Integrated Treatment for Co-Occurring Disorders

Integrated Treatment for Co-Occurring Disorders (IT-COD) is considered an evidence-based practice because research shows in contrast to the “system as usual” approach, individuals with co-occurring disorders experience improved treatment outcomes when they receive this holistic, specialized form of treatment. In this model, the contributions of professionals from both the mental health and substance use fields are merged into a single treatment regimen and setting. Minnesota Rule 9533.0010, Applicability subp. 2. Optional Certification, briefly describes how this rule is a supplemental or “add on rule.” This means the certification is supplemental to a pre-existing authorization by the department (or other governing body) to operate a previously existing mental health or chemical dependency service. Thus, the new rule adds a supplemental layer of specialized requirements focused solely on the provider’s IT-COD program. Minnesota Rules, parts 9533.0010 to 9533.0180 describe IT-COD in its entirety. 

What services are available?  
Minnesota Rule 9533.0060 Program Structure and Practice Principles identify the various components of IT-COD. 

Who is eligible for this service? 
The target population is defined in Minnesota Rule 9533.0040 Target Population.

Current providers 
Certification is voluntary. At this time individual and program certifications are being developed. When a program is IT-COD certified, the new rule requirements supersede any previously existing department rule requirements as IT-COD establishes a higher standard of care than other rules. Eligibility for certification is provided in Minnesota Rule 9533.0030 Eligibility for Certification.

Currently, there is not a procedure-specific code for IT-COD. Agencies providing IT-COD counseling techniques use traditional mental health codes such as a diagnostic assessment (an extended diagnostic assessment allows for payment of a more extensive, in-depth assessment of the two disorders) and individual and group psychotherapy. DHS will be evaluating how IT-COD services fit within the new chemical dependency rate structure for co-occurring services. The legislature did not appropriate funds for integrated dual diagnosis treatment, but directed the department to “apply for any federal waivers necessary to secure, to the extent allowed by law, federal financial population. Minnesota Statutes, section 245.4863, paragraph (c). Review is underway to seek this federal financial participation. Until that occurs, reimbursement for integrated dual diagnosis treatment will occur based on the traditional reimbursement categories for discrete mental health and chemical dependency treatment services. 

Reporting requirements 
As certified programs are implemented across the state, the department will obtain valuable treatment outcomes data from these programs, which will help refine the fluid process of creating individual and program certifications for IT-COD. The department will analyze the data to identify patterns and seek to further improve health care outcomes for the individuals served in these programs. At this time, Minnesota Rule 9533.0160 Quality Assurance and Improvement, outlines basic guidelines for reporting and data collection. In addition, all participants are required to report client-level data to MHIS (Mental Health Information System)
