Clinicians usually log a drug addiction diagnosis as a substance use disorder linked to one drug. They decide this by checking your symptoms against set rules for that substance. One screening, drug test, or self-check cannot prove the diagnosis alone.
This guide outlines the criteria clinicians use. It explains how severity levels work and what an evaluation involves. You will learn how diagnosis names and codes appear in medical records.

Understanding Substance-Related Diagnoses
You may hear the term drug addiction diagnosis in everyday talk. Clinics officially call it a substance use disorder linked to one drug. A clinician might diagnose opioid use disorder, for instance.[1]
Everyday words and medical terms can feel very different. You might hear someone say a person is addicted to opioids.
Medical names for these issues have changed over the years. Past guides used separate labels such as “dependence” and “abuse.” The DSM-5 combined those two labels into one diagnosis.[2] This single diagnosis grades the problem’s severity from mild to severe.[2]
This guide describes how these diagnoses work. It cannot say if you or a loved one has one. A licensed clinician must make that decision after an evaluation. To see how these rules apply to alcohol, read about the DSM-5 criteria for alcohol use disorder.
The 11 Criteria for Diagnosing Substance Use Disorder
Clinicians use the DSM-5-TR manual. It lists 11 criteria for substance use disorder. A diagnosis requires at least two of these criteria to occur within a 12-month period.[3] Clinicians assess the whole picture. Counting boxes on a webpage is not a diagnosis.
11
criteria in the DSM-5-TR for substance use disorder[3]
2+
criteria within 12 months needed for a diagnosis[3]
2–3 / 4–5 / 6+
criteria for mild, moderate, or severe severity[4]
| Criterion | What it looks like |
|---|---|
| Tolerance | Taking far more of the drug to feel the same effect. |
If you take prescribed medication exactly as directed under proper medical supervision, tolerance and withdrawal do not count toward a diagnosis.[5] This rule helps clarify the difference between physical dependence and addiction.
Drug Tests and Screening Do Not Diagnose
You may ask if a lab test or quick survey can diagnose you. Such tools help, yet they cannot take the place of a full check-up.
Screening questions highlight possible concerns. They can help you decide whether to speak with a professional about your substance use. Yet they cannot diagnose a condition on their own. If you get a high score, you should seek an evaluation. That does not mean you definitely have a disorder.
Toxicology tests show exposure to substances during a detection window. This window changes based on the substance and test type. These tests can find a substance or its byproducts in a sample. But they do not show if someone is currently impaired. They also do not prove someone meets the criteria for a disorder. They do not show if you meet the diagnostic criteria for a substance use disorder. A negative result does not prove substance use never happened. It also does not rule out a substance use disorder, which is a clinical diagnosis.[6] Some initial screening results can be false positives. They may need confirmatory testing.[7]
Use online drug use self tests to help get ready for a talk with your doctor. These tools are designed to start a discussion, not to give answers. A proper diagnosis requires a qualified clinician to review your history and symptoms.
During the Diagnostic Evaluation
Figuring out how substance use disorder is diagnosed can feel intimidating. Actually, the evaluation is mainly just a talk. A clinician will ask about your use patterns, control, noticed consequences, and how it impacts daily life. They may also ask about your physical and mental health, other substances you use, and your social situation. A provider may examine you and ask about your medical and family history.[8] Depending on your symptoms and health history, a provider may examine you or order tests to check for health problems.
Visits do not always follow one order. Here is a good way to prepare.
- Describe your use. Describe what you take, how often, and changes over time.
- Talk about the effects. Share how use has affected your health, work, school or relationships.
- Share your history. List medical conditions, mental health issues, or past care.
- Ask questions. Have the clinician explain findings and what may happen next.
You can always ask what details are being weighed and how the clinician formed their conclusion. For a complete overview of this process, read more about what happens during an addiction evaluation.
What Severity Labels Mean and Do Not Mean
During a drug addiction diagnosis, a clinician may assign a severity level. The DSM-5-TR uses mild, moderate, and severe. These labels depend on how many criteria you meet.
These labels show how many criteria you met. They do not show how strong each symptom is. They are not a judgment of your character. They do not measure how hard you are trying.
A severity label is not a plan for your treatment. Health care professionals use DSM-5 criteria to check for a substance use disorder. If the disorder is present, they use these criteria to set the severity.[4]
A "severe" label does not automatically mean you need inpatient care. If the label is mild, it does not mean you lack a need for support.
| What the severity label describes | What the severity label does not establish |
|---|---|
| The number of diagnostic criteria met | The specific treatment setting needed |
| A snapshot of symptom count | Every one of your support needs |
Counting symptoms is not all clinicians do. The ASAM Criteria tells treatment professionals to use a multidimensional assessment.[9] This process reviews biomedical, psychological, and social factors. These factors affect what your recovery needs.[9]
Your situation may change as time passes. A clinician can review your care needs again as your life changes. This keeps support matched to where you are now. It avoids relying only on an initial substance use disorder severity label.
DSM-5 Name for Drug Addiction
The DSM-5-TR does not have a single label for addiction. It uses substance use disorders based on the specific drug. For example, alcohol use disorder is the official term for alcohol issues. This clinical term means an impaired ability to stop or control drinking, even with negative consequences.[4]
Older or informal words like "substance abuse" or "dependence" may still appear in conversations. But these are not the current diagnostic labels. DSM-5 combined substance abuse and dependence into one substance use disorder diagnosis, rated from mild to severe.[2]
Medical records may show codes too. These codes differ from the DSM name.
Because codes change over time, it is best not to rely on a fixed list of DSM codes for substance use disorder found online.
What your clinician documents determines the right code. Ask your clinician or the billing office to check a code in your chart if you have questions.
Reviewing the Diagnosis and Picking Your Next Move
A diagnosis is just a starting place, not a final ruling. It explains what you face but does not force one path. Substance use disorders can be treated, and recovery is possible.[10]
Ask the clinician which criteria backed the diagnosis. Ask how the severity label affects you. If your records have a code, ask for details. This clarifies what was recorded.
Treatment choices vary a lot. A qualified professional can help match your needs to the right setting. Read about choosing the right level of care to see how intensity is chosen.

Frequently Asked Questions
What is the medical diagnosis for addiction?
What are the four indicators of substance abuse disorder?
The DSM criteria fall into four groups: impaired control, social impairment, risky use, and pharmacological criteria.[12] These groups sort the symptoms. These are not four distinct tests. Clinicians review the full picture to reach a diagnosis.
Does a drug test diagnose addiction?
No, it cannot. A drug test shows recent substances in the body. It does not confirm a substance use disorder.[6] Only a clinical check tells if criteria are met. Routine panels may miss some drugs, so ask your clinician what a result covers.
Who can diagnose a substance use disorder?
A qualified healthcare or behavioral health professional can check your substance use. They can make a diagnosis within their scope of practice. State laws define which professionals may diagnose mental health conditions.[13] Ask about credentials and substance-use experience if you doubt a provider's qualifications.
What are the DSM codes for substance abuse?
There is no single code for substance abuse. The DSM-5 combined substance abuse and dependence into one diagnosis. This is called substance use disorder. It ranges from mild to severe.[2] Clinicians find the right code by identifying the substance. They also check severity based on criteria met: mild (two to three), moderate (four to five), or severe (six or more).[4] Ask your clinician or billing office to confirm the exact code on your paperwork.
