Family Therapy Billing: When to Use 90846 vs 90847

Introduction

In behavioral health practices, treating an individual often requires engaging their family, spouse, or primary caregivers. Whether helping parents manage a child’s behavioral health condition or working with a spouse to support a patient recovering from severe trauma, family sessions are an essential clinical tool. However, when it comes to family therapy billing, clinicians and medical billing staff frequently run into confusion. Does the patient need to sit in the room for the entire visit? Which CPT code applies when speaking only with parents or guardians? How should claims be constructed when family members are involved?

Selecting between CPT 90846 and CPT 90847 requires a clear understanding of patient presence rules, proper claim setup around the “identified patient,” and strict documentation standards. Here is a practical guide to handling these codes cleanly and avoiding preventable denials.

The Core Distinction: CPT 90846 vs CPT 90847

Both codes describe family psychotherapy sessions aimed at addressing interactions, communication patterns, and environmental factors that affect a patient’s emotional or behavioral health. The fundamental difference between the two codes comes down to one factor: whether the identified patient is physically or virtually present during the encounter.

• CPT 90846 (Family psychotherapy without patient present): Used when the therapist meets exclusively with family members, legal guardians, or caregivers to discuss the patient’s treatment plan, coping strategies, or behavioral management without the patient in the room.
• CPT 90847 (Family psychotherapy with patient present): Used when the identified patient participates in the family therapy session alongside one or more family members or significant others.

Who Is the “Identified Patient”?

In family therapy billing, claims are never billed under a family member’s name simply because they attended the appointment. All services are billed under the Identified Patient (IP)—the individual who has been evaluated, diagnosed, and established on a psychiatric treatment plan.

Even when billing family psychotherapy without patient present under code 90846, the claim must be submitted using the identified patient’s demographic information, member ID, and primary ICD-10 diagnosis code. The service must directly serve the treatment needs of the patient, even if they do not sit in the room during that specific appointment.

Key Scenarios: Knowing Which Code to Bill

To help clarify real-world application, consider how different clinical setups dictate code selection:

Scenario A: Parent-Only Consultation for a Minor

A clinician meets with the parents of a 10-year-old child diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD). The purpose of the 50-minute session is to train the parents on behavioral reinforcement techniques to use at home. The child stays in the waiting room and does not participate in the session.

• Correct Code: CPT 90846 (billed under the child’s insurance and NPI record).

Scenario B: Combined Family Session

A therapist conducts a 50-minute session involving a adolescent patient diagnosed with major depression and both parents to resolve family conflicts impacting the patient’s emotional stability. All three participants sit in the room for the entire hour.

• Correct Code: CPT 90847 (billed under the adolescent’s insurance).

Scenario C: Split-Session Encounters

A therapist meets with a adult patient suffering from severe anxiety for 15 minutes, and then brings the patient’s spouse into the office for another 35 minutes to conduct a joint family intervention addressing marital stressors affecting the anxiety.

• Correct Code: CPT 90847. Because the identified patient participated in a portion of the family therapy encounter, the overall session qualifies as family therapy with the patient present.

Important Note: You cannot bill both 90846 and 90847 on the same date of service for the same patient by the same rendering provider. Select the single code that best represents the overall encounter structure.

Documentation Essentials for 90846 and 90847

Payer audits of family therapy claims often focus on two areas: proving medical necessity for the identified patient and verifying who attended the session.

To satisfy 90847 documentation requirements and avoid recoupments on 90846 claims, progress notes should clearly contain:

1. Clear Identification of Participants

Explicitly list who attended the appointment by name and relation (e.g., “Jane Doe [Mother], John Doe [Father]”). For 90846 notes, state clearly that the identified patient was not present during the session.

2. Direct Tie to the Patient’s Treatment Plan

The note must explain how conducting family therapy directly addresses the identified patient’s illness or recovery. For example, when documenting 90846, record how educating the family members supports the patient’s target symptoms, risk management, or skill development.

3. Therapeutic Focus and Techniques

Document the specific family therapy techniques utilized during the session (e.g., structural family therapy, communication skills training, conflict resolution strategies) rather than framing the note as a generic “status update” or routine progress discussion.

4. Total Session Time

Both 90846 and 90847 are typically defined as 50-minute services in CPT guidelines. Record start and stop times or total session duration in the clinical record to substantiate that adequate therapeutic time was provided.

Payer Coverage Rules and Potential Pitfalls

While CPT guidelines establish clear definitions for CPT 90846 vs 90847, commercial insurers, Medicare, and state Medicaid programs may apply specific payment policies that impact reimbursement.

1. Payer Non-Coverage for 90846

While Medicare and most commercial health plans cover 90846 when medically necessary, certain state Medicaid plans or narrow commercial networks exclude coverage for family therapy when the patient is absent. Always check eligibility and benefit details before rendering services under 90846 to determine if patient presence is a mandatory condition of payment for that specific payer.

2. Unbundling with Individual Psychotherapy (CPT 90834 / 90837)

Clinicians occasionally attempt to bill an individual therapy session (e.g., 90834) and a family therapy session (90846 or 90847) on the exact same day. Payers almost universally view this as unbundling unless the sessions were conducted at completely separate times for distinct clinical reasons. If submitting both on the same date, separate documentation and proper national correct coding initiative (NCCI) modifiers (such as Modifier 59 or XE) are generally required.

3. Group Therapy Misconceptions

Family therapy codes (90846/90847) are designed for the family unit or primary caregivers of a single identified patient. They should never be used when treating multiple unrelated patients or multiple families simultaneously in a group setting; those sessions must be reported using multi-family group therapy (CPT 90849) or standard group therapy (CPT 90853).

Practical Checklist: What to Do and What NOT to Do

What TO Do

• Bill Under the Identified Patient: Always list the patient receiving care as the subscriber/patient on the claim, regardless of who attends the session.
• Document Specific Caregiver Goals: For 90846 claims, document how guiding the family directly benefits the patient’s psychiatric management plan.
• Verify Telehealth Guidelines: If family therapy is provided virtually, verify whether the payer requires modifier 95, GT, or FQ, and confirm that all remote participants are located in approved regions.

What NOT To Do

• Do Not Bill Under the Parent or Spouse: Never submit a claim under a family member’s insurance if they are not the established, evaluated patient.
• Do Not Bill 90846 as Case Management: Code 90846 is reserved for formal family psychotherapy. Do not use 90846 to report brief phone calls, administrative coordination, or interdisciplinary care conferences.
• Do Not Double-Bill Sessions: Never report 90846 and 90847 together for the same session encounter.

Summary

• Base Code Selection on Patient Presence: Use CPT 90847 when the identified patient is present for all or part of the family session. Use CPT 90846 when the session is conducted solely with family or caregivers.
• Always Bill the Identified Patient: Regardless of attendance, the claim must be filed under the record, diagnosis, and policy of the primary patient being treated.
• Document Clinical Benefit: Progress notes for 90846 must explicitly state why meeting without the patient was medically necessary and how it advances the patient’s treatment goals.
• Verify Payer Policy: Confirm whether the patient’s specific insurance policy covers 90846 without restrictions prior to rendering services.
