Substance Use Disorder Documentation Guide

Why Diagnosis-Specific Documentation for Substance Use Disorders Matters

Substance Use Disorders are heavily scrutinized by payers because care can span multiple levels of intensity and because authorization often hinges on demonstrating the right level of care. Reviewers know what good SUD documentation looks like, and they expect notes that reflect the specific clinical picture — substance, use pattern, severity, and stage of change — not generic language about "working on sobriety." Diagnosis-specific documentation is how you demonstrate that the services you bill are reasonable and necessary for this client's substance use.

This page is a hub. It does not replace your treatment plan or your progress notes; it points you to the templates and references already in this library and teaches the SUD-specific clinical language that ties them together. The goal is a defensible record where the diagnosis, the use pattern, the impairment, the level of care, and the interventions all clearly connect — the "golden thread" that survives a utilization review.

Documentation Resources for Substance Use Disorders

Use these existing library resources to assemble a complete, defensible substance use record:

• Substance Use Treatment Plan — a full treatment plan template with SMART goals, measurable objectives, and relapse-prevention interventions for SUD, including a filled-in clinical example.
• Substance Use Progress Notes — session-note examples with disorder-specific language for documenting use pattern, stage of change, interventions delivered, and response to treatment.
• Substance Abuse Assessment — a structured assessment format for documenting use history, severity, prior treatment, and the multidimensional information that supports a level-of-care decision.
• Motivational Interviewing Documentation — how to document MI techniques (reflective listening, eliciting change talk, rolling with resistance) that form a core evidence base for SUD treatment.

ICD-10 Codes for Substance Use Disorders

ICD-10 organizes substance use codes by substance class and by the use, dependence, and remission structure. Select the code that matches your documented criteria count, the substance involved, and the client's current remission status.

• F10.20 — Alcohol Use Disorder, Moderate (Dependence) — alcohol dependence, uncomplicated; use when the client meets criteria for moderate alcohol use disorder without current intoxication or withdrawal coded separately.

Codes for other substance classes follow the same structure (for example, the F11 series for opioids and F12 for cannabis). Document the substance, the severity, and whether the client is in early or sustained remission so the code you assign matches the clinical record.

Clinical Language and Symptoms to Document

Auditors and reviewers look for the language of substance use disorders, not vague references to "sobriety." Anchor your documentation in the disorder-specific terms below, and describe each in observable, measurable terms rather than as labels.

• Use pattern — document substance, frequency, quantity, route, and most recent use ("daily alcohol use, approximately 8-10 standard drinks, last use two days ago"), not just "drinking too much." Note tolerance and withdrawal where present.
• Stage of change — name the client's stage explicitly (precontemplation, contemplation, preparation, action, maintenance). This frames the goals and justifies a motivational approach when the client is not yet committed to abstinence.
• Cravings and triggers — document craving intensity, frequency, and the specific situational, emotional, or interpersonal triggers identified.
• Relapse prevention — document the relapse-prevention skills targeted (trigger identification, coping strategies, refusal skills, lapse-versus-relapse planning) and the client's use of them between sessions.
• Motivational interviewing — when you describe what you did, use precise MI terms such as eliciting change talk, rolling with resistance, and developing discrepancy, so the note reflects skilled clinical work.
• ASAM level of care — reference the ASAM dimension findings that justify the intensity of treatment (for example, outpatient versus intensive outpatient).
• Harm reduction versus abstinence — document the client's stated goal and whether the approach is harm reduction or abstinence-based, so the plan reflects collaborative, client-centered objectives rather than a single imposed standard.

Screening and Outcome Measures

Standardized measures turn subjective impressions into trackable data and are among the strongest evidence of medical necessity and progress.

• AUDIT — the Alcohol Use Disorders Identification Test. Administer at intake and at intervals for alcohol use. Record the numeric score (0-40) and risk band in both the treatment plan and progress notes (for example, "AUDIT = 22, high-risk / probable dependence"), and document the score trend over time.
• DAST-10 — the Drug Abuse Screening Test. Use for non-alcohol substances; record the 0-10 score and the date administered. Note which substances the screen reflects.
• ASAM criteria — document a multidimensional assessment across the ASAM dimensions (intoxication/withdrawal potential, biomedical conditions, emotional/behavioral conditions, readiness to change, relapse potential, and recovery environment). The resulting level-of-care recommendation is what most payers expect to see when authorizing SUD treatment.

When you reference a measure, record who administered it, the date, the score, and how the result informed your clinical decision-making and level-of-care recommendation.

Documenting Medical Necessity for Substance Use Disorders

Medical necessity is established by a clear chain connecting documented use pattern, the impairment that use causes, and the interventions delivered at an appropriate level of care. This is the golden thread.

Start with the diagnosis and its supporting evidence — the DSM-5 criteria the client meets, the ICD-10 code, a current AUDIT or DAST score, and an ASAM level-of-care determination. Then translate use into functional impairment in concrete terms: "lost employment after a positive workplace test and has two pending charges" is far stronger than "use is causing problems." Finally, show that each active intervention targets a documented problem: motivational interviewing addresses ambivalence and stage of change, relapse-prevention work addresses identified triggers and cravings, and the ASAM rationale justifies the treatment intensity. Every session note should show movement along this chain — what was targeted, what skilled intervention was delivered, and how the client responded.

Common Documentation Mistakes

• Breaking the golden thread. Listing relapse prevention or motivational interviewing in the treatment plan but never describing them in progress notes — or documenting interventions with no link to a stated goal — is the single most common audit finding for SUD.
• No level-of-care rationale. Billing intensive outpatient or a higher level of care without an ASAM multidimensional assessment to justify the intensity invites denials. Document the dimensions and the resulting recommendation.
• Treating relapse as failure or omitting it. Failing to document a clear return to use, or framing it as the client "not trying," leaves a defensibility gap. Record the episode, the triggers, the stage of change, and your skilled clinical response.
• Imposing abstinence without the client's goal. Documenting abstinence as the only objective when the client's stated goal is harm reduction breaks the collaborative thread and weakens both engagement and the medical-necessity narrative. Record the client's actual goal and the chosen approach.
