What Is Multiple Family Therapy? A Guide for Mental Health Providers

Mental health professionals are constantly adapting their care models to better serve patients and families. One increasingly recognized approach is multiple family therapy—a method that brings together several families facing similar challenges to foster shared healing, understanding, and progress. For behavioral health organizations and private practices, understanding how to integrate this approach both clinically and operationally—especially in terms of billing—is essential.

What Is Multiple Family Therapy?

Multiple family therapy (MFT) involves two or more families participating in therapy sessions together, guided by one or more clinicians. This structured, therapeutic format creates a supportive environment where families can gain insight from one another, share coping strategies, and receive professional guidance on managing behavioral or mental health conditions.

MFT is commonly used for conditions such as substance use disorders, adolescent behavioral issues, eating disorders, and chronic psychiatric illnesses. Unlike traditional single-family sessions, MFT creates a community dynamic that can reduce stigma, promote empathy, and offer broader social support.

Understanding CPT Code 90849 for Multiple Family Therapy Sessions

Correctly billing for these sessions is just as important as providing them. That’s where CPT Code 90849 comes in. This code is specifically designated for multiple-family group psychotherapy sessions that do not include the patient. Clinicians use 90849 to report services that focus on family members’ interactions, education, and problem-solving, with the goal of supporting the identified patient’s treatment plan.

This is distinct from other family therapy codes, such as 90846 and 90847, which are used for single-family therapy—with or without the patient present. Providers should always consult updated payer guidelines, as requirements and reimbursement policies can vary between insurers.

When to Use Multiple Family Therapy and How It Supports Behavioral Health Treatment

MFT is most beneficial in cases where shared experiences across families can accelerate recovery and reduce isolation. For example, families of adolescents in residential treatment for substance use may benefit from exploring communication challenges and boundary-setting in a group context.

In a clinical setting, multiple family therapy is particularly effective when:

• Families are dealing with similar conditions or diagnoses

• Peer support can enhance engagement and accountability

• Emotional burnout among caregivers is high

• There’s a need to reframe family dynamics through real-time observation

MFT enhances care plans by extending therapeutic interventions beyond the individual, building a stronger recovery network and improving treatment adherence.

Key Documentation Requirements for Billing Multiple Family Therapy Services

Proper documentation plays a critical role in both compliance and reimbursement. When billing with CPT 90849, clinicians should include:

• Session date and duration

• Number of families involved

• Primary therapeutic goals

• Techniques used (e.g., psychoeducation, systems-based interventions)

• Progress made toward objectives

• A clear clinical rationale for using the multiple-family model

Also, it’s helpful to document how the family members’ participation supports the treatment plan of the identified patient. Detailed records not only help secure reimbursement but also improve continuity of care.

Multiple Family Therapy vs. Single Family Sessions: Billing and Clinical Differences

While both therapeutic approaches aim to support the patient’s wellbeing, they are distinct in purpose and billing. Single-family sessions (90846 or 90847) offer a more individualized approach, focusing exclusively on one family unit’s dynamics. They’re useful for high-conflict scenarios or when specific relational issues need concentrated attention.

On the other hand, multiple family therapy adds value when common themes across families—such as substance use, chronic illness, or emotional trauma—are better addressed through group insight and collective discussion.

Billing codes reflect this distinction, so mental health providers should evaluate their service delivery model and choose codes based on the session structure and participants involved.
