What Is Addiction Psychiatry?
Addiction psychiatry is a subspecialty of psychiatry that focuses on treating individuals with substance use disorders and behavioral addictions. Addiction psychiatrists commonly treat conditions such as:
- Opioid use disorder
- Alcohol use disorder
- Cocaine or stimulant addiction
- Prescription drug misuse
- Gambling disorder
- Co-occurring mental health disorders
Treatment often includes psychotherapy, medication management, detox supervision, relapse prevention counseling, and long-term behavioral therapy.
Because addiction treatment programs involve multiple types of services and care models, CPT codes are used to standardize billing and ensure insurance companies understand the services provided.
Common CPT Codes Used in Addiction Psychiatry
Addiction psychiatry services typically fall under the psychiatry CPT code range (90785–90899) as well as certain evaluation and management (E/M) codes. Below are the most commonly billed CPT codes in addiction psychiatry practices.
| CPT Code | Description | Typical Use |
|---|---|---|
| 90791 | Psychiatric diagnostic evaluation | Initial addiction assessment |
| 90792 | Psychiatric diagnostic evaluation with medical services | Evaluation with medication review |
| 90832 | Psychotherapy (30 minutes) | Brief counseling sessions |
| 90834 | Psychotherapy (45 minutes) | Standard therapy sessions |
| 90837 | Psychotherapy (60 minutes) | Extended addiction counseling |
| 90853 | Group psychotherapy | Group addiction recovery therapy |
| 90846 | Family therapy without patient | Family addiction counseling |
| 90847 | Family therapy with patient | Family recovery therapy |
These CPT codes help insurers determine the type of treatment, session duration, and level of medical involvement in addiction treatment services.
Psychiatric Diagnostic Evaluation CPT Codes for Addiction Treatment
The first step in addiction treatment usually involves a comprehensive psychiatric evaluation.
CPT Code 90791 – Psychiatric Diagnostic Evaluation
This code is used when a mental health professional conducts an initial assessment without medical services.
The evaluation typically includes:
- substance use history
- psychological assessment
- mental status examination
- risk assessment for relapse
- development of an addiction treatment plan
CPT Code 90792 – Psychiatric Diagnostic Evaluation With Medical Services
This code is used when the evaluation includes medical components. Services may include
- medication assessment
- prescription of addiction medications
- review of physical health conditions
- coordination with primary care providers
Psychotherapy CPT Codes for Addiction Treatment
Psychotherapy is a central component of addiction treatment and recovery programs. Psychotherapy CPT codes are time-based, meaning providers must document session duration.
| CPT Code | Session Duration | Typical Use |
|---|---|---|
| 90832 | 16–37 minutes | Brief therapy session |
| 90834 | 38–52 minutes | Standard counseling session |

- build peer support networks
- participate in structured recovery programs
Group therapy sessions are often used in outpatient rehabilitation programs, inpatient addiction treatment centers, and community recovery programs.
This code is used when both the patient and family members participate in the therapy session.
These sessions help improve communication between family members and ensure proper care for elderly patients.

CPT Code 90853 – Group Psychotherapy
Group therapy is one of the most commonly used treatment methods in addiction recovery programs. These sessions allow patients to:

- build peer support networks
- participate in structured recovery programs
Group therapy sessions are often used in outpatient rehabilitation programs, inpatient addiction treatment centers, and community recovery programs.
Family Therapy CPT Codes in Addiction Psychiatry
Addiction affects not only the patient but also family members. Family therapy is therefore an essential part of many recovery programs.
CPT Code 90846 – Family Therapy Without Patient Present
This code is used when therapists meet with family members or caregivers to discuss addiction recovery strategies. Examples include:
- family education about addiction
- counseling for family members affected by substance abuse
- guidance on supporting patient recovery
CPT Code 90847 – Family Therapy With Patient Present
This code is used when both the patient and family members participate in therapy sessions.
Family therapy helps address:
- relationship conflicts caused by addiction
- family dynamics that contribute to substance use
- relapse prevention strategies
Medication-Assisted Treatment (MAT) and Evaluation Services
Medication-assisted treatment is widely used in addiction psychiatry to help patients manage withdrawal symptoms and reduce relapse risks. Common medications used in MAT include:
- Buprenorphine
- Methadone
- Naltrexone
When psychiatrists provide medication management alongside therapy, they may bill evaluation and management (E/M) codes combined with psychotherapy codes.
Proper documentation must clearly show both the psychotherapy service and the medical management component.
Major Billing Challenges in Addiction Psychiatry
Addiction treatment programs face several unique billing challenges.
1. Complex Treatment Programs
Addiction treatment often involves multiple therapy sessions, group therapy, and medication management within a single treatment plan.
2. Insurance Authorization Requirements
Many insurance companies require prior authorization for addiction treatment services.
3. Documentation Requirements
Insurers require detailed documentation showing medical necessity for addiction treatment services.
4. Medication-Assisted Treatment Billing Rules
Billing for MAT services requires strict documentation and proper coding combinations.
5. Behavioral Health Compliance Regulations
Addiction treatment programs must comply with both healthcare billing regulations and substance abuse treatment confidentiality laws.
