Co-occurring disorders — also called dual diagnosis — affect millions of people dealing with both a mental health condition and a substance use disorder at the same time. At Prosperous Health San Diego, our integrated treatment model addresses both conditions simultaneously so you can achieve lasting, whole-person recovery.
Mental health conditions, substance use disorders, and the complex relationship between them all require care at the same time. When you treat only one condition, the other goes unaddressed — and recovery is rarely sustained. That’s why the San Diego Transformation Center specializes in integrated dual diagnosis care that treats both simultaneously.
Nearly half of all people with a substance use disorder also live with a mental health condition. These aren’t separate problems — they interact, reinforce, and worsen each other over time. Addressing both conditions together is the only approach proven to support lasting recovery.
Common combinations include:
These conditions don't exist in isolation—they interact, trigger, and complicate each other. That's why integrated treatment is essential.
We offer dual diagnosis treatment at every level. Each level provides
the same coordinated approach with intensity adjusted to your needs.
Partial Hospitalization Program (5-6 hours daily): Intensive integrated treatment for complex or acute co-occurring conditions
Intensive Outpatient Program (3 hours, 3-5 days/week): Structured support while maintaining daily responsibilities
Outpatient Program (1-2 sessions/week): Ongoing integrated care for sustained recovery
Clinical Services: Dual diagnosis assessment, individual therapy for both conditions, specialized co-occurring disorder groups, family education about dual diagnosis, medication management and monitoring
Therapeutic Interventions: Integrated CBT for co-occurring disorders, trauma-informed care, emotion regulation skills, relapse prevention for both conditions, mindfulness and distress tolerance
Support Services: Case management, peer support from others with dual diagnosis, connection to community resources, comprehensive discharge planning
Co-occurring disorders often create a destructive pattern — mental health symptoms trigger substance use, and substance use worsens mental health. Without integrated care, this cycle tends to repeat despite treatment efforts.
Our program is designed specifically to interrupt this cycle. We identify triggers, build coping skills, and create a recovery plan that supports your total wellness — not just one part of it.
You may benefit from co-occurring disorders treatment if you’ve experienced mental health symptoms alongside substance use, struggled with relapse after single-condition treatment, or felt that one issue always seems to bring back the other. Many people don’t realize their addiction and mental health are connected until a comprehensive assessment reveals the full picture.
Prosperous Health San Diego offers a thorough dual diagnosis evaluation to help identify all conditions that need to be addressed. The right diagnosis leads to the right treatment — and better outcomes.
Many major insurance plans cover dual diagnosis treatment, including care for both mental health and substance use disorders. Prosperous Health San Diego works with most major insurance providers to help reduce your out-of-pocket costs.
You can verify your coverage directly on our website in minutes. Our admissions team is also available to walk you through your benefits and explain what your plan covers at the PHP, IOP, or OP level.
Reaching out is the hardest step — and we make it as simple as possible. When you contact our admissions team, you’ll speak with a caring professional who will listen without judgment and answer your questions honestly.
We’ll gather basic information, conduct a brief screening, and recommend the most appropriate level of care for your situation. Same-day assessments are often available for those ready to begin.
A co-occurring disorder, also called a dual diagnosis, is when a person experiences a mental health condition (such as depression, anxiety, bipolar disorder, or PTSD) and a substance use disorder at the same time. The two conditions often influence each other, so the most effective care treats both together rather than separately.
At San Diego Transformation Center, dual diagnosis treatment combines psychiatric care, medication management, individual and group therapy, and substance use treatment in one coordinated outpatient program. Because mental health and addiction care are delivered by the same team in one location, your plan addresses both conditions in parallel.
Standard addiction treatment focuses primarily on substance use. Co-occurring disorders treatment adds integrated mental health care—diagnosis, therapy, and medication management for the underlying condition—so untreated symptoms don’t undermine recovery. Integrated care is associated with more stable, lasting outcomes.
Yes. We offer a Partial Hospitalization Program (PHP) and an Intensive Outpatient Program (IOP) for co-occurring disorders, along with a step-down Outpatient Program (OP). Your level of care is matched to your clinical needs and can change as you progress.
We commonly treat depression, anxiety, bipolar disorder, PTSD and trauma, and other mood disorders alongside substance use. Our clinical team builds a personalized plan based on a full assessment.
Many PPO and in-network plans cover co-occurring disorders treatment. You can verify your benefits confidentially through our insurance verification page, and our team will explain what your plan covers.
If you’re managing both a mental health condition and substance use—or past treatment addressed only one and symptoms returned—dual diagnosis care may be a better fit. A clinical assessment can clarify the right level and type of treatment for you.
