CPT code 90846 describes family psychotherapy without the patient present, billed for a session of approximately 50 minutes. A licensed behavioral health provider meets with a spouse, parent, or other family member while the identified patient stays out of the room, and the discussion still has to connect back to that patient’s diagnosed condition. Practices that bill mental health services see this code constantly, and it also draws more denials than almost any other family therapy code on the fee schedule.
What Does CPT Code 90846 Actually Cover?
The code applies when a provider works with family members to address dynamics, communication patterns, or caregiver behavior that affect the identified patient’s mental health treatment, and the patient does not attend the session. Common scenarios include coaching parents on behavioral interventions for a child’s diagnosis, helping a spouse understand a partner’s treatment plan, or working through caregiver burden that is interfering with a patient’s progress.
CPT 90846 is not a code for general relationship or marriage counseling. Every session has to tie back to the identified patient’s diagnosed condition and treatment goals. When a note reads like standalone couples counseling, payers routinely deny the claim or reclassify it under a relationship code that many plans exclude from coverage.
CPT 90846 vs. CPT 90847: What’s the Difference?
Both codes fall under the family psychotherapy family, and billers mix them up constantly. The distinction comes down to one factor: whether the identified patient is in the room.
| Element | CPT 90846 | CPT 90847 |
|---|---|---|
| Identified patient present? | No | Yes, for a meaningful portion of the session |
| Typical scenario | Parent or spouse session focused on the patient’s treatment | Conjoint family or couples session that includes the patient |
| Session length | Approximately 50 minutes (26-minute minimum) | Approximately 50 minutes (26-minute minimum) |
If the identified patient joins for any meaningful part of the session, most coding guidance points to 90847 instead of 90846. Reserve 90846 strictly for sessions where the patient is completely absent, and document that absence clearly.
How Long Does a 90846 Session Need to Last?
The official CPT descriptor lists 50 minutes, but most payers treat that as a typical length rather than a strict requirement. In practice, a session needs at least 26 minutes of documented face-to-face time to support the code. CMS family psychotherapy billing guidance record the actual start and stop time on every session regardless of length; a note without timestamps is one of the fastest ways to trigger a request for records.
Sessions that run long, generally past the 90-minute mark, may qualify for time-based add-on codes. Confirm with each payer before appending an add-on code, since coverage for extended family therapy time varies significantly by plan.
How Does Reimbursement Work for CPT 90846?
CPT 90846 is reimbursed like most time-based psychotherapy codes: Medicare and most commercial payers assign it a set of relative value units (RVUs) that translate into a dollar amount through each payer’s fee schedule, adjusted for geographic locality and the rendering provider’s license type. There is no single national rate. A practice’s actual allowable depends on its specific payer contracts, so check the CMS Physician Fee Schedule Look-Up Tool for Medicare and each commercial payer’s fee schedule before quoting a number to a client or provider.
Two things move the reimbursement conversation more than the base rate does: whether the claim is clean on first submission, and whether the practice is billing the right code for what actually happened in the room. A denied 90846 claim costs more in rework time than the difference between most payers’ allowables.
Who Can Bill CPT Code 90846?
State licensing rules and each payer’s credentialing policy determine who can render and bill this code. In most states, the following provider types bill 90846 when the service falls within their scope of practice:
- Licensed Clinical Social Workers (LCSW)
- Licensed Professional Counselors (LPC) and Licensed Mental Health Counselors (LMHC)
- Licensed Marriage and Family Therapists (LMFT)
- Clinical psychologists
- Psychiatrists and other prescribing behavioral health providers
- Psychiatric nurse practitioners, where state law permits
psychiatry and psychology services, Behavioral health billing carries its own coding and payer rules, separate from general medical billing, which is why many practices route this work through a mental health billing specialty team instead of handling it alongside standard claims.
What Documentation Do Payers Require for 90846 Claims?
Clean documentation is what separates a paid 90846 claim from a denied one. At minimum, each note needs:
- The identified patient’s name and diagnosis, even though the patient is not present
- Exact session start and stop time
- Names and relationship of every attendee
- The clinical focus of the session and interventions used
- A clear statement of how the session supports the identified patient’s treatment plan
- The patient’s ICD-10 diagnosis code, not a relationship-focused code
CMS outpatient psychotherapy documentation guidance a useful habit is writing the note so it would make sense to a reviewer who has never met the family: name the identified patient, state who attended in their place, describe the specific behavioral or communication issue addressed, and close with how that work supports the patient’s existing treatment plan. Vague summaries such as “family session, discussed progress” are a common reason payers request records or deny the claim outright.
Getting the CPT-to-ICD-10 pairing right on every claim is really a coding discipline problem more than a clinical one, and it’s the core of what our medical coding services team builds into a practice’s daily workflow.
Can You Bill CPT 90846 for Telehealth Sessions?
Many payers now reimburse 90846 delivered by real-time video, which is useful when family members live in different cities or states. Apply modifier 95 for synchronous audio-video sessions and the place-of-service code that matches where the patient is physically located. Some payers use a separate modifier for audio-only sessions. Telehealth and modifier policy changes often, so verify the current requirement with each payer before scheduling a remote family session rather than relying on last year’s rule.
Prevent Avoidable CPT 90846 Claim Denials
Family therapy claims like CPT 90846 are frequently flagged because of missing modifiers or diagnoses that do not clearly connect the service to the identified patient. Docscare reviews every behavioral health claim against payer-specific coding requirements, helping practices maintain a 99% clean claim ratio.
Why Do 90846 Claims Get Denied?
A handful of patterns account for most 90846 denials:
- The session is coded as general relationship counseling instead of tied to the identified patient’s diagnosed condition
- Missing or vague start and stop time documentation
- No clear statement connecting the session to the identified patient’s treatment plan
- Missing prior authorization, especially common with Medicaid managed care plans
- Same-day billing with individual therapy that lacks distinct, non-overlapping time and the correct modifier
- Exceeding a payer’s frequency limit for family sessions within a treatment episode
- A rendering provider’s credentials that don’t match the payer’s coverage policy for the code
These issues aren’t unique to family therapy. If you want the broader pattern, our breakdown of the top reasons insurance claims get denied walks through the same root causes across specialties. And if your practice is already sitting on a backlog of denied family therapy claims, that’s usually a job for dedicated denial management support rather than a one-off resubmission.
Tips for Getting 90846 Claims Paid on the First Try
- Verify eligibility and behavioral health benefits before scheduling a family session
- Confirm whether the payer requires prior authorization for family therapy
- Document exact start and stop time on every session, not just the CPT code
- Use the identified patient’s diagnosis code, not a relationship-focused code
- Apply the exact telehealth modifier and place-of-service combination the payer requires
- Keep 90846 and any same-day individual session clearly separated in the note, with distinct times
The single biggest lever for clean claims across CPT-based behavioral health codes is pairing the procedure code with the right diagnosis. Our comparison of ICD-10 and CPT codes takes a closer look at how the two systems work together.
Frequently Asked Questions

It’s used to bill a family psychotherapy session in which the identified patient does not attend, typically when a provider works with a spouse, parent, or other family member on issues connected to the patient’s mental health treatment.
How long does a 90846 session need to last?
The official descriptor lists 50 minutes, but most payers accept a minimum of 26 minutes of documented face-to-face time. Always record the actual start and stop time.
What is the difference between CPT 90846 and 90847?
90846 is billed when the identified patient is not present for the session. 90847 is billed when the patient is present, or joins for a meaningful portion of it.
Can CPT 90846 be billed via telehealth?
Many payers cover 90846 delivered by real-time video. Apply modifier 95 and the correct place-of-service code, and confirm each payer’s current telehealth policy before the session.
Why do 90846 claims get denied so often?
The most common reasons are missing time documentation, a diagnosis that reads as general relationship counseling rather than tied to the identified patient, and missing prior authorization.
Who is qualified to bill CPT 90846?
Licensed clinical social workers, licensed professional counselors, licensed marriage and family therapists, clinical psychologists, and psychiatrists typically bill this code when the service is within their scope of practice.
Can 90846 be billed on the same day as an individual therapy session?

CPT 90846 covers a genuinely important part of behavioral health treatment, and it also sits on a shorter list of codes that payers scrutinize closely. Precise documentation, the correct modifier, and a diagnosis code that clearly ties back to the identified patient are what keep these claims moving through the payer’s system instead of sitting in a denial queue.
Protect Your Practice’s Clean Claim Rate
When family therapy claims reduce your clean claim rate, the problem is often a coding or documentation gap—not a clinical one. Docscare specializes in behavioral health CPT and ICD-10 pairing, prior authorization tracking, and payer-specific modifier requirements for services such as CPT 90846.
