Family Therapy Billing: How to Get Paid for 90847 and 90846 Without the Headaches

Why Family Therapy Billing Has Its Own Rules

The foundation of family therapy billing depends on the identified patient concept. Insurance covers therapy when it treats a diagnosed mental health condition belonging to one specific person. For family or couples sessions, that individual must have a qualifying DSM diagnosis, and the session supports their treatment plan rather than general relationship maintenance.

Insurance isn't paying for the family to be in the room — it's paying to treat the identified patient, and their presence becomes part of the clinical method. Couples therapy focused solely on communication skills without a documented mental health diagnosis typically faces denial.¹ Practices must designate an identified patient before the first session to avoid retroactive denials during audits. Understanding this distinction is part of the broader complexity covered in insurance billing for mental health.

CPT Code 90847 vs. 90846: The Decision Point

The choice between codes hinges on one factor: Is the identified patient present?

• CPT 90847 (Family psychotherapy with patient present): Used when the identified patient attends. Sessions require minimum 26 minutes, though many payers expect 50 minutes.²

• CPT 90846 (Family psychotherapy without patient present): Used for family-only meetings when the identified patient is absent. Same time requirements apply.

Only one code applies per date of service. The most frequent error involves billing 90847 habitually even when the identified patient didn't attend, creating audit exposure during documentation reviews. This type of coding error is one of the leading contributors to claim denials in behavioral health.

Documentation Requirements

Claims must list only the identified patient's name, diagnosis, and insurance information. Progress notes require three elements:

1. Attendance details (names and relationships)
2. Session duration in minutes
3. Treatment plan connection explaining how the session addresses the identified patient's diagnosis and goals

Vague documentation fails. Notes must explicitly link family sessions to the patient's condition. For 90846 sessions, document why the patient was absent and how the meeting advances their treatment objectives. Just as with individual therapy session codes like 90834 and 90837, the documentation standard is specific: what was done, who was present, and for how long.

Pre-Session Coverage Verification

Most family therapy billing problems are preventable through early verification. This step is a core part of revenue cycle management for practices that see family or couples cases regularly:

• Confirm whether CPT codes 90847 and 90846 are covered separately
• Verify prior authorization requirements
• Identify cost-sharing structures specific to family sessions
• Discuss self-pay arrangements before the first appointment

Documentation of verification becomes crucial for appeals. Scheduling verification catches coverage exclusions before therapeutic relationships develop. When clients ask about their out-of-pocket responsibility, explaining copays and deductibles clearly during this stage prevents confusion later.

Common Denial Reasons and Responses

Family therapy claims typically fail for five reasons:

• Coverage exclusion: Plan excludes family therapy entirely
• Missing diagnosis: No DSM diagnosis appears on the claim
• Insufficient medical necessity: Diagnosis present but not clinically justified in notes
• Timely filing deadline: Claims submitted beyond the allowed window — timely filing denials can be avoided with consistent submission workflows
• Inadequate documentation: Notes fail to support the service rationale

Reimbursement rates for both codes typically range from $85 to $200 per session depending on payer and location,³ often lower than comparable individual therapy sessions. If your rates feel low, understanding your payer contracts and fee schedules can reveal whether renegotiation is warranted.

If your practice bills family therapy codes regularly and is seeing elevated denials, behavioral health billing services designed specifically for outpatient and specialty practice can reduce the administrative burden and protect your revenue.
