Billing for Couples & Family Therapy: A Clinician’s Ethics‑Driven & Insurance‑Savvy Guide

Updated on: July 26, 2025

Couples and family therapy offers immense clinical value by addressing relational dynamics that affect individual well‑being. However, navigating insurance billing for these services can be confusing. This guide clarifies correct coding, key policies, documentation strategies, extended session billing, and ethical considerations to support billing accuracy, compliance, and clinical integrity.


Why Couples & Family Therapy Billing Matters

  • Clinical Justification: Insurance reimbursement requires demonstrating medical necessity. Therapeutic sessions involving couples or families must center on the identified patient’s treatment goals.
  • Avoiding Fraud: Misbilling—such as using individual therapy codes or billing multiple insurers for the same session—is considered fraudulent and may risk licensure.
  • Accurate Claims Speed Payments: Using the correct CPT codes and modifiers reduces claim denials and supports prompt reimbursement.
  • Professional Trust & Integrity: Accurate documentation fosters trust with payers and clients and supports ethical practice.

Key CPT Codes for Couples & Family Therapy

CPT Code 90847 – Family or Couples Therapy With Patient Present

  • Use this when at least one person in the couple or family is the identified patient receiving treatment, and they are present during the session.
  • Requires a minimum of 26 minutes in session. Though many insurers expect a 50-minute standard.
  • Focus on relational dynamics as they affect the identified patient’s clinical picture.

CPT Code 90846 – Family or Couples Therapy Without Patient Present

  • Use when the identified patient is not present, but family members are engaged to support the patient’s treatment plan.
  • Also requires at least 26 minutes of active therapeutic work.

Why Not Use 90832, 90834, or 90837 Codes?

  • These are individual therapy codes (30, 45, or 60 minutes respectively). They are only used when an occasional family member joins a session meant for the identified patient—not for formal couples or family therapy.

Choosing the Identified Patient (IP)

  • Select one individual in the couple or family to designate as the identified patient. This person’s name and diagnosis go on the insurance claim.
  • If both parties have diagnoses, typically choose the one with more severe symptoms or the primary policyholder.
  • List only the IP’s insurance policy; do not list or bill for the other adult partner or family members to the same session.

Verification of Benefits & Coverage

  • Before the first session, always verify whether the client’s insurance plan covers couples or family therapy and under what conditions.
  • Inquire specifically about coverage for CPT codes 90847 and 90846. Avoid phrasing like “couples therapy” which may be interpreted as elective or non‑medical by payers.
  • Confirm coverage for both office-based and telehealth sessions, and note any required modifiers or preauthorization rules.

Documentation Standards

To support claims and audits, documentation must include:

  • Name of the identified patient and relevant diagnosis only.
  • Session duration (minimum 26 min).
  • Names and relationship of session participants.
  • Clinical focus: how relational issues tie to the patient’s treatment goals.
  • Evidence of medical necessity: progress notes, goals, risk factors, or symptoms that require relational intervention.

Billing Extended Therapy Sessions

Sessions longer than ~50 minutes may require additional codes:

Add‑On Codes:

  • 99354: First add‑on for additional time beyond the base CPT code (beyond 53–89 minutes).
  • 99355: Subsequent 30-minute increments beyond add‑on thresholds, billed cumulatively.

CHART: Extended Session Billing

Session Duration CPT Base Code Add‑On Code(s)
26–52 min 90846 / 90847 None
53–89 min 90846 / 90847 None
90–124 min 90846 / 90847 + 99354
125–154 min 90846 / 90847 + 99354 + 99355
155+ min 90846 / 90847 Additional 99355 units
  • Always document time and clinical justification for extended duration.
  • Verify coverage for extended sessions beforehand to avoid denials or surprise out-of-pocket charges.

Common Mistakes & Pitfalls To Avoid

  • Using individual therapy codes for couples sessions (90832/90834/90837), which describe sessions primarily with one person—incorrect for relational treatment models.
  • Billing both insurance plans when both partners hold policies for the same session – this constitutes double billing and is fraudulent.
  • Incorrectly identifying the IP, listing all participants with diagnoses, or using unclear diagnosis language reduces compliance.
  • Skipping verbal or written warnings around policy non‑coverage for relationship‑focused work or elective therapy.

Clinical Workflow Tips

Step‑by‑Step Process:

  1. Verify coverage for 90847 or 90846 and confirm medical necessity requirements.
  2. Determine the identified patient—document selection criteria.
  3. Use 90847 if the IP is present; if not, use 90846.
  4. Document duration, participants, focus, and necessity clearly.
  5. For extended sessions, add CPT add‑on codes with documentation.
  6. Submit a single claim under the identified patient’s insurance.
  7. Do not bill separate insurers for the same session.

Template Recommendation:

In your electronic health record or practice management system, build templates to automatically:

  • Capture IP selection,
  • Choose correct CPT code,
  • Track timed sessions,
  • Itemize participants,
  • Map relational interventions to treatment goals.

Ethical and Professional Considerations

  • Do not misrepresent services: If most of the session concerns relationship-building or conflict resolution unrelated to an individual’s mental health diagnosis, properly assess whether insurance coverage is appropriate.
  • Transparent consent: Clients should be informed about billing practices, coverage limitations, and out-of-pocket possibilities.
  • Licensing boundaries: Only credentialed mental health professionals bill these codes, consistent with local licensure norms.
  • Clear recordkeeping: Maintain full documentation to support audit compliance and ethical accountability.

Why Proper Billing Matters Clinically

  • Ensures clients receive needed therapy without unexpected bills or denials.
  • Supports financial sustainability of relational therapy in private practice.
  • Demonstrates professional integrity to clients and payers.
  • Reduces administrative errors and claim rejections.
  • Aligns insurance billing with quality treatment documentation.

Summary of Key Billing Guidelines

  • Use CPT 90847: For couples/family therapy when the identified patient is present.
  • Use CPT 90846: For family therapy when the identified patient is absent.
  • Do not use individual therapy codes for relational sessions.
  • Select one Identified Patient: name and diagnosis listed on claim only.
  • Verify insurance coverage in advance and explain medical necessity.
  • Add-on codes for sessions longer than standard duration.
  • Bill only one insurance plan per shared session.
  • Document thoroughly: duration, participants, focus, treatment relevance.

Final Reflection: Supporting Ethical, Accurate, and Client‑Centered Practice

Couples and family therapy bring depth and healing for individuals within relational systems. When clinicians apply correct CPT codes, clear clinical rationale, and careful documentation, they uphold both ethical and financial integrity.

Clear claims = fewer denials.
Accurate notes = clearer treatment rationale.
Ethical billing = trust with clients and payers.

With structured workflows and professional diligence, billing can bolster—not hinder—the delivery of high-quality relational mental health services.
