
No. Our Partial Hospitalization Program is a specialty mental health service under County Contract 575462. Substance use care is provided at the detox, outpatient, intensive outpatient, and medication-assisted treatment levels under DHCS certification 370254AP. One clinical team coordinates both.
How is this page different from your dual diagnosis page?
Only in where you started. This page frames the same coordinated care from the mental health side; our <a href="/treatment-programs/dual-diagnosis/">dual diagnosis page</a> frames it from the addiction side.
Which condition gets treated first?
Neither, in the sense of one waiting. Sequencing is clinical: withdrawal management comes first if it is medically needed, and psychiatric stabilization runs alongside it rather than after it.
Does Medi-Cal cover co-occurring treatment?
Yes. Specialty mental health services and Drug Medi-Cal Organized Delivery System services are both administered by San Diego County Behavioral Health Services, so both sides of your care can be covered at no cost to you on any Medi-Cal plan in the county.
How common is it to have both a mental health condition and a substance use disorder?
It's common, and getting more so: San Diego County's Health and Human Services Agency found that 60% of adult and older-adult clients in the public behavioral health system had both a mental illness and a substance use disorder in fiscal year 2020-21, a five-point climb from FY 2016-17. Nationally, SAMHSA's 2022 survey found nearly half of young adults aged 18 to 25 (48.8%) had either condition in the past year. Co-occurring conditions are treated together in our dual-diagnosis programming rather than as separate tracks.
What counts as a co-occurring disorder?
A co-occurring disorder means a mental health condition and a substance use disorder are present at the same time, such as depression alongside alcohol use. Your intake assessment screens for both so your treatment plan addresses the full picture.
Do you treat both conditions in the same sessions, or separately?
Treatment is coordinated so that your mental health and substance use symptoms are addressed together rather than in disconnected tracks, since the two often influence each other. Your care team designs your plan around how your specific conditions interact.
What if my substance use is more of a concern than my mental health right now?
Your intake assessment evaluates both conditions regardless of which one feels more urgent to you, since untreated symptoms on either side can affect the other. Your treatment plan reflects what the assessment identifies as clinically necessary.
Can I start treatment if I'm not ready to fully stop using?
Intake assessment considers where you are in your process; discuss your current situation openly with our admissions team so your treatment plan reflects your actual starting point.
How do you decide which level of care fits a co-occurring presentation?
The level of care is determined clinically during intake, based on the severity of both your mental health and substance use symptoms together, not by either condition alone.
What if I've only ever been treated for one of the two conditions before?
That's common, and it's useful information for your intake assessment. Your care team will evaluate the condition that hasn't been addressed yet alongside the one that has, so your treatment plan covers both.
