How Your Level of Care Is Decided in San Diego: The Six ASAM Dimensions Explained

When you call a treatment program, one of the first things you want to know is simple: do I need detox, residential care, a day program, or something I can fit around work? The answer is not a guess, and it is not a sales decision. At most licensed programs in California, including here in San Diego, the recommendation comes from a structured assessment built on The ASAM Criteria, the placement framework published by the American Society of Addiction Medicine. This guide walks through how that assessment works, what each of its six dimensions asks about, and how the result turns into a specific level of care.

The Short Answer: Six Dimensions, One Placement

The ASAM Criteria place a person in addiction treatment by assessing six dimensions of their situation, not just which substance they use or how much. A clinician rates risk in each dimension, and the combination of those ratings points to the least intensive level of care that can still treat the person safely and effectively, from outpatient counseling up to medically managed inpatient care. Because the ratings are reassessed during treatment, the level of care is expected to change as the person’s needs change, and a placement made on day one is not a fixed sentence.

The American Society of Addiction Medicine describes the framework and its fourth edition, released in 2023, on its ASAM Criteria overview page. California’s Medi-Cal substance use system and many commercial health plans rely on the same framework when they review whether a level of care is medically necessary.

What the Six Dimensions Ask About

Each dimension is a set of questions a clinician works through with you. In plain terms, here is what they cover:

• Intoxication, withdrawal and addiction medications: whether you are currently intoxicated, how likely withdrawal is to be dangerous, and whether medications such as buprenorphine or naltrexone are part of the picture.
• Biomedical conditions: physical health problems that could complicate withdrawal or treatment, such as heart, liver or seizure history, pregnancy, or chronic pain.
• Psychiatric and cognitive conditions: co-occurring depression, anxiety, trauma, bipolar disorder, or cognitive limitations that change how treatment needs to be delivered.
• Substance use-related risks: how likely continued use is right now, and what has happened after previous attempts to cut back or stop.
• Recovery environment interactions: where you will sleep tonight, who lives there, whether substances are in the home, and whether work, family or legal pressures will help or undermine recovery.
• Person-centered considerations: your own goals, preferences, cultural needs, and practical barriers such as transportation, childcare or a job you cannot leave.

No single dimension decides the outcome. Someone with mild withdrawal risk but no safe place to live may need a residential setting. Someone with heavy daily use but a stable home, no withdrawal danger and strong support may do well in a structured outpatient program.

How the Ratings Become a Level of Care

ASAM levels are numbered, and you will often see those numbers on insurance paperwork. In general terms, the continuum runs from Level 1 (outpatient), through Level 2 (intensive outpatient and partial hospitalization, also called day treatment), Level 3 (residential), and Level 4 (medically managed inpatient care, typically hospital-based). Withdrawal management, or detox, is matched to its own intensity based on the first dimension. The fourth edition revised some level names and descriptions, so the exact labels on a form may differ slightly depending on which edition a program or payer is using.

In San Diego, that usually translates into a few practical paths:

• Medically supervised detox when withdrawal itself carries risk. Alcohol and benzodiazepine withdrawal can cause seizures and, in severe cases, become life-threatening, so stopping either after heavy or long-term use may require medically supervised detox rather than quitting at home. Our San Diego detox program explains what that stay involves.
• Residential treatment when the risk of returning to use, the home environment, or co-occurring conditions mean you need 24-hour structure. See how our residential treatment in San Diego is organized day to day.
• Partial hospitalization or intensive outpatient when you can live at home or in sober living safely but still need several hours of treatment most days. Our partial hospitalization program is one example of that middle step.

The Rule California Health Plans Have to Follow

Here is a detail many families never hear about. California’s Senate Bill 855, which took effect January 1, 2021, requires state-regulated health plans and insurers to base medical necessity decisions for mental health and substance use disorders on generally accepted standards of care, and to use criteria developed by the relevant nonprofit professional associations. For substance use treatment, that generally means The ASAM Criteria. In practice, this matters most when a plan approves fewer days than the clinical team recommended, or approves outpatient care when the assessment pointed to residential. If the clinical record documents the six-dimension ratings clearly, there is a concrete standard to appeal against.

Not every plan falls under SB 855. Self-funded employer plans regulated under federal law, and some government programs, follow different rules. Ask the admissions team which rules apply to your coverage before you assume an appeal will work the same way.

What Assessment Day Actually Looks Like

The assessment is a conversation, not a test you can fail. Most people start with a shorter phone screening that covers recent use, withdrawal history, medications, health conditions and insurance. If a higher level of care looks likely, the full assessment happens at admission and usually includes a nursing or medical evaluation, vital signs, a urine drug screen, and a longer interview with a clinician who works through each dimension.

Expect questions that feel personal: when you last used and how much, whether you have ever had a seizure or blackout during withdrawal, whether anyone at home uses, whether you have thoughts of harming yourself, and what you want out of treatment. Honest answers are what make the placement accurate. Underreporting daily alcohol use or benzodiazepine doses can lead to a placement that is not safe enough. Overstating to secure a higher level of care tends to show up quickly once medical monitoring begins.

Your information is protected. Federal confidentiality rules for substance use treatment records are stricter than for most other health records, and the team should explain who can and cannot see your assessment before you sign anything.

What to Do Before You Call

You can make the assessment faster and more accurate with a few minutes of preparation today. Write down the following on one sheet of paper or in your phone notes:

1. Every substance used in the past 30 days, roughly how much per day, and the date and time of last use.
2. Any past withdrawal symptoms, especially seizures, hallucinations, or confusion.
3. All current prescriptions with doses, including anything prescribed for sleep, anxiety, pain or ADHD.
4. Major health conditions and any mental health diagnoses.
5. Where you would live during treatment, and whether anyone there drinks or uses.
6. Your insurance card, front and back, and the name of the policyholder.

Then ask one specific question on the call: “Which ASAM level are you recommending, and which dimensions drove that recommendation?” A program that has done a real assessment should be able to answer in plain language.

Placement Changes as You Do

Level of care is meant to be reviewed throughout treatment. As withdrawal resolves, sleep improves and skills build, the dimension ratings usually drop, and the team plans a step-down to a less intensive setting. The reverse can happen too: a return to use or a mental health crisis during outpatient care can raise the ratings and point back toward more support. The National Institute on Drug Abuse’s principles of effective treatment make the same point: treatment plans should be assessed continually and modified to fit a person’s changing needs.

Do not stop alcohol, benzodiazepines or other prescribed medications abruptly without speaking to a qualified medical provider, because withdrawal from some substances can be dangerous.
