New SAMHSA Guide Highlights HIV Prevention and Treatment for People with Substance Use and/or Mental Disorders
Impact on your practice
This SAMHSA clinical guidance can help therapists improve outcomes for high-risk populations with co-occurring conditions. It may also inform insurance companies' expectations for evidence-based treatment, potentially affecting prior authorization decisions.
Key facts
SAMHSA released evidence-based guidebook on HIV prevention and treatment for people with co-occurring SUD and/or mental disorders
Addresses integrated care approaches for complex populations at highest risk
Provides therapists with evidence-based practices for co-morbid HIV/MH/SUD clients
Free resource available from SAMHSA store; likely to influence clinical standards of care
Therapy Companion analysis
This SAMHSA guidebook establishes evidence-based standards of care for a population you're increasingly likely to treat: patients with concurrent HIV, mental health conditions, and/or substance use disorders. As a therapist, understanding these integrated care expectations positions you defensively against insurance denials. Payers—particularly Medicaid programs—will increasingly reference SAMHSA guidance when evaluating medical necessity for your sessions. If your documentation doesn't align with these evidence-based approaches, you risk prior authorization denials or retroactive claim reductions, especially when treating patients with co-occurring conditions. The guide legitimizes longer treatment episodes and more frequent sessions for this complex population, giving you clinical justification during peer-to-peer reviews. For practitioners working in community mental health centers, SUD treatment programs, or HIV specialty clinics, this guidance directly impacts your billing strategy: you can now cite federal standards when arguing for extended treatment timelines that insurance companies initially question. Your individual session notes should increasingly reference the integrated assessment principles outlined in SAMHSA resources, demonstrating you're following federal clinical standards rather than simply billing for generic therapy. This is particularly important for Medicaid providers, since state Medicaid programs often adopt SAMHSA guidance as their own clinical standards.
Background
The federal government has prioritized HIV prevention and treatment integration since the Ending the HIV Epidemic (EHE) initiative launched in 2019. This 2021 SAMHSA guidebook operationalizes that priority by providing therapists with concrete evidence-based practices for the subset of HIV patients with concurrent psychiatric and/or substance use conditions—a population with historically worse outcomes and higher healthcare costs. Mental illness and SUD approximately double the risk of HIV acquisition and significantly reduce treatment adherence for those already diagnosed. SAMHSA released this resource because siloed treatment (mental health therapy separate from HIV medical care, separate from addiction treatment) has consistently failed this population. The federal government recognizes that achieving the EHE goal of reducing new infections by 90 percent by 2030 requires therapists and counselors to operate within an integrated framework rather than in traditional disciplinary silos.
What you should do
Download the SAMHSA guidebook from the SAMHSA store and review the modules relevant to your current client population. Flag which integrated care principles you're not currently documenting, then revise your intake and ongoing assessment templates to capture co-occurring risk factors across HIV/mental health/SUD domains.
Audit your last 20 sessions with clients who have co-occurring mental health and substance use conditions (regardless of HIV status) and identify gaps between your current documentation and the evidence-based practices outlined in the SAMHSA guide. Update your clinical notes retroactively if necessary to ensure parity with federal standards.
For your next insurance prior authorization request involving a client with any combination of HIV, mental illness, and/or SUD, explicitly cite SAMHSA's Prevention and Treatment of HIV Among People Living with Substance Use and/or Mental Disorders as the clinical standard supporting your proposed treatment plan. This defensively positions you before payer denial.
If you bill Medicaid, contact your state Medicaid agency to determine whether they have adopted SAMHSA guidance into their clinical standards for HIV/mental health/SUD co-occurring conditions. Some states have; others haven't yet. Knowing your state's position informs your documentation and appeal strategy.
Assess your referral network for gaps in integrated care. SAMHSA guidance assumes therapists work collaboratively with HIV specialists and addiction medicine providers. If your practice lacks formal co-treatment agreements or warm handoff protocols with these disciplines, establish them now to align with federal standards that payers will increasingly enforce.

"Mental illness and SUD are linked to behaviors that can increase a person's likelihood of getting HIV and can negatively impact HIV care, treatment, and related health outcomes." (HHS/SAMHSA, February 2021)
"A priority topic for SAMHSA is preventing HIV among people with mental illness and/or SUD and linking people with HIV and co-occurring mental illness and/or SUD to HIV care." (SAMHSA, 2021)
