CPT code 90847: family psychotherapy billing guide

Key Takeaways

CPT code 90847 is the AMA code for conjoint family psychotherapy where the identified patient is present during the session, lasting approximately 50 minutes.

The critical billing distinction: use 90847 when the patient participates, and 90846 when family meets without the patient – mixing these up is the top cause of claim denials for family therapy.

Medicare covers 90847 only when billed for an identified patient with a covered DSM diagnosis; it does not cover couples therapy as a standalone relationship counseling benefit.

Pabau’s claims management software automates CPT code assignment and links session documentation directly to the billing workflow, reducing the 90847/90846 mix-up at the source.

CPT code 90847: definition and clinical description

Most family therapy billing denials trace back to one error: the wrong code for patient presence. CPT code 90847 is the American Medical Association‘s designated code for conjoint family psychotherapy with the identified patient present. Get that distinction wrong on a single claim and you are looking at a denial, a corrected claim, and a delayed payment cycle that eats into your practice’s cash flow.

The official AMA descriptor reads: “Family psychotherapy (conjoint psychotherapy) (with patient present), 50 minutes.” That phrase “with patient present” is the billing trigger. The identified patient must be an active participant in the session, not simply in the waiting room. The session length is defined as approximately 50 minutes of face-to-face time, though time-based billing rules require at least 26 minutes of direct contact to bill the code.

CPT code 90847 applies to both couples therapy and family therapy, provided the patient with the covered diagnosis participates. Mental health practices billing this code serve a wide range of clinical presentations: substance use disorders with family involvement, adolescent behavioral conditions, mood disorders requiring family psychoeducation, and trauma treatment requiring conjoint work.

CPT code 90847 vs CPT code 90846: key differences

The 90847 vs 90846 distinction is where most billing errors originate. Both codes cover family psychotherapy sessions lasting approximately 50 minutes. The only difference is patient participation.

Both codes require an identified patient with a covered diagnosis as the clinical anchor for billing. Neither code can be submitted for a session where there is no identified patient – pure relationship counseling without a diagnosable condition is typically not a covered benefit under most payer plans.

Who can bill CPT code 90847?

Provider eligibility for CPT code 90847 depends on state licensing, payer credentialing requirements, and CMS enrollment rules. The following provider types generally qualify, though verification with individual payer contracts is always required before submitting claims.

• Licensed Psychologists (PhD, PsyD) – eligible to bill Medicare and most commercial plans for family psychotherapy
• Licensed Clinical Social Workers (LCSWs) – eligible under Medicare Part B following the mental health billing improvements in the Consolidated Appropriations Act
• Licensed Marriage and Family Therapists (LMFTs) – eligible for Medicare beginning January 1, 2024, under expanded mental health provider rules
• Psychiatrists and other physicians (MD, DO) – eligible across Medicare and commercial payers
• Licensed Professional Counselors (LPCs) and Licensed Mental Health Counselors (LMHCs) – eligible for Medicare beginning January 1, 2024; commercial payer eligibility varies by state and plan
• Psychiatric Nurse Practitioners (PMHNPs) – eligible under CMS rules, subject to state scope-of-practice requirements

Mental health practices using mental health EMR software that credentials providers accurately can avoid the billing errors that come from submitting claims under a provider type that is not credentialed for family therapy codes with a specific payer. State licensing board rules and individual payer contracts can further restrict which credentials qualify – always verify directly with the payer before the first claim.

CPT code 90847 reimbursement rates and fee schedule

Reimbursement for CPT code 90847 varies by payer, geographic location, and whether the session is delivered in a facility or non-facility setting. The figures below reflect the 2025-2026 Medicare Physician Fee Schedule (PFS); commercial payer rates are negotiated separately and may be higher or lower. Always verify current rates through the CMS Physician Fee Schedule lookup before billing.

These are approximate national averages. Geographic practice cost indices adjust Medicare rates by locality. Use the CMS fee schedule lookup with your specific ZIP code and provider specialty to pull the exact payment amount applicable to your practice. Commercial payers often reimburse at a multiple of the Medicare rate – typically 100% to 160% of Medicare – though this varies significantly by contract.

Medicare and Medicaid coverage for CPT 90847

Medicare Part B covers CPT code 90847 when it is medically necessary for an identified Medicare beneficiary who has a covered DSM diagnosis. The key compliance point: Medicare does not cover couples therapy as a standalone relationship counseling benefit. The session must be clinically indicated for the identified patient’s diagnosed condition, and the patient must be the focus of treatment – not simply a participant in a general relationship intervention.

Medicaid coverage varies by state. Some state Medicaid programs cover conjoint family therapy under behavioral health benefits; others restrict coverage to individual therapy codes or require prior authorization for family sessions. Check your state Medicaid program’s behavioral health billing manual before submitting 90847 claims to Medicaid.

Documentation requirements for CPT code 90847

Insufficient documentation is the second-most-common reason family therapy claims deny. For CPT code 90847, the clinical record must demonstrate both medical necessity and patient presence. Missing either element creates an audit risk even when the session was clinically appropriate. HIPAA documentation standards for medical offices require that session notes are maintained securely and contain enough detail to reconstruct the clinical encounter.

• Patient diagnosis – a current DSM-5 diagnosis code for the identified patient, documented in the active treatment plan
• Confirmation of patient presence – the note must explicitly state that the identified patient was present and participated in the session (this is the most frequently missing element)
• Session time – the start and stop time of face-to-face contact, totaling at least 26 minutes to qualify for the code
• Treatment plan linkage – the session note must tie to an active treatment plan that supports the medical necessity of family therapy for the identified patient’s condition
• Participants – identify all family members or individuals present in the session by relationship to the patient
• Clinical content – what was discussed, interventions used, and the clinical rationale for the conjoint format
• Provider signature and credentials – the rendering provider must sign and credential the note correctly for the payer

Practices maintaining medical billing compliance standards use session note templates that include a built-in patient-presence confirmation field. When that field is part of the standard note structure, therapists cannot complete documentation without actively confirming whether the identified patient attended. This removes the most common root cause of 90847 denials. Digital forms built into your practice management workflow can enforce this structure at the point of documentation, before the claim is ever submitted.

Can CPT code 90847 be billed for telehealth?

CPT code 90847 is eligible for telehealth billing under current CMS rules. The code was added to the Medicare telehealth services list during the COVID-19 Public Health Emergency and has been extended through subsequent legislation. However, telehealth coverage for family therapy codes should be verified against the current CMS telehealth services list each year, as congressional action determines the permanent status of these extensions.

When billing 90847 via telehealth, the claim must include the correct place-of-service code. Use POS 02 (telehealth provided other than in the patient’s home) or POS 10 (telehealth provided in the patient’s home) depending on where the patient is located during the session. An incorrect POS code is a straightforward denial trigger that has nothing to do with clinical appropriateness. Commercial payer policies on telehealth delivery for family therapy codes vary – some plans require audio-video delivery and will not accept audio-only for behavioral health codes. Confirm telehealth requirements with each payer before the session.

Using the interactive complexity add-on code (90785) with CPT code 90847

CPT code 90785 is an add-on code that can be appended to CPT code 90847 when one or more interactive complexity criteria are present in the session. Billing 90785 without meeting the specific clinical criteria is an audit risk – documentation must support each criterion claimed.

The AAPC’s CPT code reference identifies four conditions that qualify for the interactive complexity add-on. At least one must be present and documented in the session note.

• Maladaptive communication – using play equipment, physical devices, or interpreter services to overcome communication barriers between the patient and family members
• Third-party involvement – the involvement of a non-patient third party who is legally responsible for the patient, or who presents with behavioral challenges that significantly disrupt the session
• Caregiver-patient relationships – the patient has a co-morbid psychiatric or known medical disorder that affects the caregiver relationship and requires additional management
• Language or cultural barriers – the need for an interpreter or the management of significant cultural or linguistic differences that affect the therapeutic process

When all criteria are met and documented, appending 90785 to a 90847 claim is appropriate and will increase the reimbursement for the session. Practices that fail to document which specific criterion was present leave themselves exposed in an audit, even when the add-on was clinically justified.

CPT code 90847 vs other psychotherapy codes

Family therapy practitioners frequently need to select between codes across the broader psychotherapy code family. The table below covers the codes most commonly used alongside or instead of CPT code 90847.

The individual therapy codes (90832, 90834, 90837) are billed per patient and cannot be substituted for family therapy codes when additional family members are present. Billing 90837 for a session where the patient’s partner also participated, without using 90847, underbills the session and fails to accurately reflect the service delivered.

How to bill CPT code 90847 with practice management software

Manual CPT code selection during billing entry is where the 90847/90846 mix-up most often occurs. A therapist finishes a family session, hands off to a biller, and if the session type is not clearly captured in the documentation, the biller has to guess – or defaults to the same code used last time. The medical billing workflow breaks down at the handoff between clinical and administrative staff.

Practice management platforms that connect session type directly to billing can eliminate this gap. When a therapist logs a “conjoint family therapy – patient present” session type, the correct CPT code 90847 populates automatically. The session notes, time documentation, and patient-presence confirmation flow into the billing record without a secondary manual entry step.

Pabau’s claims management software connects session documentation to claim submission within a single workflow. Rather than exporting notes to a separate billing system, the clinical record – including the patient-presence confirmation and session time – attaches directly to the claim before it is transmitted. Practices using this approach reduce the manual touchpoints where coding errors enter the process. Submitted claims route through Pabau’s Claim.MD clearinghouse integration, which validates claims against payer edits before submission and returns electronic remittance data automatically. The electronic remittance advice workflow means denials are identified and actionable the same day they come back from the payer.

For therapy practices managing high session volumes, the superbill generation step is another area where manual work creates errors. Auto-populated superbills that pull from the confirmed session type, provider credentials, and diagnosis codes reduce the likelihood of submitting a claim for 90847 when the documentation supports 90846 instead. The therapy practice management workflow should connect every step from appointment type to claim submission without requiring a biller to reconstruct clinical context from scratch. A clearinghouse integration that scrubs claims before transmission catches payer-specific edit failures before they become denials.

Common billing mistakes with CPT code 90847 and how to avoid them

CPT code 90847 has a well-documented set of denial patterns. Each one has a specific prevention step.

• Billing 90847 when the patient was absent. The most frequent error. If the identified patient did not participate, the correct code is 90846. A session note that does not explicitly state patient presence creates ambiguity that auditors resolve against the provider.
• Missing patient-presence documentation. Even when the patient was present, if the note does not confirm it, the claim is vulnerable. Add a mandatory patient-presence confirmation field to your session note template.
• Billing without a treatment plan. Medicare and most commercial payers require the family therapy session to link to an active, documented treatment plan for the identified patient. A claim without this link fails medical necessity review.
• Incorrect time documentation. Sessions that run under 26 minutes of face-to-face time do not meet the code’s time threshold. Document start and stop times in every session note.
• Billing 90785 without meeting the criteria. The interactive complexity add-on requires one of four specific documented conditions. Appending it without clinical justification is an audit trigger.
• Using an uncredentialed provider. Submitting a 90847 claim under a provider who has not completed payer credentialing for family therapy codes results in an automatic denial.

Effective denial management for family therapy codes starts before the claim is submitted. Practices that audit a random sample of 90847 session notes monthly catch documentation gaps before they reach claims volume. When a denial does occur, the corrected claim should include the specific documentation element that was missing from the original submission. Payers re-adjudicate corrected claims – a well-documented appeal recovers revenue that a dismissive “denied” response leaves on the table.

Conclusion

The billing distinction between CPT code 90847 and 90846 is narrow, but the financial consequence of mixing them up is significant. Every denied claim for family therapy means a corrected submission, a delayed payment, and staff time spent on work that should never have been necessary.

Pabau’s claims management software connects session documentation to billing and claim submission in a single workflow, eliminating the manual handoff where 90847/90846 errors typically enter the process.
