A biopsychosocial assessment is the intake evaluation of a person's biological, psychological and social history, and it's the document the diagnosis and treatment plan rest on. In behavioral health (BH) and substance use disorder (SUD) programs it should cover 16 domains, from a quantified substance use history to risk and a diagnostic impression, ending in a level-of-care recommendation. State licensing rules set who completes it and how fast. Auditors ask one thing: does every later decision trace back to it?
This guide covers who may complete it, timing rules from several states and federal programs, what to document in each domain, the ASAM mapping, sample entries, reassessment, 42 CFR Part 2 and common audit findings. For what payers expect after intake, see our medical necessity documentation guide.
The short version
- The assessment is the source document for the diagnosis and the treatment plan, including the ASAM level of care. A plan problem with no matching finding stands out in any review.
- Deadlines vary: 5 days for licensed SUD programs in Minnesota, 3 to 30 days by level of care in Florida, 14 days for opioid treatment programs, and no fixed count for California Medi-Cal programs since 2024.
- Quantify substance use: amount, frequency, route, last use and withdrawal history.
- Use a validated suicide screen and document the risk level and plan. Joint Commission-accredited BH programs must screen everyone served age 12 and older.
- At a Part 2 program the assessment is a Part 2 record. Since February 16, 2026, one patient consent can cover all future treatment, payment and health care operations uses.
- Reassess when something changes, and never carry old text forward unchanged.
What the assessment is for, and who may complete it
First Coast's Medicare policy for psychiatric services (LCD L33252) calls the psychiatric diagnostic evaluation "an integrated biopsychosocial assessment": medical, family and social history, psychiatric history, a mental status exam and a tentative diagnosis. Depending on the payer, it's billed as 90791 or as a Medicaid HCPCS code such as H0001 (alcohol and/or drug assessment) or H0031 (mental health assessment by a non-physician). Our guide to psychotherapy codes and 90791 covers the coding side.
Whatever the code, the assessment has four jobs: support the diagnosis, justify the level of care through a risk rating in each ASAM dimension, set the baseline for measuring progress, and give every treatment plan problem a finding to point back to.
State law decides who may complete it, and SUD and mental health rules can differ inside one state. Two examples:
Minnesota. Licensed SUD programs may use alcohol and drug counselors, mental health professionals or advanced practice registered nurses with at least 12 hours of SUD training, or clinical trainees under supervision (Minn. Stat. 245G.05). The assessment is complete only when a qualified staff member signs and dates it. A mental health diagnostic assessment is narrower: only a mental health professional or a clinical trainee may complete it (245I.10).
Florida. Clinical staff complete the psychosocial assessment, but if the author isn't a qualified professional, one must countersign and date it within 10 calendar days (Fla. Admin. Code 65D-30.0042). Qualified professionals include physicians and physician assistants, psychologists, clinical social workers, marriage and family therapists, mental health counselors, APRNs, and certified addiction professionals with at least a bachelor's degree (s. 397.311).
My view: let trained intake staff gather the history, but have a licensed clinician own and sign the diagnostic impression and the level-of-care recommendation. Diagnosis has to sit inside someone's licensed scope, and that's the line reviewers check first.
How soon it must be done
There's no national deadline. The clock comes from your license and your funding source, and it runs from 60 hours to 60 days:
| Rule | Who it covers | Deadline |
|---|---|---|
| Minn. Stat. 245G.05 | Licensed SUD programs | 5 calendar days from service initiation (residential), or by the fifth day a treatment service is provided (nonresidential). A late assessment needs a documented reason and a planned date. |
| Fla. Admin. Code 65D-30.0042 | Licensed SUD services | 3 calendar days (receiving facilities, intensive inpatient), 5 (residential level 1), 10 (residential levels 2 to 4, day or night treatment), 15 (methadone), 30 (intensive outpatient and outpatient) |
| California DHCS BHIN 23-068 | Medi-Cal mental health and Drug Medi-Cal | No fixed count since January 1, 2024. Assessments are due "as expeditiously as possible," in line with clinical need. |
| 42 CFR 8.12(f)(4) | Opioid treatment programs | Full initial psychosocial assessment within 14 calendar days of admission |
| 42 CFR 482.61(b) | Medicare psychiatric hospitals | Psychiatric evaluation within 60 hours of admission |
| SAMHSA CCBHC criteria | Certified community behavioral health clinics | Initial evaluation within 10 business days (1 if urgent), full evaluation within 60 calendar days of the first request |
Accreditors' free materials set content, not a day count. The Joint Commission's behavioral health standards sampler says a complete and accurate assessment drives the services delivered (CTS.02.02.03), and requires screening for imminent risk of harm and identifying people who may have experienced trauma. CARF puts assessment in Section 2.B of its Behavioral Health manual, Screening and Access to Services. Both manuals are licensed, so check the edition you're surveyed against.
Pick one internal deadline: the strictest rule that applies, and always before the first treatment plan is due. Minnesota's 10-day residential plan deadline (245G.06) only works if the assessment lands first.
What to include: 16 domains, and what auditors flag
State lists overlap more than they differ. Florida's rule requires 15 psychosocial items, and the SAMHSA CCBHC criteria list 15 for the full evaluation (4.d.4). Merged, they make these 16 domains.
| Domain | What to document | What auditors flag |
|---|---|---|
| Presenting problem | Reason in the person's words, onset, severity, what led to admission, referral source | Referral reason only ("court ordered") |
| Psychiatric history | Diagnoses, hospitalizations, past treatment and what helped, suicide attempts | "Hx of depression," no dates or outcome |
| Substance use history | Per substance: age of first use, amount, frequency, route, last use (date and time), withdrawal history including seizures, overdoses, prior treatment | "Uses meth daily," no route, amount or last use |
| Medical | Current conditions, recent hospital stays, pregnancy, infectious disease screening | "No medical issues," no screening shown |
| Medications | Prescriptions, over-the-counter drugs, supplements, MOUD, allergies, PDMP check where used | No doses, or a list that conflicts with the medical section |
| Trauma | Standardized exposure screen, current trauma-related symptoms | Skipped with no reason. Minnesota (245I.10) lets you defer it if asking would retraumatize, but you must say so. |
| Family and social | Family history of mental illness and substance use, supports, children and custody | No named supports |
| Legal | Charges, probation or parole, court dates, child welfare involvement | "Legal issues," no status |
| Education and employment | Education, literacy, work, income, military service | Employment status only |
| Housing | Living situation, stability, substance use in the home | "Lives with friend," nothing on fit for recovery |
| Cultural and spiritual | Language needs, cultural factors that affect care, faith or values | A box ticked "none" |
| Strengths and preferences | Strengths, goals and treatment preferences in the person's words | "Motivated," repeated across patients |
| Risk and safety | Validated suicide screen, assessment if positive, violence and partner violence risk, overall risk level, mitigation plan | No validated tool, or a positive screen with no plan |
| Mental status | Appearance, behavior, speech, mood, affect, thought, perception, cognition, insight, judgment | "MSE WNL" |
| Diagnostic impression | DSM-5-TR diagnoses with the criteria met, specifiers, rule-outs, ICD-10-CM codes | A diagnosis with no supporting symptoms |
| Recommendations | Level of care with dimensional rationale, services, referrals, why a lower level won't work | "IOP recommended," no reason |
Two domains carry the most weight. The substance use history decides SUD claims. A daily quantity and a last-drink time, next to a past withdrawal seizure, can justify withdrawal management on their own. "Daily alcohol use" justifies nothing.
Risk now has a hard floor. The Joint Commission's NPSG.15.01.01, effective January 2026 for behavioral health care and human services, requires a validated suicide screen for everyone served from age 12. A positive screen calls for an evidence-based assessment that asks directly about ideation, plan, intent, behaviors, risk factors and protective factors, followed by a documented risk level and mitigation plan.
Mapping the assessment to the six ASAM dimensions
SUD level-of-care decisions run through the ASAM Criteria. The Fourth Edition, released in 2023, renamed and reordered the dimensions and replaced Readiness to Change with a new Dimension 6, Person-Centered Considerations. States are moving at different speeds. Minnesota's statute still uses Third Edition-style names (254B.04) and requires every SUD assessment to include a risk rating with a supporting summary for each dimension, plus a recommended ASAM level (245G.05).
| Fourth Edition dimension | Third Edition name | Domains that feed it |
|---|---|---|
| 1. Intoxication, Withdrawal, and Addiction Medications | Acute intoxication and/or withdrawal potential | Substance use history, last use, withdrawal history, MOUD, withdrawal scale scores |
| 2. Biomedical Conditions | Biomedical conditions and complications | Medical, medications, pregnancy, sleep |
| 3. Psychiatric and Cognitive Conditions | Emotional, behavioral, or cognitive conditions and complications | Psychiatric history, trauma, mental status, risk, cognitive screening |
| 4. Substance Use-Related Risks | Relapse, continued use, or continued problem potential | Use pattern, return-to-use and overdose history, high-risk behaviors |
| 5. Recovery Environment Interactions | Recovery/living environment | Housing, family and social, legal, employment, cultural perceptions of substance use |
| 6. Person-Centered Considerations | New (Readiness to change was Dimension 4) | Strengths and preferences, barriers to care, motivation |
Use the names your payers use, and write the rating before the reason. A high Dimension 1 rating with no last-use time behind it is how level-of-care denials start. Our ASAM level of care documentation guide covers payer expectations by level, and the free ASAM documentation checklist turns them into a pre-signature check.
How the assessment feeds the treatment plan and medical necessity
The rules agree here. Minnesota requires the SUD treatment plan to be based on the assessment (245G.06), the CCBHC criteria require a plan built from the full evaluation (4.e.2), Medicare psychiatric hospitals need a plan based on an inventory of the patient's strengths and disabilities (42 CFR 482.61(c)), and the Joint Commission wants a plan that reflects assessed needs, strengths, preferences and goals (CTS.03.01.03).
CARF programs call the bridge the interpretive summary, and Florida requires a clinical summary with analysis and interpretation. Whatever you call it, write it. It's the paragraph a reviewer reads first.
Here's the chain a reviewer follows, for a fictional patient:
- Finding. About 12 standard drinks a day for 8 months, last drink 6 hours before intake, one withdrawal seizure two years ago.
- Diagnosis. Alcohol use disorder, severe, with each criterion met listed in the record.
- Rating. High risk in Dimension 1 because of the seizure history and current heavy use.
- Level of care. Withdrawal management with medical monitoring, and why outpatient withdrawal isn't safe for this person.
- Plan problem and goal. Complete withdrawal safely, tracked by withdrawal scale scores, then reassess for the next level.
Break any link and medical necessity gets argued on the payer's terms instead of yours. If you're rebuilding the plan form too, start from our SUD treatment plan template.
Weak vs strong entries: sample language
Every example below is fictional and written for illustration only.
| Domain | Weak entry | Strong entry |
|---|---|---|
| Substance use | "Pt uses alcohol daily." | "10 to 12 standard drinks daily, mostly vodka, for 8 months. Last drink 06:30 today. Past withdrawal: tremor, sweats, one seizure in 2024. No injection use." |
| Risk | "Denies SI/HI." | "C-SSRS screen positive for passive ideation in the past month, no plan, intent or behavior. Protective factors: daughter, job. Overall risk low. Safety plan completed." |
| Housing | "Lives with friend." | "On a friend's couch for 3 weeks. Friend drinks nightly and keeps alcohol at home. Can stay 30 more days, no other option identified." |
| Strengths | "Motivated." | "Same employer 6 years. Wants to keep weekend custody of daughter. Stayed sober 14 months after IOP in 2022." |
| Mental status | "MSE WNL." | "Alert, oriented x4, mild agitation, normal speech, mood 'shaky,' affect anxious, thought process linear, no hallucinations, insight fair." |
| Diagnostic impression | "AUD." | "Alcohol use disorder, severe, 7 of 11 criteria: tolerance, withdrawal, drinking more than intended, failed attempts to cut down, craving, missed work, use despite family conflict." |
| Recommendation | "Recommend IOP." | "Withdrawal management with medical monitoring for Dimension 1 risk, then reassess. Outpatient withdrawal not safe: no sober support at home (Dimension 5)." |
The strong versions aren't longer for show. Each one hands a reviewer a fact to check against a criterion. I'd rather read a short assessment full of numbers and dates than a long one full of "denies" and "WNL."

Reassessment and updates
An assessment is a snapshot, and the rules expect it refreshed:
- Florida: an annual update after a year of continuous treatment, an update on readmission within 180 days if clinically indicated, and a new assessment after 180 days (65D-30.0042).
- Minnesota: a new or updated mental health diagnostic assessment when the client's condition changes markedly or the client asks, with outdated information removed (245I.10), and SUD plan reviews every 14 days in high-intensity residential and partial hospitalization, every 30 days in most other settings (245G.06).
- Opioid treatment programs: periodic reassessment, with care plan updates as treatment response and life circumstances change (42 CFR 8.12).
- CCBHCs: treatment plan review at least every 6 months (2.b.2).
Treat those as floors. Reassess at any change in level of care, a return to use or overdose, a new legal event, lost housing, a positive risk screen, a hospital stay or a readmission. Payers also expect new information at each continued-stay review, not admission text pasted forward.
42 CFR Part 2: handling SUD information in the assessment
At a Part 2 program, the assessment is a Part 2 record (42 CFR 2.11). The 2024 final rule's compliance date, February 16, 2026, has passed, so as of November 2026 these points apply:
- One consent can cover TPO. A single consent can cover all future treatment, payment and health care operations uses (42 CFR 2.33). Covered entities and business associates that receive records this way may redisclose them as HIPAA allows, except in proceedings against the patient, and don't have to segregate them.
- The notice travels with the record. Each disclosure made with consent carries the required notice (42 CFR 2.32).
- The assessment isn't a counseling note. SUD counseling notes, which need separate consent, exclude summaries of diagnosis, functional status, the plan, symptoms, prognosis and progress (2.11), as HIPAA psychotherapy notes do (45 CFR 164.501). Keep assessment content in the main record.
- Collateral calls are disclosures. Calling family or a probation officer for history usually reveals that the person is a patient. Get written consent first.
For the rest of the rule, see our 42 CFR Part 2 guide for 2026.
Common audit findings, and how to prevent them
Most assessment findings fall into a few patterns. Each breaks a specific rule, which makes it fixable.
| Finding | Why it fails | Prevention |
|---|---|---|
| Blank or "N/A" domains | State and CCBHC rules list required content. A blank reads as not assessed. | Require an answer, or a reason, in every domain before signature |
| Copy-forward | CMS says the record must show "the differences and the needs of the patient for each visit or encounter." | Show prior history as reference only, and make the clinician confirm each section |
| No validated suicide screen | NPSG.15.01.01 requires the screen, an assessment if positive, and a documented risk level and plan | Make the screen a required field |
| No link to the plan | The plan must be based on the assessment (Minn. Stat. 245G.06, CCBHC 4.e.2) | Every plan problem names the finding behind it |
| Late or unsigned | Minnesota counts it complete only on a dated signature. Florida requires a qualified professional's countersignature within 10 days if someone else wrote it. | Track due dates daily by level of care |
| Level of care doesn't match ratings | Payer criteria tie the level to dimensional risk | Rating, then reason, then level |
Before anyone signs, run five checks:
- Every domain has an answer or a documented reason.
- Substance use shows amount, route, last use and withdrawal history.
- A validated suicide screen is present, with a risk level and plan.
- Each ASAM dimension has a rating and a reason that match the recommended level.
- The signer's credentials fit the state's scope rule, and any countersignature is dated.
How Adentris helps
Adentris reviews every active chart, not a sample, against payer and regulatory rules before claims go out, including ASAM level of care, medical necessity, 42 CFR Part 2 and treatment plan timing. Our Documentation co-pilot works inside your EMR through browser integration and drafts documentation, including notes and treatment plan updates, for clinician review and signature. Documentation Compliance then flags gaps such as blank domains while the patient is on census, citing the rule and drafting a correction for staff to approve.
It runs on top of any EHR, usually with no IT project on your side, and AI inference stays inside Microsoft Azure. Sobrius Health, a multi-location Virginia SUD provider at ASAM levels 2.5 and 3.5, was fully live in 60 days with more than 100 active patients under continuous review.

Frequently asked questions
What is a biopsychosocial assessment?
It's a structured intake evaluation of the biological, psychological and social factors behind a person's condition. In behavioral health and SUD programs it supports the diagnosis and the treatment plan, including the level-of-care recommendation, and sets the baseline for measuring progress.
What should be included in a biopsychosocial assessment?
Presenting problem, psychiatric history, substance use history with amount, frequency, route, last use and withdrawal history, medical history, medications, trauma, family and social history, legal status, education and employment, housing, cultural and spiritual factors, strengths and preferences, risk and safety with a validated suicide screen, mental status, diagnostic impression and recommendations. Your state may add items.
Who can complete a biopsychosocial assessment?
It depends on state law and program type. Minnesota's licensed SUD programs may use alcohol and drug counselors, trained mental health professionals or APRNs, or supervised clinical trainees. In Florida, a qualified professional must countersign within 10 calendar days if the author isn't one. The diagnosis must stay within a licensed clinician's scope.
How soon after admission must the assessment be completed?
There's no national rule. Minnesota gives licensed SUD programs 5 days, Florida sets 3 to 30 calendar days by level of care, opioid treatment programs have 14 calendar days, and CCBHCs have 60 calendar days for the full evaluation. Set your deadline to the strictest rule that applies, and before the first treatment plan is due.
How often should a biopsychosocial assessment be updated?
Whenever something significant changes, such as a level-of-care change or a return to use, and at every readmission. Some states add a calendar floor. Florida requires an annual update for people in continuous treatment longer than a year.
Is a biopsychosocial assessment the same as an ASAM assessment?
They overlap. An ASAM assessment rates risk in six dimensions to recommend a level of care, and the biopsychosocial assessment gathers the history those ratings rest on. Many SUD programs combine them, and Minnesota requires its SUD assessment to include a rating for each dimension and a recommended ASAM level.
