Substance Use Disorder Care Management

Substance use disorder (SUD) care management is a structured clinical and coordination function that applies evidence-based frameworks to support individuals with alcohol, opioid, stimulant, or other drug-related disorders across the continuum of care. This page covers the regulatory context, operational mechanisms, clinical scenarios, and professional decision boundaries that define SUD care management as a distinct specialty within behavioral and integrated health services. The subject carries significant public health weight: the Substance Abuse and Mental Health Services Administration (SAMHSA) reported that 48.7 million people aged 12 or older met criteria for a substance use disorder in 2022 (SAMHSA 2023 National Survey on Drug Use and Health). Effective care management in this population reduces emergency department utilization, supports medication-assisted treatment adherence, and bridges gaps between acute detoxification and long-term recovery infrastructure.

Definition and Scope

SUD care management is a subset of behavioral health care management that operationalizes coordinated, longitudinal support for individuals whose primary or comorbid diagnosis involves a substance use disorder as classified under the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), published by the American Psychiatric Association. DSM-5 classifies SUDs along a severity continuum — mild, moderate, and severe — based on the number of diagnostic criteria met within a 12-month period, ranging from 2–3 criteria (mild) to 6 or more (severe).

The regulatory scope of SUD care management is shaped by three primary federal frameworks:

• 42 CFR Part 2 — Federal regulations governing the confidentiality of substance use disorder patient records, administered by the Substance Abuse and Mental Health Services Administration (SAMHSA). These rules impose stricter consent requirements than standard HIPAA protections for most health data (42 CFR Part 2, eCFR).
• Mental Health Parity and Addiction Equity Act (MHPAEA) — Federal law requiring insurers to provide SUD benefits at parity with medical/surgical benefits, enforced by the Departments of Labor, Treasury, and Health and Human Services (MHPAEA, CMS).
• 21st Century Cures Act — Provisions under this legislation expanded access to medication-assisted treatment (MAT) and modified 42 CFR Part 2 consent requirements to facilitate care coordination.

SUD care management intersects with complex care management when co-occurring chronic conditions — such as hepatitis C, HIV, or cardiovascular disease — are present alongside the primary substance use disorder.

How It Works

SUD care management follows a structured, phase-based process. While specific models vary by payer and provider setting, the core operational sequence aligns with standards described by SAMHSA's Treatment Improvement Protocol (TIP) Series, particularly TIP 27 (Comprehensive Case Management for Substance Abuse Treatment):

• Screening and Identification — Validated tools such as the AUDIT-C (Alcohol Use Disorders Identification Test — Consumption) or the DAST-10 (Drug Abuse Screening Test) are used to identify individuals who meet SUD criteria or are at elevated risk. Risk stratification in care management frameworks classify SUD severity to prioritize care management intensity.
• Assessment — A biopsychosocial assessment captures diagnostic status, co-occurring mental health conditions, housing stability, social support, and treatment history. SAMHSA's ASAM Criteria (American Society of Addiction Medicine) provide a six-dimension assessment framework widely adopted for level-of-care placement decisions.
• Care Plan Development — A person-centered care plan is developed in alignment with the individual's treatment goals, integrating MAT (e.g., buprenorphine, naltrexone, methadone), behavioral therapies, and recovery support services. Standards from the patient-centered care planning framework apply throughout this phase.
• Care Coordination and Navigation — The care manager facilitates referrals to outpatient, intensive outpatient (IOP), residential, or medically managed intensive inpatient settings as determined by ASAM level-of-care criteria. Coordination includes communication with prescribing providers, behavioral health clinicians, and community support programs.
• Monitoring and Reassessment — Ongoing monitoring tracks treatment engagement, relapse events, medication adherence, and changes in social determinants. Social determinants of health in care management — including housing insecurity and food access — are formally assessed as drivers of SUD relapse risk.
• Transition and Step-Down — As clinical stability is achieved, care intensity is adjusted. Transitional care management protocols govern transitions between inpatient detoxification and community-based recovery programs.

Common Scenarios

SUD care management is activated across a range of clinical and administrative triggers. The most operationally frequent include:

• Post-overdose care coordination — Following emergency department treatment for opioid overdose, care managers initiate warm handoffs to MAT providers. The CDC has documented opioid overdose as a leading cause of injury death in the United States, with 80,411 opioid-involved overdose deaths recorded in 2021 (CDC, Drug Overdose Surveillance).
• Dual-diagnosis management — Individuals with co-occurring SUD and a major depressive, anxiety, or psychotic disorder require integrated care planning that addresses both diagnostic domains simultaneously. This scenario is central to integrated care management models.
• Medicaid managed care enrollment — State Medicaid programs increasingly embed SUD care management within managed care organization (MCO) benefit designs. Medicaid care management programs define eligibility, authorization, and reporting standards for this population at the state level.
• Pregnant individuals with SUD — Opioid use disorder during pregnancy requires specialized protocols, including coordination with obstetric providers and neonatal teams. Federal guidance from SAMHSA's TIP 63 (Medications for Opioid Use Disorder) addresses this subset directly.
• Workplace re-entry and EAP-referred cases — Employee Assistance Program referrals route individuals into SUD care management following workplace incidents. Confidentiality under 42 CFR Part 2 governs information sharing in this context.

Decision Boundaries

SUD care management operates within defined professional and regulatory limits that distinguish it from clinical treatment.

Care management versus clinical treatment: A care manager coordinates, monitors, and facilitates access to treatment but does not diagnose, prescribe, or deliver psychotherapy. Prescribing of MAT medications (buprenorphine, methadone) requires licensure under the Drug Enforcement Administration (DEA) and, for methadone in opioid treatment programs, compliance with 42 CFR Part 8 (eCFR 42 CFR Part 8).

Confidentiality boundaries: Unlike standard HIPAA-governed records, SUD treatment records subject to 42 CFR Part 2 require explicit patient consent before disclosure to most third parties, including other treating providers, unless specific exceptions apply. Care managers must maintain operationally separate consent workflows for SUD records versus general medical records. The HIPAA and care management privacy framework does not subsume 42 CFR Part 2 obligations.

Level-of-care determination: Care managers do not unilaterally determine ASAM level-of-care placement. That clinical determination rests with licensed clinicians. Care managers implement and coordinate the placement decision, track adherence, and escalate when the individual's condition does not match the assigned level of care. Utilization management decisions in this process fall under the utilization management in healthcare function.

Credential boundaries: The Commission on Case Manager Certification (CCMC) and the National Association of Social Workers (NASW) both publish scope-of-practice guidance relevant to SUD care management. The Certified Case Manager (CCM) credential from CCMC does not independently authorize clinical practice; state licensure requirements govern what functions a given professional can perform within SUD care management roles.
