Group and family therapy documentation: what 90853, 90847, and 90846 each have to prove

By Selam Koch, PMHNP-BC, founder of OneStep Scribe and practicing psychiatric nurse practitioner. Published September 2026.

Group, family, and couples work runs on a small set of codes, and most of the trouble in this area traces to one idea that is easy to state and easy to violate: the note belongs to one patient. Not to the group, and not to the family. Eight people in a therapy group produce eight notes in eight charts, each documenting a different person's treatment. Four people in a family session produce one billable service and one note serving the identified patient's treatment, and the other three are participants in that patient's care rather than patients of the session. If one of those participants is separately your patient, you still document in their chart what bears on their own care; the constraint is on what you report, not on whether you chart.

Clinicians who hold that firmly get most of the rest right on instinct. Clinicians who do not end up with one group summary pasted into eight charts, or a family note written as though the family were the patient, and in my experience both patterns are easy to spot once records are pulled. Payer rules diverge a great deal in this corner of behavioral health, so treat everything below as something to verify against your own plans.

What each code describes

These are paraphrases in my own words, read against the CPT 2026 manual. The controlling definitions live in the CPT manual for the year you are billing and carry qualifiers I am not reproducing, so check the book. Descriptors change between editions, and these codes are an example: the family codes were untimed before CPT 2022.

90849 is the exception in that table. Coverage for it is materially narrower than for the other three, and many payers, including some Medicare contractors, treat it as non-covered. Verify before scheduling multiple-family groups as a billable service.

One setting exception for 90853. Group psychotherapy furnished as a component of a partial hospitalization or intensive outpatient program is generally paid inside the program's per-diem and is not separately reportable by the practitioner. Confirm how your program bills before reporting 90853 for a group that runs inside it.

There is no separate code for couples therapy. When the work is family psychotherapy directed at one partner's diagnosed condition and treatment plan, it is reported under 90847 with that partner as the identified patient. Relationship counseling that is not treatment of a diagnosed condition in the identified patient is not a 90847 service, whatever the room looks like. Medicare in particular does not cover marital or relationship counseling that is not treatment of the beneficiary's condition. Coverage varies widely here: plans may require a covered diagnosis for that partner, exclude relationship problems as a standalone reason for the service, or exclude couples work outright. Confirm coverage before the first session.

The identified patient principle

Every psychotherapy note documents the treatment of one person, and the chart it sits in names that person. The modality can involve a room full of people; the subject of the note cannot. In group work the group is the vehicle and the patient is the subject. In family work the identified patient is the person whose plan the session serves and whose chart holds the note. Four consequences follow.

1. One note per patient, in that patient's chart, documenting that patient's participation, response, and progress against that patient's own goals, not the group's curriculum or the family's stated aims.
2. Other participants appear only as they bear on this patient. Their words and reactions enter the note when they change what you are doing for your patient, and not otherwise.
3. Attending does not make somebody a patient. No diagnosis for a family member in the identified patient's chart, no mental status exam of them, no treatment plan written for them there. The exception is safety and clinical necessity: observations about a participant that change your patient's risk picture, safety plan, or disposition belong in the note as observed session events, attributed and factual. Where your state imposes a mandatory-reporting or duty-to-warn or duty-to-protect obligation, that obligation governs. These duties are state-created and differ substantially: some states compel disclosure, many only permit it, some impose a duty to protect that a warning by itself does not discharge, and a few impose none at all. Mandatory-reporting triggers and reporter categories vary by state and by setting as well. Know your state's rule in advance rather than at the moment you need it.
4. If two people in the room are separately your patients, treat the conjoint session as one reportable service. That is the default, and it is how payers commonly treat it; a plan that has not published a position has not permitted a second claim. If you believe your situation is an exception, do not resolve it from a payer email or a phone call. Take it to your coding or compliance advisor, and document the basis in the record before you report anything twice.

What a group note has to contain

A defensible group note has a small shared part and a large individual part, and the ratio is the whole game. One or two sentences on the group's focus, then everything else about this member.

• Session logistics. Date, start and stop times or total duration, the format, who led it, and the participant count where the payer expects it.
• The group's clinical focus. One or two lines, and the only part that can legitimately look similar across charts.
• This patient's participation. What they brought, whether they engaged, deflected, dominated, or withdrew, specific enough that a colleague could pick this member out of the room.
• The interventions directed at this patient, not the group agenda, and this patient's response to them. In my experience the response is the element reviewers press hardest on and the one most often thin or absent.
• Progress toward this patient's own goals, named. A goal reference with a baseline beats a general statement of improvement; the mechanics are in the measurable treatment plan goals guide.
• Mental status and risk observations for this patient, brief and observed, and a plan covering continued participation, any assignment, and safety follow-through where the risk content calls for it.

Payers deny quietly on one distinction. The code describes psychotherapy. A group that delivers curriculum, or one the clinician moderates without intervening therapeutically, may not meet a payer's definition of the service however useful it is. The note should show intervention aimed at a clinical problem this patient has, not an agenda plus an attendance mark.

What an individualized group note looks like

The fictional excerpt below uses BIRP structure, Behavior, Intervention, Response, and Plan, which suits group work because it forces the individual elements into named sections. The variants are compared in the DAP, BIRP, and GIRP note examples.

Writing about the other people in the room

Confidentiality in this work is a documentation problem before it is anything else, because the chart is where a record about a non-patient gets created by accident. Five habits keep it clean.

• Never name a peer in a group note. The other members are separate patients of yours, and their identities do not belong in this patient's chart: no names, no identifying details, no reproducing what another member disclosed. Feedback exchanged in group is documented as your patient's response to it.
• In family and couples work, record participants by name and relationship where identification is required. Many payers and state Medicaid programs require it for 90846 and 90847, and naming a spouse or parent in the identified patient's own chart is generally appropriate under HIPAA, since the record documents that patient's treatment. What stays out is the participant's own clinical material: a spouse's history belongs there only to the extent it changes your patient's care, and where the parties are in conflict or separating, or intimate partner violence is a possibility, write on the assumption that the participant's words may reach the patient through their own record. Confirm your state's rule before adopting a naming convention, since some states require redaction of third-party information on release and state law or Part 2 may add restrictions.
• Attribute every statement to its speaker. "The patient's mother reports he has not slept in four days" and "patient denies sleep disturbance" are different objects, and risk content is where blurring them does the most damage. A family member's report is not the patient's endorsement, and their reassurance is not the patient's denial.
• Do not write a mental status exam of somebody who is not your patient. Noting that the patient's wife became tearful and stepped out documents a session event. Writing that she appeared depressed with constricted affect assesses a person who is not that chart's patient.
• Document the confidentiality frame you set. In family and couples work, what you will and will not hold privately. In group, that the limits were reviewed, including that members are not bound by the clinician's obligations.

What "psychotherapy notes" actually means, and why it probably does not cover this note

In my experience this is the provision misunderstood most often in exactly this setting. Clinicians frequently assume that group process content, peer disclosures, and family session narrative can be shielded from disclosure as psychotherapy notes. Usually they cannot.

The HIPAA Privacy Rule defines the term at 45 CFR 164.501. The operative language reads:

"Psychotherapy notes means notes recorded (in any medium) by a health care provider who is a mental health professional documenting or analyzing the contents of conversation during a private counseling session or a group, joint, or family counseling session and that are separated from the rest of the individual's medical record."

Quoted from 45 CFR 164.501. Read the full section, which contains qualifiers not reproduced here.

The separation is a condition, not a description: a passage sitting inside the progress note in the chart is not a psychotherapy note no matter what it contains.

The same definition then expressly excludes the items below, which remain part of the ordinary record. This is the regulation's list, quoted from the same section rather than summarized:

• "Medication prescription and monitoring"
• "counseling session start and stop times"
• "the modalities and frequencies of treatment furnished"
• "results of clinical tests"
• "any summary of the following items: diagnosis, functional status, the treatment plan, symptoms, prognosis, and progress to date"

Read that list against the group and family note this guide describes. Several of its elements sit in the excluded set regardless: start and stop times, modality and frequency, and any summary of diagnosis, treatment plan, symptoms, and progress to date. But the point that decides it is simpler than the content question. A passage sitting inside the chart is not separated, and separation is a condition of the definition.

So the note is very likely an ordinary progress note in the designated record set rather than a psychotherapy note, and it should be written on that assumption. That does not mean it is unprotected. It is fully protected PHI under the Privacy and Security Rules; what it does not carry is the heightened authorization requirement at 45 CFR 164.508(a)(2) that attaches to psychotherapy notes, and it is subject to the patient's right of access, from which true psychotherapy notes are excluded. Your state's mental health confidentiality law and 42 CFR Part 2 may protect the same note more strictly than HIPAA does. None of that is a release decision. Confirm with counsel before disclosing a group or family note in response to a records request or a subpoena.

If you also keep separate process notes, keep them genuinely separate, and understand that separation is a condition of the protection rather than a guarantee of secrecy. Even a properly separated psychotherapy note may be used or disclosed without authorization in the situations 45 CFR 164.508(a)(2) carves out, including required-by-law disclosures, disclosures to HHS for enforcement, health oversight of the originator, and defense of a legal action brought by the patient. A separated note is also reachable by court order. Separation does not make a note subpoena-proof or audit-proof, and it is not by itself a basis for withholding records from a valid request without legal advice.

The timing matters as much as the separation. Keeping process notes apart has to be your ordinary practice from the outset, established before anyone asks for the record. Reorganizing, moving, or separating material after a records request, a subpoena, or a litigation hold arrives is a spoliation problem, and it creates a far worse exposure than the one you were trying to manage.

The rules governing group confidentiality, disclosure to family members, minors' consent and access, and required releases are set by federal law (the HIPAA Privacy Rule, and 42 CFR Part 2, which applies to federally assisted programs that hold themselves out as providing substance use disorder diagnosis, treatment, or referral for treatment), state law, your licensing board, and your setting, and the state-level pieces differ substantially from state to state. Whether Part 2 applies turns on two questions: is the program federally assisted, a status that can follow from federal funding, tax-exempt status, DEA registration, or Medicare and Medicaid participation, and does it hold itself out as providing SUD diagnosis, treatment, or referral. Run that test for your own program rather than assuming either answer. Part 2 has historically carried disclosure and redisclosure restrictions stricter than HIPAA's. The February 2024 final rule, with a compliance date of February 16, 2026, aligned much of Part 2 with HIPAA, including a single patient consent that can cover future treatment, payment, and operations, and HIPAA-style breach notification and penalties. Part 2 still adds obligations on top of HIPAA, so confirm the current requirements as of your date of service. Consult a qualified attorney or compliance professional in your own jurisdiction. The above is documentation practice, not legal guidance.

90847, when the patient is in the room

The conjoint session is the more intuitive of the two family codes, and its failure mode is framing rather than content. It is still a psychotherapy note about one patient; what changes is that the material comes from an interaction rather than a report. Cover who was present by role, what the interaction revealed about the patient's clinical picture, the interventions you delivered into the system in service of the patient's goals, the patient's response, the family's response as it bears on that treatment, and the resulting plan.

Two things to avoid. The first is a transcript, a chronological account of who said what to whom, which runs long and documents little. The second is a note reading as though the couple or the family is the client, with goals written for the unit and no identified patient in it. If part of the session was individual and part conjoint, say so, because time attribution becomes live when two services are reported that day. Some plans allow both codes on one date, some bundle them, and some require authorization first, covered in the prior authorization guide.

90846, when the patient is not in the room

A conversation that was information exchange gets reported as psychotherapy. That is the misapplication I see most often with this code, and it runs almost entirely in that one direction. The code describes family psychotherapy directed at the identified patient's treatment, delivered to family members while the patient is absent. Reasons for the absence are often good ones: a young child, a patient too symptomatic to participate, family responses that are maintaining the symptoms, a transition where the environment has to change first. Five elements make the session a treatment service rather than a call.

1. Name the treatment plan goal the session serves. Not a general aim. A goal that exists in the patient's plan.
2. Document therapeutic intervention with the family. Coaching a parent through a different response to school refusal is intervention. Answering questions about a diagnosis is education, and education alone makes a weaker claim.
3. Document the family's response, including resistance, doubt, and partial agreement, which are often the most useful lines in the note.
4. State what changed in the patient's plan. A session that changed nothing about the patient's treatment is hard to describe as treatment of the patient.
5. Say why the patient was not present. One clause. It answers the reviewer's first question.

What this code is not: a collateral information-gathering call, a case-management conversation, or coordination with a school or agency. Those are real work, they belong in the chart, and they follow the conventions in the collateral contact documentation guide. Whether the patient's authorization or a signed release is required for family involvement, and what a minor's own consent changes, are state law questions. Get the answer for your state and record what is on file.

Time, duration, and where payers diverge

90853 carries no stated time. That does not make duration optional in the record. Document start and stop times or a total duration, and record the number of participants. Some state Medicaid programs cap group size and require the count in the note, some Medicare contractors address group documentation in local coverage material, and some boards have expectations independent of billing. I am not naming a specific manual section, LCD, or board rule here because they change and because yours is the one that governs you: search your own MAC's local coverage determinations and billing-and-coding articles for group psychotherapy, and search your state Medicaid behavioral health manual for group size and documentation requirements, before you rely on any of this.

The 90846 and 90847 descriptors state 50 minutes, with no approximation language, a time added in CPT 2022; before that the codes were untimed. Start from that number, because it is the only one CPT states here. CPT does not publish a code-specific time range for 90846 or 90847 the way it does for the individual psychotherapy codes 90832, 90834, and 90837, so there is no CPT-stated threshold beneath the stated 50 minutes for these codes. Some coders apply CPT's general midpoint convention to them anyway. That is a convention, not a CPT-stated threshold for these codes, and payers do not apply it uniformly: some payers and MACs have published their own minimum, some expect the full stated duration, some accept the midpoint reading, some are silent until they deny. Do not bill a shortened session against a minute figure you read in an article, mine included. Document actual time, and get your payer's written position before you rely on anything short of the stated 50.

Some of the rest is federal, and some is genuinely local. Do not treat the whole category as a matter of state law and contract.

Federal, for Medicare. Which practitioner types Medicare recognizes as billing providers is set by federal statute and regulation, but that is a floor rather than the whole answer, and it speaks only to Medicare. The practitioner must also be licensed and acting within scope under the law of the state where the service is furnished, MAC local coverage material can add conditions of its own, and state Medicaid rules and commercial credentialing separately control whether you can furnish these services and be paid for them outside Medicare. The change that matters most for family work: marriage and family therapists and mental health counselors became independently billable Medicare practitioners on January 1, 2024, which opened 90846, 90847, and 90853 to a large group of clinicians who previously could not bill Medicare at all.

Medicare telehealth coverage for behavioral health is likewise set by statute and CMS rulemaking rather than by contractor guidance, but do not read that as stability. The in-person visit requirement for tele-mental health has been delayed by Congress repeatedly and in short increments, and Medicare telehealth authority itself has lapsed and been restored more than once. Confirm the requirement's status as of your date of service before relying on it, and do not assume the position that held last quarter still holds.

Medicare "incident to" billing carries federal conditions no contract can loosen, though state law can cut the other way: state scope-of-practice rules can make incident-to unavailable where Medicare would otherwise permit it, because the auxiliary person must be legally authorized in the state to furnish the service. Incident-to is also a Part B office and non-facility construct. It does not reach services furnished in a hospital outpatient or other facility setting, and it does not govern commercial payers at all. Do not assume the general rule applies to the services this guide covers. The default condition is direct supervision, meaning the billing physician or NPP is present in the office suite and immediately available to furnish assistance and direction throughout the service, which is neither presence in the treatment room nor the clinical supervision your licensing board requires of a pre-licensed associate. But CMS created an exception allowing behavioral health services furnished incident to by auxiliary personnel under general rather than direct supervision, and CMS has at times allowed direct supervision itself to be met by real-time audio-video presence rather than physical presence. The supervision rules here have moved in successive Physician Fee Schedule rules and are among the provisions most likely to have changed since this was written, so verify the current-year PFS for the year you are billing before restructuring any staffing around either the rule or the exception. On the patient and problem conditions: CMS guidance in the Medicare Benefit Policy Manual, and the MAC articles built on it, is read to bar incident-to billing for a new patient or for an established patient presenting a new problem. The underlying requirement in regulation is that the billing physician performed the initial service and remains actively involved in the course of treatment. Check your own MAC's article for how it words this.

Local, and worth checking every time. How many sessions are covered before authorization, what supervision associate-level and pre-licensed clinicians require, what state Medicaid pays for and under what limits, and how commercial plans credential and contract for these services. Assume variation and verify.

When interactive complexity applies, and when it cannot

Interactive complexity can be reported alongside group psychotherapy under 90853 when a qualifying communication factor complicated delivery for one specific patient. It is patient-specific, not group-specific: it goes on that member's claim and is documented in that member's note, and naming the factor is not enough. The note has to show what the factor forced you to do differently.

It cannot be reported with the family psychotherapy codes. 90785 is an add-on code, and CPT designates the primary codes it may accompany: the diagnostic evaluation, the individual psychotherapy codes, psychotherapy with an E/M service, and group psychotherapy. Family psychotherapy with and without the patient present, and multiple-family group psychotherapy, are not on that list. Verify against the CPT manual for the year you are billing rather than taking my paraphrase for it. Claims pairing them are commonly rejected by claim edits, though behavior varies by payer and clearinghouse and some plans pay and recoup instead. The common reading, offered as interpretation rather than CPT's stated reasoning, is that managing family dynamics already sits inside those services. The qualifying situations are laid out in the 90785 interactive complexity guide.

Common denial patterns

• Identical notes across group members. Eight charts carrying one paragraph are eight notes documenting no individual treatment, and one chart pulled makes the rest worth pulling.
• No goal linkage. The note describes a session competently and never connects it to this patient's own plan.
• Attendance-only documentation. "Patient attended group and participated appropriately" names an event and documents no intervention, no response.
• The family written as the patient. No identified patient, goals belonging to the unit, a note that could be filed in any of four charts.
• A group documented as education. Curriculum plus attendance, with no intervention aimed at a clinical problem this patient has.
• The same conjoint session reported in two charts, where both partners are your patients and the encounter was one service.
• Interactive complexity on a family code. Commonly rejected by claim edits, and where it is not, some plans pay and later recoup.
• 90846 that reads like a collateral call. No goal, no intervention, no change to the plan.
• Missing duration or participant count where the payer requires it. A mechanical denial.
• Frequency patterns. A rate that does not match the panel can invite a records request even when the individual notes are sound.

Frequently asked questions

Can I write one group note and copy it into every member's chart?

No. A short shared line describing the group's focus is legitimate. Everything after it has to be about the individual member: what that person contributed, how they responded to the interventions directed at them, and where they stand against their own goals. In my experience identical notes across a group are among the findings a reviewer spots most readily, and because the pattern is visible across the whole batch, a reviewer who finds it in one chart has reason to look at the rest.

Who is the identified patient in a couples session?

One partner. The note lives in that person's chart, serves that person's plan, and carries that person's diagnosis. The other partner participates in the identified patient's treatment rather than becoming a patient of the session. Decide who holds the chart at the start of the work rather than at billing time, and verify coverage first, because plans differ widely on relationship-focused work.

Can I bill 90846 for a phone call with a patient's parent?

Usually not. The distinguishing feature of the code is therapeutic intervention with the family rather than information exchange. A call to gather history, answer questions, or coordinate logistics is a collateral contact. If it genuinely was psychotherapy, the note has to name the goal served, the intervention delivered, the family's response, and what changed in the plan. Phone and video delivery carry their own payer rules.

Can I report 90785 with a family therapy session?

CPT designates the primary codes that 90785 may accompany, and the family psychotherapy codes are not among them, whether the patient is present or not, nor is multiple-family group psychotherapy. Verify against the current CPT manual for the year you are billing. Claims pairing them are commonly rejected by claim edits, though behavior varies by payer and some plans pay and recoup instead. Interactive complexity can be reported with group psychotherapy under 90853 when a qualifying factor complicated the service for one specific patient, documented in that patient's own note.

Does a group note need a duration if the code has no time attached?

Document it anyway. The descriptor states no time, but many commercial payers, state Medicaid programs, Medicare contractors, and boards expect start and stop times or a total duration, and some expect the participant count. A note missing its duration is harder to defend and trivial to fix, so build it into the template.

Can two clinicians who co-lead a group each bill for it?

This is payer-specific and often not allowed. Many payers pay one clinician for a group session regardless of how many staff are in the room, some permit co-leader billing under defined conditions, and some are silent until they deny. Confirm the policy per plan before staffing a group with two billable clinicians.

Can I bill an individual session and a family session on the same day?

It depends on the payer, and denials are common. Some plans allow both on the same date when each is clinically necessary and separately documented, others bundle them, and others require a modifier or prior authorization. If you report both, the notes must be genuinely separate in time, content, and stated clinical reason.
