Comprehensive Guide to CPT 90847: Billing, Coding, and Reimbursement for Family Therapy (2026)

Schedule Your Free Consultation

Family therapy billing gets messier than most providers expect. The clinical work isn't complicated figuring out which code applies, what documentation needs to say, and why a clean claim keeps coming back denied is where practices lose money.

CPT 90847 is one of those codes where the concept is simple but execution is where things fall apart. Patient present? That's your code. Patient not there? Different code entirely. But somewhere between that simple rule and actual claim submission, practices lose track and that confusion costs real money. This guide covers CPT 90847 billing the way it actually works: what the code requires, how it differs from 90846, what your documentation needs to say, where billing errors show up, and what to do about it.

What Is CPT 90847?

CPT 90847 is the billing code for family psychotherapy with the patient present. That phrase 'with patient present' is the whole thing. It means you're delivering family therapy as part of a treatment plan for a specific identified patient, that patient is physically in the room (or on the synchronous telehealth session), and the therapeutic work involves the patient's family members as part of that treatment.

This isn't a consultation or family education code. It's active psychotherapy for an identified patient, delivered in a family context. A therapist working with a teenager and parents on communication patterns contributing to depression. A psychiatrist meeting with a patient and spouse to address relationship dynamics affecting treatment. A child patient and caregivers in a session tied to an ABA-informed treatment model. Those are 90847 sessions.

Who can bill it: psychiatrists, psychologists, LCSWs, LPCs, LMFTs any licensed provider whose scope of practice includes family psychotherapy in their state.

CPT 90847 vs CPT 90846: One Difference That Changes Everything

These two codes are a constant source of claim errors, and the confusion is understandable because the services look similar on the surface. Both are family therapy codes. Both involve family members. One small distinction separates them and billing the wrong one means an automatic denial or a compliance problem.

The practical rule: document who was in the room. Patient listed as a participant: 90847. Family members only, patient absent: 90846. Where practices get into trouble is inconsistent documentation a note referencing the patient's treatment goals without stating they were present, or a 90847 written for what was actually a parent-only call.

What CPT 90847 Doesn't Have — and Why That Matters

Unlike individual psychotherapy codes, CPT 90847 has no defined time threshold. The AMA defines it as a service, not a timed unit no '16-minute minimum' equivalent. That said, payers absolutely review clinical reasonableness. An 8-minute family therapy note gets scrutinized. A note documenting a substantive session with defined interventions and patient response is defensible at 30 or 60 minutes. No formal time requirement means more flexibility, not less documentation attention.

Documentation Requirements for CPT 90847

Family therapy documentation that's vague, doesn't confirm patient presence, or fails to establish medical necessity is the most common reason well-conducted sessions don't get paid. Here's what every CPT 90847 note needs:

The note that fails an audit mentions the session happened and documents some content without ever stating who was in the room. 'Met with the family regarding communication patterns' doesn't confirm patient presence. 'Met with patient John and his parents to address communication dynamics related to John's treatment goals' does. Small habit, significant compliance difference.

Common CPT 90847 Billing Mistakes

•       Billing 90847 when the patient wasn't in the session. Parent check-ins and caregiver meetings without the identified patient are 90846. Note templates that auto-populate can create this error without the clinician noticing.

•       Documentation that doesn't confirm patient presence explicitly. Notes referencing the patient's treatment goals without stating they were present create ambiguity that payers resolve with a denial.

•       Billing 90847 alongside individual psychotherapy on the same date. Some payers allow it when the services are clearly distinct; others don't. Check payer policy before assuming. Same provider, same session, same patient = one service, not two.

•       Wrong diagnosis code. Family therapy needs the identified patient's diagnosis not a family/relationship code the payer doesn't recognize as billable for this service type.

•       Skipping payer-specific authorization. Several payers require prior auth for family therapy separately from individual therapy. A well-documented claim without the authorization number denies regardless of clinical quality.

•       Copy-pasting notes across sessions. Identical notes over months raise audit flags even when sessions were genuinely different. Each note should reflect what actually happened that day.

CPT 90847 Reimbursement — What to Expect

CPT 90847 reimbursement varies by payer, geography, and contracted rate. From working with behavioral health practices regularly: the rate is generally comparable to or slightly above 90834 in most markets, and typically above 90846.

Payer scrutiny on family therapy codes has increased not because the code is problematic, but because behavioral health generally receives more medical necessity review. Payers want family therapy tied to an active treatment plan with a supporting diagnosis and documented ongoing clinical justification.

The practices collecting best on 90847 aren't the ones with the highest contracted rates. They're the ones with the highest clean claim rates patient presence confirmed, diagnosis appropriate, authorization current. Clean claims get paid. Incomplete ones sit in AR and don't get appealed because nobody has time.

What Gets a CPT 90847 Claim Denied

•       Missing or ambiguous patient presence documentation. If the note doesn't clearly confirm the patient was present, payers default to 90846 or denial.

•       Medical necessity not established. 'Family met to discuss communication' without a clinical frame tied to the patient's diagnosis fails medical necessity review.

•       Expired or missing prior authorization. Family therapy auth is often a separate category from individual therapy an active individual auth doesn't automatically cover family sessions.

•       Diagnosis code mismatch. Using a Z-code for family relationship problems as primary diagnosis when the payer expects the identified patient's mental health diagnosis generates denial.

•       Frequency outliers. Some payers flag 90847 when it's billed too frequently without corresponding individual therapy sessions in the record. Not an automatic denial, but it can trigger a records request.

A Real-World CPT 90847 Billing Scenario

The Session

An LCSW treating a 15-year-old with MDD schedules biweekly family sessions alongside individual therapy. In this session: patient and both parents, 50 minutes, working on communication patterns and coaching parents on responding to the patient's depressive symptoms. The patient is directly involved throughout.

How to Document It

The note names all participants: patient, mother, father. Identifies the session as family psychotherapy within the treatment plan. States the clinical focus explicitly communication dynamics and parental support behaviors related to MDD. Documents specific interventions, patient responses, progress toward the treatment goal, and the plan for the next session.

Correct Billing

CPT 90847 with the MDD diagnosis. If same-day individual therapy also occurred, verify the payer's same-day billing policy before submitting both. Confirm family therapy authorization is current. Submit with documentation and auth number. No ambiguity, no missing pieces.

How Billing KPIs Show Up When CPT 90847 Is Done Right

When family therapy billing is working, you see it in the numbers. Clean claim rate on 90847 should hit 90%+ for well-run practices. If 90847 is denying at higher rates than individual therapy codes, that's a documentation or authorization workflow problem, not a clinical one.

AR days on family therapy claims correlate directly with authorization management speed. Practices that track family therapy authorization separately and renew proactively collect faster with less write-off. Practices without a clear workflow for it find it in AR aging at 90-120 days by which point recovery is harder and write-off is likely.

How Specialized Billing Support Helps With CPT 90847

Family therapy billing sounds simple and the underlying rule is. Patient present: 90847. Patient absent: 90846. The complexity is everything around that rule: payer-specific authorization requirements, same-day billing policies, diagnosis requirements, ongoing medical necessity documentation for long-term treatment.

General billing teams miss these in predictable ways. They don't track family therapy authorization separately. They don't catch documentation that implies but doesn't confirm patient presence. They resubmit denied claims without fixing the upstream problem.

A behavioral health-specialized team handles 90847 with payer-specific knowledge, pre-submission documentation review, and authorization tracking that keeps family sessions from hitting the wrong auth category.

Best Practices for CPT 90847 Billing

•       Require a participant list as a structured template field not narrative. Name every person in the room. This single change prevents the most common 90847 denial.

•       Track family therapy authorization separately from individual therapy. They're often separate categories at the payer level treating them as one is how sessions bill without coverage.

•       Check payer policy on same-day billing before the first combined claim. Individual + family therapy on the same date isn't automatically allowable everywhere. Know the rule before it shows up as a denial.

•       Quarterly note review: pull 10 random 90847 notes per provider and review against the documentation checklist. Catch patterns before a payer does.

•       When a 90847 claim denies, diagnose it before resubmitting. Documentation gap? Authorization lapse? Wrong diagnosis? Wrong code for patient absence? Each fix is different. Resubmitting the same claim generates the same denial.

Frequently Asked Questions About CPT 90847

Q1. What is CPT code 90847 used for?

CPT 90847 is the billing code for family psychotherapy with the patient present. A licensed mental health provider delivers active therapy to an identified patient in a family context — patient and family members together, with the family involved as part of the patient's treatment plan.

Q2. Can CPT 90847 be billed without the patient present?

No. Patient presence is the defining requirement. If family members attend without the identified patient, that's CPT 90846. Billing 90847 when the patient wasn't there is a coding error with audit exposure.

Q3. How long must a 90847 session be?

No AMA-defined time threshold it's a service, not a timed unit. Payers still assess clinical reasonableness, so an 8-minute session gets scrutinized. Most family therapy sessions run 45-60 minutes in practice. Some payers have their own internal duration guidelines, so check each payer's behavioral health policy specifically.

Q4. What is the reimbursement for CPT 90847?

Varies by payer, geography, and contracted rate. Generally comparable to or above 90834 in most markets. The practices collecting best on this code do so through clean claim rates not rate negotiation.

Q5. What is the difference between CPT 90846 and 90847?

One thing: patient presence. CPT 90847 has the patient in the session. CPT 90846 doesn't parent consultation, caregiver meeting, family session without the identified patient. Both are legitimate services. Wrong code for the wrong session creates compliance problems.

Q6. Why do insurers deny CPT 90847 claims?

Most common reasons: documentation doesn't confirm patient presence; medical necessity not established; family therapy authorization expired or missing; diagnosis code doesn't support the service; or same-day individual therapy policy was overlooked. Most 90847 denials are documentation or authorization problems — fixable upstream.

Wrapping It Up

CPT 90847 billing comes down to one fact patient present and documentation habits that either support that clearly or leave it ambiguous. The denial problems around this code are almost never clinical. They're about whether the note says what it needs to, whether authorization is current, and whether the billing team knows the payer-specific rules.
